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
