Product classification
HS code for Stamped grinding balls: 7326.11
Iron or steel, grinding balls and similar articles for mills, forged or stamped, but not further worked.
Classification of stamped grinding balls under HS 7326.11
HS code 7326.11 is utilized for the classification of grinding balls and similar articles for mills that are made of iron or steel and have been produced through forging or stamping. This code is situated in Chapter 73, which covers articles of iron or steel. The specific sub-heading 7326.11 is reserved for these items provided they have not been "further worked" beyond the forging or stamping process. This means that if the balls have undergone significant machining, precision grinding, or complex surface treatments that change their character beyond a basic forged shape, they might be classified elsewhere. However, for industrial mill applications where the balls are used as grinding media in their forged state, 7326.11 is the correct designation. This classification is essential for the mining, cement, and chemical industries where such media are consumed in large volumes for material size reduction.

Codes often confused with 7326.11
Common mistake. A frequent point of confusion is HS code 7325.91, which covers cast grinding balls. The distinction lies entirely in the manufacturing process: 7326.11 is for forged or stamped balls, while 7325.91 is for those produced in a foundry via casting. Furthermore, some importers mistakenly use 8474.90 (parts of sorting/grinding machinery), but Note 1 to Section XV generally excludes articles of iron or steel from being classified as machine parts if they are specifically provided for in Chapter 73.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
