U.S. imports of parts and accessories for metal-removing machine tools, n.e.s. (SITC 73591) totaled $81.3M in April 2026, traded with 62 countries.
Importers of Parts and Accessories for Metal-Removing Machine Tools, N.E.S. paid $10.0M in duties in April 2026 — an effective duty rate of 14% on $73.5M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataCovering replacement and accessory parts for lathes, milling machines, grinding machines, and other metal-cutting machine tools, this residual heading is one of the most widely used in the machine-tool trade because virtually every metalworking facility is a potential buyer of spare parts. The 'solely or principally' use test is the central classification challenge: a part must be demonstrably dedicated to metal-removing machine tools rather than being a general-purpose mechanical component. Section 301 tariffs have made country-of-origin analysis particularly important for this heading, as a significant share of machine-tool parts are sourced from China.

CBP expects evidence such as the OEM part number and the specific machine model it fits, manufacturer technical literature, and commercial invoices that identify the end-use machine. If the part is a standard mechanical component (bearings, seals, fasteners) that could fit many machine types, additional documentation showing the predominant use in metal-cutting equipment strengthens the classification claim.
Parts sourced from China are subject to Section 301 tariffs, which have materially increased landed costs for many buyers. As a result, importers have explored alternative sourcing from Taiwan, Japan, Germany, and South Korea. However, origin-shifting strategies must be supported by genuine manufacturing in the alternative country — CBP scrutinizes transshipment and substantial-transformation claims closely for machine-tool components.
