What is the Liberia CTN (BESC)?
The Liberia CTN is the cargo tracking note the National Port Authority (NPA) requires for shipments to Liberian ports: Monrovia, Buchanan, Greenville and Harper. Each Bill of Lading needs its own validated number, written on the Bill of Lading and in the cargo manifest. Carriers announced the requirement for shipments from 2019, cargo in transit through Liberia included.
The CTN is Liberia’s form of the cargo tracking note; CTN meaning in shipping explains the document 30 African and Middle East destinations ask for in one form or another.
Other names for the Liberia CTN
One instrument, several names. For Liberia the filing is the CTN — Cargo Tracking Note. The same certificate is also referred to as CTN (Cargo Tracking Note), ACD (Advance Cargo Declaration), ECTN (Electronic Cargo Tracking Note), and cargo tracking note, and a request for one is a request for the other. If your importer or your carrier has asked for a name that is not on this page, send it to us with the Bill of Lading and we will confirm which filing they mean.
Liberia CTN: Monrovia, Buchanan, Greenville and Harper
Liberia’s seaports are Monrovia (the Freeport of Monrovia), Buchanan, Greenville and Harper. The Liberia CTN is required for every Bill of Lading discharged at any of them, and carrier notices extend it to cargo that only transits Liberia.

When to get the Liberia CTN
Obtain the Liberia CTN before the vessel sails: cargo without a valid number is not loaded, and the number has to appear on the Bill of Lading. Under the measures in force since 16 May 2026, a shipment that sails without one has 14 days from the sailing date before non-compliance penalties apply, and amendments requested after the application has been submitted are charged.
Who files the Liberia CTN
The shipper, the exporter or the freight forwarder at the port of loading files the Liberia CTN. The consignee in Liberia does not file it, but the cargo cannot be discharged without it.
How to get the Liberia CTN, step by step
According to the customs regulations of Liberia, every cargo shipment purchased from abroad and transported for commercial, business, diplomatic, or personal purposes requires a validated Loading Certificate:
- ▪Send the Bill of Lading, the commercial invoice showing the FOB value, freight and insurance, the packing list, the freight invoice and the export customs declaration.
- ▪We check that packages, weights and values match across the documents and prepare the draft with the Liberia CTN number.
- ▪You approve the draft; the number is written in the cargo description of the Bill of Lading and in the manifest.
- ▪The validated Liberia CTN travels with the cargo for discharge and clearance in Liberia.
Liberia CTN: validity and amendments
A validated CTN is issued against one shipment: one Bill of Lading, one vessel, one voyage, one consignee. It does not carry over to your next shipment and it carries no renewal date. If the shipment changes, the certificate has to change with it — and what can be amended after validation, and at what cost, is set by the destination authority. Corrections to the draft before filing cost nothing, which is why we send you the draft first.
What happens without a valid Liberia CTN?
Cargo arriving without a validated CTN is generally not released at Monrovia: customs clearance delays, storage and demurrage accruing daily, and regulatory fines until a valid certificate is presented. The demurrage is often the larger of the two numbers, and it is the one that grows while the paperwork is corrected.
What the Liberia CTN costs
Two lines, quoted separately. The first is the statutory charge the destination authority sets for registering the certificate — it belongs to the authority, not to us, and it varies by destination and shipment profile. The second is our service fee for preparing the file, checking it against the published requirements, filing it and handling any query. Neither is a percentage of your cargo value. Both are fixed and shown before anything is filed, so the invoice you approve is the invoice you pay. How ECTN charges are calculated.
Liberia CTN: latest notices and articles
Is the Liberia CTN Mandatory?
Yes. Every sea shipment discharged in Liberia needs a CTN, and carrier notices extend it to cargo that only passes through. Cargo without a valid number is not loaded or discharged.
How Long Does the Liberia CTN Take?
Vessel departure sets the pace for Liberia. The file opens when the Bill of Lading, commercial invoice, packing list, freight invoice and export customs declaration reach us. Packages, weights and values are compared, the numbered draft comes to you, and after approval the number goes into the cargo description and the manifest.
An invoice without the FOB value, freight and insurance holds the file back, and so does a package or weight mismatch. The limit is sailing. Since 16 May 2026, a shipment that sails without a CTN has 14 days from the sailing date before non-compliance penalties apply.
Does Cargo in Transit Through Liberia Need a CTN?
Yes, according to carrier notices: the requirement reaches cargo that only transits Liberia. Since carriers do not load cargo without a valid number, a transit Bill of Lading needs its number ready too. Tell us the cargo is not staying in Liberia when you send it.
Where Does the Liberia CTN Number Go on the Bill of Lading?
In the cargo description field. The same number must also appear in the cargo manifest. Each Bill of Lading needs its own validated number, so two Bills of Lading on one vessel cannot share one.
What Must the Commercial Invoice Show for the Liberia CTN?
The FOB value, the freight and the insurance. If the invoice gives one total, ask for it again with those three items shown separately, since a missing breakdown is one of the top rejection causes for Liberia.
What the 14-Day Grace Period Covers
The 14 days run from the sailing date, not from arrival, and non-compliance penalties follow once they end. Carriers still do not load cargo without a valid number, so do not book without a Liberia CTN on the strength of this period.
When Do Liberia CTN Amendment Charges Start?
The line is the moment the application is submitted. Corrections to the draft before that cost nothing; since 16 May 2026, any amendment requested afterwards is charged. Compare weights, values and party details with the Bill of Lading and the manifest before you approve.
Your Consignee Asks for an ACD: Which Document Is It?
For Liberia, the document called the ACD (Advance Cargo Declaration) is the CTN, printed on the certificate as BESC. Those three names do not mean three applications: you need one document per Bill of Lading.
Shipping to Liberia from Turkey
Get the Liberia CTN before the vessel leaves Turkey, because the number has to be on the Bill of Lading and in the manifest. Declare the cargo type correctly: earth-moving machinery and large trucks on flat racks are invoiced under the RoRo tariff, not the container tariff.
Why File Through GetCTN
Since amendments for Liberia are charged once the application is in, we compare packages, weights and values before you see the numbered draft. The FOB, freight and insurance breakdown is checked at the same step, ahead of the number reaching the cargo description and the manifest.
