How to Verify Suppliers Using Customs Shipment Data and Trade Records

How to Verify Suppliers Using Customs Shipment Data and Trade Records

Customs shipment data and trade records provide tangible proof of a supplier’s legitimacy by revealing their actual export history, product volumes, and buyer relationships. Unlike self-reported claims, these records are drawn from official customs filings, offering verifiable evidence of a supplier’s operations. By analyzing this data, you can confirm whether a supplier is genuinely active, consistent, and aligned with your sourcing needs.

The Power of Official Trade Records

Trade records act as a verification layer that goes beyond directories or supplier assertions. For example, suppose you are evaluating a potential supplier of industrial machinery. Their profile may claim years of experience, but customs data can show whether they have shipped similar products to other buyers, the frequency of those shipments, and the markets they serve. This data-driven approach eliminates guesswork and reduces the risk of partnering with unreliable or fraudulent suppliers.

Key Data Points for Verification

When reviewing customs shipment data, focus on the following elements to assess a supplier’s credibility:

• Shipment Frequency: Regular, high-volume shipments indicate a stable business.
• Product Consistency: Verify that the products they ship match their claimed offerings.
• Buyer Diversity: A supplier exporting to multiple countries or well-known buyers is more likely to be reputable.
• HS Codes: Cross-check the HS codes they use to ensure alignment with your product requirements.

By leveraging these insights, you can make informed decisions and avoid costly mistakes in your supply chain.

Why Traditional Supplier Directories Fall Short

Supplier directories are a common starting point for sourcing, but they often lack the rigor needed for thorough verification. Many directories allow companies to create profiles with minimal vetting, leading to unverified claims, outdated listings, and middlemen posing as manufacturers. This gap between presentation and reality can expose your business to significant risks.

The Problem with Self-Reported Claims

A supplier listed on a directory may claim to have exported thousands of units to global buyers. However, without access to customs data, there is no way to confirm whether these claims are accurate. For instance, a company might describe itself as a manufacturer when it is merely a trading intermediary. Or, it might list a long history of exports that no longer reflects its current operations. These discrepancies can lead to delays, quality issues, or even financial losses if the supplier fails to deliver as promised.

Limitations of Directory Verification

Directories often rely on self-reported information, which can be misleading or outdated. Some common issues include:

• Lack of Transparency: No visibility into actual shipment records or buyer relationships.
• Middlemen Disguised as Manufacturers: Trading companies may present themselves as producers, obscuring their true role.
• Inactive or Defunct Listings: Suppliers may remain listed long after they have ceased operations.

Why Data-Driven Verification Matters

To mitigate these risks, you need a verification process grounded in real, actionable data. Customs shipment data provides the missing link by offering concrete evidence of a supplier’s export history. For example, if a supplier claims to export ceramic tiles to Europe, trade records can confirm whether they have shipped those products, the quantities involved, and the countries they serve. This level of transparency is critical for making confident sourcing decisions.

By moving beyond directories and embracing data-driven verification, you can build a more reliable and resilient supply chain. Tools like trade data platforms empower you to validate suppliers with precision, ensuring that your business partners are as credible as they claim to be.

What Customs Shipment Data Reveals About a Supplier

Customs shipment data transforms supplier verification from a process of trust to one of evidence. Instead of relying on claims, you can examine real transaction records to assess a supplier’s credibility, capacity, and consistency.

Key Data Points and Their Significance

Each customs record contains structured fields that reveal critical insights about a supplier’s operations. Below is a breakdown of the most valuable data points and how they help you evaluate reliability.

For example, suppose you are sourcing ceramic tiles. If a supplier’s customs records show consistent HS code classifications for tiles, regular shipments to buyers in your target market, and volumes that align with their claimed capacity, you can be more confident in their reliability. Conversely, if their HS codes vary widely or their shipment history is sparse, it may be a red flag.

By analyzing these fields, you can build a data-driven profile of a supplier’s operations, reducing the risk of partnering with unreliable or fraudulent entities. For deeper insights, explore customs shipment data to see how these records can be leveraged in your verification process.

Step-by-Step Guide to Verifying a Supplier with Trade Data

Verifying a supplier using trade data is a structured process that ensures you base your decisions on facts, not assumptions. Follow this workflow to systematically assess a potential partner.

Identify the Supplier

Start by gathering basic details such as the supplier’s legal name, country, and claimed product range. Use this information to search for their trade records in a global trade data platform.

Cross-Reference Trade Records

Look for the supplier’s name in customs databases. Key actions include:

• Confirming their legal entity name matches the records.
• Checking if their claimed products align with the HS codes in their shipments.
• Verifying the timeframe of their export activity (e.g., recent shipments vs. outdated records).

Analyze Shipment Patterns

Examine the supplier’s trade history for consistency and reliability:

• Frequency: Regular shipments suggest a stable operation. Infrequent or sporadic activity may indicate a trading middleman rather than a manufacturer.
• Volumes: Compare declared quantities with the supplier’s claimed capacity. Large discrepancies could signal inflated claims.
• Buyer Diversity: A supplier exporting to multiple countries and buyers is likely more established than one with a narrow client base.

Validate Claims Against Data

Compare the supplier’s marketing statements with their trade records:

• If they claim to export to the US, confirm shipments to US ports.
• If they state a production capacity of 10,000 units monthly, check if their shipment volumes support this.
• If they list specific buyers, cross-reference these names with consignee details in the records.

Flag Potential Red Flags

Watch for inconsistencies such as:

• Mismatched HS codes (e.g., a supplier of electronics showing shipments of unrelated goods).
• No recent shipments despite claims of active exporting.
• Shipments only to a single buyer, which may indicate a shell company or middleman.

By following these steps, you can build a clear, evidence-based picture of a supplier’s legitimacy. For a deeper dive into how trade data can support your sourcing strategy, explore import data and export data resources.

The Three Types of Customs Data and When to Use Each

Supplier verification relies on customs data, but not all data is created equal. Understanding the differences between export data, import data, and destination-country import data helps you choose the right source for your needs.

Export Data

Export data comes from the supplier’s home country and shows what they shipped out. It’s useful for confirming a supplier’s export activity, product range, and volume. However, it may lack details on the final destination or buyer, as some records aggregate shipments or omit consignee names for privacy.

Import Data

Import data is recorded by the destination country and provides visibility into what was received. This is ideal for verifying shipments to your market, as it often includes the importer’s name, product descriptions, and values. The downside is that it only covers shipments entering that specific country, so it may miss exports to other regions.

Destination-Country Import Data

This is a subset of import data but is particularly powerful for cross-border verification. For example, if you’re sourcing from China, US import data can reveal Chinese suppliers shipping to American buyers. It’s often the most reliable way to confirm a supplier’s legitimacy, as it reflects real transactions cleared by customs.

Each type has trade-offs, so the best approach often combines them. For instance, start with export data to identify potential suppliers, then cross-check with import data from your target market.

How to Access Customs Shipment Data: Free vs. Paid Sources

Customs shipment data is available through free government sources and paid trade data providers, each with distinct advantages and limitations.

Free Government Sources

Government agencies like the US Census Bureau or China’s General Administration of Customs (GACC) publish trade statistics at no cost. These are reliable for high-level trends, such as total import/export volumes by country or product category. However, free data is often delayed (sometimes by months), aggregated, and lacks granular details like individual shipment records or buyer/supplier names.

Paid Trade Data Providers

Paid platforms offer deeper insights, including real-time or near-real-time updates, shipment-level details, and searchable databases. They provide access to bills of lading, HS codes, declared values, and consignee information, which are critical for supplier verification. The trade-off is cost, but the investment often pays off in reduced risk and better decision-making.

For most businesses, free data is a good starting point for market research, but paid tools are essential for thorough supplier verification. If you need to validate a supplier’s claims, customs shipment data from a paid provider will give you the clarity and precision required.

