In 2011 the Government of the Republic of Guinea-Bissau declared that all sea cargo destined for the Republic of Guinea-Bissau must have a Cargo Tracking Note (CTN) or Bordereau de Suivi de Cargaison (BSC). Some shipping lines may not load cargo without the CTN number. Cargo arriving without a Cargo Tracking Note may be subject of fines and delays.

Cargo Tracking Notes will not be issued at discharge port.


  • Submit the required documents by email or online submission.
  • You will be sent a draft and an invoice, typically within the same day.
  • Once your payment has been received and you approve the draft, validation will be sent.


  • The CTN must be validated before the vessel arrives at the destination. No regularization at destination port.
  • Since our office validates the CTN, the process can typically be done within 24 hours after receipt of payment.

Below are the required documents for this certificate:

– Bill of Lading
– Commercial Invoice
– Freight Invoice (required if the freight amount is not specified on commercial invoice)
– Customs Export Declaration
