Cargo Tracking Note: What It Is, Who Files It, and What Every Destination Requires

Last updated: September 6, 2026

A cargo tracking note is a mandatory electronic certificate destination customs require before a sea shipment arrives. Filed by the shipper or forwarder, it registers the Bill of Lading, invoice values and freight against a reference number that clears the cargo.

What a cargo tracking note is

A cargo tracking note is a pre-arrival declaration. Before the cargo reaches the destination port, the shipping documents — Bill of Lading, commercial invoice, freight and insurance values, HS codes, shipper and consignee identity — are submitted to the destination country’s shippers’ council or customs authority. The authority checks the data, registers it, and issues a certificate carrying a unique reference number.

That number is the point of the whole exercise. It ties a physical container to a declared value and a declared consignee before anyone at destination can change the story. Customs at the discharge port reconciles the manifest against the registered certificate. If there is no certificate, or the numbers do not reconcile, the cargo is not released.

Why the requirement exists

  • Revenue protection. Import duty is assessed on declared value. A certificate filed at origin, before the goods are anywhere near the destination customs officer, makes under-declaration harder.
  • Trade statistics. Shippers’ councils use the filings to measure import volumes, freight costs paid out to foreign carriers, and route dependency.
  • Security and manifest control. Advance cargo declaration regimes — Sudan, Yemen, Kenya, Egypt — exist primarily to screen consignments before loading rather than to price them.

The certificate is a customs prerequisite, not a shipping document. It does not replace the Bill of Lading, the certificate of origin or an import licence. It sits alongside them.

The many names for the same certificate

The document has a different name in almost every jurisdiction, which is why importers so often believe they are dealing with several unrelated requirements. They are not. Each entry below is a variant of the same instrument — the full abbreviation breakdown is on what does CTN stand for.

The filing lifecycle

The sequence is the same in every jurisdiction. What changes is the cut-off.

  1. 1
    Booking confirmed
    As soon as the vessel and routing are fixed, the destination requirement is known. Check whether the discharge port is the final destination or a transit point — several countries treat landlocked transit cargo differently, and the routing has to be documented from the start.
  2. 2
    Draft Bill of Lading issued
    The draft BL provides the container numbers, seals, weights, vessel and voyage. Most authorities accept a draft to open the file. Almost none accept a draft to close it.
  3. 3
    Submission — draft back in 3–6 hours
    The Bill of Lading, commercial invoice and any country-specific documents go to the authority or its appointed agent. The data on the submission has to match the documents exactly, not approximately.
  4. 4
    Validation — 3–6 hours once approved and paid
    The authority reconciles the declaration against the documents and, where it has access, against the carrier’s manifest. Queries are raised here, and every query costs time the vessel is not waiting for.
  5. 5
    Certificate number issued and placed on the Bill of Lading
    For most destinations the number must appear on the Bill of Lading itself — on the face of it, in the cargo description, or on the master BL specifically.
  6. 6
    Arrival and clearance
    The consignee presents the certificate at destination. Angola is the notable exception in requiring the original hard copy to be couriered to the importer; most destinations accept an electronic copy.

Who is legally responsible

The shipper, or the freight forwarder acting for the shipper. Not the consignee, and not the carrier.

This surprises exporters who assume a destination-country requirement is the destination-country importer’s problem. It is not. The certificate is filed at origin, from origin documents, and the penalty for a missing certificate is levied on the cargo — which means it lands on whoever is trying to release it, and then contractually back on the shipper.

  • Egypt (ACID). The Egyptian importer registers on the NAFEZA portal first and obtains the ACID number. The foreign exporter then completes the filing and quotes the number on the Bill of Lading and commercial invoice. Neither side can finish alone.
  • Advance cargo declaration regimes (Sudan, Yemen). The reference must exist before loading at the origin port. Responsibility sits with the shipper by definition, because after loading there is no compliant path.

Where an importer needs a prior national document — Angola’s Documento Único, Ivory Coast’s and DR Congo’s FDI, Madagascar’s GASYNET registration — the importer must obtain it, but the shipper cannot file without it. Confirm it exists before the vessel is booked.

Deadlines: when the certificate is due

Cut-offs are set per destination and are revised by the authorities without much notice, so the anchor matters more than a memorised number. Filing at booking is safe everywhere.

