HS Code 34.02 – Organic surface-active agents (not soap); surface-active, washing (including auxiliary washing) and cleaning preparations, containing soap or not, excluding those of heading no. 3401

HS code 3402 is a 4-digit heading in the Harmonized System that covers: Organic surface-active agents (not soap); surface-active, washing (including auxiliary washing) and cleaning preparations, containing soap or not, excluding those of heading no. 3401. Heading 3402 is dedicated to organic surface-active agents (excluding soap) and a wide array of surface-active, washing, and cleaning preparations. This is a critical and expansive classification in international trade, encompassing products used for various cleaning purposes beyond personal skin washing. It includes both pure surface-active agents (surfactants) and finished cleaning preparations, whether or not they contain soap. The key distinction from 3401 is that products under 3402 are generally not intended for use 'as soap' for skin cleansing but rather for household, industrial, or institutional cleaning, or as auxiliary washing preparations. This heading covers detergents, wetting agents, emulsifiers, dispersants, and other preparations designed to modify surface tension. Its scope is broad, ranging from laundry detergents and dishwashing liquids to industrial degreasers and specialty cleaning formulations. For trade compliance, understanding the primary function and composition is paramount to differentiate it from soap (3401), certain chemical preparations (3824), or even disinfectants (3808). This heading forms a crucial part of Chapter 34, covering the vast segment of the chemical industry focused on cleanliness and surface modification, playing a vital role in consumer goods and industrial applications worldwide.

Laundry detergent powder, liquid laundry detergent, fabric softener, dishwashing liquid (machine), dishwashing liquid (hand, not for skin), all-purpose cleaner spray, carpet shampoo, oven cleaner, toilet bowl cleaner, glass cleaner (non-polish), car wash soap, industrial degreaser, floor cleaner concentrate, wetting agents for agriculture, emulsifiers for food processing, dispersants for paint, textile scouring agents, laboratory cleaning solutions, stain removers for laundry, household bleach (with surfactants), enzymatic cleaners, car interior cleaner, pressure washer detergent, concrete cleaner, drain opener (detergent-based).

Traders often confuse 3402 with 3401 (soap) if the product has any cleansing property; however, 3402 explicitly excludes soap for skin washing. Another common error is classifying disinfectants or sanitizers under 3402, even if they have cleaning properties. Disinfectants primarily intended to kill germs fall under 3808. Additionally, complex chemical mixtures that are not primarily surface-active, washing, or cleaning preparations, but perhaps act as binders or processing aids, might mistakenly be placed here instead of 3824 (prepared binders, chemical products not elsewhere specified). The key is the 'surface-active, washing, or cleaning' function.

In 2025, the top exporters of HS code 3402 in UN Comtrade data were China ($4.9B, 12% of world exports), Germany ($4.9B) and the United States ($3.9B). World exports came to about $41.9B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

In 2025, the top importers of HS code 3402 in UN Comtrade data were Germany ($3.5B, 8.1% of world imports), France ($2.4B) and the United States ($2.2B). World imports came to about $42.6B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

HS code 3402 is a 4-digit heading under Chapter 34 of the Harmonized System. The first 2 digits (34) identify the chapter, and digits 3-4 (02) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
