Parts of Machinery for Sorting, Screening, Separating, Crushing, or Processing Mineral Substances

Replacement and service parts for heavy mineral-processing equipment — including screens, separators, crushers, grinders, and mixers used in mining, quarrying, and aggregate production — are classified here and subject to Section 301 tariffs when sourced from China. The US schedule breaks the heading into four functional lines: parts for sorting/screening/washing/separating (8474900010), parts for crushing or grinding (8474900020), parts for mixing or kneading (8474900050), and residual parts including foundry mold machinery (8474900090). Germany leads supply, reflecting that country's deep specialization in bulk-material handling equipment, with Canada and China also significant sources. Importers should verify whether specific parts are classifiable here or under a more specific machinery heading, as misclassification between Chapter 84 parts provisions is a common audit finding.
