TIR Carnet
The TIR Carnet is the customs document at the heart of the TIR system (from the French Transports Internationaux Routiers), which allows goods to be transported by road across multiple countries under customs seal with duties and taxes suspended, and with minimal inspection at each border. It is one of the most successful international customs transit regimes, operating under a UN convention across dozens of countries in Europe, the Middle East, Central Asia and beyond.
Under TIR, goods travel in sealed, approved vehicles or containers, accompanied by the TIR Carnet, which serves as proof of an internationally valid customs guarantee — so that duties at risk are covered without each country demanding its own security. Customs at intermediate borders simply check the seals rather than re-examining and re-bonding the cargo, dramatically speeding cross-border road transit and cutting cost and delay. The TIR Carnet is a cornerstone of efficient international road freight and transit corridors, closely related to the CMR (which governs the carriage contract) and to customs transit generally. It is essential to long-haul cross-border trucking across the regions that use it.
Without TIR, a truck crossing several countries would face duties, inspections and separate guarantees at every border — TIR replaces all that with one sealed load, one guarantee and a quick seal check, transforming cross-border road transit. It is the backbone of long-haul international trucking corridors and a model of how customs transit can make trade flow.
How does the TIR system work?
Goods travel in sealed approved vehicles under a TIR Carnet that provides an internationally valid customs guarantee, so borders check seals rather than re-inspecting and re-bonding the cargo.
How does TIR relate to the CMR?
TIR handles customs transit across borders; the CMR governs the road-carriage contract and liability. They often apply together on international road freight.