Red Flags in Trade Data That Signal Unreliable Suppliers

Supplier verification relies on spotting inconsistencies in customs shipment data before they turn into costly mistakes. Here are the key red flags to watch for:

Inconsistent Shipment Patterns

• Irregular volumes: Suppose a supplier claims to export 10,000 units monthly, but trade data shows only two small shipments in the past year. This mismatch suggests exaggerated capacity.
• Sudden drops: A supplier with steady exports that abruptly stop for months may have financial or operational issues.
• One-time spikes: A single large shipment followed by no activity could indicate a trading company liquidating stock rather than a stable manufacturer.

Suspicious Product and HS Code Mismatches

• Incorrect classifications: If a supplier’s declared HS codes don’t align with their advertised products, they may be misrepresenting their offerings.
• Overly generic codes: Using broad HS categories (e.g., "miscellaneous plastic products") instead of specific ones can hide the true nature of goods.
• Frequent code changes: A supplier switching HS codes for the same product may be trying to evade scrutiny or tariffs.

Missing or Incomplete Records

• No export history: A supplier with zero customs records despite claiming years of experience is likely a middleman or non-existent entity.
• Gaps in buyer data: If shipments lack identifiable consignees or show only vague destinations, the supplier may be obscuring their real client base.
• Incomplete documentation: Missing bills of lading, declared values, or container counts can signal incomplete or fabricated data.

High-Risk Geographic or Logistical Signals

• Unusual ports: Shipments routed through high-risk or sanctions-listed ports may indicate compliance issues.
• Single-buyer dependence: A supplier exporting 90% of their volume to one client may lack diversification, increasing your risk if that relationship ends.

Use trade data to cross-check these signals. If multiple red flags appear, proceed with caution or seek alternative suppliers.

Case Study: How Trade Data Exposed a Fake Manufacturer

A European importer was evaluating a Chinese supplier for bulk ceramic tiles. The supplier’s website listed a 20-year history, ISO certifications, and a long client list. However, the importer decided to verify these claims using customs shipment data before placing a large order.

The investigation began with a search for the supplier’s name in global trade databases. The results revealed no direct export records under their company name. This was the first warning sign. Next, the importer checked the supplier’s claimed factory address. Trade data showed that the address was registered to a trading company, not a manufacturing facility. The trading company had a history of exporting tiles, but the volumes were inconsistent with the supplier’s claims of producing 50,000 square meters monthly.

Digging deeper, the importer cross-referenced the supplier’s advertised HS codes for ceramic tiles with actual shipments. The data showed that the trading company had exported tiles under different HS codes, suggesting they were reselling products from other manufacturers rather than producing their own. Additionally, the consignee names in the trade records did not match the supplier’s listed clients. Some shipments were even labeled as "samples," indicating the trading company might have been testing the market rather than fulfilling large orders.

The final piece of evidence came from analyzing the frequency and volume of shipments. The trading company’s exports were sporadic, with long gaps between shipments and no clear pattern of growth. This was a far cry from the supplier’s claim of steady, high-volume production.

By piecing together these clues from import data and export data, the importer concluded that the supplier was not a manufacturer but a trading middleman. They avoided a costly mistake by switching to a verified producer with a transparent shipment history. This case highlights how trade data can uncover discrepancies that supplier directories and marketing materials often hide. Always validate claims with real customs records to ensure you’re working with a legitimate partner.

How to Verify Suppliers in High-Risk Regions or Industries

Verifying suppliers in regions with limited transparency or industries with complex supply chains requires a more strategic approach. High-risk regions, such as parts of Asia or Africa, often lack publicly accessible customs data, making traditional verification methods less effective. Similarly, industries like textiles, electronics, or pharmaceuticals may involve multi-tiered supply chains where the actual manufacturer is obscured by intermediaries.

Alternative Verification Tactics

When customs data is incomplete or unavailable, consider these steps to enhance your supplier verification process:

Leverage secondary data sources: Use trade associations, industry reports, or local business registries to cross-check supplier claims. For example, if a supplier claims to be a major exporter of textiles, verify their membership in industry groups or their presence in regional trade publications.

Conduct on-site or virtual audits: For high-value or critical suppliers, a physical or virtual factory audit can provide direct evidence of production capabilities. Many third-party inspection services specialize in verifying manufacturing operations in high-risk regions.

