About HS Code 845521
This specific HS code focuses on metal-rolling mills designed for hot rolling or a combination of hot and cold rolling processes. Hot rolling involves processing metal at high temperatures, above its recrystallization point, to achieve significant deformation and reduce thickness, while combination mills offer the flexibility for both hot and subsequent cold processes. These mills are central to the primary shaping of steel and other metals into semi-finished products like slabs, blooms, and billets, as well as finished products like plates and strips. Importers are typically large integrated steelworks and major metal processing companies worldwide, investing heavily to meet global demand for basic metal products. Exporters are specialized heavy machinery manufacturers with advanced engineering capabilities. The trade in these massive, high-investment machines is a key indicator of global industrial capacity and demand for foundational metal products.
Products Under This Code
