Import Tips

Verify chemical purity and provide Safety Data Sheets (SDS) compliant with OSHA and EPA for hazardous material declaration

Ensure proper UN packaging and labeling as a corrosive substance (UN1836) to avoid customs delays

Confirm no organo-inorganic impurities, as those shift to Chapter 29; include lab analysis certificates
