HS Code 5402.52 – Yarn, synthetic; filament, monofilament (less than 67 decitex), of polyesters (not high tenacity or textured), single, twisted more than 50 turns per metre, not for retail sale, not sewing thread
HS code 5402.52 is the 6-digit subheading for yarn, synthetic, filament, monofilament (less than 67 decitex), of polyesters (not high tenacity or textured), single, twisted more than 50 turns per metre, not for retail sale, not sewing thread. It is used for fine polyester weaving yarn, high-twist polyester knitting yarn, polyester embroidery base yarn, technical textile polyester yarn and apparel grade polyester yarn.
What HS 5402.52 covers
This code covers fine, single polyester filament yarns, specifically those with a low decitex count (less than 67), indicating a very fine thread. These yarns are characterized by a high twist (over 50 turns per meter) and are not designed for direct retail sale or as sewing thread. In international trade, these specialized yarns are crucial intermediate goods for textile manufacturers. Major importers are often countries with robust textile and apparel industries, such as Vietnam, Bangladesh, and Turkey, which process these yarns into fabrics. Exporters typically include large chemical and textile producers in China, India, and Taiwan, where the raw materials and manufacturing capabilities are abundant. Key things to know include the importance of twist level for fabric properties like strength and drape, and the "not for retail sale" clause, which distinguishes it from consumer-ready products. The fineness (decitex) also dictates its suitability for lightweight and delicate fabrics.

Codes often confused with 5402.52
Common mistake. This code can be confused with 540233 (high tenacity polyester yarn) or 540247 (textured polyester yarn) if the specific properties of tenacity or texturing are overlooked. It's also distinct from 540251 which has a lower twist.
Top exporters and importers of HS code 540252, 2025
In 2025, the largest exporter of HS code 540252 in UN Comtrade data was China, with 53% of world exports; the largest importer in UN Comtrade data was Germany, with 8.1% of world imports. Vietnam did not report 2025 data, and its estimate from partner records misses its trade with other countries that did not report: in 2024 that was 6.8% of its imports here ($891K, CEPII BACI), so it may rank higher.

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).
