π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
π I. Product Definition & Classification: What is "Carbon Tetrachloride Diagnostic Reagent"?
Carbon Tetrachloride (CClβ) Diagnostic Reagent is a specialized laboratory or clinical chemical product used primarily for cell biology, antigen detection, or diagnostic testing.
In international trade, it is classified not as a simple chemical solvent, but as a diagnostic/analytical reagent containing specific active ingredients (Carbon Tetrachloride) for medical or biological research purposes.
β οΈ Key Distinction Points:
- If the product is pure Carbon Tetrachloride used as a solvent or industrial chemical β It falls under Chapter 29 (Organic Chemicals).
- If the product is formulated as a reagent for cell biology, antigen detection, or diagnostic purposes β It falls under Chapter 30 or 38 (Pharmaceuticals/Diagnostic Kits).
- Crucial Note: The presence of "Diagnostic", "Cell Biology", or "Antigen" in the description triggers the medical/diagnostic classification, regardless of the chemical content.

| β Letter of Declaration | βοΈ | Confirming non-military use and intended purpose (Lab vs. Clinical). |
β 2. Declaration Best Practices
π₯ "Clarify Purpose, Declare Accurate, Avoid Misclassification!"
| Scenario | Correct Declaration | Risk of Error |
|---|---|---|
| Lab Research Reagent | Use HS 3822.19.00.10 or 3822.19.00.40Description: "Carbon Tetrachloride Lab Reagent for Cell Biology" |
Low risk if purpose is clearly lab-based. |
| Patient Diagnostic Kit | Use HS 3006.30.50.00 or 3006.30.10.00Description: "Antigen Diagnostic Reagent with CClβ" |
High risk if not FDA-cleared; requires FDA number. |
| Antigen Detection Kit | Use HS 3002.90.52.50Description: "Blood-based Antigen Detection Reagent" |
Must prove immunological/blood component origin. |
π Critical Tip:
- Do NOT declare as "Organic Solvent" (Chapter 29) if it is formulated as a diagnostic reagent. This leads to misclassification penalties and potential FDA seizure.
- Always include "Diagnostic" or "Lab Reagent" in the product name on the commercial invoice.
β 3. Special Considerations
| Issue | Recommendation |
|---|---|
| Carbon Tetrachloride (CClβ) Content | CClβ is a regulated substance. Ensure compliance with EPA and DOT hazardous material regulations. |
| FDA Compliance | If the product is for clinical diagnostics (patient use), it must be registered with the FDA. Lab-only use has fewer restrictions. |
| 122 Clause Impact | The 10% tax is mandatory. Factor this into pricing and profit margins. |

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
