🧪 Alkyl Naphthalene Intermediate (ANI)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition & Classification: What Exactly is "Alkyl Naphthalene Intermediate"?
Alkyl Naphthalene Intermediates (ANI) are critical chemical building blocks used primarily in the synthesis of Superplasticizers (for concrete), Polyalphaolefins (PAO) base oils, and various Detergents/Additives.
In international trade, classification hinges on the degree of alkylation and the specific chemical nature:
1. Technical Alkyl Naphthalene Sulfonate (TANS) / Sulfonated ANI:
Often classified under sulfonated organic products if highly sulfonated.
2. Unsubstituted/Alkylated Naphthalene Hydrocarbons:
Classified under Naphthalene derivatives in Chapter 29.
3. Mixtures/Preparations:
If mixed with solvents or other agents, they may fall under Chapter 38.
⚠️ Key Distinction Point:
- If the product is a pure chemical compound (e.g., Methyl Naphthalene, Ethyl Naphthalene, or technical grade Alkyl Naphthalene) → Chapter 29.
- If it is a sulfonated salt (e.g., Sodium Methyl Naphthalene Sulfonate) → Chapter 29 (specifically 2904).
- If it is a mixture with undefined composition or prepared as a final formulation → Chapter 38.
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Application Scenario | Chemical Nature |
|---|---|---|---|
2904.10.00.00 |
Alkylated, arylated, or unsubstituted naphthalenes; alkylated or arylated homologues of naphthalenes | Technical grade ANI for concrete superplasticizers; precursor for PAO | ✅ Pure Hydrocarbon |
2904.90.00.00 |
Other sulfonated naphthalenes and their salts; other esterified derivatives | Sulfonated ANI (e.g., for detergents, asphalt emulsifiers) | ✅ Sulfonated |
2902.90.00.00 |
Other aromatic hydrocarbons (if classified as naphthalene derivatives incorrectly) | Misclassification risk; strict scrutiny required | ❌ Risky |
3824.99.92.00 |
Other prepared binders for foundry molds/cores; other chemical products and preparations | If ANI is mixed with solvents or additives for specific use | ✅ Mixture |
🔍 Critical Reminder:
- Chapter 29 applies to isolated organic compounds. Most "ANI intermediates" used in industry are pure or near-pure 2904.10.00.00 (alkylated naphthalenes).
- If the product is sulfonated (e.g., Sodium Methyl Naphthalene Sulfonate), it falls under 2904.90.00.00.
- Do not misclassify as generic "chemical mixtures" (Chapter 38) unless it is explicitly a formulated product, as this attracts higher duties and stricter environmental reviews.

🛠️ IV. Customs Clearance Practical Advice (Real-World Pitfall Guide)
✅ 1. Required Documentation Checklist (All Mandatory)
| Document | Must Provide | Description |
|---|---|---|
| ✅ Safety Data Sheet (SDS) | ✔️ | Must comply with GHS; clearly state chemical identity (e.g., "Technical Alkyl Naphthalene"). |
| ✅ Certificate of Analysis (COA) | ✔️ | Specifies purity, alkylation degree, and impurity levels to prove it's not a mixture. |
| ✅ Product Photo & Label | ✔️ | Clear view of drum/barrel labeling, UN number (if hazardous), and batch number. |
| ✅ Commercial Invoice | ✔️ | Must explicitly state: "Alkylated Naphthalene, HS 2904.10.00.00". Avoid vague terms like "Chemical". |
| ✅ Non-Dangerous Goods Certificate | ✔️ | If applicable, to expedite customs inspection (ANI is often non-HAZMAT, but verify). |
| ✅ Fumigation Certificate | ✔️ | If shipped in wooden packaging. |
✅ 2. Declaration Tips (Critical Mnemonic)
🔥 "Pure Chemical, Code 2904; Mixture Goes to 38! Label Clearly, Avoid 35% Penalty!"
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| Technical Grade ANI (Pure) | 2904.10.00.00 |
Misdeclaring as "Surfactant" (3824) → Higher scrutiny |
| Sulfonated ANI Salt | 2904.90.00.00 |
Misdeclaring as "Soap" (3401) → Major error |
| ANI + Solvent Mixture | 3824.99.92.00 |
Misdeclaring as pure chemical → Duty evasion risk |
| Raw Naphthalene (Unalkylated) | 2902.11.00.00 |
Misdeclaring as alkylated → Wrong HS Code |
✅ 3. Special Case Handling
| Scenario | Handling Advice |
|---|---|
| OEM Private Label | Provide customer PO and specs; avoid generic "ANI" if custom blends exist. |
| Hazardous Classification | ANI is often classified as UN3077 (Environmentally hazardous substance, solid, n.o.s.) or non-hazardous. Verify with SDS to avoid unnecessary HAZMAT fees. |
| Transshipment from Vietnam/Malaysia | If re-exported, ensure Rules of Origin are met to claim IEEPA Exemption. Direct CN origin triggers 35%. |
| Used Drums | Must provide cleaning certificate; reused chemical containers face stricter EPA/Customs checks. |

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
