π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Compliance Strategy
π I. Product Definition & Classification: What is "Methyl Chloroform"?
In international trade and chemical engineering, "Methyl Chloroform" typically refers to 1,1,1-Trichloroethane (1,1,1-TCA).
However, it is crucial to distinguish between the pure chemical substance and the mixture/formulation used for cleaning.
1. Pure 1,1,1-Trichloroethane (Industrial Grade):
A halogenated hydrocarbon solvent, historically used for degreasing and precision cleaning.
β οΈ Regulatory Status: Strictly regulated under the Montreal Protocol due to its ozone-depleting potential (ODP) and greenhouse gas effects. Production and import are heavily restricted or banned in many jurisdictions.
2. Methyl Chloroform Mixture for Precision Cleaning (Formulated Product):
A commercial mixture containing 1,1,1-TCA combined with other solvents (e.g., hydrofluoroethers, chlorinated fluorocarbons, or alcohols) to enhance cleaning efficiency and safety.
π Key Classification Rule:
- If the product is a mixture/formulation intended for a specific purpose (cleaning), it generally falls under HS Code 3824.
- If it is pure 1,1,1-TCA (>99%), it falls under HS Code 2903.β οΈ Critical Distinction:
- Pure Chemical β Chapter 29 (Organic Chemicals)
- Mixture/Formulation for Cleaning β Chapter 38 (Miscellaneous Chemical Products)
π¦ II. HS Code Classification Details (2026 Latest Tariff Authority)
| HS Code | Product Description | Applicable Scenario | Key Criteria |
|---|---|---|---|
| 2903.39.90 | Halogenated derivatives of acyclic hydrocarbons: Other (Pure 1,1,1-Trichloroethane) | Pure chemical solvent, raw material | Purity >95%, no other active ingredients |
| 3824.72.00 | Pre-mixed paints, varnishes, enamel... (Wait, no) β 3824.99.99 (Other chemical products) β Actually, 3824.72 is for Paints. Let's correct. | 3824.99.99 or 3824.72? No. For solvents in mixtures: 3824.99.99 is often used if not specified elsewhere. However, 3824.72 is for paints. 3824.99.99 is a residual category. Better Code: 3824.72.00 is incorrect. 3824.99.99 is common for miscellaneous solvent mixtures. Let's check 3824.72: "Pre-mixed paints..." No. Let's check 3824.99: "Other chemical products...". Alternative: If the mixture is dominated by 1,1,1-TCA, some customs authorities may still classify under 2903.39.90 if the other components are negligible. Standard Practice: 3824.99.99 (Miscellaneous Chemical Products) for formulated cleaning mixtures. |
Formulated cleaning solution, contains additives |
| 3402.90.00 | Organic surface-active agents (including wetting agents, etc.) | If the mixture contains significant surfactants/emulsifiers | Acts as a surfactant formulation |
π Key Reminder:
- Pure 1,1,1-TCA is classified under 2903.39.90.
- Formulated Mixture for cleaning is typically classified under 3824.99.99 (Miscellaneous Chemical Products) or 3402.90.00 if surfactants are key.
- DO NOT classify formulated mixtures as pure chemicals to avoid regulatory penalties.

π οΈ IV. Customs Clearance Practical Advice (Real-World Pitfall Avoidance Guide)
β 1. Document Checklist (Must-Have)
| Document | Required | Description |
|---|---|---|
| β Safety Data Sheet (SDS) | βοΈ | Must comply with OSHA HazCom Standard (Section 1-16). Must list all components if mixture. |
| β Product Specification Sheet | βοΈ | Define whether it is pure or mixture. Include CAS numbers for pure components. |
| β Commercial Invoice | βοΈ | Clearly state "Formulated Cleaning Mixture" or "1,1,1-Trichloroethane, Pure". Do not use vague terms like "Solvent". |
| β Certificate of Origin | βοΈ | If claiming FTZ or other exemptions (rare for China origin). |
| β Import License (EPA/EEA) | βοΈ | CRITICAL: 1,1,1-TCA is regulated. May require EPA registration or import notification. |
| β Filing 7501 | βοΈ | Entry Summary. Must declare accurate HTSUS code and duty calculation. |
β 2. Declaration Tips (Key Mantra)
π₯ "Pure vs. Mixture, SDS and CAS, EPA Rules, Don't Pass!"
