What is the 'TIR' System?
"TIR" stands for Transports Internationaux Routiers (International Road Transport). It is an international Customs transit system that allows the goods to transit from a country of origin to a country of destination in sealed load compartments with Customs control along the supply chain. TIR is globally applicable, and uses a single international guarantee, thus eliminating the need for costly guarantees in each country of transit.
This allows transport companies and custom authorities to significantly cut down on time and money at the borders. The TIR guarantee covers the customs duties and taxes at risk, up to a maximum protection of EUR 100,000 per transport operation. Origin The TIR system was established to facilitate trade and transport whilst implementing an international harmonized system of Customs control. In 1949, shortly after World War II, the first TIR Agreement was concluded between a small number of European countries and led to the elaboration of the TIR Convention in 1954 under the umbrella of the United Nations Economic Commission for Europe (UNECE).
