HTS US: 2904.XX.XXXX
Description
HTS Code 2904 encompasses a range of chemical derivatives of hydrocarbons that have undergone modification through sulfonation, nitration, or nitrosation processes. These derivatives may or may not be halogenated and include their salts and ethyl esters. The heading is subdivided into categories based on the type of functional group present:
- Derivatives containing only sulfo groups – These include sulfonic acids, their salts, and ethyl esters.
- Derivatives containing only nitro or only nitroso groups – Compounds with nitro (-NO2) or nitroso (-NO) substituents on aromatic or other hydrocarbon structures.
- Other derivatives – Including perfluorooctane sulfonic acid and its salts, as well as other miscellaneous compounds.
Code Hierarchy
- Section VI: Products of the Chemical or Allied Industries (Chapters 28-38)

What is NOT Classified Here?
To ensure correct classification, note the following exclusions from this heading:
- Compounds not derived from hydrocarbons are classified elsewhere.
- Derivatives containing other functional groups not limited to sulfo, nitro, or nitroso groups fall under different headings.
- Non-halogenated vs. halogenated status is covered inclusively under this heading, but compounds primarily halogenated without the specified functional groups are elsewhere.
Notes
- Regulatory Considerations: Many of these compounds are used in industrial chemical synthesis, dyes, pharmaceuticals, and specialty chemicals, and may be subject to import/export controls or environmental regulations.
- Duty Rates: Duty rates vary by specific HTS code depending on the compound and its use; consult the latest USHTS for precise tariff information.
- Additional U.S. Notes: Certain products under this heading are subject to special provisions as per U.S. note 3 to section VI.
