Import Tips
• Verify silk content certification with lab tests exceeding 70% to avoid reclassification to lower silk categories
• Label products clearly as 'men's' with left-over-right closure to comply with Chapter 61 gender classification rules
• Include mill certificates for silk waste to prevent undervaluation claims during customs valuation
