Import Tips

• Provide Certificate of Analysis (CoA) confirming aromatic cyclic amide structure and purity >98% to verify classification under 2924.21.4500

• Declare exact CAS number and avoid mixing with solvents that alter 'general use' per Chapter 29 note (e)

• Check REACH/ TSCA pre-registration; common pitfall is misclassifying as polymer if molecular weight exceeds limits
