🧪 Carbon Tetrachloride Metabolism Research Reagent
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Strategy
📌 I. Product Definition & Classification: What is "Carbon Tetrachloride Metabolism Reagent"?
Carbon tetrachloride (CCl₄) metabolism research reagents are specialized chemical substances or kits used in laboratory settings or for diagnostic purposes. They typically contain Carbon Tetrachloride (CTC) as a core component, utilized for studying cellular responses, toxicology, or metabolic pathways.
In international trade, these products are classified into two distinct categories based on their primary function: 1. Laboratory/Diagnostic Kits: Containing CTC mixed with other biological or chemical buffers, packaged for specific analytical use. 2. Pure/Industrial Solvent: Bulk or refined CTC used primarily as a chemical solvent or raw material.
⚠️ Key Distinction Point:
- If the product is packaged as a "Kit" or "Reagent" intended for lab/diagnostic analysis (even if it contains CTC) → Classified under Chapter 38 (3822.19).
- If the product is Pure Carbon Tetrachloride used as a solvent or raw chemical → Classified under Chapter 29 (2903.19).
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Application Scenario | Tax Rate (Total) |
|---|---|---|---|
3822.19.00.40 |
Carbon Tetrachloride Cell Biology Reagent or Kit, containing CTC, for laboratory or diagnostic use | Lab research, toxicity testing, metabolic studies | 10.0% |
3822.19.00.10 |
Carbon Tetrachloride Cell Biology Reagent or Kit, containing CTC, for diagnostic or lab reagents | Diagnostic kits, analytical reagents | 10.0% |
2903.19.60.50 |
Carbon Tetrachloride Solvent, belonging to saturated chlorinated acyclic hydrocarbon derivatives, used as chemical solvent | Industrial solvent, raw chemical intermediate | 40.5% |
🔍 Critical Reminder:
- Reagents/Kits: Must be clearly described as "Reagent" or "Kit" and intended for lab/diagnostic use. If classified here, the tariff is significantly lower (10%).
- Pure Solvent: If the product is pure CTC or described primarily as a "Solvent" without lab/diagnostic context, it falls under Chapter 29, incurring a much higher tariff (40.5%).
- Misclassification Risk: Declaring a pure solvent as a "reagent kit" to save taxes can lead to customs audits, penalties, and delayed clearance.
💰 III. 2026 Latest Tariff Rate Details (Including Surtaxes & Policy Add-ons)
✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Date: November 10, 2025 (and subsequent imports)
🎯 1. 3822.19.00.40 & 3822.19.00.10 —— Laboratory/Diagnostic Reagents (Containing Carbon Tetrachloride)
| Item | Content |
|---|---|
| Base Tariff | 0.0% (ad valorem) |
| Section 301 Surcharge | 0.0% |
| Section 122 Tariff | +10.0% (Specific provision for certain lab chemicals) |
| Total Tariff | 10.0% |
| Tax Calculation | CIF Value × 10% |
| De Minimis Eligibility | ❌ No (Subject to stricter scrutiny for chemical imports) |
| Legal Basis Path | USITC:3822.19.00 → Section 122: 10% |
📌 Explanation:
- The 10% tariff is driven by Section 122 provisions, not the typical Section 301 (which is 0% for this subheading).
- This classification applies specifically to reagents/kits used for diagnostic or lab purposes.
- Advantage: Compared to pure chemical solvents, this is a 30.5% lower tax burden.
🎯 2. 2903.19.60.50 —— Pure Carbon Tetrachloride (Solvent/Raw Material)
| Item | Content |
|---|---|
| Base Tariff | 5.5% |
| Section 301 Surcharge | +25.0% (Standard China-specific surcharge) |
| Section 122 Tariff | +10.0% |
| Total Tariff | 40.5% |
| Tax Calculation | CIF Value × 40.5% |
| De Minimis Eligibility | ❌ No |
| Legal Basis Path | IEEPA:9903.01.25 → USITC:2903.19.60.50 → Section 122: 10% |
📌 Note:
- This tariff is significantly higher due to the combination of Base (5.5%) + Section 301 (25%) + Section 122 (10%).
- Applies to pure CTC or bulk chemicals not packaged as diagnostic/lab kits.
- Disadvantage: High cost impact on pure chemical imports.
