Fine Denier Polyester Staple Fiber — China — A-570-060

“Fine Denier Polyester Staple Fiber” refers to a type of man-made fiber made from polyester and cut into short lengths. “Fine denier” describes the fiber’s fineness, while “staple fiber” distinguishes it from continuous filament. The legal product description, or scope, may also depend on physical characteristics, processing, and exclusions—not just the product name or tariff classification.

An AD/CVD measure combines antidumping (AD) and countervailing duty (CVD) rules. AD addresses imports sold at less than normal value, while CVD addresses benefits allegedly provided by a foreign government. These measures typically affect exporters, producers, manufacturers, and US importers of the covered product from specified countries. An importer may have to provide additional customs information, pay cash deposits at entry, and later face a different final duty liability after administrative review. The applicable scope and official case information control; an HTSUS number is useful for screening but does not by itself decide coverage.

What to check

• Compare the product’s fiber type, denier, length, finish, composition, and intended use with the official scope language, including listed exclusions.
• Confirm the country of origin and identify the actual foreign producer and exporter; AD/CVD treatment can vary by country and company.
• Check the relevant US government trade-remedy notices and the current AD/CVD instructions before entry, because deposit requirements and rates can change.
• Do not rely solely on the HTSUS classification or a supplier’s description; ask a customs broker or trade-remedy specialist to review uncertain products.
• Keep purchase records, technical specifications, origin evidence, and supplier certifications that support the product’s classification and scope analysis.
