🧪 Carbon Tetrachloride Food Safety Reagents (Laboratory/Detection Grade)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 1. Product Definition & Classification: What exactly is "Carbon Tetrachloride Food Safety Reagent"?
Carbon Tetrachloride ($CCl_4$) reagents, specifically designated for Food Safety purposes, are specialized chemical agents used in laboratory testing and detection processes. In international trade, these are classified not merely as raw chemicals, but as Diagnostic/Reagent preparations (Chapter 38), tailored for specific analytical applications.
Key Classification Distinction:
- Laboratory/Detection Reagents: Specifically formulated or packaged for food safety analysis (e.g., residue testing, purity checks). These fall under 3822.19.00.40.
- Immuno/Cell Biology Reagents: Used for biological assays, immunology, or cellular studies. These fall under 3822.19.00.10.
⚠️ Critical Distinction Point:
- If the primary purpose is Food Safety Analysis (chemical detection, residue testing) → Classify as 3822.19.00.40.
- If the primary purpose is Biological/Immune Assay (antibody testing, cell culture) → Classify as 3822.19.00.10.
- Note: Both categories involve Carbon Tetrachloride as a material, but their end-use dictates the HS Code.

🛠️ 4. Customs Clearance Practical Advice (实战避坑指南)
✅ 1. Required Documentation Checklist (No Exceptions)
| Document | Mandatory? | Explanation |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must explicitly state: "Contains Carbon Tetrachloride," "For Food Safety/Detection Use." |
| ✅ Safety Data Sheet (SDS/MSDS) | ✔️ | Critical for hazardous chemicals. Must be GHS-compliant and issued within the last year. |
| ✅ Commercial Invoice | ✔️ | Clearly describe the product as "Carbon Tetrachloride Reagent" and specify the HS Code. |
| ✅ Packing List | ✔️ | Detail net/gross weight. Hazardous materials require specific packaging declarations. |
| ✅ Usage Declaration | ✔️ | Proof that it is for Laboratory/Testing use only (not for human consumption or industrial cleaning). |
✅ 2. Declaration Tips (Key Mantras)
🔥 “Declare Hazard, Specify Use, Avoid Misclassification!”
| Scenario | Correct Declaration Method | Incorrect Practice |
|---|---|---|
| Food Safety Reagent | 3822.19.00.40 |
Misclassifying as generic chemical 2903.14.00 → Risk of penalty |
| Immuno Reagent | 3822.19.00.10 |
Misclassifying as biological product 3002.90.00 → Incorrect tariff/duty |
| Kit Form | 3822.19.00.40 |
Declaring as loose chemicals → Packaging compliance issues |
| Contains CCl4 | Must declare Hazardous | Hiding CCl4 content → Seizure + Fine |

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
