🧪 Aromatic Amine Rubber Accelerators
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Compliance Strategy
📌 I. Product Definition & Classification: What Are "Aromatic Amine Rubber Accelerators"?
Aromatic Amine Rubber Accelerators are specialized chemical additives used in the rubber manufacturing industry. Their primary function is to speed up the vulcanization process (the chemical reaction that transforms rubber from a sticky, unusable state into durable, elastic rubber).
In international trade, these chemicals are classified based on their chemical composition (aromatic amines) and their industrial application (rubber processing). Depending on the specific regulatory framework and the degree of "preparation" or "mixing," they may fall into different HS Code categories.
⚠️ Critical Distinction:
- Pure Chemical Compounds (Single substance, high purity) → Often classified under Chapter 29 (Organic Chemicals).
- Prepared Mixtures/Additives (Commercial products, blends, or preparations for specific industrial use) → Often classified under Chapter 38 (Miscellaneous Chemical Products).
- Foundry Binders → If the product is mistakenly identified or specifically formulated for mold binding rather than rubber vulcanization, it may fall under Chapter 38, Heading 3824.
📦 II. HS Code Classification Details (Based on Provided Data)
The provided data contains four potential HS Codes for this product. Below is a detailed breakdown of why each code might apply, based on the descriptions and tax structures provided in <DATA>.
| HS Code | Product Description & Classification Logic | Tax Rate (Total) | Tax Detail |
|---|---|---|---|
| 2928.00.00 | Aromatic Amine Rubber Accelerators • Why? This code directly matches the chemical description: "Aromatic amine rubber accelerators... classified under organic compounds containing nitrogen, specifically aromatic amines, used in rubber processing." • Best For: Pure, single-substance aromatic amines used strictly as accelerators. |
Error | Failed to retrieve tax information |
| 3811.90.00 | Other Chemical Products, Not Elsewhere Specified • Why? This code covers "Other chemical products, including rubber accelerators... such as aromatic amine types... falling under miscellaneous chemical preparations." • Best For: Commercially prepared blends, mixtures, or formulations of accelerators that do not fit the pure chemical definition of Chapter 29. |
Error | Failed to retrieve tax information |
| 3824.40.10.00 | Prepared Additives for Cements, Mortars, or Concretes • Why? The description states: "Prepared binders for foundry molds or cores... Containing 5 percent or more by weight of one or more aromatic or modified aromatic substances." • Caution: This code is for foundry/cement additives, NOT rubber accelerators. However, if the product is mislabeled or if a specific aromatic binder is used in foundry molds (often confused in industrial settings), it may be incorrectly or accidentally classified here. • Tax Implication: High tariff burden due to aromatic content. |
31.5% | Base: 6.5% + Additional: 25.0% |
| 3824.99.11.00 | Cultured Crystals (Ingots) • Why? The description mentions: "Cultured crystals (other than optical elements... weighing not less than 2.5 g each: In the form of ingots." • Caution: This seems unrelated to rubber accelerators. It may be a data error or a specific edge case where aromatic amine crystals are classified as "cultured crystals" for non-optical industrial use. Highly unlikely for standard rubber accelerators. |
25.0% | Base: 0.0% + Additional: 25.0% |
🔍 Key Insight:
- Codes 2928.00.00 and 3811.90.00 are the most likely correct classifications for standard aromatic amine rubber accelerators. However, tax information is not available in the provided data.
- Codes 3824.40.10.00 and 3824.99.11.00 carry high tariffs and appear to be misclassifications or edge cases. Importers must avoid these unless the product is explicitly a foundry binder or cultured crystal.

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
