HS Code 3914Ion-exchangers; based on polymers of heading no. 3901 to 3913, in primary forms
1 six-digit code · Heading 14 of 26 in Chapter 39 · World Customs Organization Harmonized System
HS code 3914 is where ion-exchange resins made from polymers are classified, as long as they are in primary forms. This page explains what fits, what does not, and where to look next.
Heading 3914does not subdivide further in the WCO nomenclature: goods answering to “Ion-exchangers; based on polymers of heading no. 3901 to 3913, in primary forms” classify at the single six-digit code 391400. The heading is number 14 of 26 in Chapter 39, Plastics and articles thereof, which runs to 131 six-digit codes in all.

What HS code 3914 covers
Heading 3914 is for ion-exchangers. These are goods based on polymers that belong in headings 3901 to 3913, and they must be in primary forms. In everyday trade talk, many people call them ion-exchange resins.
The number comes from the WCO Harmonized System, the shared system of tariff classification that customs offices use. Chapter 39, plastics and articles thereof, holds the plastics goods. Heading 3914 comes last among the headings for polymers in primary forms.
Traders in some countries call the same number the HSN code 3914. The heading number stays the same. Only the extra national digits and the rules around them can change.
Subheading 391400 and national tariff lines
At WCO level, heading 3914 has one six-digit subheading: HS 391400. This means you have no subheading to choose between. If the goods belong in 3914, your six digits are 391400.
Many countries add extra digits after the first six to build their own tariff lines. Those lines, and the duties tied to them, differ from country to country. Check the national tariff of the market you ship to before you fill in a customs form. We do not list duty or tax rates here.
How to classify ion-exchangers against nearby headings
Start with the base polymer. If it falls in one of the headings from 3901 to 3913, ask a second question: are the goods made to work as an ion-exchanger? If yes, and they are in primary forms, they go to 391400. If no, go back to the polymer heading.
Here is a quick guide to the choices around it.
When you are unsure, try the HS code classifier and confirm the result with your customs broker. Customs in your country has the final say.
- Ion-exchanger based on a polymer of 3901 to 3913, in primary forms: 391400.
- Plain polymer in primary forms that is not an ion-exchanger: the heading from 3901 to 3913 that matches the polymer type.
