What Is the HS Code for Anionic Organic Surfactants?
The HS code for anionic organic surfactants is primarily 3402.31.**
HS codes classify goods for international trade under the Harmonized System managed by the World Customs Organization (WCO).
Anionic surfactants fall under Chapter 34 for surface-active agents, washing preparations, and related products.
In 2025, this 6-digit code remains stable until the next WCO revision in 2027.
What Are Anionic Organic Surfactants? Key Examples
Anionic organic surfactants are compounds that lower surface tension in water for cleaning applications.**
They carry a negative charge and excel in removing dirt and oils.
- Sodium lauryl sulfate (SLS): Common in shampoos and soaps.
- Sodium laureth sulfate (SLES): Foaming agent in personal care products.
- Linear alkylbenzene sulfonates (LAS): Used in laundry detergents.
- Alkyl sulfates: Industrial cleaning formulations.
- Soap salts: Traditional anionic types from fatty acids.
The global market exceeds $50 billion in 2025, driven by detergents and cosmetics.
2025 HS Code Table for Anionic Surfactants Classification
Use this table for quick HS code lookup for anionic surfactants in 2025.**
| HS Code | Description | Common Uses | 2025 Duty Notes |
|---|
| 3402.11 | Organic surface-active agents (cationic) | Conditioners | Not anionic |
| 3402.31 | Linear alkylbenzene sulphonic acids, salts thereof | Detergents, cleaners | Primary anionic code |
| 3402.39 | Other anionic surfactants | SLS, SLES mixtures | Verify structure |
| 3402.90 | Surface-active preparations | Blends, formulations | Mixtures only |
| 3401.20 | Soap in forms other than bars | Liquid soaps | Soap-based anionics |

Regional HS Code Changes for Surfactants in 2025
2025 introduces regional HS code extensions impacting anionic surfactant imports.**
No global WCO changes until 2027, but national updates are critical.
- GCC countries (Saudi Arabia, UAE, etc.): Mandatory 12-digit HS codes from January 1, 2025.
- US: HTS mandatory for all shipments post-de minimis changes on August 29, 2025.
- EU: Combined Nomenclature (CN) 2025 refines subheadings for cleaner formulations.
- China: Updated tariff schedules with stricter chemical classifications.
- Australia: New environmental duties on certain surfactants.
Example: GCC shifts 3402.31 to 3402.31.00.XX for precise duty rates (+0.5% average).
How to Find the Correct HS Code for Anionic Surfactants (Step-by-Step)
This 5-step process ensures accurate HS classification for anionic surfactants in 2025.**
- Review product SDS: Identify if it's LAS, SLS, or other anionic type.
- Search WCO database: Use official tool at wcoomd.org for Chapter 34.
- Add country digits: Extend to 8-12 digits (e.g., US HTS 3402.31.5000).
- Request binding ruling: Submit to customs for official confirmation.
- Update shipping labels: Include full HS on invoices and declarations.
Pro tip: Test with small shipments to validate before scaling.
Common Misclassification Risks for Anionic Surfactants HS Code
Using the wrong HS code for anionic surfactants can lead to penalties up to 50% of shipment value.**
- Confusing anionics (3402.31) with nonionics (3402.90).
- Ignoring mixtures that shift to 3402.90.
- Missing regional extensions like GCC 12-digit codes.
- Outdated codes pre-2025 updates.
- Soap vs. synthetic surfactant errors (3401 vs. 3402).
Avoid delays: Double-check chemical composition annually.
