Classification under 7325.99 is appropriate only after ruling out more specific provisions. Importers should first check whether the article is a grinding ball (7325.91), a sanitary ware item (7324), a pipe fitting (7307), or another specifically described article elsewhere in Chapter 73 or in other chapters. The NESOI designation means 7325.99 is a residual provision; a thorough classification analysis using the General Rules of Interpretation is required before defaulting to it.
Yes. The US tariff schedule separates other cast iron articles (7325991000) from other cast steel articles (7325995000), and these lines may carry different duty rates.

Importers should confirm the material specification — particularly carbon content and whether the article is iron or steel — with the manufacturer before filing entry.
