I wasn't talking about sourcing parts, OP was talking about certification for sales in the EU which I think can be sidestepped selling as a kit of disparate electronic parts. I can receive Mouser shipments from the US to Germany, for example, as long as they're not development boards (which require a declaration of usage) or certain batteries.

I can't imagine why OP would be unable to ship those parts as a kit if they so chose.

I don't see that either. There is nothing legally grey about shipping kits. There is about shipping a finished product and marking it as a kit.
