The UNECE TIR Secretariat proposes to TIR stakeholder on the field the following 2 mobile applications available both on Apple App Store and Google Play:

The benefits from the use of the electronic TIR procedure, the eTIR international system, are multiple for all the stakeholders...
Is your Customs Authority ready to join the eTIR International system?
Then contact the TIR secretariat to start the interconnection project.
The eTIR system offers benefits to all actors involved in the TIR system.
First, it brings additional security and risk management opportunities, thus reducing the risk of fraud.
Second, advanced international cooperation will allow all actors to significantly reduce their administrative burden and to maximize the benefits of integrated supply chain management.
Finally, the provision of advance cargo information and the exchange of information in real-time will speed up the TIR procedure.

This document describes the I1 - Accept guarantee request message, and the I2 - Acceptance results response message of the eTIR international system web services.
