You should - many regulators around the world are modeled after FCC. When I was doing regulatory test work for RFID readers (which were transmitting at 1W ) IIRC Canada, Korea and Japan were very similar to FCC.

Additionally - if you are in Europe - regulations are defined by a body called ETSI (https://www.etsi.org/). For RFID these regs were quite different from FCC - we had to do listen before talk and a variety of other things to ensure compliance.
