Product classification
HS code for polyamide filament yarn: 5402.19
Yarn, synthetic, filament, monofilament (less than 67 decitex), of high tenacity nylon or other polyamides, textured or not, other than aramids, not for retail sale, not sewing thread.
Classification of polyamide filament yarn under HS 5402.19
The classification of polyamide filament yarn under HS code 5402.19 is determined by its chemical composition, physical structure, and mechanical properties. Chapter 54 of the Harmonized System covers man-made filaments, and heading 5402 specifically addresses synthetic filament yarn that is not prepared for retail sale and is not sewing thread. Within this heading, the 5402.19 subheading is reserved for high tenacity yarns made of nylon or other polyamides, excluding aramid fibers. High tenacity is a technical designation defined by the yarn's breaking tenacity, which must typically exceed 60 centinewtons per tex. This classification is critical for industrial-grade yarns used in heavy-duty applications where strength and durability are paramount. The yarn must be in the form of filaments (continuous strands) rather than staple fibers to remain within Chapter 54. Furthermore, the exclusion of aramids (which fall under 5402.11) and the requirement that the yarn is not for retail sale (which would move it to 5406) are the primary boundary conditions for this specific code.

Codes often confused with 5402.19
Common mistake. This code is frequently confused with HS code 5402.11, which is specifically for high tenacity yarn of aramids such as Kevlar or Nomex. While aramids are chemically polyamides, the HS system separates them due to their unique heat-resistant properties. Another common error is using 5401.10, which is reserved for sewing thread; if the yarn is finished or lubricated for use as thread, it must be moved to 5401. Additionally, if the yarn is textured (crimped), it may fall under 5402.31, provided it does not meet the high tenacity threshold.
Top exporters and importers of HS 540219 (the code used for polyamide filament yarn), 2025
In 2025, the largest exporter of HS 540219 (the code used for polyamide filament yarn) in UN Comtrade data was China, with 33% of world exports; the largest importer in UN Comtrade data was Thailand, with 8.2% 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 marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).

Questions about polyamide filament yarn
What is the HS code for polyamide filament yarn?
The HS code for polyamide filament yarn is 540219 (Yarn, synthetic; filament, monofilament (less than 67 decitex), of high tenacity nylon or other polyamides, textured or not; other than aramids, not for retail sale, not sewing thread). The HS code for high tenacity polyamide filament yarn (excluding aramids and not for retail sale) is 5402.19.
How do I classify polyamide filament yarn for customs?
polyamide filament yarn is classified under HS code 540219 — Yarn, synthetic; filament, monofilament (less than 67 decitex), of high tenacity nylon or other polyamides, textured or not; other than aramids, not for retail sale, not sewing thread. This is a 6-digit subheading level code.
How is high tenacity defined for this classification?
Under the Harmonized System, high tenacity for nylon or other polyamides is generally defined as having a breaking tenacity greater than 60 cN/tex.
Which countries are the top exporters of polyamide filament yarn (HS 540219)?
In 2025, the top exporters of HS 540219 (the code used for polyamide filament yarn) in UN Comtrade data were China ($405M, 33% of world exports), Japan ($131M) and Vietnam (about $120M). World exports came to about $1.2B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of polyamide filament yarn (HS 540219)?
