About HS Code 540231

This HS code identifies fine, textured synthetic filament yarn made from nylon or other polyamides, specifically those with a linear density of 50 decitex or less per single yarn. The "textured" aspect means the yarn has undergone a process to introduce crimp, loops, or other physical modifications, giving it bulk, stretch, and a softer feel, mimicking natural fibers. These yarns are not for retail sale directly to consumers and are not used as sewing thread, indicating their role as an industrial input. They are primarily traded between yarn manufacturers, textile mills, and apparel producers globally. Importers are typically textile factories producing hosiery, activewear, seamless garments, and fine knitwear, valuing the yarn's elasticity, strength, and comfort properties. Exporters are often large chemical and textile companies in Asia and Europe with advanced synthetic fiber production capabilities. Understanding the decitex measurement is crucial for proper classification, as it dictates the fineness and potential end-use of the yarn.

Products Under This Code

Fine denier nylon textured yarn, Polyamide microfilament yarn, Stretch nylon hosiery yarn, Textured polyamide yarn for seamless garments, Nylon 6.6 textured yarn, Fine gauge polyamide knitting yarn, Microfiber nylon yarn

Real World Examples

Invista (Lycra T400, though T400 is PBT/PET, Invista also makes nylon), Hyosung (Creora Nylon), RadiciGroup (Radilon), Nilit (Nilit Nylon 6.6), Ascend Performance Materials (Ascend Nylon)

Common Misclassification

This code is often confused with 540232 (textured polyamide yarn >50 decitex) due to similar material but different fineness, or with 540245 (non-textured polyamide yarn) if the texturing process is overlooked.
