U.S. imports of Non-CNC Boring-Milling Machines for Metal (Not Elsewhere Specified) (SITC 73145) totaled $316K in August 2026, imported from 8 countries.
Importers of Non-CNC Boring-Milling Machines for Metal (Not Elsewhere Specified) paid $46K in duties in August 2026, an average duty rate of 14.67% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Non-CNC Boring-Milling Machines for Metal (Not Elsewhere Specified) imports of $316K in August 2026 ran 23% below the year-to-date monthly average of $410K.
Last updated: August 2026 dataConventional boring-milling machines — those without numerical control — occupy SITC 73145 and are primarily used in repair shops, prototype facilities, and markets where skilled manual operators are available and CNC programming overhead is not justified. The absence of numerical control is the defining classification criterion separating this heading from 73144, and importers must confirm control type from the machine's technical documentation. These machines retain a global market in maintenance-intensive industries such as mining, rail, and power generation, where large, one-off bore repairs are common.

Yes. A digital readout that displays axis position without driving the axes under program control does not constitute numerical control. Such a machine classifies in the non-CNC boring-milling heading 73145, not in the CNC heading 73144. The presence of servo-driven, programmable axis motion is the threshold for CNC classification.
Trade-remedy coverage for metalworking machine tools varies by origin country and specific product type. Antidumping and countervailing duty orders have historically targeted certain machine-tool categories from specific countries. Importers should check the current CBP and International Trade Administration databases for active orders applicable to the specific origin before entry.
