U.S. imports of High-Tenacity Viscose Rayon Yarn (Non-Sewing Thread, Bulk) (SITC 65173) totaled $299K in August 2026, imported from 5 countries.
Importers of High-Tenacity Viscose Rayon Yarn (Non-Sewing Thread, Bulk) paid $30K in duties in August 2026, an average duty rate of 10.00% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. High-Tenacity Viscose Rayon Yarn (Non-Sewing Thread, Bulk) imports of $299K in August 2026 ran 36% below the year-to-date monthly average of $464K.
Last updated: August 2026 dataHigh-tenacity viscose rayon yarn is an engineered form of regenerated cellulose filament, processed to achieve breaking tenacity levels suitable for tire cord, conveyor belt reinforcement, and industrial hose — end uses where standard textile-grade rayon would fail under load. Unlike synthetic high-tenacity yarns (covered under 65162), this product's cellulosic origin places it in the artificial filament yarn family, a distinction that affects both classification and the applicable duty rate. The 'high tenacity' designation must be supported by tensile test data, as the threshold is defined in the tariff schedule notes and is subject to verification.

Viscose rayon is a regenerated cellulosic fiber — derived from wood pulp or cotton linters — while synthetic fibers such as nylon and polyester are petroleum-derived. This fundamental fiber-origin distinction places them in different sections of both the SITC and HTS schedules, with different duty rates and potentially different trade-remedy exposure. Importers must correctly identify fiber origin (artificial vs. synthetic) on entry documents, supported by the manufacturer's fiber composition certificate.
The dominant end-use is tire cord fabric, where high-tenacity rayon's combination of heat resistance, dimensional stability, and adhesion to rubber compounds makes it competitive with polyester and aramid alternatives in certain tire categories. Conveyor belts and industrial hose reinforcement are secondary markets. Because these are capital-intensive industries with long qualification cycles, supply disruptions — whether from trade-remedy actions, mill capacity changes, or logistics issues — can have outsized downstream consequences, making supply-chain diversification a strategic priority for procurement teams.
