Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If blended with hydrogen for specific plasma cutting
Hydrogen-argon mixtures for welding or cutting are artificial gases under 3811.21.
If as produced machinery parts manufactured using argon
Products made with argon in the process are classified by their final form, not the gas used.
If the rare gas is krypton
Krypton has its dedicated subheading 2804.50 within rare gases.
