Import Tips

• Verify thermosetting nature via DSC testing to confirm no melt flow under heat, distinguishing from thermoplastics

• Provide monomer composition certificates showing 95%+ contribution to avoid reclassification under 'Other' per subheading note (a)(4)

• Ensure primary form (granules/powder) documentation; finished articles shift to Chapter 39 headings like 3920