Request documentation: Ask suppliers for proof of past shipments, such as bills of lading, commercial invoices, or certificates of origin. While these documents can be falsified, inconsistencies or missing details can raise red flags.

Engage local partners: Work with trusted local agents or logistics providers who have firsthand knowledge of the market. They can help validate supplier claims and provide insights into their reputation.

In industries with complex supply chains, traceability is key. Use tools like HS codes to verify product classifications and ensure consistency with the supplier’s stated offerings. For example, if a supplier claims to export high-end electronics but their HS codes align with low-cost components, this discrepancy warrants further investigation.

Integrating Supplier Verification into Your Procurement Process

Building a repeatable supplier verification workflow ensures consistency and scalability, especially for businesses managing large supplier networks. Below is a template to streamline the process:

Roles and Responsibilities

• Procurement team: Identifies potential suppliers and initiates the verification process.
• Compliance team: Reviews supplier documentation and cross-checks against sanctions lists or trade restrictions.
• Data analysts: Use trade data platforms to validate shipment histories, product details, and buyer networks.
• Quality assurance: Conducts audits or inspections to verify production capabilities.

Tools and Resources

• Trade data platforms: Access customs shipment data to verify supplier claims with real shipment records.
• HS code classifiers: Use HS classifier tools to ensure product classifications align with supplier offerings.
• Documentation management systems: Store and track supplier certificates, audits, and other verification materials.

Verification Workflow

Scalability Tips

• Automate where possible: Use trade data APIs to pull shipment records directly into your procurement system.
• Standardize criteria: Develop a scoring system to rank suppliers based on verification results.
• Regular reviews: Re-verify suppliers annually or when significant changes occur (e.g., new products, markets).

By integrating these steps into your procurement process, you can ensure that supplier verification is both thorough and efficient, reducing risks and improving decision-making. For a deeper dive into how trade data can support your workflow, explore our trade desk services.

Common Mistakes to Avoid When Using Trade Data for Verification

Supplier verification using trade data is powerful, but it’s easy to make costly errors if you don’t approach it carefully. Here are the most common pitfalls to watch for:

• Relying on a single data source: Some platforms may only cover certain countries or shipment types. If you only check one source, you might miss critical records. Cross-reference with multiple providers to ensure completeness.

• Misinterpreting HS codes: HS codes can be broad or highly specific. Assuming a supplier only deals in one category because of a single code can lead to false conclusions. Always verify the full product description and check for related codes.

• Ignoring seasonal fluctuations: Shipment volumes can vary due to holidays, industry cycles, or economic conditions. A temporary dip in exports doesn’t necessarily mean a supplier is unreliable. Look at long-term trends instead of short-term anomalies.

• Overlooking buyer networks: A supplier with a strong history of exports to one country might not be experienced in your target market. Check their buyer diversity to gauge their adaptability and reliability.

• Neglecting data freshness: Trade data can lag behind real-time activity. Always confirm the recency of the records you’re reviewing to avoid outdated insights.

• Assuming all shipments are equal: A high volume of small shipments doesn’t always indicate a stable supplier. Focus on consistency, buyer reputation, and the nature of the goods shipped.

Advanced Tactics: Combining Trade Data with Other Verification Methods

Trade data is a cornerstone of supplier verification, but the most robust approach layers it with other due diligence methods. By integrating multiple sources, you create a 360-degree view of a supplier’s reliability and legitimacy.

Factory Audits and On-Site Visits

While trade records confirm a supplier’s export history, factory audits validate their operational capacity. Suppose you’re sourcing ceramic tiles. Trade data might show consistent shipments, but an on-site visit reveals outdated machinery or poor labor conditions. Combining both ensures you’re not just verifying past performance but also future capability.

Certifications and Compliance Checks

Certifications like ISO, CE, or FDA approvals add another layer of trust. Cross-reference a supplier’s claimed certifications with trade data to see if their shipments align with regulated products. For example, if a supplier exports medical devices, their customs records should reflect compliance with relevant standards.

