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
