βοΈ Non Ozone Depleting Refrigerant Mixture (HFCs)
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Compliance Strategy
π I. Product Definition & Classification: What Exactly Are "HFC Refrigerants"?
In the context of international trade and environmental regulations, "Non Ozone Depleting Refrigerant Mixture" typically refers to Hydrofluorocarbons (HFCs). These are synthetic fluorinated gases used primarily in air conditioning, refrigeration, and heat pump systems. Unlike older chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons (HCFCs), HFCs do not damage the ozone layer, but they are potent greenhouse gases.
According to the provided data, this category specifically includes saturated fluorinated derivatives of acyclic hydrocarbons, most commonly: * HFC-125: 1,1,1,2,2-Pentafluoroethane * HFC-143a: 1,1,1-Trifluoroethane * HFC-143: 1,1,2-Trifluoroethane * HFC-134a: 1,1,1,2-Tetrafluoroethane
β οΈ Key Distinction:
- If the product is a pure chemical substance (bulk liquid/gas in cylinders/totes) intended for industrial use β Classified under HS Code 2903.44/2903.45.
- If the product is already filled into refrigerant cylinders for immediate consumer/commercial use, it may still fall under these codes but requires strict hazardous material declaration.
- Do NOT confuse with "Refrigerating Machinery" (HS Code 8418), which refers to the AC units themselves, not the gas inside.
π¦ II. HS Code Classification Details (2026 Latest Tariff Authority)
Based on the provided dataset, the classification for these specific fluorinated derivatives is as follows:
| HS Code | Product Description | Specific Compounds Covered | Key Attribute |
|---|---|---|---|
2903.44.10.10 |
Saturated fluorinated derivatives of acyclic hydrocarbons | 1,1,1,2,2-Pentafluoroethane (HFC-125) | Single pure compound (or primary component mix) |
2903.45.10.00 |
Saturated fluorinated derivatives of acyclic hydrocarbons | 1,1,1,2-Tetrafluoroethane (HFC-134a) 1,1,2,2-Tetrafluoroethane (HFC-134) |
Single pure compound (or primary component mix) |
π Critical Note:
- HFC-125 falls under2903.44(Pentafluoro).
- HFC-134a/134 falls under2903.45(Tetrafluoro).
- Mixtures: If the product is a blend (e.g., R-410A, which is a mix of R-32 and R-125), customs may still classify it under the primary HFC component if it meets the "derivative" definition, or require specific identification of the blend composition. Always check the SDS (Safety Data Sheet) for exact composition.

π οΈ IV. Customs Clearance Practical Advice (Pitfall Avoidance Guide)
β 1. Essential Documentation Checklist (Non-Negotiable)
| Document | Required? | Description |
|---|---|---|
| β Chemical Safety Data Sheet (SDS) | βοΈ Mandatory | Must clearly list CAS numbers for HFC-125 (354-33-6) and HFC-134a (811-97-2). Without CAS numbers, customs may misclassify. |
| β Certificate of Origin | βοΈ Mandatory | Required to verify the base tariff rate. |
| β Commercial Invoice | βοΈ Mandatory | Must explicitly state: "Saturated Fluorinated Derivatives of Acyclic Hydrocarbons" and specific HS Codes. |
| β Packing List | βοΈ Mandatory | Detail net weight vs. gross weight. Note if cylinders are pressurized. |
| β Import License (if applicable) | βοΈ Check Local Rules | In some countries, HFCs are regulated under environmental laws (e.g., Montreal Protocol/Kigali Amendment). Verify if a specific import permit is needed. |
| β Non-Ozone Depleting Certificate | βοΈ Recommended | Proof that the product does not contain CFCs/HCFCs to avoid stricter environmental tariffs. |
β 2. Declaration Tips (Key Mantras)
π₯ "CAS Number is King, Description Must Be Precise!"
