Explore global trade with HS codes

HS Code 8474 encompasses machinery for sorting, screening, separating, washing, crushing, grinding, mixing, or kneading earth, stone, ores, or other mineral substances. The classification includes detailed subcategories for sorting/screening/separating/washing machines (8474.10), crushing/grinding machines (8474.20), mixing/kneading machines (8474.31-8474.39), other machinery (8474.80), and parts (8474.90). This mineral processing equipment category includes machinery for transforming raw geological materials into processed forms. Products range from simple aggregate screens to complex crushing and separation systems for mining operations. Technical specifications focus on throughput capacity, particle size reduction ratios, separation efficiency, and durability under extremely abrasive operating conditions. Applications span construction materials production, mining, recycling, and ceramics manufacturing. This division represents heavy industrial equipment that enables the conversion of raw mineral resources into usable materials for construction, manufacturing, and infrastructure development, forming a critical link between raw resource extraction and the production of refined mineral products suitable for industrial applications.
