Import Tips

Verify exact fiber content via lab test; must be <85% cotton mixed mainly with MMF to qualify

Provide weave certification confirming 3- or 4-thread twill; weight must not exceed 200 g/m² post-scouring

Avoid misclassification as 100% cotton (5208) by including MMF blend invoices and mill certificates
