U.S. imports of machining centers for working metal (HS 845710) totaled $110.8M in April 2026, traded with 20 countries.
Last updated: April 2026 dataMachining centers are the backbone of modern precision metalworking, integrating milling, drilling, and boring operations with automatic tool changers (ATC) in a single setup — a capability that drives their dominance in aerospace, automotive, and die-mold production. Japan and Germany are the leading US import sources under this heading, with South Korea and Taiwan also significant, reflecting the concentration of advanced CNC machine-tool manufacturing in East Asia and Europe. The US tariff schedule is unusually granular here, distinguishing vertical-spindle centers by Y-axis travel (under or over 660 mm), horizontal-spindle centers by pallet size, and used/rebuilt units — each distinction carrying its own 10-digit line. Importers of used or rebuilt machining centers (8457100005) should be prepared to document condition and prior service history to support correct classification.

CBP typically looks at the commercial invoice, manufacturer's certificate of origin, and any refurbishment records. A machine that has been reconditioned but retains its original structural components is generally classified as rebuilt. Importers should obtain a detailed condition report from the seller and be prepared to present it at entry; misclassification between used and new lines can affect duty liability and statistical reporting.
The US schedule splits vertical-spindle machining centers with ATC at a 660 mm Y-axis threshold (8457100015 for travel not over 660 mm; 8457100025 for over 660 mm). This distinction reflects the machine's capacity class and is used for statistical and, in some cases, duty-rate purposes. Importers should confirm the machine's actual Y-axis travel from the manufacturer's technical specification sheet before filing entry.
