Import Tips

• Obtain proper hazardous material declarations (DOT/UN 1836) and ensure packaging meets UN standards for corrosive liquids

• Verify chemical purity certificates to confirm classification as chemically defined under Chapter 28 notes

• Avoid misclassification as organo-chlorine compounds; provide lab analysis if composition is questioned by customs
