Import Tips

Verify exact fiber content via lab testing to confirm <85% flax and presence of cotton/MMF for 5309.21.30 classification

Provide bleaching certification or unbleached declaration; ensure weave specs match Chapter 53 notes

Avoid misclassification as 100% cotton by documenting flax predominance in invoices
