The New Computerised Transit System.
The New Computerised Transit System (NCTS) is a system of electronic declaration and processing that traders must use to submit Union Transit (UT) and Transports Internationaux Routiers (TIR) declarations electronically. Paper declarations are only allowed when transit declarations can’t be made on the NCTS system or if travellers have goods in excess of their duty-free allowance.
The NCTS will process the declaration and control the transit movement. It’s used by all member states of the EU and the signatories of the Common Transit Convention.
The Common Transit procedure can also be used for movements between the EU and the Common Transit countries. These are the European Free Trade Association (EFTA) countries (Switzerland, Liechtenstein, Norway and Iceland) and Turkey, Macedonia and Serbia.
