Import Tips
• Certify flame-retardant impregnation specs to prove 'other than plastics' and avoid Chapter 39/40 shifts
• Declare end-use as automotive if applicable, but note classification is material-based, not use-based
• Test for visible coating per chapter notes; naked-eye undetectable moves to yarn headings
