5404.12 - Other, of polypropylene:

This HTS category, 5404.12, "Other, of polypropylene," specifically covers synthetic monofilaments or strips made from polypropylene that meet certain dimensional criteria. These are classified under Chapter 54 as man-made filaments and are distinct from elastomeric monofilaments, which fall under sibling category 5404.11. The key characteristic here is the material: polypropylene. The goods are essentially plastic strands or flattened ribbons with defined physical properties, intended for various industrial or commercial applications.

The distinction from sibling category 5404.11.00.00 lies in the material's inherent elasticity. While both are monofilaments or strips meeting specific cross-sectional dimensions, 5404.11.00.00 is reserved for those exhibiting elastomeric properties, meaning they can stretch significantly and return to their original shape. Category 5404.12, conversely, encompasses polypropylene-based filaments and strips that do not possess these pronounced elastic qualities.

Within this category, further subdivision is provided based on length. Subcategory 5404.12.10.00 pertains to those monofilaments or strips measuring not over 254 millimeters in length. The remaining items, which are longer than 254 millimeters or where length is not a primary distinguishing factor, are classified under 5404.12.90.00. These subcategories allow for more granular classification based on the practical dimensions of the polypropylene filaments or strips.
