Import Tips & Compliance

Verify certificate of analysis confirming aromatic hydrocarbon derivation to meet HTS 2917.14.10.00 specificity

Ensure proper UN packaging (Group II corrosive) and include Material Safety Data Sheets (MSDS)

Avoid misclassification as petroleum-derived (2917.14.20.00) which has different duty rates
