5607.50.25.00 - 3-ply or 4-ply multicolored twine having a final "S" twist, containing at least 10 percent by weight of cotton, measuring less than 3.5 mm in diameter (201)

This HTS classification, 5607.50.25.00, specifically covers multi-ply twine made from synthetic fibers, characterized by a final "S" twist and a multicolored appearance. The key defining attributes are the construction of three or four plies, the presence of at least 10 percent cotton by weight, and a diameter measuring less than 3.5 mm. These specifications are critical for distinguishing this particular twine from others within the broader category of synthetic fiber twines.

Within the subheadings of "Of other synthetic fibers" and "Not braided or plaited," this category is distinct from its sibling, 5607.50.35.00 ("Other"). While the "Other" category serves as a residual for synthetic fiber twines not meeting the specific criteria of 5607.50.25.00, this classification is reserved for the precisely defined multicolored, multi-ply twine with the specified cotton content and diameter.

As this HTS code is a leaf node, there are no further subcategories. Therefore, classification under 5607.50.25.00 relies solely on meeting all the detailed physical and compositional requirements outlined in its description. Importers and exporters should meticulously verify the ply count, twist direction, cotton content percentage, and diameter to ensure accurate classification of their goods.
