It's an ETF, so it boils down to whether you have access to a particular stock exchange. European brokers support trading on US stock exchanges, so I'm sure it works the other way around too. I use Amundi and Xtrackers because they have large fund sizes, low TER, and that's what's available at the brokers I use, though not all of my brokers have Amundi, for example. The availability outside the EU shouldn't be a problem, since most funds are also at the London Stock Exchange in either USD or GBP.
