Import Tips & Compliance
• Verify fiber content is over 85% artificial fibers like polyester via lab tests to confirm Chapter 60 classification
• Provide mill construction certificates proving double knit or interlock (222) to avoid reclassification to other 6006 subheadings
• Declare exact bleach status; unbleached/bleached distinction affects duty rates and requires clean invoices
