Import Tips
• Include flame-retardancy test reports if marketing as such, but ensure classification remains fabric-only without assembly
• Document bleaching process to distinguish from unbleached; customs may require swatches for color verification
• Watch for over-classification as finished goods—import in bolts to avoid apparel or upholstery headings
