Import Tips
• Classify the product as a roving, not a yarn, since it is a single-end continuous strand
• Maintain records of the linear density and filament diameter to support the tariff classification
• If the roving is impregnated with resin, check if it falls under a different heading, as pre-impregnated materials may be excluded
