Tetrafluoroethane Refrigerant (400g)

❄️ Tetrafluoroethane Refrigerant (400g Containers)

🌐 HS Code Classification & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Compliance Strategy
📌 I. Product Definition & Classification: What is "Tetrafluoroethane" Really?

Tetrafluoroethane (specifically HFC-134a and related isomers like HFC-134) is a hydrofluorocarbon widely used as a refrigerant in automotive air conditioning, domestic refrigerators, and commercial cooling systems.

In international trade, its classification depends heavily on chemical specificity and packaging: 1. Specific Chemical Derivatives: If the product is clearly identified as a specific halogenated derivative (e.g., 1,1,1,2-Tetrafluoroethane), it falls under Chapter 29 (Organic Chemicals). 2. General Refrigerant Mixes: If it is a mixture or "not elsewhere specified," it may fall under Chapter 38 (Miscellaneous Chemical Products).

⚠️ Key Distinction:
- If the composition is pure/specific HFC-134a →归入 2903.45.10.00 (Specific Halogenated Derivative)
- If it is a generic mixture or described vaguely as "other chemical products" →归入 3824.90 or 2903.39 (Miscellaneous/Not Elsewhere Specified)

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

🔍 Critical Note:
- The most precise classification for HFC-134a is 2903.45.10.00.
- If you ship "Tetrafluoroethane" without specifying the isomer (1,1,1,2 vs 1,1,2,2), customs may scrutinize it.
- HFC-125 and HFC-143a have 0% base duty, making them more cost-effective if part of your product line.

💰 III. 2026 Latest Tariff Rate Breakdown (Detailed Tax Clause Explanation)

✅ Applicable Jurisdiction: China (CN) Import Tariff Structure
✅ Validity: Based on provided data for 2026

🎯 1. 2903.45.10.00 — 1,1,1,2-Tetrafluoroethane (HFC-134a)

📌 Explanation:
- This is the standard base tariff for specific saturated fluorinated derivatives of acyclic hydrocarbons.
- No additional punitive tariffs are listed in the provided data for this code.
- Net Weight Note: The product is packaged in 400g containers, which affects the net weight declaration but does not change the HS code.

🎯 2. 2903.44.10.10 — Pentafluoroethane (HFC-125) / HFC-143a

📌 Note:
- If your product is HFC-125 or HFC-143a, no duty is payable under this classification.
- This highlights the importance of precise chemical identification.

⚠️ 3. 2903.39 & 3824.90 — Generic/Unclassified Refrigerants

📌 Warning:
- If you misclassify HFC-134a as "Other fluorinated hydrocarbons" (2903.39) or "Other chemical products" (3824.90), the system cannot retrieve the correct tax.
- This leads to customs delays, audits, or manual assessment by customs officers, potentially resulting in higher penalties or backdated duties.

🌍 V. Global Market Comparison (2026 Latest)

📌 Conclusion:
- China offers a clear 3.7% rate for HFC-134a if correctly classified.
- HFC-125/143a are duty-free (0%) in this dataset, offering a cost advantage.
- Misclassification into 2903.39 or 3824.90 results in tax retrieval errors and customs delays.

📌 VI. Common Mistakes & Pitfalls (Lessons Learned)

❌ Mistake 1: Declaring as "Refrigerant" without specifying the chemical name
👉 Consequence: Customs may assign 3824.90 → Tax Retrieval Error → Delay + Penalties

❌ Mistake 2: Ignoring the Isomer (1,1,1,2 vs 1,1,2,2)
👉 Consequence: HFC-134a (1,1,1,2) is 3.7%, but other derivatives may have different rates. Specificity is key.

❌ Mistake 3: Using "Not Elsewhere Specified" (NES) codes for pure chemicals
👉 Consequence: NES codes are for mixtures or unlisted items. Pure HFC-134a has a specific code. Misuse leads to audits.

✅ Correct Practice:

"1,1,1,2-Tetrafluoroethane (HFC-134a), Pure, 400g Cylinders, For Refrigeration Use, HS Code: 2903.45.10.00"

🎯 VII. Conclusion: Precision Pays Off

🎯 Remember the Mantra:

🔹 "Specific Name, Specific Code, 3.7% or 0%, Avoid the Error!"
🔹 "HFC-134a: 3.7%, HFC-125: 0%, Generic: Risk!"

📌 Pro Tip:

• If you are exporting HFC-125 or HFC-143a, highlight the 0% duty rate to customers.
• For HFC-134a, ensure the chemical name matches 2903.45.10.00 exactly to avoid "Failed to Retrieve Tax" errors.
• Always include Net Weight (400g) in the invoice to clarify container quantity.

📣 Immediate Action:

📞 Contact your customs broker with the exact chemical name (Isomer) and request HS Code pre-classification.
