Import Tips
• Verify compliance with Montreal Protocol and EPA regulations on CFC imports, as production is globally phased out; obtain necessary exemptions or recycling certifications
• Provide detailed chemical purity analysis and SDS documentation to confirm it matches the exact subheading for dichlorotetrafluoroethane
• Avoid misclassification as mixtures; ensure product is chemically defined per Chapter 29 note (a) to prevent customs reclassification
