U.S. exports of Woven Fabrics of High-Tenacity Nylon, Polyamide, or Polyester Filament Yarn (HS 540710) totaled $10.2M in August 2026.
Importers of Woven Fabrics of High-Tenacity Nylon, Polyamide, or Polyester Filament Yarn paid $507K in duties in August 2026, an average duty rate of 20.53% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataHigh-tenacity nylon and polyester filament yarns — engineered for superior tensile strength rather than standard textile performance — produce woven fabrics used in ballistic protection, industrial belting, tire cord reinforcement, and technical outerwear. The US schedule distinguishes polyester constructions at or below 170 g/m² (5407100010) from heavier nylon and polyamide fabrics (5407100090), with weight-per-square-meter a key measurement at entry. Taiwan leads US supply, with India also a significant source; both countries have established technical textile weaving sectors serving defense and industrial end-users. Importers should verify whether specific end-uses — such as ballistic-resistant materials — trigger additional licensing or end-use certificate requirements.

High-tenacity yarn is defined in the HS nomenclature as yarn with a tenacity exceeding a specified breaking force relative to its linear density — generally above 60 cN/tex for nylon and polyester. Verification typically requires a manufacturer's test report citing tenacity values per standard methods (e.g., ASTM or ISO tensile testing). Without such documentation, CBP may reclassify the fabric under a standard filament yarn fabric heading.
The dividing line is 170 g/m²: polyester high-tenacity fabrics at or below this weight fall under 5407100010, while heavier nylon/polyamide fabrics fall under 5407100090. The distinction matters because the two lines may carry different duty rates, and misclassification based on an incorrect weight measurement is a common audit finding. Weight should be measured per square meter on the finished fabric, not estimated from yarn specifications.