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| Pure 1,1,1-TCA | HS: 2903.39.90, Name: "1,1,1-Trichloroethane, Pure" | Declaring as "Cleaning Solvent" β HS 3824 β Misclassification Penalty |
| Formulated Mixture | HS: 3824.99.99, Name: "Precision Cleaning Mixture" | Declaring as "Paint Remover" β HS 3824.72 β Incorrect Code |
| Non-Chinese Origin | Check for IEEPA Exemptions | Assuming all Chinese goods are taxed |
| Mixture with Unknown Components | Do Not Import without full disclosure | Hiding components β FDA/EPA Violation |
β 3. Special Handling
| Situation | Handling Advice |
|---|---|
| Ozone Depleting Substances (ODS) | 1,1,1-TCA is a Class I ODS. Import requires EPA Notification. Ensure you have the necessary permits. |
| Hazardous Materials (HazMat) | Classified as Flammable Liquid (Class 3) or Toxic (Class 6.1). Requires proper HazMat labeling and DOT compliance. |
| Small Samples | Even samples are subject to Section 301 tariffs. No de minimis exemption for chemicals. |
| Substitute Solvents | Consider HFE (Hydrofluoroethers) or D limonene alternatives. They may have lower tariffs or fewer regulatory hurdles. |
π V. Global Major Market Clearance Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff Rate (China Origin) | Certification Requirements | Notes |
|---|---|---|---|---|
| πΊπΈ USA | 2903.39.90 / 3824.99.99 |
40.6% - 40.8% | EPA Registration, OSHA SDS | Strict ODS regulations |
| π¨π³ China | 2903.39.90 |
5.0% - 6.0% | No Surtax | Production restricted |
| πͺπΊ EU | 2903.39.90 |
5.3% + REACH Compliance | REACH Registration, CLP Labeling | 1,1,1-TCA is Banned in EU under REACH for most uses |
| π―π΅ Japan | 2903.39.90 |
3.0% - 4.0% | PRTR Law Notification | Strict environmental controls |
| π¬π§ UK | 2903.39.90 |
5.3% + UK REACH | UK REACH Registration | Post-Brexit, similar to EU |
π Conclusion:
- USA is the only major market allowing import with high tariffs.
- EU/UK have effectively banned 1,1,1-TCA for most cleaning uses. Do not attempt to export to EU.
- China has restricted production. Exporting from China may be difficult due to domestic controls.
π VI. Common Mistakes & Pitfall Guide (Blood-Teaching Lessons)
β Mistake 1: Declaring "Cleaning Mixture" as "Paint Striper"
π Consequence: Incorrect HS Code β Penalty + Audit
β Mistake 2: Ignoring EPA Regulations for 1,1,1-TCA
π Consequence: Seizure of Goods + Fines ($10,000+ per day)
β Mistake 3: Claiming "De Minimis" Exemption for Samples
π Consequence: Back Taxes + Interest (No exemption for chemicals)
β Mistake 4: Not Listing All Ingredients in SDS
π Consequence: Customs Hold + FDA/EPA Investigation
β Correct Action:
"Formulated Precision Cleaning Mixture, Contains 1,1,1-Trichloroethane (CAS 71-55-6), SDS Attached, EPA Notification Number: XXXXX"
π― VII. Conclusion: Professional Declaration, Time-Saving, Cost-Effective!
π― Remember the Mantra:
πΉ "Pure is 2903, Mixture is 3824, EPA Rules are Key, SDS Must Be Ready!"
πΉ "Tariff is 40%, HazMat Labeling is Mandatory, Banned in EU, Think Twice!"
π Tips:
- If your product is a mixture with low 1,1,1-TCA content, check if it can be classified under 3402.90.00 (Surfactants) to potentially avoid Section 301 tariffs.
- Consider alternative solvents like HFE-7100 or Cyrene which may have more favorable tariff treatments and regulatory status.

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
