Good question! The transportation section of your MSDS for dry caffeine will provide the proper hazard classification. The manufacturer should be able to provide the MSDS to you.

Dual UN markings on packaging, while not seen very often, do occur for a variety of situations. Due to the fact that the UN marking signifies the specifics of the package (gross mass, packing group, or even country of manufacture) companies will often use dual markings to cover their bases on packages that are used in more than one way.
For example, we have packages that we place both UN markings on for Packing Group I and Packing Group II. The reason behind this is that the Packing Group I materials used in the package are typically at a lower specific gravity than the Packing Group II. By testing the package at 2 different specific gravities, we can let our end users know the gross mass acceptable for each case.
In your specific example, a dual marking for US and Canada would lead me to believe that the company manufacturers the package in two different countries (Toronto, Canada and Niagara Falls, NY for example). By putting both marks on the package, they can sell this carton in both countries without having to worry about an error in printing/embossing. I have never seen a package with dual country markings on it, though, because you can use packaging from another country without issue.
There could be different test criteria in the US and Canada. It is advised to have each UN certification on file (from both countries). I could go into more detail or research some more specifics if you could let me know a little more about your situation. You can contact me at Mike.Thompson@BerlinPackaging.com if you would like to discuss this more.
