U.S. imports of Numerically Controlled Horizontal Lathes for Metal Removal (SITC 73131) totaled $75.6M in August 2026, imported from 24 countries.
Importers of Numerically Controlled Horizontal Lathes for Metal Removal paid $8.6M in duties in August 2026, an average duty rate of 11.77% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Numerically Controlled Horizontal Lathes for Metal Removal imports of $75.6M in August 2026 ran 14% above the year-to-date monthly average of $66.5M.
Last updated: August 2026 dataNumerically controlled (NC) horizontal lathes are the dominant configuration for high-precision turning of shafts, flanges, and cylindrical components in automotive, oil-and-gas, and general engineering applications, with CNC control enabling repeatable tolerances across production runs. The horizontal spindle orientation and NC designation are both classification-critical attributes that separate this heading from non-horizontal and manually controlled lathe categories. Section 301 tariff applicability varies by origin country, and importers sourcing from major Asian manufacturing centers should verify current trade-remedy status before committing to procurement contracts.

A numerically controlled lathe uses programmed numerical data to direct machine movements automatically. A digital readout (DRO) that only displays position without directing axis movement does not constitute numerical control. CBP looks for evidence of programmed axis control — typically CNC or NC controllers — when evaluating this classification criterion.
Horizontal and non-horizontal (including vertical) CNC lathes fall under separate SITC headings. The spindle axis orientation is a primary classification criterion, so importers must confirm whether the machine's spindle is horizontal before applying this heading. Slant-bed lathes with a horizontal spindle axis generally qualify as horizontal lathes.
