Last updated: April 2026 dataViscose rayon tow and other regenerated cellulosic filament tows not made from cellulose acetate fall under this residual heading, classified at the 10-digit level under 5502900000. Germany leads US supply, with the Dominican Republic and Turkey rounding out the top three sources — a geographically diverse supplier base reflecting specialty rayon production in Europe and emerging textile economies. Correct classification hinges on confirming the fiber is regenerated from a natural polymer (e.g., viscose, cuprammonium, or lyocell precursor tow) rather than a synthetic one.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Lyocell is a regenerated cellulosic fiber produced via a solvent-spinning process, and when presented as filament tow it would generally be classified under 5502900000 as an artificial filament tow other than cellulose acetate. Importers should confirm the specific form (tow versus staple) and polymer origin with their customs broker, as the presentation and processing stage affect the correct heading.
The Dominican Republic's presence among top suppliers likely reflects processing or re-export activity tied to its textile manufacturing sector rather than primary fiber production. Importers sourcing from the Dominican Republic should verify origin documentation carefully to ensure the product meets applicable rules of origin, particularly if claiming any preferential tariff treatment.
