Product classification
HS code for Synthetic filament yarn (textured): 5402.39
Yarn, synthetic, filament, monofilament (less than 67 decitex), textured, other than of nylon or other polymides, polyesters, or polypropylene, not for retail sale, not sewing thread.
Classification of synthetic filament yarn (textured) under HS 5402.39
Textured synthetic filament yarn is classified under HS code 5402.39. This is a residual category for 'other' textured yarns that do not consist of nylon (polyamides), polyesters, or polypropylene. Texturing is a mechanical or chemical process—such as twisting, crimping, or air-jetting—that transforms flat filaments into yarns with greater volume, elasticity, and a softer hand-feel. Under Chapter 54, the yarn must be a synthetic filament (not staple fiber) and must not be put up for retail sale. The classification 5402.39 is used for specialized polymers like acrylic or modacrylic filaments that have been textured. The technical distinction between textured and non-textured yarn is vital; textured yarns have physical distortions in the filaments that do not disappear under low tension, providing the bulk necessary for specific knitting and weaving applications in the garment industry.

Codes often confused with 5402.39
Common mistake. The most common error is classifying these yarns under 5402.31 (nylon) or 5402.33 (polyester). Because polyester and nylon dominate the market, 5402.39 is often overlooked. Another misclassification is 5402.44, which is for elastomeric yarns; while both have stretch, textured yarns achieve elasticity through physical shape rather than the chemical nature of the polymer. If the yarn is made of staple fibers, it must be moved to Chapter 55.
Top exporters and importers of HS 540239 (the code used for synthetic filament yarn (textured)), 2025
In 2025, the largest exporter of HS 540239 (the code used for synthetic filament yarn (textured)) in UN Comtrade data was China, with 50% of world exports; the largest importer in UN Comtrade data was the Netherlands, with 10% 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 synthetic filament yarn (textured)
What is the HS code for Synthetic filament yarn (textured)?
The HS code for Synthetic filament yarn (textured) is 540239 (Yarn, synthetic; filament, monofilament (less than 67 decitex), textured, other than of nylon or other polymides, polyesters, or polypropylene, not for retail sale, not sewing thread).
How do I classify Synthetic filament yarn (textured) for customs?
Synthetic filament yarn (textured) is classified under HS code 540239 — Yarn, synthetic; filament, monofilament (less than 67 decitex), textured, other than of nylon or other polymides, polyesters, or polypropylene, not for retail sale, not sewing thread. This is a 6-digit subheading level code.
What is the HS code for textured synthetic yarn?
For textured synthetic filament yarns other than nylon, polyester, or polypropylene, the HS code is 5402.39.
What does 'textured' mean in HS classification?
It refers to yarn that has been processed to have curls, crimps, or loops, increasing its volume and giving it a 'spun' appearance despite being a continuous filament.
Which countries are the top exporters of synthetic filament yarn (textured) (HS 540239)?
In 2025, the top exporters of HS 540239 (the code used for synthetic filament yarn (textured)) in UN Comtrade data were China ($29M, 50% of world exports), Thailand ($6.7M) and India ($6.2M). World exports came to about $58M, 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 synthetic filament yarn (textured) (HS 540239)?
