Methyl Chloroform Solvent

🧪 Methyl Chloroform Solvent (1,1,1-Trichloroethane)

🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition & Classification: What Exactly is "Methyl Chloroform"?

Methyl Chloroform, chemically known as 1,1,1-Trichloroethane (1,1,1-TCA), is a colorless, volatile, non-flammable liquid with a pleasant, ether-like odor. Historically, it was widely used as an industrial solvent for degreasing metals, cleaning electronics, and dry cleaning.

However, in international trade, it is heavily regulated due to its status as an Ozone Depleting Substance (ODS) under the Montreal Protocol. While its production and import for new uses are banned in many developed nations (including the US and EU) under international treaties, it may still exist in stockpile supplies, intermediate chemical uses, or exempted industrial applications depending on local laws.

⚠️ Critical Distinction:
- Pure 1,1,1-Trichloroethane: Strictly controlled; often requires specific permits.
- 1,1,2-Trichloro-1,2,2-trifluoroethane (CFC-113) or Trichloroethylene: Different HS codes and regulations. Do NOT confuse these.
- Methyl Chloride (Chloromethane): A different chemical (CH₃Cl), used in silicones; different HS code.

⚠️ Key Classification Point:
- If it is pure 1,1,1-Trichloroethane, it falls under Chlorinated Hydrocarbons (Chapter 29).
- If it is a preparation/mixture containing 1,1,1-TCA as a major component, it may fall under Chapter 38 (Miscellaneous Chemical Products).
- Most Common Import Scenario: Regulated ODS under special license.

📦 II. HS Code Classification Details (2026 Latest Tariff Authority)

🔍 Priority Note:
- HS Code 2903.39.10 is the correct code for pure 1,1,1-Trichloroethane.
- Customs authorities will scrutinize this code heavily due to environmental protection laws.
- Do NOT classify as general solvent (3824.99.95) if it is pure TCA, as this may lead to seizure or fines for misdeclaration of regulated substances.

💰 III. 2026 Latest Tariff Rate Breakdown (Including Surtaxes, Policy Surcharges)

✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Date: 2025-11-10 onwards (including subsequent imports)

🎯 1. 2903.39.10 —— 1,1,1-Trichloroethane (Pure)

📌 Interpretation:
- The 4.2% base rate is standard for halogenated hydrocarbons.
- The 25% Section 301 tariff applies to all Chinese-origin chemicals under this code.
- The 10% IEEPA tariff is newly enforced from Nov 2025 for Chinese goods.
- Total 39.2% is a very high cost, often exceeding the product value.
- Environmental Permits: In addition to tariffs, you must obtain a EPA Permit or Stockpile Exemption Certificate to import. Without it, the goods will be rejected regardless of tariff payment.

🎯 2. 3824.99.95 —— Mixtures/Preparations (Non-Pure)

📌 Note:
- If the solvent is a mixture (e.g., blended with other agents for specific degreasing), it may fall under 3824.99.95.
- Tariff is slightly higher (40.7%) due to different base rate.
- Still requires EPA documentation if 1,1,1-TCA content exceeds exempted thresholds.

🛠️ IV. Customs Clearance Practical Advice (Battle-Tested Pitfall Guide)

✅ 1. Required Documentation Checklist (Non-Negotiable)

✅ 2. Declaration Tips (Key Mantra)

🔥 “Chemical Name Exact, EPA Permit Ready, HS Code Precise, Avoid Seizure!”

✅ 3. Special Circumstances Handling

🌍 V. Global Market Customs Comparison (2026 Latest)

📌 Conclusion:
- USA is one of the few places where import is still possible with permits, but tariffs are prohibitive (39.2%).
- EU/UK effectively ban commercial import for new uses.
- High Tariff + Regulatory Hurdles make 1,1,1-TCA imports from China economically unviable for most new uses. Consider alternatives (e.g., HCFCs, HFOs, aqueous cleaners).

📌 VI. Common Errors & Pitfall Guide (Lessons Learned)

❌ Error 1: Declaring as “Industrial Solvent” or “Chloroform” without specifying “1,1,1-Trichloroethane”
👉 Consequence: Customs detects mismatch → Fine + Seizure + Potential Legal Action

❌ Error 2: Ignoring EPA Permit Requirements
👉 Consequence: Shipment held at port → Demurrage Charges → Deportation/Destroy

❌ Error 3: Confusing 1,1,1-TCA with Trichloroethylene (TCE) or CFC-113
👉 Consequence: Wrong HS Code → Tariff Misclassification Penalty

❌ Error 4: Using De Minimis Exemption for Small Packages
👉 Consequence: Denied: Regulated substances are excluded from de minimis thresholds in the US.

✅ Correct Practice:

“1,1,1-Trichloroethane (Pure), CAS No. 71-55-6, for Industrial Degreasing, EPA Stockpile Permit Attached, UN 1712, Hazard Class 3 (Non-flammable regulated chemical)”

🎯 VII. Conclusion: Professional Declaration, Risk Mitigation, Cost Efficiency

🎯 Remember the Mantra:

🔹 “Chemical Name Exact, EPA Permit Ready, Tariff 39.2%, No De Minimis!”
🔹 “HS Code 2903.39.10, Not 3824, Avoid Seizure, Save Your Business!”

📌 Pro Tip:
- If your product is a mixture, ensure the SDS clearly states the percentage of 1,1,1-TCA. If <5%, it may avoid strict ODS controls but still face high tariffs.
- Pre-Ruling Request: Submit an Advance Ruling to CBP with SDS and EPA permits to confirm HS Code and regulatory status before shipping.
- Alternative Search: Consider 1,1,2-Trichloro-1,2,2-trifluoroethane (CFC-113) or Hydrochlorofluorocarbons (HCFCs) if 1,1,1-TCA is banned in your destination, but check their specific regulations.

📣 Immediate Action:

📞 Contact EPA-licensed broker + Provide SDS + Apply for Advance Ruling
🚀 Ensure your solvent shipment cleans up, clears customs, and complies with global regulations!
