About HS Code 540249

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.

Products Under This Code

Fine polyester monofilament yarn, fine nylon monofilament yarn, fine acrylic monofilament yarn, medical device synthetic yarn, filtration media synthetic yarn, specialized technical fabric yarn, fine aramid monofilament yarn.

Real World Examples

DuPont (nylon yarns), Teijin (polyester yarns), Lenzing (specialty fibers), BASF (various polymers), Mitsubishi Chemical.

Common Misclassification

Frequently confused with 540248 (polypropylene monofilament) if the specific polymer is not identified, or with 540251 (nylon/polyamide twisted yarn) if the twist level is misjudged.
