🧪 Rosin Defoamer (松香消泡剂)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Entry Strategy
📌 1. Product Definition & Classification: Do You Really Understand "Rosin Defoamers"?
Rosin defoamers are chemical additives used to eliminate unwanted foam in industrial processes involving rosin, turpentine, or resin-based formulations. In international trade, the classification depends entirely on the primary material composition and chemical form of the product.
The key distinction lies in whether the product is: 1. Solvent-based Rosin/Dextrin acids → Classified under Chapter 38. 2. Natural Resins/Oil Resins (less common for pure "defoamers" but possible in raw forms) → Classified under Chapter 13. 3. Distillation Products of Resins → Classified under Chapter 38.
⚠️ Critical Distinction Point: - If the product is primarily Rosin & Tall Oil Acids dissolved or mixed in a solvent medium: → 3806.10.00 - If the product is primarily Natural Resin or Oil Resin derivatives without being a chemical preparation: → 1301.90.40 or 1301.90.91 - If the product is a Distillation Product of rosin (e.g., tall oil, crude rosin solvents): → 3805.10.00
📦 2. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Application Scenario | Material Form |
|---|---|---|---|
3806.10.00.10 |
Rosin solvents; matches rosin & rosin acid material in chemical form | Chemical preparations containing rosin acids | ✅ Chemical Preparation |
3806.10.00.50 |
Rosin solvents; matches rosin & resin acid material in rosin derivative form | Derivatives of rosin used as solvents | ✅ Rosin Derivative |
1301.90.40.00 |
Rosin solvents; matches oil resins & derivatives from rosin source | Natural resins or oil resin extracts | ✅ Natural Resin/Extraction |
1301.90.91.90 |
Rosin solvents; matches natural resin material & catch-all category | General natural resins not specified elsewhere | ✅ Natural Resin (Catch-all) |
3805.10.00.00 |
Rosin solvents; matches resin/terpene derivatives &胶树脂蒸馏产物 (Gum resin distillation products) | Distillation products of rosin/tall oil | ✅ Distillation Product |
🔍 Key Reminder: - All products containing Rosin Acids as the main chemical component in a prepared form fall under 3806. - Products that are purely Natural Resins (unprocessed or minimally processed) fall under 1301. - Distillation by-products of rosin processing fall under 3805.

🛠️ 4. Customs Clearance Practical Advice (Pitfall Avoidance Guide)
✅ 1. Documentation Checklist (All Required)
| Document | Required | Explanation |
|---|---|---|
| ✅ Safety Data Sheet (SDS) | ✔️ | Must clearly state chemical composition (Rosin Acid vs. Natural Resin). |
| ✅ Certificate of Analysis (COA) | ✔️ | To prove if the product is a "Preparation" (Ch 38) or "Natural Resin" (Ch 13). |
| ✅ Product Technical Specification | ✔️ | Details on manufacturing process (Distilled vs. Chemical Solvent-based). |
| ✅ Commercial Invoice | ✔️ | Must describe product accurately: "Rosin Solvent" or "Natural Resin Extract". |
| ✅ Packing List | ✔️ | Weight, volume, and net/gross weight details. |
✅ 2. Declaration Strategy (Key Principles)
🔥 "Chemical = Ch 38 (40%), Natural = Ch 13 (17.5%-18.8%)"
| Scenario | Correct Declaration | Incorrect Action |
|---|---|---|
| Product is Rosin Acid in Solvent | 3806.10.00.10 or .50 |
Misdeclare as Natural Resin → High Risk of Penalty |
| Product is Oil Resin Extract | 1301.90.40.00 |
Misdeclare as Chemical Solvent → Overpay Taxes |
| Product is Crude Distillate | 3805.10.00.00 |
Misdeclare as Refined Chemical → Classification Error |
| Mixed Composition | Provide full formula | Vague description → Customs Hold |
✅ 3. Special Case Handling
| Case | Handling Advice |
|---|---|
| OEM Rosin Defoamer | Provide client’s formulation specs. If the client defines it as "Natural Resin," ensure your production process aligns. |
| High Chemical Content | If solvent >50% or chemical processing is evident, must use Ch 38 codes. |
| Low Processing (Raw) | If only extraction/distillation, consider Ch 13 or 3805 to reduce tax burden. |
| Third-Party Testing | Obtain a lab report proving the chemical structure to support Ch 13 classification if applicable. |
🌍 5. Global Main Market Clearance Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff | Certification | Notes |
|---|---|---|---|---|
| 🇺🇸 USA | 3806.10.00 |
40% (Ch 38) | EPA TSCA + SDS | High tariff due to 301/122. |
| 🇺🇸 USA | 1301.90.40 |
18.8% (Ch 13) | SDS | Lower tariff if natural resin. |
| 🇨🇳 China | 3806.10.00 |
5% | None | No retaliatory tariffs domestically. |
| 🇪🇺 EU | 3806.10 |
6.5% | REACH | No 301/122 surcharges. |
| 🇯🇵 Japan | 3806.10 |
5.0% | None | Standard MFN rates. |
📌 Conclusion: - USA imposes 40% on chemical rosin preparations (
3806) but only 18.8% on natural oil resins (1301.90.40). - Optimization Opportunity: If your product qualifies as an Oil Resin (1301.90.40.00), you can save ~21.2% in taxes compared to3806. - Risk: Misclassification between Ch 38 and Ch 13 is a common audit target.
📌 6. Common Mistakes & Pitfalls (Lessons Learned)
❌ Mistake 1: Declaring a chemical rosin solvent as Natural Resin (1301)
👉 Consequence: Customs rejects declaration, fines + back taxes. The chemical structure will not match a natural resin.
❌ Mistake 2: Declaring Crude Distillate as Prepared Chemical (3806)
👉 Consequence: Overpayment of taxes. 3805 (40%) and 3806 (40%) are similar, but if it’s a natural resin, 1301 is cheaper.
❌ Mistake 3: Vague Description "Defoamer" on Invoice
👉 Consequence: Customs cannot determine the primary material. Leads to delay and potential reclassification.
✅ Correct Approach:
"Rosin Acid Solvent (Chemical Preparation), Model XYZ, CAS No. [Insert CAS], SDS Attached"
OR
"Natural Oil Resin Extract, Derived from Pine, Model ABC, SDS Attached"
🎯 7. Conclusion: Precise Classification, Cost Reduction!
🎯 Remember the Key Principle:
🔹 "Chemical Preparation = Ch 38 (40%)"
🔹 "Natural Resin/Oil Resin = Ch 13 (17.5%-18.8%)"
🔹 "Distillation By-product = Ch 38 (40%)"🔹 "The difference is 21.2%! Declaration accuracy saves money!"
📌 Tips:
- If your product is natural or minimally processed, strive for 1301.90.40.00 or 1301.90.91.90.
- If it is chemically prepared, prepare for 3806.10.00 at 40%.
- Always provide SDS and COA to support your classification.
- Consider applying for an Advance Ruling from US Customs to mitigate risk.

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
