HS Code for HFC-143

The classification of HFC-143 and related compounds falls under HS code 2903.44. This code covers saturated fluorinated derivatives of acyclic hydrocarbons, specifically pentafluoroethane (HFC-125), 1,1,1-trifluoroethane (HFC-143a), and 1,1,2,2-tetrafluoroethane (HFC-143). As part of Chapter 29 (Organic Chemicals), heading 2903, this subheading is part of a structured effort to categorize halogenated derivatives based on their specific halogen content and molecular structure. These chemicals are primarily used as refrigerants, blowing agents, or propellants. The classification is determined by the chemical purity and the specific isomers present. HFC-143a, for instance, is a common component in refrigerant blends like R-404A and R-507. However, when classified under 2903.44, the product must be a separate chemically defined compound. The precision of this subheading allows for detailed tracking of substances with high global warming potential (GWP), ensuring that international trade data aligns with environmental regulatory requirements such as the Montreal Protocol and its subsequent amendments.

Products Included

• Pure 1,1,1-Trifluoroethane (HFC-143a)
• Pure 1,1,2-Trifluoroethane (HFC-143)
• Pure Pentafluoroethane (HFC-125)
• Saturated fluorinated acyclic hydrocarbons (143/125 series)
• HFC-143a gas for industrial use

Common Misclassification

The most frequent error is confusing 2903.44 with 2903.45 (which covers HFC-134). While both are saturated fluorinated derivatives, they contain different numbers of fluorine atoms. Additionally, mixtures containing HFC-143a (such as R-404A) are often incorrectly classified here; they should be under 3827.51 or similar codes for mixtures. Pure compounds must be at least 95% pure to qualify for Chapter 29.

FAQ

What is the HS code for HFC-143?

The HS code for pure HFC-143 and its isomer HFC-143a is 2903.44.

What is the difference between HFC-143 and HFC-134 in the HS system?

HFC-143 (trifluoroethane) is classified under 2903.44, while HFC-134 (tetrafluoroethane) is classified under 2903.45 based on the number of fluorine atoms in the molecule.
