π§ͺ Methyl Chloroform (1,1,1-Trichloroethane) Cell Antigen Detection Reagent
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
π I. Product Definition & Classification: What exactly is this reagent?
Diagnostic or laboratory reagents on a backing, specifically those prepared for antigen/antibody detection, containing hazardous solvents like Methyl Chloroform (1,1,1-trichloroethane) or Carbon Tetrachloride. These are specialized chemical reagents used in immunoassays, typically immobilized on a solid support (backing) such as paper, plastic, or glass.
β οΈ Key Distinction:
- If the reagent is on a backing (e.g., test strips, coated slides) and contains specific organic solvents β It falls under Chapter 38 (Miscellaneous Chemical Products).
- It is NOT heading 3006 (Bandages, dressings, etc.) unless explicitly stated as such.
- The presence of Methyl Chloroform (1,1,1-trichloroethane) or Carbon Tetrachloride triggers specific subheadings under 3822.
π¦ II. HS Code Classification Details (2026 Latest Tariff Authoritative Mapping)
Based on the provided data, the product falls under two specific subheadings depending on the precise formulation structure. Both carry the same tax rate.
| HS Code | Product Description | Key Characteristics | Applicable Scenario |
|---|---|---|---|
3822.19.00.10 |
Diagnostic or laboratory reagents on a backing, prepared reagents whether or not on a backing, whether or not put up in kits: Other, Containing antigens or antisera: Containing methyl chloroform (1,1,1-trichloroethane) or carbon tetrachloride | Reagents on a backing, specific solvent content | Immunoassay kits, coated test strips with specified solvents |
3822.19.00.40 |
Diagnostic or laboratory reagents on a backing, prepared reagents whether or not on a backing, whether or not put up in kits: Other, Other: Containing methyl chloroform (1,1,1-trichloroethane) or carbon tetrachloride | Reagents on a backing, specific solvent content, "Other" category | Similar to above, but classified under "Other" if not strictly antigens/antisera |
π Critical Note:
- Both codes explicitly require the presence of Methyl Chloroform (1,1,1-trichloroethane) or Carbon Tetrachloride.
- If these solvents are NOT present, the product may fall under a different3822subheading (e.g.,3822.00general reagents).
- Certified Reference Materials are also included in this chapter but are distinct from routine diagnostic reagents.

| β Safety Data Sheet (SDS) | βοΈ | Crucial for hazardous chemicals. Must comply with GHS standards |
| β Manufacturerβs Declaration | βοΈ | Confirming the product is a "diagnostic reagent on a backing" |
| β Commercial Invoice | βοΈ | Clearly describe as "Diagnostic Reagent on Backing" |
| β Packing List | βοΈ | Detail packaging to ensure no hazardous material violations |
| β Import License (if applicable) | βοΈ | Check if 1,1,1-trichloroethane requires a specific chemical import permit |
β 2. Declaration Tips (Key Mantras)
π₯ βSpecify Solvent, Confirm Backing, SD Must Match, Tax Zero!β
| Scenario | Correct Declaration | Wrong Approach |
|---|---|---|
| Reagent on paper/plastic backing | 3822.19.00.10 or .40 |
Declaring as "General Chemical" β 3822.00 (may have higher duties or different regulations) |
| Contains 1,1,1-trichloroethane | Explicitly name it in description | Vague term "Solvent" β Customs may flag for hazardous review |
| Kit form | State "Whether or not in kits" | Hiding kit components β Risk of misclassification |
| Non-backing reagent | NOT 3822.19 | Declaring as 3822.19 β Major Classification Error |
β 3. Special Circumstances Handling
| Situation | Handling Advice |
|---|---|
| Hazardous Chemical Permit | 1,1,1-trichloroethane is a controlled substance in many countries. Check local EPA/Environmental regulations for import permits. |
| SDS Consistency | The SDS must match the commercial invoice description. Any discrepancy leads to delays or fines. |
| Certified Reference Materials | If the product is a "Certified Reference Material," still use 3822, but ensure the description reflects its certified status. |
| Anti-Dumping/Countervailing | No additional taxes are listed for these codes, but verify if the country of origin triggers any specific bilateral agreements. |

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
