🔥 Rubber Flame Retardant Plasticizer
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Full Analysis | Professional-Level Clearance Strategy
📌 I. Product Definition and Classification: Do You Really Understand "Rubber Flame Retardant Plasticizer"?
Rubber Flame Retardant Plasticizer is a functional additive used in the rubber industry to improve flexibility while simultaneously enhancing fire resistance. In international trade, its classification is complex because it involves three key elements: Material (Synthetic Rubber/Additive), Function (Flame Retardancy/Plasticizing), and Form.
The classification logic in splits into two main categories: 1. Material-Based Classification (Chapters 35 & 40): If the product is viewed primarily as a synthetic rubber material or a rubber chemical additive. 2. Function-Based Classification (Chapter 38): If the product is viewed primarily as a chemical product with specific performance characteristics (like flame retardancy) or as a surface-active agent (defoaming).
⚠️ Key Distinction Point:
- If the product is a polymer-based synthetic rubber with flame-retardant properties → Chapter 40 or 35.
- If the product is a chemical additive/defoamer used in rubber processing → Chapter 38.
- "Plasticizer" vs. "Flame Retardant": If it acts as a defoamer or chemical compound in rubber processing, it may fall under 3812 (Rubber Processing Agents) or 3402 (Surface Active Agents).
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Application Scenario | Classification Logic |
|---|---|---|---|
4002.99.00.00 |
Flame Retardant Synthetic Rubber, Material: Synthetic Rubber, meets bottom-item category rules | General synthetic rubber with flame-retardant features, no specific subtype matches | ✅ Material: Synthetic Rubber (Chapter 40) |
4002.19.00.19 |
Flame Retardant Synthetic Rubber, Material: Synthetic Rubber, Flame Retardancy is a performance feature, classified as other functional products | Specialized functional synthetic rubber, not covered by specific subheadings | ✅ Performance: Flame Retardant (Chapter 40) |
3506.91.50.00 |
Flame Retardant Synthetic Rubber, Material: Synthetic Rubber, meets polymer or rubber category, no morphological conflict | Polymer-based flame retardants, treated as rubber/polymer additives | ✅ Material: Polymer/Rubber (Chapter 35) |
3812.10.50.00 |
Rubber Defoamer, Material: Rubber-related Additive, Use: Belongs to Rubber Auxiliary Category | Additives used in rubber processing to reduce foaming, acts as a rubber auxiliary | ✅ Function: Rubber Auxiliary (Chapter 38) |
3402.42.90.00 |
Rubber Defoamer, Material: Organic Chemical Components, Meets Non-Ionic Surfactant Category | Chemical defoaming agents, classified as non-ionic surface active agents | ✅ Function: Surfactant/Defoamer (Chapter 34) |
🔍 Key Reminders:
-4002.99.00.00&4002.19.00.19: These fall under Chapter 40 (Rubber and Articles Thereof). They are classified because the core material is synthetic rubber. The flame retardant property is treated as a feature of the rubber itself.
-3506.91.50.00: Falls under Chapter 35 (Albuminoidal Substances; Modified Starches; Glues; Enzymes). Here, the product is viewed as a polymer/rubber additive with no morphological conflict.
-3812.10.50.00: Falls under Chapter 38 (Miscellaneous Chemical Products). This is the most common classification for rubber processing additives (like defoamers or flame retardants) that are not the primary material but are used to improve the processing or performance of rubber.
-3402.42.90.00: Falls under Chapter 34 (Soap; Organic Surface-Active Agents; Washing Preparations; Lubricating Preparations). This is used if the product is chemically a non-ionic surfactant used as a defoamer.

📌 VI. Common Errors & Pitfall Guide (Lessons Learned from Blood and Tears)
❌ Error 1: Declaring "Rubber Defoamer" as "Synthetic Rubber"
👉 Consequence: Tariff drops from 40% to 35% → Savings achieved! But if wrongly declared, risk of audit.
❌ Error 2: Declaring "Synthetic Rubber" as "Defoamer"
👉 Consequence: Tariff rises from 35% to 40% → Extra Cost!
❌ Error 3: Not providing SDS for Chemical Products
👉 Consequence: Customs delay or return due to lack of chemical safety information.
❌ Error 4: Using "Plasticizer" as the only description
👉 Consequence: Ambiguous classification → Risk of being classified under the highest tariff (40%).
✅ Correct Practice:
"Flame Retardant Synthetic Rubber, CAS No. XXXXX, Used for Rubber Processing, Material: Synthetic Rubber, Function: Flame Retardancy + Plasticizing, Model: XYZ"
🎯 VII. Conclusion: Professional Declaration, Save Time, Save Money, Increase Efficiency!

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
