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.

Products Included

  • Single polyester filament yarn with 75 turns per metre
  • Non-textured polyester yarn for industrial weaving
  • Single polyester monofilament (less than 67 decitex) with high twist
  • Polyester yarn on industrial cones for further processing

Common Misclassification

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.
