Import Tips
• Provide Certificate of Analysis confirming purity >99% and absence of impurities to verify chemical identity under Chapter 29 note (a)
• Ensure proper UN 2924 hazardous material labeling and shipping papers for flammable liquid Class 3
• Avoid misclassification as mixtures; pure THF qualifies, but solvent blends may shift to Chapter 38
