Tetrafluoroethane Refrigerant High Purity

🧪 Fluorinated Refrigerants: Tetrafluoroethane (HFC-134a & HFC-134)

🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional通关 Strategy
📌 I. Product Definition & Classification: Do You Know "Tetrafluoroethane"?

Tetrafluoroethane is a halogenated derivative of hydrocarbons, specifically a saturated fluorinated derivative of acyclic hydrocarbons. In the international trade of chemicals, it is primarily used as a refrigerant in air conditioning systems, automotive cooling, and foam blowing.

It is strictly divided into two isomers based on molecular structure:

1,1,1,2-Tetrafluoroethane (HFC-134a):
The most common isomer used globally in automotive AC and household refrigerators. It is a stable, non-flammable (in standard conditions), ozone-depleting substance-free refrigerant.

1,1,2,2-Tetrafluoroethane (HFC-134):
A less common isomer, often used in specific industrial applications or as an intermediate in chemical synthesis.

⚠️ Key Distinction Point:
- If the product is 1,1,1,2-Tetrafluoroethane, it falls under HFC-134a.
- If the product is 1,1,2,2-Tetrafluoroethane, it falls under HFC-134.
- Note: Both are classified under the same HS Code subheading in this specific data context, but precise chemical identification is required for purity and safety documentation.

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

🔍 Key Reminder:
- This HS Code excludes other fluorinated derivatives not listed here (e.g., Chlorofluorocarbons/CFCs, Hydrochlorofluorocarbons/HCFCs, or Perfluorocarbons/PFCs).
- High Purity Requirement: For refrigerant-grade tetrafluoroethane, purity is typically >99.9%. Impurities (like HF, water, or other halocarbons) must be declared to avoid reclassification or safety hazards.
- Packaging: Typically imported in compressed gas cylinders, ISO tanks, or bulk containers. Ensure packaging meets IMDG (International Maritime Dangerous Goods) standards for Class 2.2 (Non-flammable, Non-toxic Gas) or Class 2.1 (Flammable, if applicable).

✅ Effective Time: 2026
(Note: The provided data is specific to Chinese tariff structures based on the input)

🎯 1. 2903.45.10.00 —— Tetrafluoroethane (HFC-134a & HFC-134)

📌 Explanation:
- The 3.7% basic tariff reflects China’s duty on specific fluorinated hydrocarbons used in refrigeration.
- No Additional Tariffs: As of the provided data, there are no additional retaliatory tariffs or special trade remedy duties applied to this specific HS Code in the given context.
- Comparison: Compared to some complex organic chemicals that may face higher duties, HFC-134a remains relatively low-cost in terms of tariff burden, but environmental regulations may apply.

🌍 V. Global Market Customs Comparison (2026 Latest)

📌 Conclusion:
- China offers a straightforward 3.7% tariff for HFC-134a/134, but environmental and safety compliance is critical.
- USA and EU have additional regulatory burdens (EPA, REACH) that can increase clearance time, even if tariff rates are competitive.
- Always verify UN Packaging and SDS compliance to avoid detention.

📌 VI. Common Mistakes & Pitfall Avoidance Guide (Lessons Learned)

❌ Mistake 1: Declaring "Refrigerant Gas" without specifying the isomer (HFC-134a vs. HFC-134)
👉 Consequence: Customs may hold the shipment for chemical analysis → Delay + Storage Fees

❌ Mistake 2: Using non-UN-certified cylinders for compressed gas
👉 Consequence: Seizure or Return due to safety violations

❌ Mistake 3: Ignoring Purity Requirements
👉 Consequence: If purity <99.9%, it may be classified as a mixture or crude chemical → Higher Tariff or Rejection

❌ Mistake 4: Failure to Provide SDS in Local Language
👉 Consequence: Customs clearance blocked until correct documentation is submitted → Delay

✅ Correct Practice:

"1,1,1,2-Tetrafluoroethane (HFC-134a), Purity ≥99.9%, CAS No. 811-97-2, UN1044, Class 2.2 Gas, in UN-certified Steel Cylinders, SDS Attached"

🎯 VII. Conclusion: Precision in Classification, Efficiency in Clearance!

🎯 Remember Mnemonic:

🔹 "High Purity, CAS Clear, UN Code Right, 3.7% Tariff Light!"
🔹 "HS Code 2903.45.10.00, Refrigerant Key, Safety First!"

📌 Pro Tip:
If you are importing HFC-134a for environmental-sensitive applications (e.g., food processing), ensure additional food-grade certifications are included.
For large-volume imports, consider Customs Bonded Warehouses to defer tax payment until release.
