What’s the difference between a T.I. and a URN number?

T.I. is a component of the GUOT document, which serves as an import declaration in the Republic of Congo. Therefore, to apply for ECTN, a supporting document called the T.I. is necessary.

The URN number is a reference number for the Republic of Congo’s ECTN certificate. It is printed on the ECTN certificate that has been verified.

Can I apply for the Republic of Congo ECTN if the container has been put on board?

You may apply for an ECTN certificate for the Republic of Congo after you leave. Please note that if the certificate is not validated within 5 days after the onboard date, authorities will assess a penalty in addition to the certificate fees. 50% of the price of the original certificate is the fine.

Are the procedures different between the Republic of Congo and the Democratic Republic of Congo?

Yes, they are two different countries, and their systems are different.

Where can I find the URN number on the Congo ECTN?

The URN number on the ECTN Congo certificate is listed as the “Visum Reference No.” The URN typically starts with an exporter country code and is made up of a combination of digits and letters. This number is located in the top-right corner of Congo ECTN.

What are DI and T.I. documents in GUOT? Which one is needed for the ECTN?

GUOT has two documents: TI (Transport d’importation) and Douane d’importation (DI). The importer in the Republic of Congo is required to issue both certifications. The applicant must submit just T.I. (Transport d’importation) to receive an ECTN certificate. On the GUOT paperwork and the invoice, the goods value and freight value must match.

Can I use the same ECTN number for various shipments?

No, ECTN is unique and limited to a single shipment. Every cargo needs its own ECTN number that has been verified.
