If you are exporting goods to an African country, there is one document you simply cannot afford to overlook — the CNCA (Certificat de Navigation/Conformité et d’Arrivée) or ECTN (Electronic Cargo Tracking Note). This certificate is mandatory in most African nations, and without it, your shipment cannot be legally cleared at the destination port.
What exactly is CNCA/ECTN?
In simple terms, CNCA/ECTN is an officially verified summary that bridges two critical shipping documents: the Bill of Lading (BL) and the Import License (also known as DU — Document Unique). Think of it as a cross-verification certificate that confirms the shipment details on both documents match and are authentic.
This document is issued by a government-authorised body and forms the cornerstone of import legalisation in many African markets, including Angola, Benin, Cameroon, and the Congo Republic.
Step 1 — Apply for the Import License / DU
Before any goods arrive, the importer in the destination country must apply for a DU (Import License) from their government. This license discloses full shipment intent and must include:
|

Note: The shipment must be completed within the
validity period stated on the license — plan your cargo timelines accordingly
Step 2 — Issue the Bill of Lading correctly
The BL is the second pillar of CNCA. It must accurately carry the following information:
|
BL Field |
BL Field (continued) |
|
Shipper details |
Consignee details |
|
Notify party details |
Port of loading & discharge |
|
Product HSN code |
Product description |
|
Gross & net weight |
CBM / Measurement |
|
Freight condition |
Voyage number & vessel name |
|
BL number & date of issue |
Container number & seals |
Step 3 — Obtain the CNCA/ECTN certificate
With both documents ready, the CNCA/ECTN application can be submitted. The certificate consolidates all key information into one verified record:
• Shipper & consignee names
• Port of loading & discharge
• Vessel name & voyage number
• Shipping line & country flag of vessel
• Gross weight & volume (CBM)
• Freight value
• Container & seal numbers
• Product description
• BL number
• DU/Import License unique number
• Issuing authority signature & date
Why CNCA/ECTN cannot be duplicated or faked
The moment a CNCA number is entered into the government system, the full shipment details become visible instantly to the authorities. The document is also verifiable via barcode online, making forgery effectively impossible. Once authenticated, amendments are not permitted without either a formal cancellation or written approval from the Ministry of Commerce.
Critical Timing Tip for Exporters
You typically have only about one week between cargo loading and vessel sailing to finalise and amend your BL. Once the vessel has sailed, any BL amendment carries a penalty. Finalise your BL before sailing — then apply for CNCA/ECTN any time before vessel arrival at the destination port.
A note on BL and CNCA cross-referencing
Some shipping lines include the CNCA/ECTN number directly on the BL to formally link the two. However, the more common and practical approach is to mention the BL number on the CNCA/ECTN certificate instead — as the CNCA can be applied for after the BL is finalised and before vessel arrival, giving exporters greater flexibility without risking BL amendment penalties.
Key Takeaway
For any export to Africa, build CNCA/ECTN into your pre-shipment documentation checklist. Get your BL right the first time, apply for the certificate before vessel arrival, and ensure your import license validity covers your shipping window. Getting this right saves you from port delays, penalties, and costly amendments.
