HS Code 2904Sulphonated, nitrated or nitrosated derivatives of hydrocarbons; whether or not halogenated
10 six-digit codes · Heading 4 of 42 in Chapter 29 · World Customs Organization Harmonized System
HS code 2904 is for organic chemicals made by adding sulpho, nitro or nitroso groups to a hydrocarbon. Use this page to see what fits and how to pick the right subheading.
Heading 2904 is finely cut: 10 six-digit codes, 290410 to 290499, all of them under “Sulphonated, nitrated or nitrosated derivatives of hydrocarbons; whether or not halogenated”. At that depth it is the exact wording of the code, not of the heading, that settles a classification. The heading is number 4 of 42 in Chapter 29, Organic chemicals, which runs to 410 six-digit codes in all.

What HS code 2904 covers
Heading 2904 holds organic chemicals built from a hydrocarbon. A hydrocarbon is a compound made only of carbon and hydrogen. Swap some of that hydrogen for another group and you get a derivative.
Here the added group is a sulpho group (sulphur and oxygen), a nitro group (nitrogen and oxygen) or a nitroso group. The words sulphonated, nitrated and nitrosated each name one of these. Halogens such as chlorine or fluorine may also be present. The product still belongs here.
The Harmonized System is the shared product list that customs offices use. India calls the same heading HSN code 2904.
How to choose the right 2904 subheading
Start with the named substances, because they have codes of their own. Leave the catch-all code for last. If a product mixes different groups, the "only" codes may not fit, so read the wording closely.
National tariffs often split 290410 into finer lines. Check your local tariff too. The HS code classifier can help when the wording is unclear.
- 290432 to 290435: salts of PFOS, namely ammonium, lithium, potassium and other salts.
- 290436: perfluorooctane sulphonyl fluoride.
- 290491: chloropicrin, also called trichloronitromethane.
- 290499: any other product that fits the heading.
HS 2904 vs 2903 halogenated derivatives
Heading 2903 is the home of products that carry halogens and nothing else added. Once a sulphur or nitrogen group is present, the product moves to 2904, even if halogens remain.
Other nearby headings start from a different base. Heading 2902 holds cyclic hydrocarbons before any group is added. Heading 2908 does the same job for phenols.
So ask what the base compound is. A plain hydrocarbon base points to 2904. An alcohol or phenol base points to one of the other headings.

HS Code 2904: common questions
What does HS 2904 cover?
It covers hydrocarbon derivatives that carry an added sulphur-oxygen or nitrogen-oxygen group. Halogens may or may not be present.
What is the HS code for PFOS?
Its salts and its sulphonyl fluoride sit in 290432 to 290436.
What is the HS code for chloropicrin?
Chloropicrin, also named trichloronitromethane, is classed under 290491.
What is the difference between HS 2903 and 2904?
2903 is for derivatives that have halogens only. 2904 is for those that also carry a sulphur or nitrogen group, whether or not halogens are present.
How often is HS 2904 trade data updated?
It depends on the market. The records section above gives the schedule.
