Import Tips

Verify purity certification (typically 92-96%) as this determines classification under 2912.60; impure mixtures may shift to Chapter 38

Include Material Safety Data Sheets (MSDS) documenting formaldehyde content and polymerization structure for CBP review

Ensure proper Hazard Class 9 packaging and labeling per DOT/UN regulations for dangerous goods importation
