7325.99 - Other:

This HTS code, 7325.99, encompasses "Other" articles of iron or steel that are cast but do not fall under specific prior subheadings within 7325.9. It serves as a residual category for a wide array of cast iron or steel articles not otherwise classified. The key unifying characteristic is that these items are manufactured through a casting process and are composed of iron or steel, excluding those with more defined functions or characteristics.

Unlike its sibling, 7325.91.00.00, which specifically covers grinding balls and similar articles for mills, 7325.99.00.00 is for all other cast articles of iron or steel. This means if an article is cast iron or steel and is not intended for milling purposes, its classification would likely fall within this broader residual category.

Within this category, further distinctions are made based on material composition. Subcategory 7325.99.10.00 is designated for articles specifically made of cast iron, while 7325.99.50.00 covers all other cast articles of iron or steel, including those made of other types of iron and steel not classified as cast iron. This subdivision allows for more granular classification based on the specific ferrous alloy used in the casting process.
