Import Tips
• Verify yarn number using HTS formula (e.g
• N = BYT/1,000) after removing sizing; fractions disregarded
• Provide lab test reports confirming <85% cotton content and exact weight per m² to avoid reclassification
• Ensure dyeing is uniform and documented; common pitfall is misstating yarn count leading to audits
