Forged Alloy Steel Mill Grinding Balls from Japan
Although primarily cast, certain alloy steel balls are forged then heat-treated for superior toughness in overflow ball mills. However, if truly cast, they align with HTS 7325.91.00.00 as grinding articles for mills. Used extensively in cement and power plant pulverizers.

Import Tips
• Request casting process documentation; forged items risk reclassification—ensure foundry certificates specify cast method
• Comply with country-of-origin rules; many originate from China/India—check AD/CVD orders for steel articles