Sanctions and Watchlist Screening

Even a supplier with a clean trade history could pose risks if they’re linked to sanctioned entities. Use sanctions lists to screen suppliers against global restrictions. Trade data can help identify red flags, such as sudden changes in shipping routes or unusual buyer networks, which may warrant further investigation.

Financial and Legal Verification

Trade data doesn’t always reveal financial stability or legal disputes. Pair it with financial reports, credit checks, or legal filings to assess a supplier’s long-term viability. A supplier with strong export records but pending lawsuits might not be a safe bet.

Continuous Monitoring

Supplier verification isn’t a one-time task. Use trade data to set up alerts for changes in a supplier’s shipment patterns, such as new buyers or declining volumes. This proactive approach helps you address potential issues before they impact your supply chain. For a streamlined workflow, consider integrating these methods into your trade desk process.

Getting Started: Your First Supplier Verification with Customs Data

Supplier verification doesn’t have to be complex. With the right approach, you can quickly confirm a supplier’s legitimacy using customs shipment data and trade records. Here’s a 5-step checklist to get started today, even with free or trial access to trade data.

Quick-Start Checklist

• Identify the supplier’s legal name and country: Start with the exact business name and location. Many suppliers operate under multiple names, so verify the official registration details.

• Search for their shipment history: Use a trade data platform to look up the supplier’s export records. Focus on recent shipments (last 12-24 months) to assess current activity. If no records appear, proceed with caution.

• Cross-check product and HS code alignment: Compare the supplier’s claimed products with their actual shipments. If they say they export ceramic tiles but their HS codes show only textiles, there’s a mismatch worth investigating.

• Review buyer and volume trends: Look for consistent buyers and shipment volumes. A supplier with sporadic or declining activity may not be reliable. Conversely, a steady flow of shipments to reputable buyers is a positive sign.

• Validate logistics details: Check the ports, shipping lines, and destinations in their records. This helps confirm their operational capacity and market reach.

Next Steps

If the supplier passes these checks, dig deeper into their trade patterns. If red flags appear (e.g., no records, inconsistent data), consider alternative suppliers. For a more structured approach, explore our customs shipment data tools to streamline verification.

This process turns supplier verification from a guess into a data-driven decision. Start with one supplier today and refine your method as you go.

Step-by-Step Checklist for Supplier Verification with Trade Data

Verifying a supplier with customs shipment data is systematic. Follow this checklist to ensure you cover all critical steps without missing red flags.

1. Gather Basic Supplier Details Start with the supplier’s legal name, registered address, and tax ID (if available). Cross-check these against official business registries. Discrepancies here (e.g., a mismatch between the provided address and the one in trade records) are immediate warning signs.

2. Pull Customs Shipment Records Use the supplier’s name or identifier to search trade databases. Look for:

• Frequency of shipments (consistent activity suggests stability)
• Volume trends (sudden drops may indicate operational issues)
• Product categories (ensure alignment with their claimed capabilities)

3. Validate Shipper/Consignee Roles Confirm whether the supplier appears as the exporter (shipper) or importer (consignee). A genuine manufacturer should primarily ship goods, not just receive them. If they only appear as consignees, they may be a trader, not a producer.

4. Check Trade Partners Review their most frequent buyers and suppliers. A network of reputable counterparts adds credibility. Conversely, if their top partners are obscure or flagged in sanctions lists, proceed with caution.

5. Assess Product Consistency Compare the HS codes in their shipments with their product catalog. For example, if a supplier claims to produce stainless steel pipes but their shipments are classified under plastic goods, this inconsistency demands clarification.

6. Verify Logistics Patterns Look for unusual shipping routes or transshipment hubs. Direct shipments to major markets are typical for established suppliers. Frequent use of high-risk ports or indirect routes may indicate smuggling or evasion.

7. Cross-Reference with Financial Data Some trade data providers include declared shipment values. Compare these with the supplier’s reported revenue or production capacity. Large discrepancies (e.g., declared values far below market rates) may suggest under-invoicing or fraud.

8. Document and Flag Anomalies Create a report with your findings. Highlight any inconsistencies for follow-up, such as:

• Missing or incomplete shipment records
• Inconsistent product descriptions
• Unverified trade partners

By methodically working through this checklist, you’ll build a data-backed profile of the supplier’s legitimacy. For deeper analysis, combine this with trade desk insights to validate their market position.

