HS Code for Mill balls
Mill balls are classified under HS code 7325.91, which specifically addresses grinding balls and similar articles for mills. This classification is determined by the material composition—iron or steel—and the manufacturing process, which is casting. According to the General Rules of Interpretation (GRI), products are classified based on their heading and any relative section or chapter notes. Since these items are cast articles of iron or steel intended for use in grinding mills, they fall under heading 7325. The subheading 7325.91 is reserved for grinding balls and similar articles, excluding those made of non-malleable cast iron, which would be classified elsewhere. The durability and specific spherical shape designed for industrial grinding processes define their placement here. The classification remains consistent regardless of whether the balls are used in the mining, cement, or chemical industries, provided they meet the metallurgical definition of cast steel or malleable iron. If the balls were forged rather than cast, the classification would shift to a different heading entirely, making the production method the primary determinant for this specific code.

Common Misclassification
A frequent error involves confusing 7325.91 with HS code 7326.11. While both codes cover grinding balls, 7326.11 is strictly for forged or stamped articles that have not been further worked. Another common mistake is attempting to classify these as machinery parts under 8474.90. However, because mill balls are considered consumable grinding media and are specifically named in Chapter 73, the specific article code takes precedence over the general machinery part code.
