Last updated: April 2026 dataMetallurgical converters — vessels used to refine molten metal by injecting air or oxygen, most notably in steelmaking — enter the US under a single tariff line (8454100000) and represent high-value capital equipment for the primary metals industry. Italy leads US imports of this equipment, with Malaysia and Germany also notable sources. Because these are large, purpose-built industrial assets, procurement cycles are long and shipments are infrequent, making accurate classification and valuation at entry especially important for customs compliance.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
A converter (8454.10) is used to refine or process molten metal — typically by blowing air or oxygen through it to remove impurities — before the metal is shaped. A casting machine (8454.30) is used to shape molten metal into a specific form. The functional stage in the metalworking process (refining vs. shaping) is the key distinction CBP applies.
Section 232 tariffs apply to steel and aluminum products, not to machinery used to produce them. Converters classified under 8454.10 are machinery and are not themselves steel or aluminum articles subject to Section 232. However, importers should confirm the classification with a licensed customs broker, as the steel content of the converter itself does not change its classification as machinery.
