Does the Lucid-ID requirement apply to you as a UK seller?

Yes, definitely. The VerpackG makes no exception for UK sellers — it applies to every business worldwide that imports packaged goods commercially into Germany or distributes them there. Brexit changed your status: you are no longer treated as a 'domestic' manufacturer, but as an importer. This means you bear full responsibility for VerpackG compliance, not your supplier or fulfilment partner. So if you sell products to Germany via Amazon, eBay or your own shop, you must be registered in the LUCID register. The Packaging Act makes no exceptions for small sellers — it applies from your first sale.
