Last updated: July 2026 dataPolyester staple fiber (PSF) in its unprocessed form is one of the most widely traded synthetic fiber commodities globally, feeding into filling materials, nonwovens, and blended yarn production. Because PSF is derived from PET — itself linked to recycled PET (rPET) supply chains — buyers increasingly specify virgin versus recycled fiber grades, a distinction that affects both pricing and sustainability certifications. Trade flows for this commodity have been subject to antidumping scrutiny from multiple source countries, making admissibility review and country-of-origin verification essential for US importers.

The US has maintained antidumping duty orders on polyester staple fiber from several countries. Importers must check the current scope of active orders with CBP and the Department of Commerce, as covered merchandise requires cash deposits at the applicable antidumping rate and may be subject to administrative review.
Both virgin and recycled (rPET-derived) polyester staple fibers can fall under this heading provided they are not carded, combed, or otherwise processed for spinning. The distinction matters commercially — buyers in sustainable textile supply chains require documentation of recycled content — but it does not by itself change the SITC classification.
