Along with the Bill of Lading, the commercial invoice represents one of the most important documents in the Cargo Tracking Note application. The obligation carries significant complexity, as numerous key details must satisfy official requirements and align with other supporting documents.
"The importance of correct Invoices can't be undermined as it may lead to a successful CTN application, refusal, or even rejection."
CTN stands for Cargo Tracking Note, a system implemented across 27 African countries and referred to as BSC, CNCA, FERI, BESC, ECTN, or BIETC depending on the country.
Where the invoice falls in the order of events — draft first, then payment, then validation — is timed in an Angola ARCCLA case study with the invoice step recorded.
Primary Details Required on the Invoice
Unless otherwise specified, invoices submitted for the waiver certificate must include:
- The total FOB value clearly shown and equal to the sum of all product rows
- A compulsory incoterm, with additional costs displayed based on the shipping agreement:
- FOB: Ocean freight cost excluded; present invoice separately if applicable
- CFR: FOB and freight costs stated separately
- CIF: FOB, freight, and insurance all included
Acceptable Currencies
Invoices may be submitted in any currency, though the CTN system accepts only selected currencies with conversions applied at current exchange rates.
Cross-Trade Shipment Invoices
When three parties are involved, two separate invoices are typically raised. For cross-trade or triangle transactions involving a manufacturer, reseller, and consignee, use the invoice issued from the reseller to the importer in the destination country.
Personal Effect Shipments
Authorities require a Proforma Invoice for personal or charity cargo CTN certificates. The estimated goods value need not reflect market value.
Country-Specific Invoice Requirements
Madagascar & Ivory Coast: Mandatory details include HS Code, incoterm, country of origin, and payment method.
Libya: The commercial invoice must be approved by the Chamber of Commerce in the origin country before filing a CTN application.

Top 3 causes of Madagascar BSC refusals
- The shipper or consignee is not registered on GasyNet’s system, so no draft can be issued.
- Weights, package counts or descriptions differ between the Bill of Lading and the packing list.
- Incomplete invoice information or a missing required document: GasyNet’s admissibility check refuses the BSC.
