HS Code for Surface active agent

Surface active agents, or surfactants, are classified under HS code 3402.49 when they are organic and not specifically identified as anionic, cationic, or non-ionic in previous subheadings. This classification falls under Chapter 34, which encompasses soap, organic surface-active agents, and washing preparations. The determination for 3402.49 is based on the chemical structure of the molecule, which must contain one or more hydrophilic and lipophilic groups capable of reducing surface tension. This specific code serves as a residual category for amphoteric agents or complex organic mixtures that do not fit the criteria for the more specific subheadings 3402.41 through 3402.43. Proper classification requires technical data sheets confirming the organic nature of the agent and its intended use as a raw material rather than a finished retail product.

Products Included

• Amphoteric surface-active agents
• Zwitterionic surfactants
• Industrial wetting agents (organic)
• Emulsifiers for industrial chemical synthesis
• Dispersing agents for aqueous systems

Common Misclassification

A common error is classifying these agents under 3402.50, which is reserved for surface-active preparations put up for retail sale. HS code 3402.49 is strictly for the agents themselves, often in bulk or industrial packaging. Another confusion occurs with 3824.99 (miscellaneous chemical products), but if the product's primary function is surface activity, Chapter 34 takes precedence according to the Section VI notes of the Harmonized System.
