Hello, We are manufacturing trousers in Turkey, bringing them to the UK and then dispatching some to the EU B2B. As far as we are aware, the UK and the EU has a trade deal with Turkey putting the relevant HS codes at 0% duty. BUT, latest delivery to Italy, our UK DHL rep said that although there's a trade deal, due to the item going to the UK first, it's classed differently. It sounds like a load of rubbish to me but I may obviously be wrong. Where do I begin finding that out?
