U.S. imports of High Tenacity Nylon & Polyamide Filament Yarn (Non-Aramid) (HS 540219) totaled $6.9M in August 2026, imported from 21 countries.
Importers of High Tenacity Nylon & Polyamide Filament Yarn (Non-Aramid) paid $439K in duties in August 2026, an average duty rate of 6.41% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataNon-aramid high tenacity nylon and polyamide yarns serve as load-bearing inputs in tire cord, conveyor belting, parachute fabric, and technical webbing — applications where tensile strength per unit weight is the primary specification. Canada leads US supply under this heading, with China and Colombia also significant sources. The US schedule mirrors the aramid heading's structure, splitting lines 5402193010 through 5402196000 by twist count and decitex, so a misclassification between this heading and the aramid heading (540211) can arise when polyamide blends contain trace aramid content.

217 import shipments a month
Heading 540211 covers high tenacity yarn specifically of aramids (e.g., para-aramid or meta-aramid polymers), while 540219 covers all other nylon or polyamide high tenacity yarns. If a yarn is made from a polyamide that does not meet the chemical definition of an aramid, it falls under 540219 regardless of its strength characteristics.
Synthetic filament yarns from China may be subject to Section 301 tariffs. Importers should confirm the applicable Section 301 list and any exclusions in effect at the time of entry with a licensed customs broker, as coverage and exclusion status change periodically.
