U.S. imports of numerically controlled horizontal lathes for removing metal (HS 845811) totaled $70.0M in April 2026, traded with 22 countries.
Last updated: April 2026 dataNumerically controlled (N/C) horizontal lathes are a foundational machine tool for turned-part production across aerospace, automotive, and energy sectors, with CNC control enabling repeatable, high-precision cuts on cylindrical workpieces. Japan is the leading US import source under this heading, followed by South Korea and Taiwan, reflecting East Asia's dominant position in CNC lathe manufacturing. The US tariff schedule segments these lathes by spindle configuration and motor power — with thresholds at 18.65 kW and 37.3 kW for single-spindle units (8458110030, 8458110050, 8458110090) — making accurate motor-power documentation from the manufacturer essential for correct entry. Multi-spindle N/C horizontal lathes (8458110010) and used or rebuilt units (8458110005) are separately classified.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Motor power (in kilowatts) is the primary breakpoint for single-spindle N/C horizontal lathes: under 18.65 kW (8458110030), between 18.65 kW and 37.3 kW (8458110050), and over 37.3 kW (8458110090). Importers should obtain the rated motor power from the manufacturer's technical datasheet and ensure it matches the value declared on the commercial invoice to avoid reclassification.
Yes — used and rebuilt N/C horizontal lathes are classified under a dedicated line (8458110005) separate from new machines. While the duty rate structure may differ, the more significant practical issue is that CBP may scrutinize the condition declaration. Importers should document the machine's service history, any refurbishment performed, and the basis for the declared customs value, as undervaluation of used machinery is a common audit focus.
