SITC 73391 covers draw-benches used for bars, tubes, and profiles as well as wire, while SITC 73395 specifically addresses machines for working wire. In practice, a multi-die continuous wire-drawing machine is more likely classified under 73395, whereas a single-die bench pulling bar or tube stock fits 73391. The form of the input workpiece and the machine's mechanical configuration are the deciding factors.

Precision tubing manufacturers serving aerospace, automotive, and hydraulic-system markets are the dominant buyers. Specialty fastener and medical-device wire producers also rely on draw-benches to achieve the tight dimensional tolerances and surface finishes that rolling cannot deliver.
