Product classification
HS code for Single artificial 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 single artificial yarn under HS 5403.39
Single artificial yarn is classified under HS code 5403.39. This classification is determined by the material composition and the physical structure of the yarn. Under Chapter 54, which covers man-made filaments, a distinction is made between synthetic filaments (polymers) and artificial filaments (regenerated cellulose). Artificial yarns include materials like viscose rayon, acetate, and triacetate. The term 'single' refers to a yarn consisting of one or more filaments that have not been twisted or plied with other yarns. Furthermore, 5403.39 is a residual category for artificial filament yarns that do not meet the specific criteria for high-tenacity yarn or other specialized subheadings within the 5403 group. To fall under this code, the yarn must not be put up for retail sale and must not be classified as sewing thread. The decitex of the monofilament must also be less than 67 decitex to remain within this heading; otherwise, it might be classified as a strip or similar form in heading 5405.

Codes often confused with 5403.39
Common mistake. This code is often confused with 5402.31, which covers synthetic filament yarns like nylon or polyester. The primary difference is the chemical origin of the fiber. It is also confused with 5403.10, which is specifically for high-tenacity yarns used in industrial applications like tire cord. Additionally, if the yarn is packaged for consumer use, it must be classified under 5406.00 for retail sale.
Top exporters and importers of HS 540339 (the code used for single artificial yarn), 2025
In 2025, the largest exporter of HS 540339 (the code used for single artificial 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.

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).
