HS Code 8454.90 – Machines; parts of converters, ladles, ingot moulds and casting machines, of a kind used in metallurgy or in metal foundries
HS code 8454.90 is the 6-digit subheading for machines, parts of converters, ladles, ingot moulds and casting machines, of a kind used in metallurgy or in metal foundries. It is used for converter refractory linings, ladle refractory bricks, continuous caster rolls, die casting machine dies and hydraulic cylinders for casting machines.
What HS 8454.90 covers
This category encompasses the essential components and spare parts for the heavy-duty machinery classified under 845410 (converters), 845420 (ingot moulds and ladles), and 845430 (casting machines). The trade in these parts is vital for the continuous operation and maintenance of metallurgical and foundry equipment, which are often subjected to extreme temperatures, abrasive conditions, and significant wear. Importers are typically steel mills, foundries, and metal processing plants that require reliable spare parts to minimize downtime, ensure production efficiency, and extend the lifespan of their capital-intensive machinery. Exporters are often the original equipment manufacturers (OEMs) or specialized suppliers of high-performance components. The global flow of these parts is crucial for supporting the world's primary metal industries and maintaining their operational integrity.

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).
