🧪 Alkylated Naphthalene Raw Material (Chemical Intermediate)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional通关 Strategy
📌 I. Product Definition: What is "Alkylated Naphthalene"?
Alkylated Naphthalene is a complex aromatic hydrocarbon derivative produced by adding alkyl groups (such as methyl, ethyl, or longer chains) to the naphthalene structure. In international trade, it is not a single standardized commodity but a category of chemical intermediates used in lubricants, plasticizers, heat transfer fluids, and dye intermediates.
Because its specific chemical structure and application vary, it falls under different HS Codes depending on whether it is classified as a pure chemical substance, a lubricant formulation, or a general chemical additive.
⚠️ Critical Distinction:
- If it is a pure or refined chemical compound primarily used as a raw material → It falls under Chapter 29 (Organic Chemicals).
- If it is blended with oil or used specifically as a lubricant agent → It may fall under Chapter 34 or 38 (Preparations).
📦 II. HS Code Classification Matrix (2026 Latest Tariff Authority)
| HS Code | Product Description | Classification Logic | Applicable Scenario |
|--------|--------------------------|--------------------------|
| 2902.90.20.00 | Alkylated Naphthalenes (Methyl Naphthalene Homologues) | Classified as Cyclic Hydrocarbons (Naphthalene Series). It fits the definition of "Other cyclic hydrocarbons." | Pure alkylated naphthalene, high purity, used as a chemical intermediate or solvent. |
| 2902.90.30.50 | Other Cyclic Hydrocarbons | Classified under Other Organic Chemicals. Logically linked to alkylbenzenes due to similar aromatic ring structure. | Industrial-grade alkylated naphthalene not specifically listed elsewhere in Chapter 29. |
| 3403.19.10.00 | Lubricating Preparations Containing Petroleum Oil | Classified as a Lubricant Preparation. Contains mineral oils derived from petroleum/asphalt. | Alkylated naphthalene formulated with base oils for use as lubricants, gear oils, or metalworking fluids. |
| 3824.40.10.00 | Chemical Additives (Aromatic Content) | Classified as a Chemical Industrial Product. Contains aromatic compounds used as additives. | Alkylated naphthalene used as an additive in plastics, resins, or other chemical mixes. |
| 3824.99.29.00 | Other Chemical Products (Residual Category) | Classified under Fallback for "Other Chemicals". Broad aromatic hydrocarbon property. | Alkylated naphthalene not fitting specific additive or lubricant definitions; general chemical use. |
🔍 Key Note:
- Chapter 29 codes (2902...) generally apply to pure chemicals.
- Chapter 38 codes (3824...) apply to mixtures or preparations where the chemical acts as an additive or component.
- Misclassification Risk: Declaring a lubricant blend as a pure chemical (2902) or vice versa can lead to customs audits, back-taxes, and penalties.
💰 III. 2026 Latest Tariff Rate Breakdown (Including Surcharges)
✅ Applicable Country: China (Export/Import Context based on US Surcharges)
✅ Origin: China (CN)
✅ Effective Date: Ongoing (Subject to US Trade Policy Updates)
🎯 1. 2902.90.20.00 & 2902.90.30.50 —— Pure Chemicals (Cyclic Hydrocarbons)
| Item | Detail |
|---|---|
| Base Tariff | 0.0% |
| Section 301 Surcharge | +25.0% (USITC) |
| 122 Clause Surcharge | +10.0% (Specific US Provision) |
| Total Effective Rate | 35.0% |
| Tax Calculation | CIF Value × 35% |
| De Minimis Exemption | ❌ Not Available (Subject to strict scrutiny) |
| Legal Basis | USITC: 2902.90.20.00 → Section 301 + 122 Clause |
📌 Explanation:
- The base rate is 0%, reflecting the basic MFN (Most Favored Nation) tariff for certain cyclic hydrocarbons.
- However, the US imposes significant political surcharges:
- 25% under Section 301 (Trade Act of 1974).
- 10% under the "122 Clause" (often related to specific bilateral trade measures).
- Total burden: 35%. This is a high-risk tariff for pure chemical exports to the US.
🎯 2. 3403.19.10.00 —— Lubricant Preparations
| Item | Detail |
|---|---|
| Base Tariff | 0.2% |
| Section 301 Surcharge | +25.0% |
| 122 Clause Surcharge | +10.0% |
| Total Effective Rate | 35.2% |
| Tax Calculation | CIF Value × 35.2% |
| De Minimis Exemption | ❌ Not Available |
| Legal Basis | USITC: 3403.19.10.00 → Section 301 + 122 Clause |
📌 Explanation:
- Slightly higher base rate (0.2%) due to being classified as a "preparation" rather than a pure substance.
- Surcharges remain identical to pure chemicals.
- Total burden: 35.2%.
