🧪 Industrial Chemicals: Lead-Containing Anti-Explosion Agents & High-Efficiency Dispersants
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 1. Product Definition & Classification: What Exactly Are These "Special" Chemicals?
These products belong to the broad category of "Other chemical products" but contain specific hazardous or restricted ingredients (Lead and specific organic compounds). In international trade, they are not classified under standard pesticides or simple additives because of their specialized industrial function (anti-explosion/dispersant) and composition.
Key Distinction: * Pesticide Classification (3808/3824.84/3824.85): If the product is primarily used to kill pests or contains listed persistent organic pollutants (POPs) like Aldrin, DDT, or Lindane, it falls under specific restricted subheadings. * Specialty Chemical Classification (3808/3811): If the product is an industrial additive (e.g., for metal casting, explosives manufacturing, or industrial processing) containing Lead or specific dispersants, it is classified as a "chemical product not elsewhere specified or included."
⚠️ Critical Classification Point:
- If the product contains listed POPs (Aldrin, Chlordane, DDT, Dieldrin, Endrin, Heptachlor, Mirex, Toxaphene) → It is classified under 3824.84.00.00.
- If the product contains 1,2,3,4,5,6-Hexachlorocyclohexane (HCH), including Lindane → It is classified under 3824.85.00.00.
- If the product is a Lead-containing anti-explosion agent or high-efficiency dispersant (NOT primarily a pesticide):
- If it fits the specific description of "Anti-explosion agents" → Potentially 3808.94.90.
- If it is a general industrial dispersant/additive → Potentially 3811.90.90.
📦 2. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Applicable Scenario | Key Ingredient/Feature |
|---|---|---|---|
3824.84.00.00 |
Prepared binders for foundry molds; Chemical products containing specific POPs | Industrial binders or chemicals containing Aldrin, Camphechlor, Chlordane, Chlordecone, DDT, Dieldrin, Endosulfan, Endrin, Heptachlor, or Mirex | ❌ Highly Restricted (POPs) |
3824.85.00.00 |
Chemical products containing 1,2,3,4,5,6-Hexachlorocyclohexane (HCH), including Lindane | Specialized industrial chemicals or pesticides containing HCH/Lindane | ❌ Highly Restricted (POPs) |
3808.94.90 |
Other chemical products not elsewhere specified, containing Lead, used as anti-explosion agents and high-efficiency dispersants | Industrial explosives manufacturing or lead-based anti-detonation additives | ⚠️ Error Retrieval (See Tax Note) |
3811.90.90 |
Other chemical products not elsewhere specified, used as dispersants and additives in industrial applications, including lead-containing formulations | General industrial dispersants, anti-static agents, or additive blends containing lead | ⚠️ Error Retrieval (See Tax Note) |
🔍 Key Reminder:
- 3824.84 and 3824.85 are for products containing specific banned/restricted organic pollutants.
- 3808.94.90 and 3811.90.90 are for Lead-containing industrial chemicals that are NOT the specific POPs listed in 3824.84/85.
- Do not misclassify Lead-based industrial chemicals as Pesticides (3808.90) if they are explicitly for anti-explosion/dispersant purposes, as this may lead to incorrect duty assessment or regulatory rejection.

