7307.93.30.10 - Not machined, not tooled and not otherwise processed after forging 🖩

This HTS category, 7307.93.30.10, specifically classifies butt welding fittings of iron or nonalloy steel that have an inside diameter of less than 360 mm, and importantly, have not undergone further processing such as machining or tooling after the initial forging. This means the fittings are presented in their forged state, without any modifications that alter their fundamental shape or intended function beyond the forging process itself. Examples would include forged elbows, tees, or reducers intended for butt welding into pipe systems, where the surfaces remain as a direct result of the forging operation.

Distinguishing this category from its sibling, 7307.93.30.40 ("Other"), is the explicit exclusion of any post-forging processing. While both fall under butt welding fittings with an inside diameter under 360 mm and are of iron or nonalloy steel, the sibling category would encompass fittings that have been machined, tooled, or otherwise altered after forging, perhaps to achieve tighter tolerances or to prepare for specific connection types. This distinction is crucial for accurate classification, focusing on the manufacturing stage and the level of finishing applied to the article.

As this is a leaf node in the HTS, there are no further subcategories. Therefore, the classification hinges on meeting all the preceding criteria: being a butt welding fitting, made of iron or nonalloy steel, possessing an inside diameter less than 360 mm, and most critically, having undergone no machining, tooling, or other processing after its initial forging. This precise definition ensures that only fittings in their as-forged state, without subsequent finishing operations, are correctly identified under this tariff code.
