7307.19.90.60 - Threaded

This HTS classification, 7307.19.90.60, specifically designates "Threaded" fittings for tubes or pipes made of iron or steel that fall under the "Other" subcategory of "Cast fittings." These are generally threaded couplings, elbows, sleeves, or similar connecting pieces, manufactured through a casting process, and not otherwise specifically enumerated. The "threaded" aspect refers to the presence of internal or external screw threads designed for connecting pipes or tubes.

This specific subcategory distinguishes itself from its sibling, 7307.19.90.80, which is also classified as "Other" but does not carry the explicit "Threaded" descriptor. Therefore, 7307.19.90.60 is reserved for cast iron or steel pipe fittings that are threaded, while the sibling category likely covers other forms of cast fittings that are not threaded, such as those joined by welding, compression, or other non-threaded methods, or those whose primary function is not threading.

As this is a leaf node in the HTS structure, there are no further subcategories. The classification of an item under 7307.19.90.60 hinges on its identification as a cast iron or steel fitting for tubes or pipes, and crucially, its possession of threaded connections, differentiating it from other potential cast fitting types.
