π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Customs Strategy
π I. Product Definition & Classification: What Are We Dealing With?
The user input "Trichloroethane Toxicology Research Reagent" refers to diagnostic or laboratory reagents used in toxicology research. Specifically, it contains 1,1,1-Trichloroethane (also known as Methyl Chloroform).
In international trade and customs classification, this product falls under Heading 3822: "Diagnostic or laboratory reagents on a backing; prepared diagnostic or laboratory reagents... other than those of heading 3006."
Because the reagent contains Methyl Chloroform (1,1,1-trichloroethane), it triggers a specific sub-heading exclusion. It is not considered a standard "other" reagent but rather one containing specific hazardous/regulated solvents, which dictates its HS Code and potential regulatory scrutiny.
β οΈ Key Distinction:
- If the reagent contains Methyl Chloroform or Carbon Tetrachloride β It is classified under 3822.19.00.40.
- If it contains no such chemicals β It is classified under 3822.19.00.80.
- This specific input contains Trichloroethane, so it MUST be classified under 3822.19.00.40.
π¦ II. HS Code Classification Details (2026 Latest Tariff Authority)
Based strictly on the provided <DATA>, here are the only two possible codes for "Diagnostic or laboratory reagents on a backing...":
| HS Code | Product Description | Applicability | Chemical Content |
|---|---|---|---|
3822.19.00.40 |
Diagnostic or laboratory reagents on a backing... Other... Containing methyl chloroform (1,1,1-trichloroethane) or carbon tetrachloride | Reagents specifically formulated or containing 1,1,1-Trichloroethane (Methyl Chloroform) or CCl4 | β YES (Contains 1,1,1-Trichloroethane) |
3822.19.00.80 |
Diagnostic or laboratory reagents on a backing... Other... Other | Reagents NOT containing methyl chloroform or carbon tetrachloride | β NO |
π Critical Note:
- Since the product is a "Trichloroethane Toxicology Research Reagent", it explicitly contains 1,1,1-Trichloroethane.
- Therefore, the only correct HS Code is3822.19.00.40.
- Classifying it under3822.19.00.80("Other") would be a misclassification because it fails to disclose the presence of the specific solvent mentioned in the description.

π― 1. 3822.19.00.40 ββ Reagents Containing Methyl Chloroform / Carbon Tetrachloride
| Item | Content |
|---|---|
| Basic Tariff | 0.0% |
| Additional Tariff | 0.0% |
| Total Tax Rate | 0.0% |
| Tax Detail | εΊη‘ε
³η¨: 0.0%, ε εΎε

| Risk Level | β οΈ Medium-High Regulatory Risk (See below) |
π Explanation:
- According to the provided data, the total tax is 0.0%. This is a zero-tariff item for basic and additional duties.
- However, the presence of 1,1,1-Trichloroethane (Methyl Chloroform) and Carbon Tetrachloride often triggers environmental and safety regulations (e.g., EPA regulations in the US, REACH in EU) that are not reflected in the tariff rate but can cause customs holds, inspections, or denial of entry if not properly documented.
- Zero tax does NOT mean zero effort.
π οΈ IV. Customs Clearance Practical Advice (Real-World Pitfall Guide)
β 1. Documentation Checklist (Non-Negotiable)
| Document | Must Provide | Explanation |
|---|---|---|
| β Material Safety Data Sheet (MSDS/SDS) | βοΈ Mandatory | Must explicitly state the concentration of 1,1,1-Trichloroethane and Carbon Tetrachloride. |
| β Product Composition Statement | βοΈ Mandatory | Detailed breakdown of ingredients, highlighting the specific chlorinated solvents. |
| β Laboratory Use Declaration | βοΈ Recommended | Confirm the product is for R&D/Laboratory Use Only (not for clinical diagnostics like HIV/Hepatitis tests which might fall under Heading 3006). |
| β Commercial Invoice | βοΈ Mandatory | Must accurately describe the item as "Laboratory Reagent containing 1,1,1-Trichloroethane" to match HS Code 3822.19.00.40. |
| β UN 3333 / Hazardous Goods Declaration | βοΈ If applicable | If the concentration of chlorinated solvents exceeds certain limits, it may be classified as dangerous goods for shipping. |
β 2. Declaration Tips (Key Mantra)
π₯ "Content is King, Solvent is King, Misclassification is Death!"
| Scenario | Correct Declaration | Wrong Action |
|---|---|---|
| Contains 1,1,1-Trichloroethane | HS Code: 3822.19.00.40 |
Declaring as 3822.19.00.80 β Penalty + Back Taxes + Seizure |
| Contains Carbon Tetrachloride | HS Code: 3822.19.00.40 |
Omitting mention of CCl4 β Environmental Violation |
| No Chlorinated Solvents | HS Code: 3822.19.00.80 |
Using 3822.19.00.40 unnecessarily β Delays in Inspection |
| Clinical Diagnostic Kit (e.g., HIV) | HS Code: 3006 (Not in Data) | Declaring as 3822.19.00.xx β Major Misclassification |
π Warning:
- 1,1,1-Trichloroethane (Methyl Chloroform) is an Ozone Depleting Substance (controlled under the Montreal Protocol).
- While the tariff is 0%, many countries restrict or ban the import of goods containing this chemical unless exempted for laboratory use.
- Ensure you have the necessary environmental permits or exemptions before shipping.
β 3. Special Case Handling
| Situation | Handling Advice |
|---|---|
| R&D Reagent with Mixed Solvents | If the reagent contains both standard solvents and methyl chloroform, it MUST be classified under 3822.19.00.40. |
| High Concentration of Solvent | If the solvent is the primary component, consult with customs broker if it might be classified as a chemical product (Chapter 29) instead. |
| Clinical vs. Research | If used for human diagnostic tests (e.g., blood tests), it MUST be under Heading 3006. If the description is "Toxicology Research," it is likely Lab Use, thus 3822. |

| π―π΅ Japan | 3822.19.00 |
Varies | Osaka Port often inspects chemical reagents closely. |
π Conclusion:
- Tariff is 0%, but Regulatory Risk is High.
- The key challenge is not the tax, but the environmental safety compliance due to the presence of 1,1,1-Trichloroethane.
π VI. Common Errors & Pitfalls (Lessons Learned)
β Error 1: Declaring as 3822.19.00.80 ("Other") because "it's just a reagent."
π Consequence: Customs detects Methyl Chloroform β Fine for Misclassification + Seizure.
β Error 2: Failing to declare the specific chemical content in the invoice.
π Consequence: Customs suspects hidden hazardous goods β Inspection Delay (Weeks/Months).
β Error 3: Assuming "Zero Tariff" means "No Documentation."
π Consequence: Lack of SDS/MSDS β Refused Entry by customs or carrier.
β Error 4: Confusing "Toxicology Research" with "Clinical Diagnostics."
π Consequence: If it's for human diagnosis, it MUST be under Heading 3006, not 3822. Misclassification leads to major penalties.
β Correct Practice:
"Laboratory Reagent for Toxicology Research, containing 1,1,1-Trichloroethane, HS Code: 3822.19.00.40, MSDS Provided, For R&D Use Only."
π― VII. Conclusion: Precision in Classification Saves Time
π― Remember:
πΉ "Zero Tax Doesn't Mean Zero Risk."
πΉ "Trichloroethane = 3822.19.00.40, Not .80."
πΉ "SDS is Your Passport for Chemical Reagents."
π Pro Tip:
- Always cross-check the Chemical Abstracts Service (CAS) numbers of the solvents in your reagent.
- If the reagent contains 1,1,1-Trichloroethane, ALWAYS use 3822.19.00.40.

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
