Import Tips

• Verify exact flax content (<85%) and cotton/man-made percentages via lab testing to confirm 5309 classification and cotton restraint applicability

• Provide mill test certificates documenting fiber composition, weave type (poplin), and weight to avoid reclassification during customs exam

• Monitor US cotton restraint quotas; obtain necessary licenses if applicable and watch for over-quota surcharges
