You guys really know your stuff! Thanks.
Squiggle, I am norwegian. I got to choose from the two different types. I chose sesquihydrate ones because they're 100mg less APAP (they're 400/30). Strangely enough, the sesquihydrate ones contain the e161g color additive which'll produce a pink CWE mix. The e161g is banned in aus/NZ/EU/US bcause its known to cause retina failure, liver injury and an itching condition in humans - as if APAP/codeine doesnt cause enough complications...
Anyway, appreciate all the replies.
