Import Tips

Verify cotton restraint quota availability via Cotton & Man-Made Fiber program before importing; obtain license if required

Provide lab test reports confirming <85% flax content and exact cotton/MMF percentages for CBP classification

Ensure fabric specs (weight, thread count) match poplin definition to avoid reclassification as sheeting or other plain weaves
