🧪 Chromated Rosin Salt (Chromium-Treated Rosin Salts)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition & Classification: What exactly is "Chromated Rosin Salt"?
Chromated Rosin Salt is a specialized chemical preparation derived from natural resins (rosin) that have undergone chemical modification through treatment with chromium salts. It is primarily used for industrial or technical applications, such as:
- Corrosion Inhibitors: In water-based coatings, metal primers, and rust preventatives.
- Adhesives & Sealants: Enhancing bonding properties and heat resistance.
- Leather & Textile Processing: Used in tanning agents or finishing agents.
⚠️ Key Distinction Point:
- The term "Chromated" indicates a chemical modification (not just a physical mixture), pushing it towards chemical preparations. - "Rosin Salt" indicates it is derived from modified natural resins. - If used strictly as a chemical additive/preparation not elsewhere specified, it falls under Chapter 38. - If viewed as a processed derivative of fats/oils (rosin is a vegetable oil derivative), it could theoretically fall under Chapter 35, but this is less precise due to the chromium modification.
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Application Scenario | Precision Note |
|---|---|---|---|
382490 |
Chemical preparations and products, not elsewhere specified or included (including chromated rosin salt as a modified natural resin preparation) | Industrial corrosion inhibitors, adhesives, technical additives | ✅ Preferred: Best fits "chemical preparation" due to chromium modification |
351190 |
Animal/vegetable fats and oils, processed products (if considered a derivative product) | Specific formulations where rosin salt is treated as a fat/oil derivative | ❌ Less Precise: "Chromated" modification makes this classification risky and less accurate |
🔍 Critical Reminder:
-382490is the recommended classification because the product is a chemical preparation resulting from a reaction (chromation) of natural resins.
-351190is an alternative but only if the primary function is considered a fat/oil derivative and the chromium component is incidental. However, given the explicit "chromated" label,382490is more accurate for customs purposes.
- Misclassification as351190may lead to disputes if the chromium content is significant for the product's function.

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) — Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) — More specific grouping within the chapter
- Subheading (6 digits) — Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) — 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 — The standard duty rate applied to WTO members
- General rate — Applied to countries without trade agreements
- Trade remedy duties — Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
