Last updated: August 2026 dataThe residual synthetic filament tow heading captures polymer types not covered by the specific aramid, polyamide, polyester, acrylic, or polypropylene subheadings — including specialty fibers such as polyvinyl alcohol, polyethylene, or other engineered polymers. Hungary leads US supply under this heading, followed by Mexico and Italy, a supplier mix that reflects niche production of specialty tow in European and North American facilities. Correct classification requires confirming that the fiber polymer does not belong to any of the named headings 550111–550140.

Polyvinyl alcohol (PVA), polyethylene, polylactic acid (PLA), and other specialty copolymer tows that do not meet the polymer definitions of aramid, polyamide, polyester, acrylic, or polypropylene are the most frequent candidates. Importers should obtain a detailed polymer composition certificate to support the NESOI classification and be prepared to justify why the product does not fall under a more specific subheading.
Mexico is a USMCA partner, and qualifying goods of Mexican origin may be eligible for preferential tariff treatment under USMCA, provided the product meets the applicable rules of origin. Importers should verify origin qualification with a licensed customs broker, as fiber inputs and processing steps affect whether the tow meets the textile-specific rule of origin.