Common Mistakes to Avoid When Using Trade Data for Verification

Even experienced procurement teams make errors when leveraging customs data for supplier verification. Avoid these pitfalls to ensure accuracy and efficiency.

Overlooking Name Variations Suppliers may appear under slightly different names in trade records due to translations, abbreviations, or legal entity changes. For example, "ABC Manufacturing Co. Ltd." might also be listed as "ABC Mfg." or "ABC Corp." Always search for variations to capture the full picture. Use fuzzy matching tools if your trade data provider offers them.

Ignoring Low-Volume Shipments Some teams dismiss suppliers with few shipments, assuming they’re insignificant. However, low volume could indicate a niche producer or a new entrant. Instead of discarding them, investigate further. Check if their shipments align with their claimed specialties or if they’re testing new markets.

Relying Solely on Aggregate Data Aggregate trade data (e.g., total exports by country) won’t verify a specific supplier. You need shipment-level records to confirm details like product types, quantities, and trade partners. Always drill down to the transactional level for precise verification.

Assuming All Data is Current Customs records can lag by weeks or months. A supplier’s recent activity might not yet appear in the database. Supplement trade data with real-time checks, such as:

• Requesting recent commercial invoices
• Verifying production schedules via factory visits
• Checking industry reports for updates

Misinterpreting HS Codes HS codes can be broad or highly specific. A supplier shipping under a general code (e.g., "machinery parts") might not be transparent about their actual products. Use an HS classifier to decode the categories and ensure they match the supplier’s offerings. Misclassification can also be a red flag for customs evasion.

Neglecting the Bigger Picture Trade data is powerful but not infallible. Combine it with other verification methods, such as:

• Factory audits or virtual tours
• Third-party certifications
• Financial health checks

For example, a supplier with consistent shipment records but poor credit ratings may still pose risks. Use customs shipment data as one layer in a multi-faceted approach.

By sidestepping these mistakes, you’ll extract maximum value from trade data while minimizing false positives or negatives in your supplier verification process.

Step-by-Step Checklist for Supplier Verification with Trade Data

Verifying suppliers with customs shipment data is systematic. Follow this checklist to ensure you cover all critical steps and avoid oversight.

Pre-Verification

• Define your criteria: volume capacity, product consistency, compliance history.
• Identify the supplier’s legal name and registered address (not just trading names).
• Confirm their HS codes align with your product category using our HS classifier.

Data Collection

• Pull the supplier’s import and export records for the past 12-24 months via customs shipment data.
• Cross-check their declared product descriptions against your requirements (e.g. suppose you export ceramic tiles, ensure their records show consistent HS 6907 or 6908 classifications).
• Note the frequency and volume of their shipments to gauge production scale.

Analysis

• Verify consistency: Do their shipment volumes match their claimed capacity?
• Check for red flags: sudden drops in activity, mismatched product labels, or frequent changes in consignee details.
• Assess geographic spread: A legitimate supplier should have a logical distribution pattern (e.g. regular exports to major markets).

Validation

• Compare their trade data with their provided references or certificates.
• Use sanctions lists to screen for restricted entities or individuals.
• Calculate their average landed cost per shipment to spot pricing anomalies.

Final Steps

• Document discrepancies and request explanations from the supplier.
• Re-run the check quarterly for high-value suppliers.

Common Mistakes to Avoid When Using Trade Data for Verification

Even experienced procurement teams can misinterpret trade data. Here are the most frequent pitfalls and how to sidestep them.

Overlooking Trading Names vs. Legal Entities Many suppliers operate under multiple trading names. Relying on a brand name without confirming the registered legal entity can lead to false matches. Always verify the exact company name in the customs records.

Ignoring HS Code Mismatches Suppose a supplier claims to produce stainless steel pipes (HS 7304) but their records show frequent shipments under HS 7208 (flat-rolled steel). This inconsistency could indicate misclassification or a front company. Use our HS codes tool to validate classifications.

