Flatline info on the bottle

[ttp_fan]

Before I go and purchase a 68/4500, I need to know if there is a Transport Canada, (or TC) number on the bottle.
I was told at a local store that there HAS to be a TC number, similar to the DOT number on the bottle. Can someone let me know if there is such a number on every bottle, or just ones shipped to Canada.

Thanks

hmmmm.....

I was wondering what the deal was, the TC says rehydro every 3 years while DOT is every 5.
