Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pre-charged in fire extinguishers or suppression system canisters
Products put up as charges for fire extinguishers are specifically excluded from Chapter 29 by note 2(k) and classified in heading 3813.
If when blended with inert gases like nitrogen for suppression systems
Blends containing additives for specific fire suppression render it a mixture under Chapter 38, not pure compound.
