Fine Denier Polyester Staple Fiber — China — C-570-061

A US AD/CVD measure on Fine Denier Polyester Staple Fiber addresses imports of a particular type of man-made fiber. “AD” means antidumping duty, generally covering imports that Commerce determines are sold in the United States at less than fair value. “CVD” means countervailing duty, generally covering imports that benefit from government subsidies. These duties are separate from ordinary customs duty and may apply together.

The measure typically affects manufacturers, exporters, importers, and downstream businesses bringing the covered fiber into the United States. Coverage depends on the measure’s legal scope—such as the fiber’s physical characteristics, denier, composition, processing, and country of origin—not merely on a product description or an HTS classification. An importer may need to provide a required cash deposit at entry and could face additional liability when the entry is later reviewed. Customs and Border Protection (CBP) enforces collection, while the Department of Commerce administers the AD/CVD proceedings; a customs broker or trade counsel may be needed for a definitive scope analysis.

What to check

• Read the official scope language and compare the product’s material, denier, form, processing, and intended use; do not rely on the product name alone.
• Confirm the country of origin, manufacturer, and exporter, because AD/CVD treatment can vary by origin and company.
• Check the applicable HTS classification, but treat it as a screening tool rather than conclusive proof of scope.
• Ask your customs broker to verify entry documentation, cash-deposit instructions, and any required AD/CVD case information before importation.
• Keep product specifications, supplier certifications, purchase records, and origin documents in case CBP or Commerce requests support.
