7307.29.00.90 - Other

This HTS classification, 7307.29.00.90, encompasses "Other" fittings of stainless steel used for tubes or pipes. These articles, made from iron or steel, serve the crucial function of connecting, terminating, or adapting pipes and tubes within fluid or gas conveyance systems. This broad category includes a wide array of stainless steel fittings not specifically enumerated elsewhere within the 7307.29.00 subheadings.

Distinguishing this category from its sibling, 7307.29.00.30, which specifically covers "Nipples," is key. While nipples are a specific type of threaded fitting used to join two pipes or connect a pipe to a valve or other fitting, this "Other" category includes all other stainless steel tube and pipe fittings. Examples falling under 7307.29.00.90 would include elbows, tees, couplings, reducers, caps, and unions made of stainless steel, provided they do not fit the specific definition of a nipple or any other more specifically enumerated classification. The material composition of stainless steel is a defining characteristic for all items within this chapter and heading.

As this is a leaf node within the HTS classification system, there are no further subcategories to introduce. Classification under 7307.29.00.90 is determined by the exclusion of the article from more specific subheadings at this level, such as nipples, and its material composition being stainless steel. The primary classification criteria revolve around the function of the fitting (connecting, terminating, adapting pipes) and its material.
