There's no such thing as a Chinese Export or China Export mark, it's an urban myth (see your own link).

Whether or not it exists seems to be mostly a matter of interpretation. Is the incorrect mark just a misprint while Chinese products with the correct mark are just as likely to fail to meet EU standards? Either way, that cheap products from China regularly fail the standards does not seem to be disputed by anyone. And if those products are sold in the EU, it's fairly easy to address, but if they're sold in China and mailed to the EU, it's not so easy to enforce. The problem remains the same, whether or not you see it as intentional or not.

It's the difference between deliberate (creating a confusing mark to legalistically "bypass" CE regulations - this is the myth) and negligence (China not bothering to enforce the standards set by other countries or even its own quality and safety standards - this is well known).

Germany seems to care more than other EU countries about such things like CE. They don't have trouble turning away imports based just because it's shipped to private customers.

Just ask people trying to receive PinePhones in Germany.

You don't have a german manual? Bye bye, try again later.

Similarly the UL logo and ETL Intertek logo serve the same purpose in the US. If something doesn’t have a UL logo it’s probably not safe.
