7307.23.00.90 - Other 🖩

This category, HTS 7307.23.00.90, covers "Other" butt welding fittings made of stainless steel. These are fittings designed to join pipes or tubes through the process of welding directly onto the ends of the pipes or tubes. The scope here is for those fittings that do not fit into the more specifically defined categories at this level, particularly those that have undergone machining, tooling, or other processing after their initial forming.

It's important to distinguish this subcategory from its sibling, 7307.23.00.30, which specifically covers butt welding fittings of stainless steel that have *not* been machined, tooled, or otherwise processed after forming. Therefore, HTS 7307.23.00.90 is intended for fittings that, while still being butt welding types of stainless steel, have undergone some level of subsequent modification or finishing beyond basic forming. Examples might include fittings with special surface treatments, additional threading applied after the initial butt weld shape is created, or other alterations that differentiate them from raw, un-processed formed fittings.

As this is a leaf node within the HTS classification system, there are no further subcategories. Classification within this specific code hinges on the material (stainless steel), the joining method (butt welding), and the fact that it has undergone processing beyond its initial formation, distinguishing it from less processed alternatives.
