U.S. exports of high tenacity aramid filament yarn (HS 540211) totaled $10.9M in July 2026.
Importers of High Tenacity Aramid Filament Yarn paid $1.1M in duties in July 2026 — an effective duty rate of 17% on $6.9M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataAramid-based high tenacity yarn — including para-aramid fibers such as Kevlar and Twaron — is a critical input for ballistic protection, aerospace composites, and industrial reinforcement applications. The US tariff schedule subdivides this heading by twist level and decitex count, with lines 5402113010 through 5402116000 distinguishing monofilament versus multifilament constructions and low-twist versus higher-twist configurations. The Netherlands and South Korea are the leading suppliers, reflecting the concentrated global production base for para-aramid fiber. Importers should note that certain aramid yarns destined for defense end-uses may be subject to export controls in the country of origin, adding a compliance layer beyond standard customs entry.

The schedule breaks out lines by twist level (untwisted or less than 5 turns per meter versus 5 turns or more) and by decitex threshold (at or below 920 decitex versus above 920 decitex), as well as separating single/monofilament from multiple or cabled constructions. Correct classification requires knowing the yarn's twist count, linear density, and filament count before entry.
Aramid yarn imports have historically attracted antidumping scrutiny in various markets; US importers should verify current antidumping or countervailing duty orders with CBP and consult a licensed customs broker, as orders can be initiated, revoked, or modified between publication cycles.
