HS Code 8455.30 – Metal-rolling mills; rolls thereof
HS code 8455.30 is the 6-digit subheading for metal-rolling mills, rolls thereof. It is used for work rolls, backup rolls, intermediate rolls, cast iron rolls and forged steel rolls.
What HS 8455.30 covers
This code specifically covers the rolls used in metal-rolling mills, which are critical, high-precision components essential for shaping metals. These rolls are manufactured from specialized alloys, designed to withstand immense pressure, high temperatures (in hot rolling), and abrasive forces while maintaining precise dimensions and surface finishes. The trade in these components is continuous, involving both new rolls for mill construction and replacement rolls for maintenance and operational efficiency. Importers are typically metal producers (steel, aluminum, copper) and mill operators globally, while exporters are specialized manufacturers of these durable components. Key considerations for trade include material composition, hardness, surface finish, and dimensional accuracy, as they directly impact the quality of the rolled metal products and the mill's productivity. The global demand is tied to the health of the metal production industries, with significant trade flows between industrial nations.

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).
