Import Tips

Classify as hazardous material (UN1789); require proper shipping papers, placards, and IMDG/49 CFR compliance

Verify concentration and purity via lab analysis to confirm Chapter 28 chemical definition; avoid misclassification as mixtures

Obtain EPA approvals if for water treatment use; common pitfall is inadequate corrosion-resistant packaging
