HS code · 6-digit subheading
HS Code 5402.59 – Yarn, synthetic; filament, monofilament (less than 67 decitex), other than high tenacity or textured yarn, single, twisted more than 50 turns per metre, n.e.c. in heading no. 5402, not for retail sale, not sewing thread
HS code 5402.59 is the 6-digit subheading for yarn, synthetic, filament, monofilament (less than 67 decitex), other than high tenacity or textured yarn, single, twisted more than 50 turns per metre, n.e.c. in heading no. 5402, not for retail sale, not sewing thread. It is used for fine acrylic weaving yarn, modacrylic filament yarn, specialty synthetic knitting yarn, technical synthetic monofilament and industrial acrylic yarn.
What HS 5402.59 covers
This "n.e.c." (not elsewhere classified) code captures fine, single filament synthetic yarns that don't fit into the specific polyester (540252) or polypropylene (540253) categories, but still meet the criteria of being less than 67 decitex, highly twisted (over 50 turns/meter), and not high tenacity or textured. This typically includes yarns made from acrylic, modacrylic, or other less common synthetic polymers. These specialized yarns are traded internationally as industrial inputs, not for direct consumer sale or as sewing thread. Importers are often niche textile manufacturers or technical fabric producers in developed economies like the EU and North America, seeking specific properties for advanced applications. Exporters are usually specialized chemical and textile companies, often from Asia or Europe, capable of producing these diverse synthetic fibers. The key challenge in trade for this code is correctly identifying the specific polymer type to ensure accurate classification, as it's a residual category for fine, highly twisted, non-textured, non-high tenacity synthetic filament yarns.

Codes often confused with 5402.59
Common mistake. This code is often confused with 540252 (polyester) or 540253 (polypropylene) if the specific polymer type is not correctly identified, or with other "n.e.c." codes for different yarn types like 540249 (textured) or 540239 (high tenacity).
Top exporters and importers of HS code 540259, 2025
In 2025, the largest exporter of HS code 540259 in UN Comtrade data was China, with 36% of world exports; the largest importer in UN Comtrade data was China, with 25% 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 that did not report are estimated from what other countries recorded trading with them. 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 HS 5402.59
What is HS code 540259?
HS code 540259 is a 6-digit subheading in the Harmonized System that covers: Yarn, synthetic; filament, monofilament (less than 67 decitex), other than high tenacity or textured yarn, single, twisted more than 50 turns per metre, n.e.c. in heading no. 5402, not for retail sale, not sewing thread.

What products fall under HS code 540259?
Fine acrylic weaving yarn, modacrylic filament yarn, specialty synthetic knitting yarn, technical synthetic monofilament, industrial acrylic yarn, other synthetic apparel yarn
What are common misclassifications for HS code 540259?
This code is often confused with 540252 (polyester) or 540253 (polypropylene) if the specific polymer type is not correctly identified, or with other "n.e.c." codes for different yarn types like 540249 (textured) or 540239 (high tenacity).
Which countries are the top exporters of goods under HS code 540259?
In 2025, the top exporters of HS code 540259 in UN Comtrade data were China ($24M, 36% of world exports), Japan ($11M) and the Netherlands ($8.8M). World exports came to about $67M, 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.
