π§ͺ Leather Auxiliary Dispersant (Chemical Additive for Tanning Industry)
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Classification | Professional Compliance Strategy
π I. Product Definition & Classification: What is "Leather Auxiliary Dispersant"?
A Leather Auxiliary Dispersant is a chemical additive used in the leather tanning and finishing processes. It functions as a dispersing agent, wetting agent, leveling agent, or emulsifier to ensure uniform distribution of dyes, fats, tanning agents, or other chemicals across the leather surface.
In international trade, it is typically classified under chemical organic compounds or prepared additives for industrial processes, depending on its primary function and composition.
β οΈ Key Distinction:
- If the product is primarily a surfactant/emulsifier β Often classified under 3402 (Organic surface-active agents).
- If it is a polymeric dispersant β May fall under 3906 or 3907.
- If it is a premixed chemical preparation for leather treatment β Could be 3824 (Prepared binders, prepared additives, etc.).
π¦ II. HS Code Classification Details (2026 Official Tariff Schedule)
| HS Code | Product Description | Application Scenario | Primary Function |
|---|---|---|---|
3402.90.91.00 |
Organic surface-active agents and preparations (other than soap), for industrial use, not containing petroleum oils | Leather dyeing, fatliquoring, leveling | β Dispersing/Wetting |
3824.99.92.00 |
Prepared additives for industrial processes (e.g., binders, dispersants, stabilizers), not specified elsewhere | Leather tanning auxiliaries | β Prepared Chemical |
3906.90.90.00 |
Acrylic polymers in primary forms (e.g., polyacrylate dispersants) | Synthetic leather finishing | β Polymer-based |
3907.90.90.00 |
Other polyacetals, polyformaldehydes, etc. | Specialty leather coatings | β Polymer-based |
3809.93.00.00 |

π Priority Recommendation:
-3402.90.91.00is the most common classification for surfactant-based dispersants used in leather processing.
-3824.99.92.00is used for complex chemical preparations that are not primarily surfactants but include dispersing agents.

About HS Code Classification
The Harmonized System (HS) is an internationally standardized nomenclature developed by the World Customs Organization (WCO) to classify traded products. Over 200 countries use the HS system as the basis for customs tariffs, trade statistics, and import/export regulations.
Each HS code follows a hierarchical structure:
- Chapter (2 digits) β Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) β More specific grouping within the chapter
- Subheading (6 digits) β Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) β Country-specific extensions for further classification, such as US HTSUS 10-digit codes
Correct HS code classification is essential for smooth customs clearance, accurate duty payment, and compliance with trade regulations. Misclassification can lead to customs delays, overpayment of duties, or penalties.
When importing from CN to US, the applicable tariff rates may include:
- Most-Favored-Nation (MFN) rate β The standard duty rate applied to WTO members
- General rate β Applied to countries without trade agreements
- Trade remedy duties β Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
