Import Tips & Compliance
• Verify yarn number and ply count via lab testing to confirm classification under 'other yarn' excluding multiples
• Provide mill certificates showing artificial staple fiber composition (e.g
• viscose, acetate) for customs clearance
• Avoid retail packaging; ship in cones or beams to qualify as not put up for retail sale and prevent misclassification
