Import Tips & Compliance

Verify decitex measurement (<67 dtex) and twist (<5 turns/m) via lab testing to confirm HTS 5402.45.90.30 classification

Provide manufacturer's yarn specifications and end-use declaration to avoid misclassification as sewing thread (5404)

Ensure not put up for retail sale (e.g

no consumer packaging) to prevent shift to higher-duty retail codes
