Yarn of ≥85% Synthetic Staple Fibers (Not Sewing Thread), Packaged for Retail Sale

When a yarn blends two or more synthetic staple fibers (e.g., polyester and acrylic), all synthetic fiber weights are combined to determine whether the 85% threshold is met. The classification then depends on which single synthetic fiber predominates within that combined synthetic fraction.

The US eliminated most textile quotas after the WTO Agreement on Textiles and Clothing phase-out, but certain countries may still require textile visa documentation or certificates of origin depending on bilateral arrangements. Importers should check current CBP textile requirements and confirm origin documentation with their customs broker.
