π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Strategy
π I. Product Definition & Classification: What is "Carbon Tetrachloride Metabolism Reagent"?
Carbon tetrachloride (CClβ) 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.
β οΈ Key Distinction Point:
- If the product is packaged as a "Kit" or "Reagent" intended for lab/diagnostic analysis (even if it contains CTC) β Classified under Chapter 38 (3822.19).
- If the product is Pure Carbon Tetrachloride used as a solvent or raw chemical β Classified under Chapter 29 (2903.19).
π¦ 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% |
π 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.

π οΈ IV. Customs Clearance Practical Advice (Real-World Pitfall Avoidance Guide)
β 1. Required Documentation Checklist (None Can Be Omitted)
| Document | Mandatory? | Description |
|---|---|---|
| β Product Specification Sheet | βοΈ | Must clearly state: "Contains Carbon Tetrachloride," intended use (Lab/Diagnostic vs. Industrial Solvent), concentration, and packaging type. |
| β Certificate of Analysis (COA) | βοΈ | For pure CTC, proves purity. For kits, proves composition and stability. |
| β Safety Data Sheet (SDS) | βοΈ | Crucial for CClβ due to toxicity. Must include handling, storage, and emergency measures. |
| β Commercial Invoice | βοΈ | Must accurately describe goods as "Reagent Kit" or "Laboratory Chemical" if claiming 3822.19. Avoid vague terms like "Chemical Solvent" if classifying as reagent. |
| β Packing List | βοΈ | Detail contents, especially if multiple components are included in a kit. |
| β Labeling | βοΈ | Labels must match the declared HS Code purpose (e.g., "For Laboratory Use Only"). |
β 2. Declaration Strategy (Key Mantra)
π₯ "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 β 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 β High Risk of Audit, Penalty, and Back-Tariff (30.5% difference). |

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) β Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) β More specific grouping within the chapter
- Subheading (6 digits) β Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) β 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 β The standard duty rate applied to WTO members
- General rate β Applied to countries without trade agreements
- Trade remedy duties β Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
