Import Tips & Compliance
• Include mill certificates specifying exact silk waste percentage and garnetting process to support the 85% threshold claim
• Avoid fugitive dyes that don't wash out completely, as they may classify the yarn as 'colored' under subheading definitions
• For multiple-ply yarns, document each component's silk content to confirm overall composition meets silk waste dominance
