HS code for Rolling mill rolls: 8455.30

Metal-rolling mills, rolls thereof.

Classification of rolling mill rolls under HS 8455.30

Rolling mill rolls are classified under HS code 8455.30 because they are the primary working components of metal-rolling mills, which are used to reduce the cross-section of metal or to shape it into specific profiles. According to the General Rules of Interpretation (GIR) 1 and 6, classification is determined by the terms of the headings and subheadings. Heading 8455 covers metal-rolling mills and their parts. Within this heading, subheading 8455.30 specifically identifies \"rolls for rolling mills.\" These components are typically massive, cylindrical tools that come into direct contact with the metal being processed. They must withstand extreme pressure and temperature, leading to their manufacture from specialized materials like chilled cast iron, forged steel, or high-chromium alloys. The classification applies whether the rolls are for hot-rolling or cold-rolling processes, provided they are identifiable as being for use in a metal-rolling mill.

Codes often confused with 8455.30

Common mistake. A frequent error is classifying these rolls under 8455.90, which is the residual category for \"other parts\" of rolling mills. However, because rolls are specifically named in 8455.30, that subheading must be used. Another common mistake involves using 7325.99 or 7326.19, which cover general cast or forged articles of iron or steel. Under Note 2 to Section XVI, parts of machines are generally classified in their respective headings (8455) rather than as general articles of metal in Chapter 73. Additionally, rolls for machines other than metal-rolling mills, such as paper-making machines or calenders, fall under different codes like 8439 or 8420 respectively.

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).
