7307.93.30 - Of iron or nonalloy steel

This HTS category, 7307.93.30, specifically covers fittings for tubes and pipes made from iron or non-alloy steel, which are designed for butt welding and have an inside diameter of less than 360 mm. These fittings are essential components used to join pipes or alter the direction of fluid or gas flow within a system. Examples include elbows, tees, reducers, and couplings, all manufactured to be welded directly onto the ends of pipes.

Distinguishing this category from its sibling, 7307.93.60.00, lies in the material composition. While this heading exclusively pertains to fittings of iron or non-alloy steel, the sibling category encompasses fittings made from alloy steel, excluding stainless steel. Therefore, the precise metallurgical content is a critical determinant for proper classification.

Within this classification, further subdivisions exist to refine the classification based on post-forging processing. Subcategory 7307.93.30.10 is designated for fittings that remain in their as-forged state, meaning they have not undergone any machining, tooling, or other subsequent processing after the initial forging operation. The subcategory 7307.93.30.40 encompasses all other fittings within this scope that have been subjected to additional manufacturing steps beyond forging.
