5402.48.00.10 - Monofilament; multifilament, untwisted or with twist of less than 5 turns per meter

This HTS subcategory, 5402.48.00.10, specifically covers monofilament and multifilament synthetic yarns, excluding sewing thread, that are not intended for retail sale. The key characteristic is their low twist, defined as less than 5 turns per meter. These yarns are composed entirely of polypropylene and are not bundled in a way suitable for immediate consumer use. Examples would include bulk unspun polypropylene fibers or yarns intended for industrial applications such as weaving into fabrics for industrial use, manufacturing ropes, or creating agricultural netting.

This classification distinguishes itself from its sibling, 5402.48.00.70, which covers "Other" polypropylene yarns not meeting the specific low-twist criteria or other specific definitions within the broader 5402 heading. While both fall under other yarns of polypropylene, this node is narrowly defined by its monofilament or multifilament structure and exceptionally low twist.

As this is a leaf node in the HTS, there are no further subcategories to introduce. Therefore, the focus remains on accurately identifying polypropylene yarns that meet the monofilament or low-twist multifilament criteria and are not put up for retail sale. Proper classification here relies heavily on verifying the material (polypropylene) and the physical characteristics of the yarn's twist.
