HS Code 2919Esters; phosphoric, and their salts, including lactophosphates, their halogenated, sulphonated, nitrated or nitrosated derivatives
2 six-digit codes · Heading 19 of 42 in Chapter 29 · World Customs Organization Harmonized System
HS code 2919 is where customs place phosphoric esters, also known as phosphate esters, and their salts. Use this page to see what the heading includes and how to pick the right six-digit code.
Heading 2919 splits exactly two ways. Goods answering to “Esters; phosphoric, and their salts, including lactophosphates, their halogenated, sulphonated, nitrated or nitrosated derivatives” classify either at 291910 or at 291990, and the wording in the table below is the whole of what separates them. The heading is number 19 of 42 in Chapter 29, Organic chemicals, which runs to 410 six-digit codes in all.
Six-digit codes under heading 2919
| HS Code | Import–export description |
|---|---|
| 291910 | Esters; phosphoric, and their salts, including lactophosphates, their halogenated, sulphonated, nitrated or nitrosated derivatives; tris(2,3-dibromopropyl) phosphate |
| 291990 | Esters; phosphoric, and their salts, including lactophosphates, their halogenated, sulphonated, nitrated or nitrosated derivatives; other than tris(2,3-dibromopropyl) phosphate |
What HS code 2919 covers
Lactophosphates are named in the wording, so they belong here too. Halogenated, sulphonated, nitrated or nitrosated derivatives of these goods are also included.
The number comes from the WCO Harmonized System, the shared code list used by customs offices around the world. Traders in India often say HSN code 2919. It is the same four digits.
Customs use this heading when a product is, at its core, an ester of phosphoric acid or a salt of one. It sits among the organic chemicals of Chapter 29.
What the heading wording means
The official text is long, but each part is simple. An ester is a compound made when an acid reacts with an alcohol. A salt of such an ester is the same kind of compound with a metal or similar partner attached.
The last part of the wording covers changed versions of these goods. Think of it as a short checklist:
- Halogenated: the molecule carries chlorine, bromine or a similar element.
- Sulphonated: a sulphur-based group has been added.
- Nitrated or nitrosated: a nitrogen-based group has been added.
- Lactophosphates: named on their own, so there is no doubt about where they go.
How to choose between 291910 and 291990
Phosphate esters tariff classification here comes down to one question. Is the product the dibromopropyl phosphate named in the 291910 row, or is it anything else in the heading?
Code 291990 is for every other good in the heading.
A short routine helps:
- Find the chemical name on the invoice or the safety data sheet.
- If it matches the chemical in the 291910 row, use 291910.
- If it is any other phosphoric ester, salt or derivative in the heading, use 291990.
- If the name fits neither, check the nearby headings below or try the HS code classifier.
Headings often confused with 2919
Several nearby headings sound alike. These cause most mix-ups.
- If the ester comes from a different inorganic acid, look there.
- HS 2923 covers quaternary ammonium salts and hydroxides, plus lecithins and other phosphoaminolipids. They contain phosphorus, but they are a different group of goods.
- They deal with organic acids, not esters of phosphoric acid.
Who imports and exports phosphoric esters (HS 2919)
Once you know the code, the next step is to see who trades it. Searching by code is a quick way to find importers and exporters of phosphoric esters. It also helps you build a list of suppliers and buyers, whether you sell these chemicals or source them. Import data and export data both start from the same four digits.

HS Code 2919: common questions
What is heading 2919?
It is the Harmonized System heading for phosphoric esters and their salts, with lactophosphates and chemically changed versions included.
What is the HS code for phosphoric esters?
The four-digit heading is 2919. Goods are then placed at 291910 or 291990, depending on the exact chemical.
What is the difference between HS 291910 and 291990?
Code 291910 holds one named chemical, the dibromopropyl phosphate in its row. Code 291990 holds all the other goods that fit the heading.
Are lactophosphates classified under HS 2919?
Yes. The heading wording names them directly. They go to 291990, since they are not the chemical named under 291910.
How can I find buyers and suppliers of phosphoric esters?
