HS code for High twist synthetic yarn: 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.

Classification of high twist synthetic yarn under HS 5402.59

HS code 5402.59 is a residual category for single synthetic filament yarns that are not made of nylon, polyester, or polypropylene. This includes yarns made from polymers such as acrylic, modacrylic, or certain elastomeric fibers, provided they are single yarns with a twist exceeding 50 turns per metre. The yarn must be non-textured and not high tenacity. This classification is used for specialized synthetic fibers that do not have their own specific subheadings within the 5402.5x group. The yarn must be intended for industrial or manufacturing use and not be packaged for retail sale. It is also distinguished from artificial fibers, which are derived from natural polymers and classified under heading 5403. The technical requirement of more than 50 turns per metre ensures that these yarns are distinguished from the more common low-twist or untwisted "other" synthetic filaments.

Covers
  • Single acrylic filament yarn with 70 turns per metre
  • Single modacrylic filament yarn with high twist
  • Non-textured synthetic yarns (other than nylon/polyester/PP) with >50 turns/m
  • Specialty synthetic filaments for industrial use
Also under 5402.59
  • Dralon acrylic yarn
  • Kaneka modacrylic fiber
  • Mitsubishi Chemical specialty yarn
  • Torayca (carbon fiber precursor, though this is more general synthetic)

Codes often confused with 5402.59

Common mistake. This code is often confused with 5402.49, which covers "other" synthetic yarns with a twist of 50 turns per metre or less. It is also frequently confused with 5402.39, which is for textured "other" synthetic yarns. Importers must also be careful not to use this code for artificial yarns like viscose or acetate, which belong in heading 5403. If the yarn is a blend of different synthetic fibers, classification is determined by the fiber that predominates by weight, according to Section XI, Note 2.

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).
