5402.63.00.00 - Of polypropylene (606)

This HTS category, 5402.63.00.00, specifically covers multiple (folded) or cabled yarns made from polypropylene. These are synthetic filament yarns, not intended for retail sale, and exclude synthetic monofilaments with a decitex of less than 67. The critical defining characteristic for this classification is the material: 100% polypropylene.

This classification is distinct from its siblings by its material composition. 5402.61.00.00 pertains to yarns of nylon or other polyamides, while 5402.62.00.00 applies to yarns of polyesters. Therefore, any multiple or cabled synthetic filament yarn that is not of nylon, polyamide, or polyester, but is instead made from polypropylene, falls under this specific code.

As this is a leaf node, there are no further subdivisions within this category. Classification decisions at this level rely solely on confirming the yarn is a multiple (folded) or cabled synthetic filament yarn, not for retail sale, and is exclusively composed of polypropylene. Examples would include tightly twisted yarns of polypropylene filaments used in industrial applications such as rope making, carpet backing, or industrial sewing where strength and durability are paramount.
