Just tested in Hungary.

I just checked the boxes of some of my USA made ammunition:

Winchester 12 gauge "Super Targets" and 20 gauge "Universal" are CIP tested in Liege, Belgium.

A box of Remington 12 gauge was CIP tested in Munich, Germany.

At least some USA manufacturers submit ammunition to a CIP proof house for testing. I believe that if they want to sell their ammunition in a CIP signatory country it must be CIP tested.
