U.S. imports of parts & accessories for forging, stamping, shearing & metal-forming machine tools (headings 8462–8463) (HS 846694) totaled $46.9M in April 2026, traded with 58 countries.
Importers of Parts & Accessories for Forging, Stamping, Shearing & Metal-Forming Machine Tools (Headings 8462–8463) paid $5.6M in duties in April 2026 — an effective duty rate of 14% on $40.3M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataPress brakes, mechanical transfer presses, stamping machines, and wire-drawing equipment (headings 8462–8463) rely on the parts classified here, which the US schedule divides by material (cast-iron beds, bases, and weldments vs. non-cast-iron components) and by machine type, with dedicated lines for mechanical transfer press parts (8466946540, 8466948540). Germany and Japan are the leading US suppliers, reflecting their dominance in heavy stamping and forming equipment used by the automotive and aerospace supply chains. Section 301 tariffs affect Chinese-origin parts across this subheading, a significant cost factor given China's role in producing lower-cost press tooling and structural castings. Importers should distinguish between parts of forging/stamping machines (8462) and parts of wire-drawing or tube-bending machines (8463) when selecting the correct line.

Mechanical transfer presses are high-value, high-throughput systems central to automotive body-panel and structural-component production. Their parts (8466946540 and 8466948540) are separated from general heading 8462/8463 parts to allow more precise trade monitoring and, in some cases, distinct duty treatment. Importers should confirm that the press in question is a true mechanical transfer press — one that moves workpieces between stations automatically — rather than a conventional mechanical press.
The importer should retain the manufacturer's technical specification confirming the part is cast iron and identifying the host machine (heading 8462 or 8463). The cast-iron material classification lines (8466942000 and 8466944000) require that the part be cast iron — not fabricated steel weldments, which are treated separately. A material certification or mill test report from the German supplier is the standard supporting document.
