HS code for Cold rolling mill: 8455.22
Metal-rolling mills, cold.
Classification of cold rolling mill under HS 8455.22
HS code 8455.22 is assigned to cold-rolling mills used for processing metal. This classification falls under Chapter 84, which encompasses nuclear reactors, boilers, machinery, and mechanical appliances. Heading 8455 specifically covers metal-rolling mills and the rolls designed for them. The primary distinction within this heading is between hot-rolling mills (8455.21) and cold-rolling mills (8455.22). A cold-rolling mill is a machine that reduces the thickness of metal sheets or strips by passing them through rollers at temperatures below their recrystallization temperature, typically at room temperature. This process is essential for producing materials with high dimensional accuracy and superior surface quality. The classification is based on the functional purpose of the machinery. It is important to note that this code refers to the mill itself—the machine assembly—rather than the individual components like the rollers, which have their own specific classification under 8455.30. The machinery must be specifically designed for the cold-rolling process to be classified here. If a mill is capable of both hot and cold rolling, it is generally classified based on its primary use or under the subheading for hot-rolling mills if both functions are equally significant, following the rules of the HS nomenclature. Furthermore, this code does not include machine tools for working metal by bending, folding, or shearing, which are classified under heading 8462. Proper classification requires a detailed technical description of the mill's operating temperature and its intended metal-working application.

Codes often confused with 8455.22
Common mistake. The most common misclassification is using 8455.21, which is reserved for hot-rolling mills or combined hot-and-cold mills. Another frequent error is classifying individual mill rolls under 8455.22, whereas they should be under 8455.30. Additionally, some importers confuse these with metal-working machine tools under 8462, which perform different mechanical operations like forging or bending.
Top exporters and importers of HS 845522 (the code used for cold rolling mill), 2025
In 2025, the largest exporter of HS 845522 (the code used for cold rolling mill) in UN Comtrade data was China, with 41% of world exports; the largest importer in UN Comtrade data was India, with 26% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
