Heading 7325

Other cast articles of iron or steel

9 declarable lines

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).

How to choose the right subheading

Confirm the article is cast rather than welded, stamped or machined from bar, since heading 7325 covers cast articles only.
For nonmalleable cast iron ground and utility hardware, pick the specific 7325.10 line by product type: covers, basin grates, cleanout covers, valve boxes, meter boxes.
Check whether the item is a grinding ball or similar article for mills, which goes to 7325.91 regardless of the iron or steel type.
For remaining cast articles, decide the metal: cast iron goes to 7325.99.10, other cast material such as cast steel goes to 7325.99.50.
If the product is a part of a specific machine or appliance covered by another heading, classify it with that machine rather than in 7325.
