Importers of Milling Tools (Base Metal) paid $4.1M in duties in August 2026, an average duty rate of 12.54% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Milling Tools (Base Metal) imports of $32.4M in August 2026 ran 13% above the year-to-date monthly average of $28.7M.
Last updated: August 2026 dataEnd mills, router bits, and other milling cutters are core consumables in CNC machining, woodworking, and composite fabrication, with demand driven by aerospace, automotive, and furniture manufacturing. The US schedule under 820770 separates end milling cutters (8207701000, 8207703030, 8207706030), router bits for woodworking (8207703040, 8207704000, 8207706040), and other milling tools (8207703060, 8207706060), with alloy-content thresholds again creating parallel lines for high-alloy versus standard cutting parts. Germany and Italy lead US imports, with South Korea and Israel also notable sources — reflecting strong European and Israeli precision tooling industries.

Solid carbide end mills classify under 820770 (milling tools), not 820713 (cermet rock drilling tools). Heading 820713 is limited to rock drilling and earth boring tools whose working part is of cermet. End mills, even those made entirely of cemented carbide, are milling tools and belong in 820770. The alloy-content lines within 820770 (e.g., 8207703030) apply when the cutting part meets specified chromium, molybdenum, tungsten, or vanadium thresholds.
Yes. The US schedule distinguishes router bits for woodworking with specified alloy-content cutting parts (8207703040) from general router bits (8207704000) and router bits not suitable for cutting metal (8207706040). Metal-cutting router bits fall under different lines. Importers should confirm the intended substrate — wood, composite, or metal — and the cutting-part alloy content to select the correct 10-digit line.
