The CE Mark
The CE mark is an unverified promise by the inside-the-EU manufacturer ... or the inside-the-EU importer. It promises that the item complies with EU safety standards.
It is not anything like UL, CSA, TUV, etc. - those are independent testing labs and their staff has actually run a specimen of the product through a battery of tests, everything from overloads to flame-testing (for toxic substances) to sourcing of components.
You're the importer. You're responsible.
Anyway, when you buy via Amazon/ebay/Ali, you are importing this into the EU. So if it has the mark (obviously, it's counterfeit), you are agreeing to test it according to CE standards (and of course it will fail).
If it does not have the CE mark, then it's illegal to install it, unless it has the mark and listing number of a proper testing lab like TUV.
Amazon is a slippery one, because they seem like a domestic mail-order supplier like Wickes or Redoute who you would expect to be reliable. But Amazon intermixes into their listings something called Amazon Marketplace, which is a flea market of third party sellers peddling the cheapest junk in Shenzhen.
People confuse these "Marketplace" flea-market listings with listings actually sold by Amazon proper. The scammers write a bunch of fake reviews*, and often charge similar prices to quality domestic goods, and people buy it because they think the high price means quality product. They've really got it down.
The products Amazon buys for their own internal sale are usually high quality normal goods like you'd get from Wickes.
If you find a proper UL listing or equivalent, then you can install it. Due to treaties, a CSA listing on a US product is honored in the EU. (again CE isn't anything, but a TUV listing from a German product is honored in the US). So it's not uncommon to find EU color codes (brown/blue) in the US or US color codes (black/white) in the EU.
Black is hot and should be taped brown (not critical).
White is neutral and should be taped light blue.
* They get "verified sale" on their reviews thusly: Initially they direct-ship the items, place hundreds of orders from sockpuppet accounts, don't actually ship the item, collect the payment from themselves (eating Amazon's cut), then write a glowing 5-star review of themselves. Then with their 4.7 star rating, they place it in Amazon Fulfillment so it's drop-shipped from an Amazon warehouse.
