We import goods from the EU, normally on driver accompanied or unaccompanied trailers. We want to register for the Transitional Simplified Procedure (TSP) but we understand that there are limitations on certain types of goods. I have seen mention of “controlled goods” — do you have any more specific information on what controlled goods are? We import goods that could come under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) controls, eg clothing accessories with feather, leather, etc. Also, will TSP operate at all ports in the UK?
