Import Tips
• Verify purity and chemical composition via lab analysis to confirm classification as chemically defined under Chapter 28 notes
• Include Material Safety Data Sheets (MSDS) and ensure UN-approved packaging for corrosive inorganic fluorides
• Avoid misclassification as organo-inorganic compounds, which fall outside Chapter 28 per note exclusions
