HS code · 6-digit subheading
HS Code 5402.49 – Yarn, synthetic; filament, monofilament (less than 67 decitex), other than high tenacity or textured yarn, single, untwisted or twisted 50 turns or less per metre, n.e.c. in heading no. 5402, not for retail sale, not sewing thread
HS code 5402.49 is the 6-digit subheading for yarn, synthetic, filament, monofilament (less than 67 decitex), other than high tenacity or textured yarn, single, untwisted or twisted 50 turns or less per metre, n.e.c. in heading no. 5402, not for retail sale, not sewing thread. It is used for fine polyester monofilament yarn, fine nylon monofilament yarn, fine acrylic monofilament yarn, medical device synthetic yarn and filtration media synthetic yarn.
What HS 5402.49 covers
This HS code covers fine, single filament synthetic yarns (excluding polypropylene, high tenacity, or textured yarns) with a low decitex count (less than 67), indicating a very fine thread. These yarns are untwisted or minimally twisted (50 turns or less per meter), and are not intended for retail sale or as sewing thread. This 'not elsewhere specified' category captures a diverse range of fine synthetic monofilaments, such as those made from polyester, nylon, or acrylic, used in specialized industrial and textile manufacturing. Importers are typically manufacturers of technical fabrics, medical devices, filtration media, or specialized apparel components requiring fine, smooth synthetic filaments for their specific properties like strength, chemical resistance, or optical clarity. Exporters are large-scale synthetic yarn producers globally. Key trade considerations include the specific polymer type, the precise decitex, and the minimal twist, all of which dictate the yarn's suitability for highly specific, high-performance applications.

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 5402.49
What is HS code 540249?
HS code 540249 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, untwisted or twisted 50 turns or less per metre, n.e.c. in heading no. 5402, not for retail sale, not sewing thread. This HS code covers fine, single filament synthetic yarns (excluding polypropylene, high tenacity, or textured yarns) with a low decitex count (less than 67), indicating a very fine thread. These yarns are untwisted or minimally twisted (50 turns or less per meter), and are not intended for retail sale or as sewing thread. This 'not elsewhere specified' category captures a diverse range of fine synthetic monofilaments, such as those made from polyester, nylon, or acrylic, used in specialized industrial and textile manufacturing.
