Import Tips
• Verify polyurethane monomer content exceeds 95% by weight via lab testing to meet subheading note (a)(1); provide supplier certificates of analysis
• Common pitfall: misclassifying as finished sealant under 3214 if over 50% solvent
• Declare as 'primary form' to avoid parts classification