Assuming Volume Equals Reliability High shipment volumes don’t always mean a trustworthy supplier. A factory could be exporting low-quality goods in bulk. Pair volume data with buyer feedback, product samples, and compliance checks.

Neglecting Seasonal or Market Fluctuations Trade data can vary due to seasonal demand or economic shifts. A temporary drop in shipments might not be a red flag if it aligns with industry trends. Cross-reference with global trade data for context.

Skipping Sanctions and Compliance Checks Even if a supplier’s trade data looks clean, they might be linked to restricted entities. Always screen against sanctions lists before finalizing contracts.

Relying on Free Data Only Free trade data sources often lack depth or updates. For critical verifications, use paid trade data providers to access granular details like consignee addresses and exact shipment values.

Hypothetical Example: Using Trade Data to Verify a Ceramic Tile Supplier

Suppose you are sourcing ceramic tiles from a potential supplier in Vietnam. Their website looks professional, their prices are competitive, and their certifications appear valid. But before placing an order, you want to verify their legitimacy using customs shipment data.

Start by checking the supplier’s name and address against trade records. If the supplier is genuine, you should find multiple shipments under their exact legal name. For example, if their registered name is “Vietnam Ceramics Co. Ltd,” search for this in the importer and exporter fields. A red flag would be no records or shipments listed under a slightly different name, like “Vietnam Ceramic Exports.”

Next, examine the shipment details. Look for consistency in the volumes, destinations, and frequency of their exports. A reliable supplier should have a steady flow of shipments to multiple buyers, not just one or two occasional transactions. If the data shows they only exported a single container of tiles six months ago, this could indicate they are a trading company rather than a manufacturer.

Check the HS codes of their shipments. Ceramic tiles typically fall under HS code 6907 or 6908. If their exports are classified under unrelated codes, this could signal misclassification or an attempt to obscure their actual business.

Finally, cross reference their declared production capacity with actual shipment volumes. If they claim to produce 10,000 square meters of tiles monthly but only export 1,000, this discrepancy warrants further investigation.

By methodically analyzing these data points, you can confirm whether the supplier is legitimate or if further due diligence is needed. For more on interpreting HS codes, see our HS classifier tool.

Common Mistakes to Avoid When Using Trade Data for Supplier Verification

Using trade data for supplier verification is powerful, but it is easy to make mistakes that lead to false conclusions. Here are the most common pitfalls and how to avoid them.

Relying on partial or outdated data Some trade data providers offer limited datasets that exclude certain countries or time periods. Always ensure your data covers the supplier’s primary markets and recent activity. For example, if you are verifying a supplier in India, but your data only includes US imports, you may miss critical shipments to other regions. Use a global trade data source to get a complete picture.

Ignoring name variations Suppliers often operate under multiple names or slightly different spellings. A company might export under “ABC Ceramics” but import raw materials as “ABC Ceramics Vietnam.” Failing to account for these variations can lead you to overlook relevant shipments. Use fuzzy matching or wildcard searches to catch all possible name formats.

Overlooking indirect shipments Not all shipments are direct. Some suppliers use intermediaries or consolidators, which means their name may not appear as the exporter. For instance, a manufacturer might ship goods to a trading company, which then exports them under its own name. To uncover these relationships, look for patterns in shipment volumes, destinations, and HS codes. If a trading company suddenly starts exporting large quantities of ceramic tiles, it may be sourcing from your supplier.

Misinterpreting HS codes HS codes can be complex, and misclassification is common. For example, ceramic tiles might be classified under multiple subheadings depending on their material or finish. If you are not familiar with the HS codes for your product, use our HS classifier tool to ensure accuracy. Misinterpreting codes can lead you to miss shipments or draw incorrect conclusions.

Focusing only on export data While export data is valuable, it only tells part of the story. A supplier’s import records can reveal their raw material sources, production scale, and supply chain stability. For example, if a tile manufacturer imports large quantities of clay, this supports their claim of being a producer rather than a trader. Always analyze both import data and export data for a complete view.

Avoiding these mistakes ensures your supplier verification process is thorough and reliable. For a structured approach, see our step-by-step guide to verifying suppliers with trade data.
