A machine that performs only shearing (straight-line cutting) without an integrated punch tooling station classifies under 73315 when not numerically controlled. Once a machine incorporates a punch station—even if shearing is the primary operation—it moves to the combined punching-and-shearing heading (73316). Reviewing the machine's tooling configuration and OEM specifications is the most reliable way to confirm the correct heading.

Metal-cutting machine tools, including shearing machines, have been subject to antidumping and countervailing duty investigations targeting specific countries of origin at various times. Importers should check the current CBP and USITC databases for any active orders covering the specific machine type and country of manufacture before finalizing sourcing decisions, as duty liability can be substantial.
