There is a real contract supply legal issue with the way Amazon have set this up.
The seller pays Amazon for the shipping label, if amazon supply you with this label and bill you for this service then they are then contracting out to DPD. The sellers contract is with Amazon to supply the shipping service, Amazon subcontract DPD to supply the service.
Therefore if you were to test it in court then you’d likely be able to hold Amazon liable for non collection, loss of prime and subsequent loss of earnings resulting from this.
Not in anyone’s interest to do this clearly but again it just goes to show me that Amazon are all to quick to ride roughshod over the actual law and then hand the responsibility of the consequences of their actions back on to sellers.
Same with systematic Chinese VAT evasion on the platform, although I conceded that I also hold HMRC jointly responsible for this, would be easy for them to ask for batch sales lists quarterly from Amazon and reconcile this against VAT returns for said VAT numbers.