🎯 3. 3824.40.10.00 & 3824.99.29.00 —— Chemical Additives / General Chemicals
| Item | Detail |
|---|---|
| Base Tariff | 6.5% |
| Section 301 Surcharge | +25.0% |
| 122 Clause Surcharge | +10.0% |
| Total Effective Rate | 41.5% |
| Tax Calculation | CIF Value × 41.5% |
| De Minimis Exemption | ❌ Not Available |
| Legal Basis | USITC: 3824.40.10.00 / 3824.99.29.00 → Section 301 + 122 Clause |
📌 Explanation:
- These codes have a higher base tariff (6.5%) because they are considered "other chemical products" or "additives."
- Total burden: 41.5%. This is the highest tariff category in the dataset.
- Warning: Misclassifying a pure chemical as a "general additive" to avoid lower base rates is illegal and triggers customs audits. The correct classification depends on the primary use and composition.
🛠️ IV. Customs Clearance Practical Advice (Real-World Pitfalls)
✅ 1. Documentation Checklist (Non-Negotiable)
| Document | Required | Purpose |
|---|---|---|
| ✅ Safety Data Sheet (SDS) | ✔️ | Must specify chemical composition, CAS numbers, and purity. Critical for distinguishing Chapter 29 vs. 38. |
| ✅ Certificate of Analysis (COA) | ✔️ | Proves if the product is a pure compound (Chapter 29) or a mixture (Chapter 38). |
| ✅ Formula/Composition Statement | ✔️ | Detail % of alkylated naphthalene vs. base oils or other additives. |
| ✅ Commercial Invoice | ✔️ | Must clearly state: "Alkylated Naphthalene, [Purity]%," not just "Chemical Raw Material." |
| ✅ Bill of Lading | ✔️ | Consistent with invoice; mark as "Dangerous Goods" if applicable (flammable liquid). |
✅ 2. Classification Strategy (Key Mantra)
🔥 "Pure is Ch.29, Blended is Ch.38, Use Dictates Code!"
| Scenario | Correct HS Code | Risk if Misclassified |
|---|---|---|
| High-purity Alkylated Naphthalene (e.g., >95%, used as solvent/reactant) | 2902.90.20.00 or 2902.90.30.50 |
If declared as 3824, you pay 6.5% more base tax unnecessarily. If declared as 3403, you risk false declaration. |
| Alkylated Naphthalene in Lubricant Oil (blended with mineral oil) | 3403.19.10.00 |
If declared as 2902, customs may reject it as not a pure chemical, leading to delays & re-inspection. |
| Additive for Plastics/Resins (mixed with other stabilizers) | 3824.40.10.00 or 3824.99.29.00 |
High base rate (6.5%). Ensure you have proof of it being a commercial preparation, not a bulk chemical. |
✅ 3. Special Handling Tips
| Situation | Recommendation |
|---|---|
| Mixed Shipments | If the shipment contains both pure chemicals and lubricants, they must be declared separately. Do not mix HS Codes in one line item. |
| Customs Audit Trigger | High volume of 2902 declarations from China often triggers anti-dumping or countervailing duty reviews. Keep production records ready. |
| "122 Clause" Compliance | Ensure your export license and end-user certificate (if required) are up-to-date, as the 10% surcharge is politically sensitive. |
🌍 V. Global Market Comparison (2026 Update)

📌 Conclusion:
- The US market is the most expensive due to geopolitical surcharges.
- EU and other markets offer significantly lower tariffs for the same goods.
- Cost Optimization: Consider supply chain diversification if exporting to the US is too costly.
📌 VI. Common Errors & Pitfalls (Lessons Learned)
❌ Error 1: Declaring all Alkylated Naphthalene under one HS Code (2902.90.20.00) regardless of purity.
👉 Consequence: Customs rejects the entry if the product is a lubricant blend, forcing a re-classification and potential penalties.
❌ Error 2: Ignoring the 122 Clause (10% surcharge).
👉 Consequence: Underpayment of duties leads to accrued interest and fines upon audit.
❌ Error 3: Using vague descriptions like "Chemical Liquid" on the Invoice.
👉 Consequence: Customs may assign their own HS Code (often the highest one, e.g., 3824.99.29.00) and detain the shipment for investigation.
✅ Correct Practice:
"Alkylated Naphthalene, 98% Purity, CAS No. XXXXX-XX-X, for use as Chemical Intermediate. Pure Substance, Not Blended."
🎯 VII. Final Recommendation: Professional Declaration Saves Money!
🎯 Remember This Mantra:
🔹 "Pure is 2902, Blended is 3403/3824; Surcharge is 35-41%, Don't Ignore the Clause!"
🔹 "SDS and COA are your best friends; Vague descriptions are your worst enemy!"
📌 Pro Tip:
If you are exporting pure Alkylated Naphthalene to the US, consider applying for a HTS Exclusion under Section 301 if available, or explore transshipment through a third country (note: illegal transshipment carries severe risks). Always engage a licensed customs broker to verify the Chapter 29 vs. 38 classification based on your specific formula.

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
