Summary
HS code 8456.40 covers operated by plasma arc processes. It sits in heading 84.56 (machine-tools for working any material by removal of material, by laser or other light or photon beam, ultrasonic, electro- discharge, electro-chemical, electron beam, ionic-beam or plasma arc processes; water-jet cutting machines) in chapter 84 (nuclear reactors, boilers, machinery and mechanical appliances; parts thereof). Other goods of heading 84.56 are classified under 8456.11 (operated by laser or other light or photon beam processes, operated by laser), 8456.12 (operated by laser or other light or photon beam processes, operated by other light or photon beam processes), 8456.20 (operated by ultrasonic processes), 8456.30 (operated by electro-discharge processes) or 2 others. National tariff lines under 8456.40 are live on border.bot for the United States (3 lines, also used by 1 other country).
