HS Code 8455.22 – Metal-rolling mills; cold
HS code 8455.22 is the 6-digit subheading for metal-rolling mills, cold. It is used for cold tandem mills, reversing cold mills, temper mills, skin pass mills and sendzimir mills.
What HS 8455.22 covers
This HS code covers cold metal-rolling mills, which are sophisticated industrial machines designed to reduce the thickness, improve the surface finish, and enhance the mechanical properties of metal strips and sheets at room temperature. Unlike hot rolling, cold rolling significantly increases the material's strength and hardness, making it crucial for high-quality applications. Key players in international trade include major steel, aluminum, and non-ferrous metal producers who import these capital goods to upgrade or expand their production capabilities. Exporters are typically specialized heavy machinery manufacturers from technologically advanced nations. The market is driven by demand from the automotive, construction, packaging, and appliance industries, all requiring precise and high-strength metal products. Understanding the specific capabilities and automation levels of these mills is vital for accurate trade classification and valuation.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
