π One Product, One Tax: Master the R125 Refrigerant Mixture with Precision
π δΈγProduct Definition & Classification: What Exactly Is R125?
R125 (Pentafluoroethane) is a saturated fluorinated hydrocarbon used primarily as a refrigerant in air conditioning and heat pump systems. It is often blended with other HFCs (like R32, R134a) to form low-global-warming-potential (GWP) refrigerant mixtures for commercial and industrial cooling applications.
β οΈ Key Classification Insight:
- Pure R125 β Classified under 2903.44.10.10
- R125-containing mixtures (e.g., R404A, R507A) β Classified under 3824.99.55.00
- Not to be confused with gaseous hydrocarbons (2711.19.00.20 / 2711.29.00.60), which are not refrigerants but raw petrochemicals.

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
