5402.69.01.00 - Other (606)

This HTS category, 5402.69.01.00, encompasses synthetic filament yarns that are not put up for retail sale. These yarns are characterized by being multiple (folded) or cabled, meaning two or more single strands are twisted together to form a stronger and more robust yarn. The "Other" designation signifies that these yarns are not primarily composed of nylon or other polyamides, nor are they made from polyesters or polypropylene, which are detailed in sibling categories.

To differentiate this category from its siblings, it is crucial to identify the dominant synthetic polymer. If a multiple or cabled yarn under 5402.6 is not predominantly nylon/polyamide (5402.61), polyester (5402.62), or polypropylene (5402.63), it falls into this residual "Other" classification. Examples could include yarns made from acrylic, modacrylic, or other synthetic fibers, provided they meet the other criteria of chapter 54, such as being filament yarns not put up for retail sale.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Classification at this level requires a thorough understanding of the material composition of the yarn and its construction as multiple or cabled. Customs professionals will need to verify the fiber content to ensure accurate classification and avoid misinterpretation with more specifically defined synthetic filament yarns.
