Import Tips

• Verify fabric weight exceeds 360 g/m² via lab testing (ASTM D3776) and confirm denim definition compliance with 3/4-thread twill and color contrast

• Provide mill test certificate documenting >85% cotton content and yarn metrics (nm number per US notes); check origin quotas for cotton fabrics

• Avoid misclassification by ensuring no excessive sizing affects weight measurement—remove per US note formulas before testing
