🧪 SBR Solution for Adhesive Applications (Styrene-Butadiene Rubber)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 1. Product Definition & Classification: What Exactly is "SBR Solution"?
SBR Solution for Adhesive Applications refers to Styrene-Butadiene Rubber produced via solution polymerization, specifically formulated or designated for use in adhesives. In international trade, this material sits at a crossroads between raw rubber materials and prepared adhesives.
The classification depends heavily on whether the product is declared as: 1. Raw Material (Unprepared Rubber): The SBR latex or solid rubber concentrate before final adhesive formulation. 2. Prepared Adhesive: The SBR already mixed with solvents, resins, or additives to form a ready-to-use adhesive or a specific adhesive base.
⚠️ Key Distinction Point:
- If it is pure SBR rubber (latex or solid) intended for adhesive manufacturing → It is a Rubber Product (Chapter 40).
- If it is SBR mixed with solvents/additives to be used as an adhesive → It is a Prepared Adhesive (Chapter 35).
📦 2. HS Code Classification Details (2026 Latest Tariff Authority对照)
Based on the provided data, there are four primary HS Codes applicable, split between Raw Rubber and Prepared Adhesives.
| HS Code | Product Description | Category | Tax Rate | Basis for Classification |
|---|---|---|---|---|
4002.19.00.16 |
Solution Polymerized SBR for Adhesive Use | Raw Rubber | 35.0% | Material is Styrene-Butadiene Rubber. Form is solution-polymerized. Used for adhesives but classified as the raw polymer material. |
3913.90.10.00 |
SBR (Chemical Derivative of Natural Rubber) for Adhesive Use | Raw Rubber | 35.0% | Material is SBR. Form is solution-method. Classified under chemical derivatives of natural rubber for adhesive applications. |
3506.91.50.00 |
Prepared Adhesive Containing SBR Solution | Prepared Adhesive | 37.1% | Material contains SBR but is defined as a "prepared adhesive" (mixture). Meets polymer/rubber requirements for adhesive formulation. |
3506.99.00.00 |
SBR Solution Used as Adhesive | Prepared Adhesive | 37.1% | Defined as "Other prepared adhesives." SBR solution is the base, but the product is functionally an adhesive. |
🔍 Critical Note:
- HS 4002/3913 (Raw Rubber): Lower tax rate (35%). Choose if you are importing the pure rubber polymer to manufacture adhesives later.
- HS 3506 (Prepared Adhesive): Higher tax rate (37.1%). Choose if you are importing a mixture that is already ready for adhesive use.
- Misclassification Risk: Declaring a pre-mixed adhesive as raw rubber (3506 vs 4002) can lead to audits and penalties.

🛠️ 4. Customs Clearance Practical Advice (Real-World Pitfall Guide)
✅ 1. Required Documentation Checklist (Non-Negotiable)
| Document | Must Provide | Explanation |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must clearly state: "Styrene-Butadiene Rubber, Solution Polymerized." Include % Solids, Solvent Type (if any). |
| ✅ Formula/Composition Report | ✔️ | Critical for distinguishing between Raw Rubber (Chapter 40/39) and Prepared Adhesive (Chapter 35). |
| ✅ MSDS (Material Safety Data Sheet) | ✔️ | Must list chemical composition. If solvents/resins are added, it leans toward Chapter 35. |
| ✅ Commercial Invoice | ✔️ | Description must match HS Code logic: e.g., "SBR Latex for Adhesive Manufacturing" vs. "SBR Adhesive Solution." |
| ✅ Certificate of Origin | ✔️ | To confirm China origin for surcharge application. |
| ✅ Production Process Description | ✔️ | Explain if the product is "Unprepared" or "Prepared." |
✅ 2. Declaration Strategy (Key Mantra)
🔥 "Raw Rubber = Chapter 40/39 (35%); Prepared Adhesive = Chapter 35 (37.1%)! Misclassification = Penalty!"
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| Importing pure SBR latex/solids to mix later | 4002.19.00.16 or 3913.90.10.00 |
Declaring as "Adhesive" → Higher tax |
| Importing SBR mixed with solvents for direct use | 3506.91.50.00 or 3506.99.00.00 |
Declaring as "Raw Rubber" → Audit risk |
| SBR in Solution (Solvent + Rubber) | Check Formula: If only solvent+rubber, may be Chapter 35. | Assuming all "solution" products are Chapter 40 |
✅ 3. Special Cases Handling
| Case | Handling Advice |
|---|---|
| OEM Custom Adhesive | Provide customer formula + design specs. Avoid generic "Adhesive" names; use specific chemical names. |
| SBR Latex vs. Solid Rubber | Latex is often 4002.19. Solid rubber may be 4002.51 or 3913.90. Confirm physical state. |
| Duty Drawback | If imported as Raw Rubber (35%) and later exported as finished goods, potential for duty drawback exists. |
| Section 301 Exemption | No general exemption for SBR from China. Check for specific UFLPA compliance if supply chain is complex. |
🌍 5. Global Market Comparison (2026 Latest)

📌 6. Common Errors & Pitfalls (Blood & Tears Lessons)
❌ Error 1: Declaring Prepared Adhesive as Raw Rubber
👉 Consequence: Customs may assess 37.1% instead of 35%, plus penalties for misclassification.
👉 Avoid: Provide a detailed formula showing if it is "prepared" or "unprepared."
❌ Error 2: Misidentifying Solution Polymerized SBR as Emulsion SBR
👉 Consequence: Different HS Code subheadings. Solution SBR is often 4002.19 or 3913.90. Emulsion is 4002.51.
👉 Avoid: Specify "Solution Polymerized" in the description.
❌ Error 3: Ignoring the 122 Clause
👉 Consequence: Failing to account for the 10% surcharge leads to budget miscalculations.
👉 Avoid: Always include 122 Clause in cost analysis for China-origin goods.
❌ Error 4: Vague Product Description ("SBR Rubber")
👉 Consequence: Customs detention for unclear classification.
👉 Avoid: Use precise terms: "Solution Polymerized Styrene-Butadiene Rubber, Latex Form."
✅ Correct Practice:
"SBR Solution Rubber, Solution Polymerized, Latex Form, For Adhesive Manufacturing, TSCA Compliant, HS: 4002.19.00.16"

关于 HS 编码归类
协调制度（HS）是由世界海关组织（WCO）制定的国际贸易商品分类标准。全球 200 多个国家采用 HS 系统作为海关关税、贸易统计和进出口监管的基础。
每个 HS 编码遵循以下层级结构：
- 章（2 位）——商品大类（例如：第 84 章：机器和机械设备）
- 品目（4 位）——章内的更具体分类
- 子目（6 位）——国际通用细分，所有 WCO 成员国统一使用
- 本国细分（8-10 位）——各国自行扩展的细分编码，如美国 HTSUS 10 位编码
正确的 HS 编码归类对于顺利通关、准确缴纳关税和遵守贸易法规至关重要。错误归类可能导致海关延误、多缴关税或罚款。
从CN进口到US时，适用的关税税率可能包括：
- 最惠国（MFN）税率——适用于 WTO 成员国的标准关税税率
- 普通税率——适用于无贸易协定国家
- 贸易救济关税——附加关税，如 301 条款（反倾销）、232 条款（国家安全）或反补贴税
