HS Code for HFC-23 mixtures
Mixtures containing HFC-23 (trifluoromethane) are classified under HS code 3827.59. This classification is a result of the 2022 Harmonized System updates, which introduced heading 3827 to specifically address mixtures containing halogenated derivatives of methane, ethane, or propane. Unlike pure HFC-23, which is classified as a chemically defined compound in Chapter 29, mixtures are classified in Chapter 38 (Miscellaneous Chemical Products). Subheading 3827.59 is a residual category for mixtures containing HFC-23 or perfluorocarbons (PFCs) that do not contain chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons (HCFCs). This classification is critical for environmental reporting, as HFC-23 is a potent greenhouse gas often produced as a byproduct. The inclusion of PFCs in this subheading also ensures that various high-GWP industrial gas blends are captured for regulatory oversight.
Products Included
- Mixtures containing trifluoromethane (HFC-23)
- Mixtures containing perfluorocarbons (PFCs)
- Refrigerant blends like R-508B (containing HFC-23)
- Industrial gas mixtures without CFCs or HCFCs
Common Misclassification
The most frequent error is classifying these mixtures under HS code 2903.41, which is reserved exclusively for pure HFC-23. Another common misclassification is 3827.51, which is specifically for mixtures containing certain other HFCs. Importers must distinguish between pure substances and blends to avoid customs penalties and incorrect environmental quota deductions.
FAQ
What is the HS code for mixtures containing HFC-23?
The HS code for these mixtures is 3827.59, provided they do not contain CFCs or HCFCs.
Why are these mixtures in Chapter 38 instead of Chapter 29?
Chapter 29 is reserved for separate chemically defined compounds, whereas Chapter 38 covers chemical mixtures and preparations.
