5402.52.90.00 - Other (606)

This HTS category, 5402.52.90.00, encompasses "Other" synthetic filament yarns, specifically those not put up for retail sale and not meeting the specific criteria of other subcategories within the polyester filament yarn classification. These yarns are single, meaning they consist of a single strand of filament, and have a twist exceeding 50 turns per meter. The core material is polyester, and the classification applies to yarns that do not fall into more precisely defined groups based on decitex and filament count.

This category serves as a residual classification for polyester filament yarns of this nature. Its key differentiator from the sibling category, 5402.52.10.00, lies in the absence of the specific specifications for decitex (between 75 and 80) and filament count (24 filaments per yarn). Therefore, any polyester filament yarn that is single, has a twist exceeding 50 turns/m, is not for retail sale, and does not meet the precise decitex and filament count criteria of the sibling category will be classified here.

As this is a leaf node, there are no further subcategories. The classification here is final for eligible goods. Examples of yarns that would fall under this heading include polyester filament yarns with a decitex significantly lower or higher than the 75-80 range, or those with a different filament count than 24, provided they are single, twisted over 50 turns/m, and not packaged for retail sale. The "Other" designation highlights its role in capturing polyester filament yarns that do not fit more narrowly defined subheadings.
