Import Tips
• Include TSCA certification; HFC-143a requires pre-manufacture notice if new uses exceed reporting thresholds
• Verify container pressure ratings meet DOT 49 CFR for UN1950 aerosols; include filling documentation
• Prevent reclassification as finished aerosol product (HTS 8424) by importing chemical only, not assembled cans
