7307.11.00.60 - Other

This category, 7307.11.00.60, encompasses "other" fittings of iron or steel that are cast and made from nonmalleable cast iron. These fittings are designed for use with tubes and pipes, serving functions such as joining, changing direction, or terminating pipe runs. The "other" designation indicates that these are fittings not specifically covered by other subcategories within the nonmalleable cast iron fittings for tubes and pipes.

The key differentiator for this subcategory is its exclusion of fittings specifically intended for cast-iron soil pipe applications. While both fall under nonmalleable cast iron fittings, 7307.11.00.45 is exclusively for soil pipe usage. Therefore, any nonmalleable cast iron pipe fitting that is not explicitly designed or marketed for soil pipe systems would fall under this residual "other" classification.

As a leaf node, this category does not have further subcategories. Classification decisions within this HTS code rely on confirming that the fitting is indeed made of nonmalleable cast iron, is a fitting for tubes or pipes of iron or steel, and does not fall under the more specific category for cast-iron soil pipe fittings. Examples could include certain types of industrial pipe elbows, couplings, or reducers constructed from nonmalleable cast iron intended for general fluid conveyance or other industrial piping systems.
