HS code for High twist polyester yarn: 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.

Classification of high twist polyester yarn under HS 5402.52

Classification under HS code 5402.52 is determined by the material being a synthetic filament of polyester and the yarn being a single strand with a twist exceeding 50 turns per metre. This twist threshold is a defining characteristic that separates these yarns from low-twist or untwisted varieties. The yarn must be non-textured, meaning it has not been subjected to processes like air-jet or false-twist texturing to increase its volume. It also must not meet the definition of high tenacity yarn, which for polyester is defined as having a breaking tenacity greater than 42 cN/tex. The yarn must be intended for industrial use, as evidenced by being "not for retail sale." This classification is vital for the textile industry, particularly for manufacturers of smooth, high-density woven fabrics where the stability of a high-twist polyester filament is required without the bulk of textured yarns.

Codes often confused with 5402.52

Common mistake. The most common misclassification occurs with HS code 5402.33, which covers textured polyester yarns. If the yarn has been crimped or bulked, it belongs in 5402.33 regardless of the twist count. Additionally, 5402.20 is often mistakenly used; this code is specifically for high tenacity polyester yarn. If the yarn has a twist of 50 turns per metre or less, it falls under 5402.47. Importers must also ensure the yarn is not "multiple" or "cabled," which would move the classification to 5402.62.

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).
