U.S. exports of other organic surface-active agents (amphoteric and remaining types) (HS 340249) totaled $5.9M in July 2026.
Importers of Other Organic Surface-Active Agents (Amphoteric and Remaining Types) paid $209K in duties in July 2026 — an effective duty rate of 14% on $1.5M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataAmphoteric surfactants and any organic surface-active agents not captured by the anionic, cationic, or nonionic headings are classified under heading 340249, split between aromatic/modified-aromatic types (3402491000) and non-aromatic types (3402499000). Betaines, imidazoline-based amphoterics, and amine oxides — widely used in mild personal-care cleansers and industrial formulations for their low irritation profiles — are the primary trade items here. Because this heading functions as a catch-all for novel or hybrid surfactant chemistries, importers of new-to-market surfactant actives should consider requesting a CBP binding ruling to confirm classification before large-scale importation.

Cocamidopropyl betaine is an amphoteric surfactant that does not carry a permanent charge and is not anionic, cationic, or nonionic in the strict sense. It is generally classified under heading 340249 — specifically 3402499000 as a non-aromatic organic surface-active agent NESOI. Because CAPB is derived from coconut oil and has a modified amide structure, confirming its aromatic or non-aromatic character via a technical data sheet is important for line selection.
Heading 340249 covers the active surfactant compound itself — even if diluted in water or a carrier — when it is not blended with builders, chelating agents, fragrances, or other functional additives that would make it a 'preparation.' Once the product is a formulated mixture designed for a specific cleaning or washing application, it transitions to heading 3402.50 (retail) or 3402.90 (non-retail) as a preparation. The degree of formulation and the presence of non-surfactant functional ingredients are the key classification factors.
