About heading 8515

Electric (including electrically heated gas), laser or other light or photon beam, ultrasonic, electron beam, magnetic pulse or plasma arc soldering, brazing or welding machines and apparatus, whether or not capable of cutting; electric machines and apparatus for hot spraying of metals or cermets; parts thereof

Heading 8515 covers machines and apparatus that join metal or plastics by soldering, brazing or welding, including electric resistance, arc, laser, ultrasonic, electron beam and plasma arc processes, plus machines for hot spraying metals. It is split first by process (soldering/brazing, resistance welding of metal, arc welding of metal, other), then by whether the machine is fully or partly automatic, with a final group for parts. Duty rates in this heading range from Free to 2.5%.
