Last updated: April 2026 data

Shaping and slotting machines remove metal by a single-point tool moving in a linear reciprocating stroke — shaping machines work horizontally across the workpiece, while slotting machines operate vertically to cut keyways, splines, and internal profiles. Both are mature technologies that remain commercially relevant for low-volume, large-workpiece applications in heavy equipment repair, gear manufacturing, and toolroom work where broaching or milling would be less economical. Their relatively specialized application base means trade volumes are modest compared to CNC machining centers, but they remain actively imported for industrial maintenance and rebuild programs.

Frequently Asked Questions

How is a slotting machine distinguished from a broaching machine for trade classification purposes?

A slotting machine uses a single reciprocating tool that removes material in successive passes, with the workpiece or tool indexed between strokes. A broaching machine pulls or pushes a multi-tooth broach through the workpiece in a single stroke. The number of cutting edges engaged simultaneously and the motion pattern are the defining differences; broaching machines fall under a separate SITC heading.

Are shaping and slotting machines subject to any trade-remedy tariffs?

Machines originating from China may be subject to Section 301 tariffs depending on their specific HTS classification at the 10-digit level. Importers should verify current Section 301 product coverage and any granted exclusions against the applicable HTS subheading before finalizing sourcing decisions, as coverage has been updated multiple times since the measures were first imposed.
