CFC-114 Blowing Agent for Polyurethane Foam from Mexico
CFC-114 serves as a blowing agent in rigid polyurethane foam production, fitting HTS 2903.77.00.30 due to its status as a separate chemically defined perhalogenated acyclic hydrocarbon with fluorine and chlorine only. This classification adheres to Chapter 29's scope for halogenated derivatives. It was commonly used in insulation foams before phase-out.

Import Tips
• Include end-use declarations for foam production to support classification and comply with environmental import quotas on ozone-depleting substances
• Ensure packaging meets UN standards for compressed gases; improper labeling leads to hazardous material surcharges
• Check for stabilizer additions; per Chapter 29 note (f), stabilizers for transport do not change classification if necessary for preservation
