as far as I know, Luxfer has fulfilled the requirements for both the DOT exemption and Pi certificate. Tanks are not certified when they leave the production line - the whole production proccess is subject to an inspection from time to time, and end products are checked out periodically.
As long as the tank has both the DOT Exemption and the Pi certificate on the sticker - it's good to use in both the US and EU. The thing is, that Luxfer didn't get the pi certification on their own. The rumor is, that it has been partially paid for by PMI in exchange for an exclusive dealership contract, as only they have those pi/DOT tanks on sale (Pure Energy).
I'll try to find you a picture of one with both the pi and the DOT.
