U.S. imports of ultrasonic machine tools for material removal (HS 845620) totaled $128K in April 2026, traded with 16 countries.
Importers of Ultrasonic Machine Tools for Material Removal paid $20K in duties in April 2026 — an effective duty rate of 16% on $128K in dutiable value, based on actual customs collections rather than the published tariff schedule. Ultrasonic Machine Tools for Material Removal imports of $128K in April 2026 ran 90% below the year-to-date monthly average of $1.3M.
Last updated: April 2026 dataUltrasonic machining uses high-frequency vibration transmitted through a tool and abrasive slurry to erode hard, brittle materials — ceramics, glass, carbides, and composites — that resist conventional cutting. Germany is the leading US supplier under this heading, with Spain and the United Kingdom also notable sources. The US schedule separates metalworking ultrasonic tools by numerical control status (8456201010 for NC, 8456201050 for non-NC) and carves out non-metalworking ultrasonic tools at 8456205000, a line relevant to medical device and semiconductor substrate processing applications. The niche nature of this technology means import volumes are relatively modest but unit values are high.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Line 8456205000 covers ultrasonic tools designed to work materials other than metal — such as ceramics, glass, or composites. Lines 8456201010 and 8456201050 cover metalworking applications, split by NC status. The machine's design intent and the materials it is engineered to process, as documented in the manufacturer's specifications, determine which line applies. A tool marketed for ceramic grinding that can also process metal should be classified based on its principal designed use.
For capital equipment with high unit values, importers should retain the commercial invoice, purchase order, manufacturer's price list, and any assists (such as tooling or software provided free of charge to the manufacturer). CBP may scrutinize related-party transactions or below-market pricing. A first-sale valuation ruling can provide certainty when the supply chain involves an intermediary between the German or Spanish manufacturer and the US buyer.
