HS code for Artificial filament yarn: 5403.39

Yarn, artificial, filament, monofilament (less than 67 decitex), single, n.e.c. in heading no. 5403, not for retail sale, not sewing thread.

Classification of artificial filament yarn under HS 5403.39

This HS code, 540339, classifies artificial filament yarn that meets several specific criteria: it must be a single yarn, not for retail sale, not sewing thread, and specifically refers to monofilament with a linear density of less than 67 decitex, or other artificial filament yarns not elsewhere specified within heading 5403. The core elements for classification are "artificial filament yarn," indicating continuous man-made fibers derived from natural polymers (e.g., viscose rayon, acetate), and its form as a single yarn, as opposed to a multi-ply or cabled yarn. The exclusions (not for retail sale, not sewing thread) further refine its application to industrial or manufacturing uses, ensuring precise categorization within the Harmonized System.

Covers
  • Single viscose rayon filament yarn, industrial grade
  • Acetate monofilament yarn (less than 67 decitex) for technical textiles
  • Lyocell filament yarn, untwisted, for weaving applications
  • Artificial filament yarn for hosiery manufacturing, not put up for retail sale
  • Regenerated protein filament yarn, single, for industrial use
Also under 5403.39
  • Lenzing Modal Filament
  • Asahi Kasei Cupro
  • Tencel Lyocell Filament

Codes often confused with 5403.39

Common mistake. Common misclassifications for artificial filament yarn under 540339 include HS 540310 and HS 540341. HS 540310 covers "Artificial filament yarn, high tenacity, of viscose rayon." While also an artificial filament yarn, 540339 applies to yarns that do not meet the specific "high tenacity" criteria. If the yarn possesses high tenacity, it would fall under 540310. HS 540341, "Artificial filament yarn, multiple (folded) or cabled, of viscose rayon," is a misclassification because 540339 is specifically for "single" yarns, whereas 540341 covers yarns composed of two or more single yarns twisted together. Another potential error is confusing it with HS 540233, "Synthetic filament yarn, textured, of polyester, single, not for retail sale." This code is for synthetic filament yarn, not artificial filament yarn, and also specifies "textured" yarn, which is a distinct characteristic. Finally, HS 540600, "Artificial filament yarn, put up for retail sale," is a misclassification as 540339 explicitly excludes yarn "not for retail sale," focusing on industrial-grade products.

Top exporters and importers of HS 540339 (the code used for artificial filament yarn), 2025

In 2025, the largest exporter of HS 540339 (the code used for artificial filament yarn) in UN Comtrade data was Japan, with 73% of world exports; the largest importer in UN Comtrade data was China, with 41% 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. UN Comtrade records Taiwan as "Other Asia, not elsewhere specified". Saudi Arabia's exports under that code are left out: they are far too large to be trade with Taiwan, so mostly undisclosed partners. 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 artificial filament yarn

What is the HS code for Artificial filament yarn?

The HS code for Artificial filament yarn is 540339 (Yarn, artificial; filament, monofilament (less than 67 decitex), single, n.e.c. in heading no. 5403, not for retail sale, not sewing thread).

How do I classify Artificial filament yarn for customs?

Artificial filament yarn is classified under HS code 540339 — Yarn, artificial; filament, monofilament (less than 67 decitex), single, n.e.c. in heading no. 5403, not for retail sale, not sewing thread. This is a 6-digit subheading level code.

What is the HS code for Artificial filament yarn (single, industrial use)?

The HS code for artificial filament yarn that is single, not for retail sale, not sewing thread, and includes monofilament less than 67 decitex or other yarns not elsewhere specified in 5403, is 540339. This code is intended for industrial applications of such yarns.

What does "decitex" refer to in yarn classification?

Decitex (dtex) is a unit of linear density used for fibers and yarns, representing the weight in grams of 10,000 meters of yarn. A lower decitex value indicates a finer yarn. In HS classification, specific decitex thresholds are often used to differentiate between various types of monofilament and multifilament yarns, influencing their precise categorization.

Which countries are the top exporters of artificial filament yarn (HS 540339)?

In 2025, the top exporters of HS 540339 (the code used for artificial filament yarn) in UN Comtrade data were Japan ($115M, 73% of world exports), China ($21M) and Taiwan (about $17M). World exports came to about $158M, 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.
