Product classification
HS code for Metallurgical converter: 8454.10
Converters, of a type used in metallurgy or in metal foundries.
Classification of metallurgical converter under HS 8454.10
The metallurgical converter is classified under HS code 8454.10. Heading 8454 is part of Chapter 84 and specifically addresses equipment used in metallurgy and metal foundries. Converters are specialized vessels used to refine molten metals. The process involves blowing air or oxygen through the molten mass to oxidize impurities like carbon, silicon, and manganese. This chemical transformation is what distinguishes a converter from a standard melting furnace. Under the General Rules of Interpretation (GRI), products are classified according to the terms of the headings and any relative Section or Chapter notes. Since 8454 specifically mentions converters, and 8454.10 is the specific subheading for them, this classification is straightforward for heavy industrial equipment used in steelmaking or copper smelting. These machines are typically massive, refractory-lined steel shells capable of tilting to pour out the refined metal and slag. They are essential components in the production of steel from pig iron and the refining of non-ferrous metals. The classification excludes the heating elements if they are separate, but includes the vessel and its integrated tilting mechanism.

Codes often confused with 8454.10
Common mistake. Metallurgical converters are sometimes confused with industrial furnaces and ovens classified under HS code 8417. While both involve high heat, a converter is specifically designed for the chemical transformation of the metal charge via gas injection, whereas a furnace is primarily for melting or heating. They are also distinct from casting machines found in 8454.30.
Top exporters and importers of HS 845410 (the code used for metallurgical converter), 2025
In 2025, the largest exporter of HS 845410 (the code used for metallurgical converter) in UN Comtrade data was Germany, with 37% of world exports; the largest importer in UN Comtrade data was Indonesia, 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).
