HS Code for Cationic surfactant

Cationic surfactants are classified under HS code 3402.41 because they are organic surface-active agents where the hydrophilic part of the molecule carries a positive charge (cation) when dissolved in water. These substances are distinct from soaps and are primarily used for their unique properties such as fabric softening, hair conditioning, and antimicrobial action. The classification within heading 3402 is determined by the chemical nature of the surfactant's active component. Under the 2022 HS nomenclature updates, the subheadings for surface-active agents were restructured, and 3402.41 specifically captures those of a cationic nature that are not put up for retail sale as finished detergents, although the code also covers them if they are. The classification is based on the chemical structure rather than the final application, provided the product meets the criteria for an organic surface-active agent as defined in the Chapter 34 legal notes.

Products Included

• Quaternary ammonium salts
• Benzalkonium chloride
• Cetyltrimethylammonium bromide (CTAB)
• Stearalkonium chloride
• Fatty amine salts used as surfactants

Common Misclassification

Cationic surfactants are often confused with 3402.42 (anionic) or 3402.49 (non-ionic) surfactants. Another common error is 3808.94 if the product is marketed primarily as a disinfectant rather than a surface-active agent. Additionally, if the product is a finished washing preparation containing these agents, it may be moved to 3402.90.

FAQ

What is the HS code for cationic surfactant?

The primary HS code for cationic organic surface-active agents is 3402.41.

Difference between 3402.41 and 3402.90?

3402.41 is for the chemically defined surface-active agent itself, while 3402.90 is for surface-active preparations or washing preparations that contain these agents mixed with other ingredients.
