U.S. imports of parts & accessories for metalworking & laser machine tools (headings 8456–8461) (HS 846693) totaled $94.8M in July 2026, traded with 71 countries.
Importers of Parts & Accessories for Metalworking & Laser Machine Tools (Headings 8456–8461) paid $10.5M in duties in July 2026 — an effective duty rate of 13% on $82.9M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataCovering parts for laser, EDM, machining center, lathe, drilling, milling, grinding, and gear-cutting machines (headings 8456–8461), this subheading is one of the most granular in the machine-tool chapter, with 14 active US tariff lines that separate water-jet cutting parts (8466931100), cast-iron structural components, gear-cutting machine parts, beds and bases, and parts for printed-circuit-board manufacturing machines (8466939600). Germany and Japan lead US imports, consistent with their roles as premier suppliers of precision machining centers and grinding equipment. Section 301 tariffs apply to Chinese-origin goods across most lines, making supplier diversification toward Germany, Japan, Italy, and Canada a strategic priority for US machine-tool rebuilders and OEM service operations.

Line 8466939600 specifically covers parts of machines of headings 8456–8461 used in the manufacture of printed circuit boards and similar electronic substrates. This carve-out reflects the specialized nature of PCB drilling, routing, and laser-processing equipment. Importers of parts for these machines should confirm that the host machine's principal function is PCB fabrication to support classification on this line rather than a general NESOI line.
Water-jet cutting machine parts have their own dedicated 10-digit line (8466931100), separating them from the cast-iron and non-cast-iron lines that cover conventional metalworking machines. This means the material-composition split (cast iron vs. other) that governs most other lines does not apply to water-jet parts — the cutting technology itself is the primary classification criterion.
