I work as a certification engineer for a 'notified body' so I guess I'm qualified to answer.....
The CE mark is NOT a safety mark - not at all..! There may be safety aspects associated with the product but not necessarily
My question to the helmet guy (because I also own a motorcycle factors) is
who said the helmet was non-compliant, and how did he know this?
for helmets to be used on the roads in this country, the road traffic act requires them to have either a kitemark or an E13 (EU safety standard) mark. This is in addition to the CE mark. Did the helmet have these? Perhaps someone is confusing the E13 mark with the CE mark?
trading standards 'police' the CE mark in this country - if you buy a product without a CE mark then you need to inform them. They can and will prosecute.
Not all products require CE marks
this site will tell you all you need to know - and you can get most of the directives (the rules/law for EU products) free from the same site.

finally - what is the CE mark? It's a mark which must be applied to products (as required - see above) so that they can be legally sold in the EU
no mark - no sell
the manufacturer declares that his product complies with the relevant EU directive.
Testing may or may not be required, and the manufacturer may or may not be able to do the tests himself
