Aha! So it seems the issue is with pure Isobutane, which although is may be less explosive than the Isobutane+propane mix, the fact is meant for industrial use it’s probably a bit risky to transport and is defined as UN 1969, which is not allowed.

The Isobutane+propane mix, broadly defined as UN 2037, in the cartridges we use (UN 2037) are clearly defined as small containers, which have lower pressure and not refillable, so risk should be low, hence allowed.

Thanks Limor for digging more into it, hopefully this is going to help BC Ferries updating their policies.

P.S. Don’t quote me on this one, I’ve got some AI help 😉
