5406.00.10.90 - Other (200)

This HTS category, 5406.00.10.90, encompasses man-made filament yarn, excluding sewing thread, when it is packaged and presented for retail sale. Specifically, it covers synthetic filament yarn that does not fall under the more precisely defined categories within the same heading. This "other" designation applies to synthetic filament yarns made from materials not otherwise specified in the subheading, such as nylon or other synthetic polymers.

In contrast to sibling categories such as 5406.00.10.20 (Of acrylic) and 5406.00.10.40 (Of polyesters), this classification serves as a residual category. Goods classified here are synthetic filament yarns that are not primarily composed of acrylic or polyester. Therefore, the key distinguishing factor for classification into this subheading is the material composition of the synthetic filament yarn.

As a leaf node, 5406.00.10.90 has no further subcategories. Classification within this code requires a thorough understanding of the synthetic filament yarn's material composition to ensure it is not specifically accounted for under other subheadings within 5406.00.10. The yarn must be of the filament type (as opposed to staple fiber yarn), intended for retail sale, and made from a synthetic material other than acrylic or polyester to warrant classification here.
