HFC-32 Difluoromethane with Stabilizer Inhibitor from Germany
Difluoromethane containing a minimal polymerization inhibitor stabilizer is still classified under tariff item 2903.42.00, as Chapter 29 Note 1(f) permits added stabilizers necessary for preservation or transport. The stabilizer does not render the product particularly suitable for a specific use, so it remains a separate chemically defined organic compound. This product is correctly classified under 2903.42.00.

Import Tips
• Document the stabilizer's purpose and concentration to show it is solely for preservation or transport, as required by Chapter 29 Note 1(f)
• Ensure the stabilizer is not making the product suitable for a specific use, which could change classification
• Provide the SDS and a technical data sheet to the CBSA to support the classification