| Scenario | Correct Declaration | Wrong Action |
|---|---|---|
| HFC-125 Import | HS: 2903.44.10.10Desc: "1,1,1,2,2-Pentafluoroethane (HFC-125), Saturated Fluorinated Derivative" |
Vague: "Refrigerant Gas" β Risk of random inspection & delay. |
| HFC-134a Import | HS: 2903.45.10.00Desc: "1,1,1,2-Tetrafluoroethane (HFC-134a)" |
Vague: "Air Conditioning Chemical" β Ambiguous classification. |
| Blended Refrigerant | Identify primary component OR use "Other" codes if mixture doesn't fit pure derivative definitions. | Assume all mixtures fit HFC-134a code. |
| Refrigerant in Cylinders | Declare as chemical product (HS 2903), not as "parts of AC" (HS 8418). | Misclassifying as machinery parts to seek lower duty (Risk of penalty). |
β 3. Special Circumstances Handling
| Situation | Handling Advice |
|---|---|
| Environmental Regulations | HFCs are controlled substances under the Kigali Amendment. Ensure compliance with local environmental agency rules, even if import duty is low. |
| Pressurized Cylinders | Classify as UN 3374 (Dangerous Goods) for transport. Must declare as "Non-flammable, Non-toxic Gas" (HFCs are generally Class 2.2). |
| Mixtures (e.g., R-404A, R-410A) | If not a pure HFC derivative, customs may require a more detailed chemical breakdown. Check if the mixture qualifies for the same HS code based on the dominant component. |
| Used/Recycled Refrigerant | Strictly Prohibited in many jurisdictions. New product only. Used refrigerants are often classified as waste. |
π V. Global Market Comparison (2026 Context)
| Country/Region | Recommended HS Code | Base Duty | Environmental Tax/Regulation | Notes |
|---|---|---|---|---|
| π¨π³ China | 2903.44.10.10 / 2903.45.10.00 |
3.7% (per data) | Quota System for HFCs | Strict production/import quotas under Kigali Amendment. |
| πΊπΈ USA | 2903.44.10.10 / 2903.45.10.00 |
Varies by Trade Act | SNPPA Program | EPA regulates HFCs under SNAP program. Higher duties may apply under Section 301. |
| πͺπΊ EU | 2903.44 / 2903.45 |
~3-6.5% | F-Gas Regulation | Heavy taxation on carbon-based HFCs (e.g., CO2e charge). |
| π―π΅ Japan | 2903.44 / 2903.45 |
~1.2-3.5% | Global Warming Prevention Law | Focus on low-GWP alternatives (HFOs). |
π Conclusion:
- Duty Rate: The base duty of 3.7% is competitive.
- Risk: The real cost is environmental compliance, not just customs duty.
- Strategy: Ensure your supplier provides a Kigali Amendment compliance certificate to avoid customs holds.
π VI. Common Errors & Pitfall Guide (Lessons Learned)
β Error 1: Using vague description "Refrigerant"
π Consequence: Customs asks for chemical composition, causing 10-30 day delays.
β
Fix: Always include HS Code + Chemical Name + CAS Number.
β Error 2: Confusing HFC-134a with HFO-1234yf
π Consequence: HFOs have different HS codes and lower environmental taxes. Misclassification leads to underpayment of environmental fees.
β
Fix: Verify the molecular structure: HFC (Fluorinated) vs. HFO (Fluorinated with double bond).
β Error 3: Ignoring Dangerous Goods (DG) Labeling
π Consequence: Shipment rejected at port because cylinders are not labeled as Class 2.2 Non-Flammable Gas.
β
Fix: Ensure packaging has correct UN numbers and DG labels.
π― VII. Conclusion: Professional Declaration for Smooth Clearance
π― Remember the Mantra:
πΉ "CAS Number is Key, HS Code Defines Duty, DG Label Ensures Safety."
πΉ "3.7% Duty is Simple, Environmental Rules are Complex."
π Pro Tip:
If you are importing large volumes, consider applying for a Binding Tariff Information (BTI) or Advance Ruling from local customs. This provides legal certainty on the HS code and prevents retrospective audits.
π£ Immediate Action:
π Verify CAS Numbers with your supplier.
π Check Kigali Amendment Compliance status.
π¦ Ensure DG Compliance for pressurized cylinders.

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
