π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Compliance Strategy π I. Product Definition & Classification: What is "Refrigerant Mixture"?
Refrigerant Mixtures containing PFCs (Perfluorocarbons) are complex chemical blends used primarily for cooling, air conditioning, and refrigeration. Unlike single-component refrigerants (like R-134a), these are blends of various hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sometimes other gases.
Key Characteristics: 1. PFC Content: PFCs are greenhouse gases with extremely high Global Warming Potential (GWP). Their presence triggers strict environmental regulations. 2. Mixture Nature: The specific ratio of components determines the boiling point and efficiency. Common examples include R-404A, R-410A, or custom industrial blends. 3. Packaging: Typically supplied in steel or aluminum cylinders under pressure.
β οΈ Critical Distinction: * If it is a pure chemical (e.g., pure Perfluoromethane CF4) β Often classified under 2903 (Halogenated Hydrocarbons). * If it is a mixture/blends designed for refrigeration β Classified under 2903.49.25 or similar HFC/PFC mixture codes, not pure PFCs like SF6 (which may fall under 2903.49.80 or other categories depending on purity). * Important: Do not confuse with "Compressed Air" (8414) or "Gas for welding" (3824). These are specialized chemical agents.
π¦ II. HS Code Classification Details (2026 Latest Tariff Authority)
| HS Code | Product Description | Application Scenario | PFC/HFC Status |
|---|---|---|---|
| 2903.49.25 | Halogenated hydrocarbons, other than olefins: Fluorinated hydrocarbons (HFCs, PFCs, etc.) β Mixtures | Primary Code for Refrigerant Blends. Covers mixtures like R-404A, R-407C, R-410A, etc., containing PFCs/HFCs. | β Mixture (Contains PFC/HFC blends) |
| 2903.49.10 | Fluorinated hydrocarbons (HFCs) β Single components (e.g., HFC-134a, HFC-125) | Pure single-component refrigerants. | β Single Component (If pure) |
| 2903.49.80 | Other halogenated hydrocarbons (Non-fluorinated, e.g., Chlorofluorocarbons CFCs - banned, or Bromofluorocarbons) | Old CFCs (banned), HCFCs (phase-out), or non-fluorinated halogenated gases. | β οΈ Restricted/Banned |
| 3824.99.91 | Other chemical products & preparations (if not solely for refrigeration) | Industrial cleaning agents containing fluorocarbons, or non-refrigerant uses. | β οΈ Different Purpose |
π Key Reminder: * Refrigerant Mixtures (blends of HFCs/PFCs) MUST go under 2903.49.25. * If the product is a pure PFC (e.g., pure Perfluorohexane), it may fall under 2903.49.10 or 2903.49.80 depending on exact composition. * Do not use 8414 (Air Pumps/AC Compressors) for the gas itself. Only the equipment goes in 8414.

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
