TIR is an international customs transit system established under the TIR Convention. It allows approved road vehicles or containers to move goods across several customs territories under customs control, normally with a recognised guarantee and customs seals. It simplifies transit formalities; it does not remove export, import, safety or product-specific requirements.
TIR is not mandatory for every road shipment
A TIR Carnet may be used when the route, customs offices, vehicle or container, holder and national procedures support the TIR system. Other transit procedures may be used instead. The correct regime is selected by the responsible customs professionals according to the shipment and route.
How a TIR movement works
- The authorised holder obtains a valid TIR Carnet and prepares the transport and customs information.
- The goods are presented at the customs office of departure, where controls may be carried out and the load compartment may be sealed.
- At intermediate borders, customs generally checks the carnet, seals and vehicle rather than requiring a complete new transit guarantee.
- The goods and carnet are presented at the customs office of destination, where the TIR operation is terminated or discharged according to the applicable procedure.
Key conditions
- The carnet holder must be authorised and the carnet must be valid for the operation.
- The vehicle or container must meet the applicable approval and sealing conditions.
- The cargo description, package count, weight, customs offices, route and vehicle information must be accurate and consistent.
- Customs seals must remain intact unless opened by an authorised authority and properly recorded.
- The carnet and movement must be handled within the Convention, national law and instructions of the competent customs authorities.
Who is responsible for what?
The TIR holder is responsible for proper use of the carnet and compliance with the procedure. The carrier and driver must protect the cargo, documents and seals and follow authorised instructions. Customs authorities retain the power to inspect, require documents, change routing conditions or refuse release. The guarantee chain covers qualifying customs duties and taxes within the system’s rules; it is not cargo insurance.
Common causes of delay or irregularity
- Inconsistent invoice, packing list, CMR or carnet data.
- Incorrect customs office or route information.
- Damaged or missing seals, or unrecorded opening of the load compartment.
- Vehicle or container approval problems.
- Goods requiring licences or controls not completed before departure.
- Failure to present the carnet for proper termination at destination.
Good operating practice
Prepare the customs file before loading, compare every document against the physical cargo, photograph seals and load condition, record any official opening, and confirm discharge at destination. A TIR movement should never be described as automatically faster or inspection-free.
