7307.93.30.40 - Other

This HTS classification, 7307.93.30.40, specifically covers butt welding fittings made of iron or non-alloy steel, which have an inside diameter of less than 360 mm, and are neither machined nor tooled after forging, nor otherwise processed. These fittings are essential components used to join sections of piping systems, facilitating changes in direction, diameter, or branching. Their application is prevalent across various industrial sectors requiring robust and reliable fluid or gas conveyance.

The key differentiator for this category lies in its specific processing state. It distinguishes itself from sibling categories such as 7307.93.30.10 by excluding fittings that have undergone any machining, tooling, or other processing after the forging stage. This implies that the fittings under 7307.93.30.40 retain their form as achieved directly from the forging process, without subsequent alterations to their dimensions or surface finish through mechanical means.

As a leaf node in the HTS classification system, this category does not have further subdivisions. Therefore, its scope is precisely defined by the combination of material (iron or non-alloy steel), fitting type (butt welding), diameter constraint (less than 360 mm inside diameter), and the absence of post-forging processing. Importers and exporters should ensure that their goods meet all these specific criteria to ensure correct classification.
