How Does T1 Transit Work?

How does T1 transit work?

T1 transit is a customs procedure that allows non-Union goods to be transported through the customs territory of the European Union or the United Kingdom without having to pay duty and VAT in every transit country — the charges are only settled at the office of destination. The transit declaration is opened and closed in the NCTS system, and the goods must reach the specified office within a set deadline, secured by a customs guarantee. The T1 procedure is especially useful for movements between the United Kingdom and Poland, when the goods pass through the territory of other EU countries.
