What is Liberia CTN?
The CTN is a mandatory Electronic Cargo Tracking Note (ECTN) required for all sea-freight shipments destined for Liberia. It acts as a pre-shipment tracking and verification document: the destination customs authority uses it to reconcile the shipper, consignee, cargo description and declared invoice values against the Bill of Lading at Monrovia. The waiver must be obtained by the shipper or freight forwarder and validated within the destination's filing deadline — some countries require it before the vessel departs, others before it arrives. Presenting a missing, expired or incorrect CTN at destination typically leads to customs clearance delays, storage and demurrage charges, and regulatory fines until a valid certificate is provided.
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 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.
Which ports require the CTN
The requirement attaches to the port of discharge. For Liberia that is Monrovia. Where cargo only transits Liberia on its way to a landlocked neighbour, the routing has to be documented — several destinations treat transit cargo differently, so tell us the final destination when you send the Bill of Lading rather than after the file is open.
When to apply: the CTN filing deadline
The cut-off is set by Liberia and is anchored either to the vessel leaving the load port or to it reaching Monrovia. Filing when the booking is confirmed is safe under either anchor, and a draft Bill of Lading is enough to open the file. We confirm the exact cut-off for your route before anything is filed. Late validation costs more than filing on time everywhere it is allowed at all.
Who files the CTN
The shipper, the exporter, or the freight forwarder acting for them — the party at origin that holds the Bill of Lading and the commercial invoice. The consignee usually cannot fix a missing certificate from the destination side once the vessel has sailed. Where the sales terms put the cost on the buyer, that settles who pays; it does not move the obligation to file.
Official CTN Validation Procedure
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:
- ▪The shipper or freight forwarder is responsible for obtaining and validating the CTN within the filing deadline set by Liberia — before the vessel departs in some countries, before it arrives in others.
- ▪Prepare the mandatory documents for validation: Bill of Lading, Commercial Invoice, Packing List, Freight Invoice, and Export Customs Declaration.
- ▪Submit the documents to our compliance desk, where a senior officer cross-checks every field against the destination customs requirements.
- ▪Once validated, the CTN certificate is issued and must accompany the shipment for customs clearance at Monrovia.
- ▪File the CTN within the deadline Liberia sets — that date depends on the destination, and filing after it can trigger penalties and cargo-release blocks.
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 CTN
Cargo arriving without a validated CTN is generally not released. What follows depends on the destination: customs clearance delays, storage and demurrage accruing daily at Monrovia, 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 a 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.
