HS Code 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
HS code 5402.39 is the 6-digit subheading for 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. It is used for textured Acrylic Filament Yarn, textured Modacrylic Yarn, textured Polyurethane Filament Yarn, specialty Textured Synthetic Yarn and textured Aramid Yarn (fine denier).
What HS 5402.39 covers
This category encompasses fine, textured synthetic filament yarns (under 67 decitex) made from polymers *other than* nylon, polyesters, or polypropylene, and not intended for retail or as sewing thread. This "other" category is important for specialized applications where unique properties are required, often involving advanced polymers. Importers are typically niche textile manufacturers, high-performance material producers, and innovators in technical textiles, found in developed economies like Japan, Germany, and the USA, seeking specific functionalities. Exporters are often specialized chemical companies and advanced material manufacturers, primarily from countries with strong R&D capabilities in polymer science, such as Japan, Germany, and the USA, as well as some emerging Asian economies. Key aspects include the "textured" nature for bulk and comfort, the "less than 67 decitex" for fineness, and the exclusion of common polymers, indicating a focus on specialty synthetic fibers like acrylics, modacrylics, or elastomeric blends (if not specifically covered elsewhere). This code highlights the diversity and innovation within the synthetic yarn market beyond the major commodity fibers.

Codes often confused with 5402.39
Common mistake. This code is often confused with 540233 (polyester) or 540234 (polypropylene) if the specific polymer type is not clearly identified, or with 540249 if the yarn is not textured.
Top exporters and importers of HS code 540239, 2025
In 2025, the largest exporter of HS code 540239 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).

What are common misclassifications for HS code 540239?
This code is often confused with 540233 (polyester) or 540234 (polypropylene) if the specific polymer type is not clearly identified, or with 540249 if the yarn is not textured.
Which countries are the top exporters of goods under HS code 540239?
In 2025, the top exporters of HS code 540239 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.
