7307.29.00 - Other

This HTS category, 7307.29.00, encompasses "other" fittings made of stainless steel that do not fall under the more specific subheadings within 7307.2. These are articles of iron or steel, specifically designed for use with tubes or pipes, serving functions like connecting, joining, or altering the flow direction of fluid or gas. The defining characteristic for inclusion here is their material composition of stainless steel, distinguishing them from similar fittings made from other ferrous metals.

This residual category serves to capture stainless steel tube or pipe fittings that are not flanges (7307.21), threaded elbows, bends, or sleeves (7307.22), or designed for butt welding (7307.23.00). Therefore, it includes a diverse range of stainless steel connectors and accessories that are not explicitly defined by these more specific sibling categories.

Within this broad category, two subcategories exist to further refine classification. 7307.29.00.30 specifically covers "nipples," which are short lengths of pipe threaded on the outside at each end, used to connect two other fittings or pipes. The remaining fittings that do not qualify as nipples are classified under the residual 7307.29.00.90, representing all other stainless steel tube or pipe fittings not otherwise specified.
