Import Tips
• Document knitting gauges and silk waste ratios in technical specs to support classification claims
• Use HTS-specific labeling for 'men's silk underpants' to prevent gender misclassification under closure rules
• Watch for reclassification if elastic content exceeds norms, potentially shifting to other textile subheadings
