I've always thought of them as thorough, and I wonder if someone has been a bit naughty with this fuse position. My reason for saying that is that some versions of the charger don't have a fuse there, but a live bare thin metal strip in the centre of a nylon plug a little further back. Like you I have three, and one is this version without that fuse position. That gives rise to the suspicion that perhaps that was the version submitted for testing.
This company supply many variants in the same case, so it's possible that could have happened, even accidentally maybe, the certification being taken as read for all versions. We do know other instances of somewhat cavalier Chinese approaches to standards in other areas of course, e.g. colour codes.
