HS Code 5402.11 – Yarn, synthetic; filament, monofilament (less than 67 decitex), of high tenacity yarn of nylon or other polyamides, textured or not; of aramids, not for retail sale, not sewing thread

HS code 5402.11 is the 6-digit subheading for yarn, synthetic, filament, monofilament (less than 67 decitex), of high tenacity yarn of nylon or other polyamides, textured or not, of aramids, not for retail sale, not sewing thread. It is used for aramid monofilament yarn, high-tenacity Kevlar yarn, nomex filament yarn, twaron monofilament and technora yarn.

What HS 5402.11 covers

This highly specific HS code targets high-tenacity synthetic filament yarn, specifically monofilament types with a linear density of less than 67 decitex, made from aramids (a class of polyamides). These yarns are characterized by exceptional strength-to-weight ratio, heat resistance, and chemical inertness, making them critical components in advanced industrial applications. They are explicitly "not for retail sale" and "not sewing thread," indicating their primary use as raw material in specialized manufacturing. Major importers are industries involved in aerospace, defense, protective equipment, and high-performance composites, seeking materials for demanding environments. Exporters are typically countries with advanced chemical and polymer manufacturing capabilities. Key trade factors include specific aramid type (e.g., Kevlar, Nomex), denier, tensile strength, modulus, and certifications for specific industrial standards. This niche market is driven by innovation in materials science and the need for extreme performance in critical applications.

Codes often confused with 5402.11

Common mistake. This code can be confused with 540219 (other high-tenacity polyamide yarns, non-aramid) due to the specific aramid distinction, or with 540231/540232 if the yarn is textured but not high-tenacity aramid.

Top exporters and importers of HS code 540211, 2025

In 2025, the largest exporter of HS code 540211 in UN Comtrade data was the Netherlands, with 32% of world exports; the largest importer in UN Comtrade data was the United States, with 11% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
