7307.19.30.60 - Threaded

This HTS category, 7307.19.30.60, specifically covers threaded tube or pipe fittings made of iron or steel that are cast. These fittings are designed for connecting pipes or tubes and are characterized by having threads that allow for a secure, screwed connection. Examples within this classification would include threaded elbows, couplings, and tees where the internal or external threads are the primary means of assembly.

It is important to distinguish this category from its sibling, 7307.19.30.70, which covers cast fittings with mechanical, push-on (rubber compression), or flanged joints attached. While both are cast iron or steel fittings, the defining characteristic for 7307.19.30.60 is the threaded connection, whereas 7307.19.30.70 encompasses fittings that utilize other distinct jointing mechanisms for connection.

As this is a leaf node in the HTS classification, there are no further subcategories. Classification under 7307.19.30.60 is final for threaded cast fittings of iron or steel that do not fall under other more specific classifications for joint types. The presence of threads is the key determinant for inclusion in this specific sub-heading.
