Last updated: August 2026 dataHigh-tenacity viscose rayon filament yarn produces a woven fabric with greater tensile strength than standard rayon, making it a preferred substrate for industrial linings, technical apparel, and specialty apparel applications where drape and durability must coexist. This heading covers a single 10-digit tariff line (5408100000), reflecting its narrow, well-defined product scope within the broader artificial filament chapter. Italy and South Korea are leading suppliers to the US market, with Italy's position tied to its established luxury and technical textile manufacturing base. Importers should distinguish this heading from the broader 5408 subheadings covering standard viscose rayon and other artificial filaments, as the high-tenacity specification is the controlling classification criterion.

12 import shipments a month
High-tenacity viscose rayon yarn is produced through a modified spinning process that yields significantly higher breaking strength than conventional viscose rayon. For HTS classification, the yarn must meet the high-tenacity specification as defined in the HTS schedule notes; fabrics woven from standard viscose rayon filament yarn fall under the 5408.2x or 5408.3x subheadings rather than 5408.10.
Because the leading suppliers for this heading are Italy and South Korea rather than China, Section 301 List exposure is limited for typical import flows. However, importers sourcing from any origin should verify current tariff treatment with a licensed customs broker, as trade-remedy orders can change and country-of-origin rules for woven fabrics require careful review.