🛠️ 4. Customs Clearance Practical Advice (Pitfall Avoidance Guide)
✅ 1. Preparation Checklist (Non-Negotiable)
| Document | Mandatory? | Explanation |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must clearly state chemical composition, percentages of lead/POPs, and intended industrial use (anti-explosion/dispersant). |
| ✅ Safety Data Sheet (SDS) | ✔️ | Required by OSHA and Customs to verify hazardous material classification. |
| ✅ Certificate of Analysis (COA) | ✔️ | To prove exact chemical content, especially to distinguish between POPs (3824.84/85) and general Lead compounds (3808/3811). |
| ✅ EPA TSCA Certification | ✔️ | For chemicals under the Toxic Substances Control Act. Mandatory for import. |
| ✅ Commercial Invoice | ✔️ | Must explicitly describe the product as "Lead-containing industrial dispersant" or "Anti-explosion agent," NOT generic "Chemical." |
| ✅ Import License/Permit | ✔️ | Critical for products under 3824.84/85 (POPs) or if lead content exceeds certain thresholds. |
✅ 2. Declaration Tips (Key Mantra)
🔥 “Accurate Description, SDS Attached, EPA Certified, POPs Verified!”
| Situation | Correct Declaration | Wrong Practice |
|---|---|---|
| Product contains DDT, Chlordane, etc. | Declare as 3824.84.00.00 with POPs disclosure |
Misdeclare as 3824.99.00.00 → Penalty + Confiscation |
| Product contains Lindane/HCH | Declare as 3824.85.00.00 |
Misdeclare as general chemical → Regulatory Violation |
| Product is Lead-based anti-explosion agent | Declare as 3808.94.90 with SDS |
Misdeclare as 3808.90.00.00 (Pesticide) → Wrong Duty/Regulation |
| Product is General Lead Dispersant | Declare as 3811.90.90 |
Misdeclare as 3811.10.00.00 (Detergents) → Misclassification |
✅ 3. Special Handling for Restricted Substances
| Substance | Regulation | Clearance Impact |
|---|---|---|
| Aldrin, DDT, Chlordane, etc. (3824.84) | EPA TSCA / Stockholm Convention | High Risk. Import may be prohibited or require specific EPA approval. Even if tax is 0%, customs may reject shipment without EPA clearance. |
| Lindane/HCH (3824.85) | EPA / FDA | High Risk. Similar to above. Verify if product is for industrial use only (allowed) or consumer use (banned). |
| Lead Compounds (3808/3811) | EPA / OSHA | Moderate Risk. Must provide SDS. Ensure lead content is within industrial limits. No specific import ban, but heavy regulation. |
🌍 5. Global Market Clearance Comparison (2026 Latest)

| 🇨🇳 China | 3824.84/85 or 3808/3811 |
Varies | CCC (if applicable), MSDS | Check local MEP regulations for POPs. |
| 🇪🇺 EU | 3824.99 or 3811 |
0% - 4.7% | REACH Registration | REACH compliance is mandatory. POPs are banned in EU. |
| 🇬🇧 UK | 3824.99 or 3811 |
0% - 4.7% | UK REACH | Similar to EU, strict on POPs and Lead. |
📌 Conclusion:
- USA: 0% duty for POP-containing chemicals in these specific codes, but regulatory barriers are extremely high.
- EU/UK: Lead and POPs are heavily restricted under REACH. Import may be prohibited unless specifically exempted.
- Always verify EPA/REACH compliance before shipping. Tax is not the only barrier.
📌 6. Common Mistakes & Pitfall Guide (Blood Lesson)
❌ Mistake 1: Declaring POP-containing chemicals (3824.84/85) as generic "Chemical Products" (3824.99.00.00)
👉 Consequence: Customs audit reveals exact composition → Heavy fines, shipment seizure, and EPA penalties.
❌ Mistake 2: Ignoring EPA TSCA certification for Lead-based or POP-containing chemicals
👉 Consequence: Customs hold at port until EPA review, which can take weeks/months → Demurrage costs + Delay.
❌ Mistake 3: Misclassifying Lead-based industrial dispersants as Pesticides (3808.90.00.00)
👉 Consequence: Incorrect duty rate + Regulatory mismatch → Compliance violation.
❌ Mistake 4: Assuming 0% tax means "No Restrictions" for 3824.84/85
👉 Consequence: Shipment rejected by Customs/EPA → Return or Destruction at exporter's cost.
✅ Correct Approach:
"Industrial Lead-Containing Anti-Explosion Agent, CAS Number [XXX], SDS Attached, EPA TSCA Compliant, Intended for Industrial Use Only, Not for Consumer Application."
🎯 7. Conclusion: Precise Classification Saves Time, Money, and Shipment!
🎯 Remember the Mantra:
🔹 “POPs have 0% tax but 100% restriction. Lead chemicals need SDS and EPA. Don’t guess, verify!”
🔹 “HS Code is not just about tax, it’s about regulation. 3824.84/85 are trap codes!”
📌 Pro Tip:
If your product contains any of the listed POPs (Aldrin, DDT, Lindane, etc.), contact your US customs broker AND EPA liaison before shipping. Do not rely solely on 0% tariff rates. Regulatory compliance is the key to clearance.
📣 Immediate Action:
📞 Contact your Customs Broker + Provide SDS + Verify EPA TSCA Status
🚀 Ensure your Lead/POPs declaration is accurate to avoid port holds and penalties!
✨ Professional clearance starts with precise classification!
💼 Your chemical shipment’s success depends on regulatory accuracy, not just tax rates!

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
