HS Code 8455.10 – Metal-rolling mills; tube mills

HS code 8455.10 is the 6-digit subheading for metal-rolling mills, tube mills. It is used for hot rolling mills, cold rolling mills, plate mills, strip mills and seamless tube mills.

What HS 8455.10 covers

This HS code covers specialized machinery used for shaping metals through rolling, specifically metal-rolling mills and tube mills. Metal-rolling mills reduce the thickness or change the cross-section of metal sheets, strips, or bars, while tube mills form metal into tubes or pipes. These machines are fundamental to the production of a vast array of metal products used in construction, automotive, aerospace, and manufacturing sectors. They are high-capital, complex systems requiring significant investment. Importers are typically large steel manufacturers, non-ferrous metal producers, and specialized tube and pipe factories globally. Exporters are often global leaders in heavy industrial machinery, providing advanced engineering solutions. The trade in these machines reflects the global demand for processed metal products and is a key indicator of industrial capacity and infrastructure development worldwide.

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).
