🧪 Carbon Tetrachloride ELISA Reagents & Laboratory Chemicals (四氯化碳ELISA/细胞/食品安全试剂)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Specialized Logistics Strategy
📌 I. Product Definition & Classification: What Exactly Are "Carbon Tetrachloride Reagents"?
These products are specialized chemical kits or solutions based on Carbon Tetrachloride (CCl₄). In international trade, they are not classified as simple solvents but as Diagnostic, Laboratory, or Biological Reagents. Their classification depends heavily on the specific application (ELISA, Cell Biology, Food Safety) and the formulation.
Key Distinction: * Diagnostic/ELISA Kits: Specifically formulated for detecting antigens/antibodies via ELISA methods. * General Laboratory Reagents: Chemicals used for cell biology assays or general lab testing. * Food Safety Reagents: Specific formulations for testing food samples.
⚠️ Critical Classification Point:
- If the primary function is diagnostic (e.g., ELISA) or laboratory testing (cell biology, food safety), it falls under HS Code 3822.19.
- The specific 8-digit sub-code distinguishes between different types of reagents (e.g.,10vs40).
- Crucially, these items are subject to Section 301 (122 Clause) Tariffs due to their chemical origin and trade policies.

🛠️ IV. Customs Clearance Practical Advice (Real-World Pitfall Avoidance Guide)
✅ 1. Documentation Checklist (Must-Provide)
| Document | Required | Notes |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must explicitly state: "Contains Carbon Tetrachloride," "Purpose: ELISA/Cell Biology/Food Safety" |
| ✅ Safety Data Sheet (SDS) | ✔️ | Crucial: CCl₄ is hazardous. SDS must comply with GHS standards for transport |
| ✅ Certificate of Analysis (COA) | ✔️ | To prove chemical composition and purity |
| ✅ Commercial Invoice | ✔️ | Clearly describe as "CCl₄ ELISA Reagent" or "Laboratory Reagent," not just "Chemical" |
| ✅ HS Code Pre-classification | ✔️ | Recommended to confirm 3822.19.00.10 vs 3822.19.00.40 based on exact product label |
| ✅ Import License (if applicable) | ✔️ | Check if CCl₄ requires special environmental/chemical import permits |
✅ 2. Declaration Tips (Key Mnemonics)
🔥 “Specify Purpose, Not Just Substance”
- Correct: "Carbon Tetrachloride ELISA Diagnostic Reagent" →3822.19.00.10
- Correct: "Carbon Tetrachloride Cell Biology Laboratory Reagent" →3822.19.00.40
- Incorrect: "Carbon Tetrachloride Solvent" → Risk of misclassification, potential penalties, and higher scrutiny for hazardous materials.
| Scenario | Correct Declaration | Risk if Incorrect |
|---|---|---|
| ELISA Kit | 3822.19.00.10 |
Misclassification → Delayed Clearance |
| Food Safety Test Kit | 3822.19.00.40 |
Misclassification → Duty Dispute |
| General Lab Reagent | 3822.19.00.40 |
Misclassification → Additional Review |
| Pure CCl₄ Solvent | Different HS Code (e.g., 2903.xx) | Wrong HS Code → Penalty for misdeclaration |
✅ 3. Special Considerations
| Situation | Handling Advice |
|---|---|
| Hazardous Material | CCl₄ is toxic and regulated. Ensure proper packaging and labeling (UN Class 6.1 or 8 depending on formulation). Provide SDS. |
| Mixed Kits | If the kit contains CCl₄ + other non-regulated items, declare the primary purpose (Diagnostic/Lab Reagent) under 3822. |
| US Origin vs China Origin | If reagents are manufactured in the US, no Section 122 tariff applies. Proof of Origin is Critical. |
| Small Samples | Even for samples, if CCl₄ is present, declare properly. Do not under-declare value. |
🌍 V. Global Market Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff Rate | Certification Required | Notes |
|---|---|---|---|---|
| 🇺🇸 USA | 3822.19.00.10 / .40 |
10% (Section 122) | SDS, GHS Labeling | High scrutiny on chemical reagents |
| 🇨🇳 China | 3822.19.00.10 / .40 |
0% - 5% | MSDS, Registration | Import regulation for hazardous chemicals |
| 🇪🇺 EU | 3822.19.00.10 / .40 |
0% - 6.5% | REACH Compliance | CCl₄ may be restricted under REACH; check SVHC list |
| 🇯🇵 Japan | 3822.19.00.10 / .40 |
0% - 6.2% | Chemical Substances Control Law | Strict import controls on CCl₄ |
📌 Conclusion:
- USA: 10% Additional Tariff is mandatory for China-origin goods.
- EU/Japan: Focus on REACH/Chemical Safety Compliance rather than just tariff rates. CCl₄ is heavily regulated environmentally.
📌 VI. Common Mistakes & Pitfalls (Lessons Learned)
❌ Mistake 1: Declaring as "General Chemical" without specifying "ELISA/Lab Reagent"
👉 Consequence: Customs may assign a generic code with higher scrutiny or duties.
❌ Mistake 2: Omitting SDS (Safety Data Sheet)
👉 Consequence: Shipment Held. CCl₄ is hazardous. Customs will request SDS immediately, causing delays.
❌ Mistake 3: Misclassifying as "Solvent" (e.g., 2903.xx) instead of "Reagent" (3822.xx)
👉 Consequence: Incorrect duty calculation and potential penalties for misdeclaration.
❌ Mistake 4: Assuming De Minimis Exemption applies
👉 Consequence: Even for small quantities, hazardous chemicals often require full declaration.
✅ Correct Approach:
"Carbon Tetrachloride-Based ELISA Diagnostic Reagent, for Laboratory Use, Contains CCl₄, SDS Attached, HS Code 3822.19.00.10"
🎯 VII. Conclusion: Precise Classification, Smooth Clearance, Cost Control!
🎯 Remember the Mnemonic:
🔹 "Reagent, Not Solvent! Specify ELISA or Lab Purpose!"
🔹 "CCl₄ Reagent = 3822.19 + 10% Tax! SDS Mandatory!"
📌 Pro Tip:
- If your product is not China-origin (e.g., manufactured in EU or US), the 10% Section 122 tariff does not apply. Provide Proof of Origin to claim 0% additional duty.
- Pre-clearance: For large shipments, consider filing an Advance Ruling with CBP to confirm the exact HS Code (10 vs 40) and avoid post-import audits.

About HS Code Classification
The Harmonized System (HS) is an internationally standardized nomenclature developed by the World Customs Organization (WCO) to classify traded products. Over 200 countries use the HS system as the basis for customs tariffs, trade statistics, and import/export regulations.
Each HS code follows a hierarchical structure:
- Chapter (2 digits) — Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) — More specific grouping within the chapter
- Subheading (6 digits) — Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) — Country-specific extensions for further classification, such as US HTSUS 10-digit codes
Correct HS code classification is essential for smooth customs clearance, accurate duty payment, and compliance with trade regulations. Misclassification can lead to customs delays, overpayment of duties, or penalties.
When importing from CN to US, the applicable tariff rates may include:
- Most-Favored-Nation (MFN) rate — The standard duty rate applied to WTO members
- General rate — Applied to countries without trade agreements
- Trade remedy duties — Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
