🚗 Lead-Based Fuel Anti-Knock Agent (Ethyl Fluid)
🌐 HS Code Classification & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Strategy
📌 I. Product Definition & Classification: What is "Lead-Based Fuel Anti-Knock Agent"?
Lead-based anti-knock agents (commonly known as Ethyl Fluid) are chemical additives used in gasoline to increase the octane rating and prevent engine "knocking" or pinging during combustion.
In international trade, these products are NOT classified as raw lead or simple lead alloys. Instead, they are classified as chemical preparations and mixtures containing lead compounds (such as Tetraethyl lead or Tetramethyl lead).
⚠️ Critical Distinction:
- If the product is pure refined lead with additives specifically for anti-knock purposes → It may fall under Chapter 78 (Lead and Articles Thereof).
- If the product is a chemical mixture/preparation where lead compounds are the active ingredient for anti-knock functionality → It falls under Chapter 38 (Miscellaneous Chemical Products).
- Most commercial "Anti-Knock Agents" are chemical preparations and should be classified under 3811 or 3824, NOT raw lead codes.
📦 II. HS Code Classification Details (2026 Latest Tariff Matrix)
Based on the provided data, here are the applicable HS Codes for Lead-Based Anti-Knock Agents and related lead materials:
| HS Code | Product Description | Key Characteristics | Primary Use |
|---|---|---|---|
| 3811.11.50.00 | Lead-based anti-knock agent, based on lead compounds | Chemical preparation; active ingredient is lead compound | Added to gasoline to prevent knocking |
| 3811.11.10.00 | Lead-based anti-knock agent, based on lead compounds | Similar to above; specific sub-category under 3811.11 | Same as above |
| 7801.10.00.00 | Refined lead containing gasoline anti-knock agents | Refined lead (metallic state); unformed shape | Industrial lead metal with anti-knock additive |
| 7801.99.90.30 | Refined lead, lead alloy category, containing additives | Lead alloy; contains anti-knock additives | Structural/industrial lead products |
| 3824.84.00.00 | Lead-containing anti-explosion/delayed-release agent | Chemical preparation; broader "anti-explosion" category | Industrial chemical mixtures |
🔍 Key Insight:
- If you are importing a liquid or powder additive to be mixed into fuel → Use 3811.11.xxxxx or 3824.84.00.00.
- If you are importing solid lead ingots or metal that already contain anti-knock agents → Use 7801.10.00.00 or 7801.99.90.30.
- Misclassification Risk: Declaring a chemical anti-knock agent as "Lead Metal" (7801) will likely result in rejection, as it does not fit the definition of metallic lead.

| Document | Required | Notes |
|---|---|---|
| ✅ Safety Data Sheet (SDS) | ✔️ | Must confirm chemical composition and lead content. |
| ✅ Product Specification Sheet | ✔️ | Clearly state: "Lead-based anti-knock agent for gasoline" or "Refined lead alloy." |
| ✅ Formula/Composition Analysis | ✔️ | Critical for distinguishing between 3811 (chemical prep) and 7801 (metal). |
| ✅ Commercial Invoice | ✔️ | Must specify HS Code, CIF value, and country of origin. |
| ✅ Certificate of Origin (CO) | ✔️ | For verifying Chinese origin and applying correct tariffs. |
| ✅ Lead Content Declaration | ✔️ | Required for 7801 codes to calculate base tax on lead value. |
| ✅ Import License (if applicable) | ✔️ | Some lead-containing chemicals may require EPA or other regulatory approvals. |
✅ 2. Declaration Tips (Key Rules)
🔥 "Chemical Prep vs. Metal: Choose Wisely!"
| Scenario | Correct HS Code | Incorrect HS Code | Consequence |
|---|---|---|---|
| Liquid/Powder additive for fuel | 3811.11.xxxxx or 3824.84.00.00 |
7801.xxxxx |
Rejection, penalty, higher tax |
| Solid lead ingots with additives | 7801.10.00.00 or 7801.99.90.30 |
3811.11.xxxxx |
Misclassification, audit risk |
| General chemical mixture | 3824.84.00.00 |
3811.11.xxxxx |
Slightly higher tax (41.5% vs 35%) |
📌 Golden Rule:
- If it’s a chemical reaction mixture designed to boost octane → 3811.
- If it’s metallic lead with additives → 7801.
- Never declare chemical anti-knock agents as "Lead Metal" to avoid Section 301 tariffs.
✅ 3. Special Cases
| Case | Handling Advice |
|---|---|
| Lead Content in 7801 Codes | You must provide a breakdown of lead content value to calculate the 2.5% base tax correctly. |
| EPA Regulatory Compliance | Lead-based fuels are restricted in many jurisdictions. Ensure the product is for export-only or meets EPA exemptions for off-road/industrial use. |
| 122 Clause Application | The 10% tariff is mandatory for Chinese-origin goods under this clause. No exemptions available. |
| Section 301 Exclusions | Check if your specific product has been excluded from Section 301 tariffs. Most lead chemicals are not excluded. |

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
