Importing electrical items from outside EU - UKCA etc

[Timja]

Wondering if anyone has experience of importing electrical items from e.g. China

Thinking about importing a small qty of lighting items. I have only ever imported non electrical items before so after some advice on what is legally required to check they are safe and certified for UK electrical equipment safety regulations if I chose to resell.

They would be UK mains powered going to a 240v to 12v transformer which is CE/UKCA certified then some LED lights.

Does the finished unit need certifying or if the transformer is certified and stamped with CE/UKCA is this OK? Also does finished lighting unit need to have manufacturer /importer details on or only the transformer?

I think the regulations apply to 50V+, presume that relates to input power rather than output?

Anyone know and happy to share some knowledge or if for example the units need testing can anyone put me in touch with a company that does this?

Just trying to decide if it’s worth the effort e.g. if there is a lot involved as obviously want to ensure the lighting units are safe and comply to regulations which may be more involved than e.g. importing and selling a note pad!

Thanks