🛠️ IV. Customs Clearance Practical Advice (Real-World Pitfall Avoidance Guide)
✅ 1. Required Documentation Checklist (None Can Be Omitted)
| Document | Mandatory? | Description |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must clearly state: "Contains Carbon Tetrachloride," intended use (Lab/Diagnostic vs. Industrial Solvent), concentration, and packaging type. |
| ✅ Certificate of Analysis (COA) | ✔️ | For pure CTC, proves purity. For kits, proves composition and stability. |
| ✅ Safety Data Sheet (SDS) | ✔️ | Crucial for CCl₄ due to toxicity. Must include handling, storage, and emergency measures. |
| ✅ Commercial Invoice | ✔️ | Must accurately describe goods as "Reagent Kit" or "Laboratory Chemical" if claiming 3822.19. Avoid vague terms like "Chemical Solvent" if classifying as reagent. |
| ✅ Packing List | ✔️ | Detail contents, especially if multiple components are included in a kit. |
| ✅ Labeling | ✔️ | Labels must match the declared HS Code purpose (e.g., "For Laboratory Use Only"). |
✅ 2. Declaration Strategy (Key Mantra)
🔥 "Kit for Lab, 10% Tax; Pure Solvent, 40.5% Tax!"
| Scenario | Correct Declaration | Incorrect Practice |
|---|---|---|
| Reagent Kit (Contains CTC + buffers, for lab tests) | 3822.19.00.10 or 3822.19.00.40 |
Misdeclare as 2903.19.60.50 → Higher tax? No, but if you misdeclare a kit as pure solvent, you may face scrutiny for under-declaring value/composition. |
| Pure Carbon Tetrachloride (Bulk or solvent grade) | 2903.19.60.50 |
Misdeclare as 3822.19 → High Risk of Audit, Penalty, and Back-Tariff (30.5% difference). |
| Kit with Additional Tools (e.g., vials, instructions) | Still 3822.19 (Kit) |
Splitting into "Chemical" + "Container" → Complex and potentially higher total duty. |
✅ 3. Special Handling for Carbon Tetrachloride
| Issue | Handling Advice |
|---|---|
| Toxicity Restrictions | CCl₄ is highly toxic. Ensure compliance with EPA and OSHA regulations. Provide SDS for all shipments. |
| Environmental Compliance | Verify if the destination country has additional bans or restrictions on halogenated hydrocarbons. |
| Packaging | Must be leak-proof and labeled with hazard symbols (Toxic, Flammable). |
| Documentation | Clearly state "Not for Human or Veterinary Use" if applicable, to avoid FDA/USDA scrutiny. |

📌 VI. Common Mistakes & Pitfall Guide (Lessons Learned)
❌ Mistake 1: Declaring a Reagent Kit as Pure Solvent (2903.19.60.50)
👉 Consequence: Unnecessary high tax (40.5% vs 10%). While you save on duty, you risk audit for misdescription.
👉 Better: Use 3822.19 for accurate classification.
❌ Mistake 2: Declaring Pure Solvent as Reagent Kit (3822.19)
👉 Consequence: Customs may reject the declaration if no kit components (buffers, vials, instructions) are present. Leads to demurrage, penalties, and back-tariff of 30.5%.
👉 Better: Always declare accurately. If it's pure CTC, use 2903.19.60.50.
❌ Mistake 3: Missing SDS (Safety Data Sheet)
👉 Consequence: CCl₄ is a hazardous material. Missing SDS leads to immediate detention or return of shipment.
👉 Better: Always include SDS in customs documentation.
🎯 VII. Conclusion: Accurate Classification Saves Money and Time
🎯 Remember the Mantra:
🔹 "Kit for Lab: 10% Duty. Pure Solvent: 40.5% Duty."
🔹 "Classify by Purpose, Not Just Name."
📌 Pro Tip:
- If your product is a mixture intended for lab use, ensure the primary purpose is diagnostic/research, not industrial solvent.
- Provide clear Product Descriptions like: "Carbon Tetrachloride-Based Cell Biology Reagent Kit for Laboratory Metabolism Studies" to support 3822.19 classification.
- For pure CTC, use: "Carbon Tetrachloride, Pure Grade, for Industrial Solvent Use" to support 2903.19.60.50.
📣 Immediate Action:
📞 Consult with a licensed customs broker for pre-classification.
📄 Prepare SDS and Product Specs.
🚀 Ensure accurate HS Code declaration to avoid costly penalties.

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