  • West and Central Africa (BESC, BSC, ECTN, FERI, BIETC, CEE). The recorded anchor for most of these destinations is validation before the vessel arrives, with filing at booking strongly preferred. Liberia and Republic of Congo are recorded against sailing rather than arrival.
  • Angola. Validation anchored to arrival, and the importer must present the original hard-copy certificate to release the cargo. Courier time has to be built into the plan.
  • Advance cargo declaration regimes (Sudan, Yemen). The reference must be obtained before loading at the origin port. There is no retrospective filing.
  • Egypt (ACID). The ACID number is registered before the cargo is shipped and must be printed in the body of the Bill of Lading.
  • East Africa (Kenya ACD). Documents submitted after the vessel departure deadline are rejected.

Because the anchors are route-dependent, confirm the cut-off for your specific voyage rather than working from a general rule. Every country page states the position for that destination.

Validity and amendments

A validated certificate is issued against one shipment: one Bill of Lading, one vessel, one voyage, one consignee. It does not carry over to the next shipment and it is not a licence with a renewal date. If the shipment changes, the certificate has to change with it.

What can be amended after validation, and at what cost, is set by each authority. Some restrict amendments outright; most charge for them. Where a prerequisite national document has its own validity — Angola’s Documento Único, for example — that document’s expiry governs whether the filing can proceed at all, which is why we check it at the start rather than at validation.

What happens without a valid certificate

The general pattern, wherever you are shipping: a fixed or multiplied fine at the port, plus demurrage and storage accruing daily while the cargo sits undeliverable. The fine is usually the smaller number. Use the demurrage calculator to size the second one before deciding whether a filing is urgent.

  • Cargo not released. Angola requires the original hard copy before release. DR Congo cargo may be held at Matadi or Boma until the FERI and related taxes are settled.
  • Percentage-of-value fines. Cameroon fines for a missing or incorrect BESC can reach 30% to 50% of the CIF freight value, plus storage and demurrage at Douala.
  • Multiples of the certificate cost. Angola applies penalties of twice the certificate cost, plus standard regulatory fines, for shipments arriving without a validated CNCA or with false declarations.
  • Return to origin. Cargo reaching Egypt without a valid, matched ACID is refused customs release and returned to the origin country at the shipper’s expense.
  • Refusal to load. Sudan and Yemen check the reference at the load port, so cargo without one can be stopped from shipping at all.

Required documents

Three documents are the minimum for almost every destination: the Bill of Lading and the commercial invoice everywhere, and the freight invoice in 29 of the 30. Everything else is a country variation.

Cost structure

Every quote has two lines. 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 destination’s published requirements, filing it and handling queries.

Both lines are fixed and shown before anything is filed, so the invoice you approve is the invoice you pay. Amendment charges, where an authority allows amendments at all, are quoted separately at the time.

Frequently asked questions

A cargo tracking note is an electronic certificate that destination customs authorities require before a sea shipment arrives. It registers the Bill of Lading, declared values, freight, HS codes and consignee details against a unique reference number, which customs reconciles against the vessel manifest before releasing the cargo.

Yes. They are regional names for the same instrument. ECTN is the general English term, BESC and BSC are the French-speaking West and Central African forms, FERI is used in DR Congo, BIETC in Gabon, CNCA in Angola, CEE in Guinea Bissau, and ACD or ACID for the advance cargo declaration regimes of Sudan, Yemen, Kenya and Egypt.

The shipper, or the freight forwarder acting for the shipper, filing at origin. The consignee is not responsible, with the partial exception of Egypt, where the Egyptian importer must first register on the NAFEZA portal to generate the ACID number before the exporter can complete the filing.

The cut-off is set per destination. Most destinations we file for are anchored to vessel arrival, Liberia and Republic of Congo to sailing, and Sudan, Yemen and Egypt require the reference before loading at the origin port. Filing at booking is safe everywhere; we confirm the exact cut-off for your route.

Every destination requires a Bill of Lading and a commercial invoice. Beyond that, five destinations require a packing list, Sudan and Yemen require a Certificate of Origin, Gabon a customs declaration, Egypt a cargo declaration, and Angola, Ivory Coast, DR Congo, Madagascar and Niger each require a national prerequisite document.

The most common ground is the certificate number missing from the Bill of Lading. Next come freight and insurance not shown separately from FOB, value mismatches between the invoice and the customs declaration, and weight or package discrepancies between the Bill of Lading and the packing list.

The cargo is not released. Most destinations apply a fine set as a multiple of the standard certificate fee, and demurrage and storage accrue daily while the container sits undeliverable. Egypt returns cargo arriving without a valid matched ACID to origin at the shipper’s expense.

A draft certificate and a fixed-price invoice come back within 3–6 hours of receiving your Bill of Lading and commercial invoice. Validation takes a further 3–6 hours once you have approved the draft and settled the invoice.
