CTN Meaning in Shipping: What a Cargo Tracking Note Is

CTN stands for Cargo Tracking Note — the official loading document 30 African and Middle-East destinations require for customs clearance and cargo monitoring.

What is a CTN certificate?

A Cargo Tracking Note (CTN) is an official loading certificate that declares a shipment to the destination's customs authority before the cargo gets there. It contains detailed information about cargo and its movement between ports, including transit periods.

The CTN certificate must accompany any shipment to the countries that demand it, and the filing deadline depends on the destination — some require it before the vessel departs, others before the cargo arrives. It enables destination port authorities to have all necessary information before shipments arrive, facilitating customs clearance.

What does CTN mean on a packing list?

On packing lists, purchase orders and warehouse documents, CTN is shorthand for carton, a packaging unit: "10 CTNS" means ten cartons. That CTN has nothing to do with the cargo tracking certificate described here. How to tell the two apart on your shipping documents.

Which countries require a CTN?

Thirty African destinations require a cargo tracking certificate, and three of them call it a CTN. Elsewhere the same requirement runs under a local name — BESC across much of Francophone West Africa, ARCCLA in Angola, FERI in DR Congo, BIETC in Gabon, BSC in Senegal, Ivory Coast and Madagascar, ACID in Egypt, ACD in Sudan, Kenya and Yemen, CEE in Guinea Bissau.

These are the destinations where the certificate is named CTN. The third column restates the sources line of each country page:

Destination Certificate Body or legal basis (country page) Country page
The Gambia CTN Shipping line notice (Maersk, 15 May 2023) and the Ministry of Trade notification of 26 February 2026, as reported by Gambian press Gambia CTN
Liberia CTN Implemented by the National Port Authority (NPA) Liberia CTN
Sierra Leone CTN Ministry of Finance memorandum (Ref. MF-Rev 62/100/05/11-22), enforced through an accredited agency Sierra Leone CTN

For all thirty destinations and the name each one uses, see what countries require an ECTN.

Which documents do you need for a CTN?

Two documents are asked for at every destination we cover:

  • Bill of Lading
  • Commercial Invoice

Past those two the list is set by the destination and it varies — a freight invoice, a packing list, an export declaration or a country-specific application form may each be required. The country page for your destination carries its current list.

Why is the CTN certificate important?

The CTN gives the destination's customs authority a full picture of the shipment before it arrives, which is what lets clearance begin early. The certificate gives marine customs authorities access to:

  • Exporter and importer details
  • Shipping route and method
  • Commodity type and value
  • Freight value
  • Consignment details

Port authorities state that the CTN aims to achieve "substantial reduction of risk, real-time monitoring" and reliable assessments of import goods, shippers, and importers. The system also lets each country keep statistical data for future logistical monitoring.

What happens if you ship without a CTN?

Shipping or arriving without a CTN certificate may result in high fines at the destination port. The cargo cannot be cleared until a valid certificate is presented, so the hold adds storage and demurrage on top of the fine — which is why the deadline for your destination is worth confirming before the vessel books.
