They may say that, but I bet they comply - it means if your competitor
finds out that you don't comply you have problems.  I've never worked
anywhere where it's not taken seriously.

 In europe, "taking seriously" often means buying a reel of CE stickers
and slapping them on everything.
 Did you EMI lab test everything that you sold?
 

I have never seen any developers in Europe sell products that are not tested and compliant.
I have seen many Chinese products that fails testing, but also seen Chinese products that comply with very ingenious solutions.

We mostly sell things that go onto bigger systems, and our customer
worries about certifications. So we only need to not make them fail.
Our box could be buried deep inside their system.
 

Right, that's the differentiation. You do not need to test products that go into a system, just as long as the complete unit complies.
But, if it fails, it can be hard to find out which one of the sub assemblies are the root cause, and time is money
