5404.12.10.00 - Not over 254 mm in length

This HTS category, 5404.12.10.00, specifically classifies synthetic monofilaments that are made of polypropylene and have a length not exceeding 254 millimeters. These monofilaments must also meet the criteria of being of 67 decitex or more and have no cross-sectional dimension exceeding 1 millimeter. This precise definition ensures that only a specific subset of synthetic monofilaments, characterized by their material, decitex, cross-sectional dimensions, and importantly, their limited length, are included here.

This subcategory distinguishes itself from its sibling, 5404.12.90.00 ("Other"), by the specific length criterion. While both fall under synthetic monofilaments of polypropylene, the "Other" category would encompass monofilaments of polypropylene that do not meet the 254 mm length limitation defined here. The "Other" category serves as a residual classification for polypropylene monofilaments at this level that don't fit the more narrowly defined parameters of this specific heading.

As this is a leaf node in the HTS structure, there are no further subcategories. Therefore, the focus for classification under 5404.12.10.00 is on the definitive physical attributes and material specified. When classifying goods, it is crucial to verify that the polypropylene monofilament not only meets the decitex and cross-sectional dimension requirements but also its length is 254 millimeters or less.
