HS Code for HFC-236fa

HFC-236fa, or 1,1,1,3,3,3-hexafluoropropane, is classified under HS code 2903.46. This subheading groups several saturated fluorinated derivatives of acyclic hydrocarbons together, including HFC-227ea, HFC-236cb, HFC-236ea, and HFC-236fa. The classification is based on the chemical structure as a saturated fluorinated hydrocarbon. Like other fluorinated gases in Chapter 29, this code applies to the chemically defined compound in its pure state. It is widely used in fire suppression systems as a clean agent and as a specialty refrigerant in high-ambient temperature applications. Accurate classification is necessary for compliance with international environmental treaties like the Kigali Amendment to the Montreal Protocol, which tracks the production and consumption of these substances. Because 2903.46 covers multiple specific chemicals, the commercial name or chemical formula must be clearly stated on shipping documentation to verify that the product belongs in this specific group rather than a general "other" category.

Products Included

• 1,1,1,3,3,3-Hexafluoropropane (HFC-236fa)
• FE-36 fire extinguishing agent (pure)
• HFC-227ea (Heptafluoropropane)
• HFC-236ea isomers
• Saturated fluorinated acyclic hydrocarbons listed in 2903.46

Common Misclassification

HFC-236fa is commonly misclassified under 2903.45, which covers other saturated fluorinated derivatives not specifically named in 2903.41 through 2903.44. Another error is classifying it under 3813.00 if it is imported as part of a prepared fire extinguisher charge. If the chemical is mixed with other agents, it must be classified in Chapter 38 rather than the pure chemical heading of 2903.

FAQ

What is the HS code for HFC-236fa?

The HS code for pure HFC-236fa is 2903.46.

Can HFC-236fa be classified under Chapter 38?

Only if it is part of a mixture or a prepared chemical formulation. In its pure, chemically defined form, it must stay in 2903.46.
