About heading 7325
Other cast articles of iron or steel
Heading 7325 covers articles of iron or steel that are cast, not forged or fabricated from sheet or bar. It is split first by whether the cast iron is nonmalleable (7325.10, mainly ground and utility hardware such as covers, frames and boxes) or falls in the residual Other group. The Other group separates grinding balls and similar mill articles (7325.91) from all remaining cast articles, which are divided between cast iron (7325.99.10) and other cast material such as cast steel (7325.99.50).
