U.S. imports of plasma and vacuum arc furnaces (HS 851432) totaled $117K in July 2026, traded with 8 countries.
Importers of Plasma and Vacuum Arc Furnaces paid $20K in duties in July 2026 — an effective duty rate of 17% on $117K in dutiable value, based on actual customs collections rather than the published tariff schedule. Plasma and Vacuum Arc Furnaces imports of $117K in July 2026 ran 87% below the year-to-date monthly average of $874K.
Last updated: July 2026 dataPlasma arc and vacuum arc remelting (VAR) furnaces are critical refining tools for producing homogeneous, inclusion-free ingots of superalloys, titanium, and specialty steels demanded by aerospace, defense, and medical-device supply chains. Germany leads US imports under this heading, consistent with its strength in high-specification metallurgical capital equipment, with Austria and Poland also among the top suppliers. The two US tariff lines under this heading separate a base provision (8514320000) from a residual 'not elsewhere specified' line (8514329000), and correct classification often hinges on whether the unit operates by plasma torch or by consumable-electrode vacuum arc discharge.

Both fall within heading 851432, but the operating principle differs: plasma arc furnaces use an externally generated plasma torch as the heat source, while vacuum arc remelting (VAR) furnaces use a consumable electrode that arcs under vacuum. Customs classification is based on the equipment's described operating mechanism in the manufacturer's technical documentation, not on the end-product metal.
Imports from certain origins may be subject to Section 301 tariffs or other trade-remedy measures depending on the country of origin and the specific tariff line. Importers should verify current remedy orders with CBP or a licensed customs broker before entry, as applicability can change with administrative reviews.
