Yet they are:

I suspect that's simply because no country uses both the ISO B and JIS B series, so there's not need to tell them apart usually.

I am not so sure that printer models are the same everywhere (let alone paper trays).

> I think we should get more information on what actually happens in the current infrastructure before adding these additional labels. One thing to do would be to measure the actual size of 'B4' and 'B5' on printer trays in various countries (Europe, US, Japan).

We could do that, but I don't think there is much doubt about the fact that:
* The B series is in common use in Japan
* The B series used in Japan is the JIS one

Here are two extra source, and google will produce many more if asked:
