Saw on a reseller FB group that eBay UK has turned off shipping to the States via their GSP. Went on their seller community boards and eBay said they were working on fixes due to tariff changes and would bring it back online when ready.
Of course no one really has any idea of what's going on there on the boards - all kinds of random uninformed opinions flying around. I imagine CN goods were coming over l, or goods with no clear CoO markings and getting refused by CBP and sent back to their UK hub, or worse getting hit with tariffs or fines.
More collateral damage, and more and more hopefully American buyers will start to realize how their choice and freedom to purchase is being ripped away from them.
