Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pre-packaged as pharmaceutical preparation for medical use
Gases prepared for therapeutic applications may shift to Chapter 30 as pharmaceutical products.
If when supplied filled in surgical instruments
Integral gases in medical/surgical instruments are classified under 9018 with the device.
If the gas is helium instead
Helium for medical uses like MRI is under separate rare gas code 2804.20.
