Looking at the chart posted on here, it appears that only the duty and quotas are aligned. Good because that stops all the counter duty stuff, like say, I tax your fish 10%, so you tax my wine 12%. Stops things spiralling out of control.
But country of origin and SPS checks look to be required. So in terms of supply, we would have to get a certificate from the chamber of commerce to prove origin, any dairy would require defra documents and a very expensive vet to be present to fill them out. Heat treated pallets are also still required as is my understanding.
Seems like they are playing to the crowd with the zero tariffs but considerable cost and time will still be added to supply. Government will still make a load of cash. But they will avoid all the hassle of negotiating duty. Win win for the government, cost of goods will still go up.
Is the way I read it anyway.
