1. Document preparation: the foundation of successful clearance
Clearance does not start when the vessel berths at Douala — it starts before cargo is loaded at the origin port (China, Europe, the Americas, etc.). Anticipation is the key to a smooth operation. To avoid delays, a complete file must be assembled and checked.
Here are the essential documents the importer must gather:
- Commercial invoice: detailed, stating Incoterms, currency, unit and total value of the goods.
- Bill of Lading (B/L): the ocean transport title proving the carrier took charge of the goods and authorizing delivery.
- Packing list: weight, volume, number of packages and exact packing of the cargo.
- Certificate of origin: essential to determine whether goods qualify for tariff preferences (bilateral agreements or AfCFTA).
- Import declaration (DI): mandatory for any import with FOB value of XAF 2 million or more, before shipment.
- BESC (CNCC): mandatory document; without a validated BESC, cargo cannot be cleared.
Our operational approach: we systematically ask partners to send us the full document set as soon as the vessel sails. This proactive step enables early checks, spotting inconsistencies and preparing the ground with administrations via GUCE.
2. Customs declaration via the CAMCIS system
Once the document file is validated and the goods have arrived, the most technical step begins: entering the customs declaration. By law, this is reserved strictly for licensed customs brokers.
Since the Cameroon Customs Information System (CAMCIS) went live, the whole process is digital. This phase assigns the goods their exact tariff classification (HS code — Harmonized System).
- Tariff position: an error may be seen as attempted fraud or undervaluation.
- Customs value: duties and taxes are calculated on the CIF value (Cost, Insurance, Freight).
- Document upload: digitized supporting documents attached to the declaration for inspector review.
We enter this declaration with rigorous precision, in full compliance with Cameroon customs requirements.

3. Customs inspection, assessment and payment of duties
As soon as the declaration is validated in the system, risk analysis assigns the file to a control channel:
- Green channel: full compliance, immediate release.
- Blue channel: deferred (post-clearance) control.
- Yellow channel: in-depth documentary check.
- Red channel: mandatory physical inspection at the yard.
If a physical visit is ordered, we arrange container opening with the customs inspector, stevedore representatives and, if needed, phytosanitary or standards services (ANOR). Once the check is validated, the inspector issues the assessment: exact duties, VAT, additional cents and related taxes. Duties and taxes are not negotiable. Real cost optimization comes from speeding up the process to avoid storage and demurrage — not from tariff fraud.
4. Obtaining the release note (BAE) and pickup formalities
As soon as payment of duties and taxes is confirmed via the banking system linked to CAMCIS, customs automatically issues the release note (BAE). This liberating document certifies that the administration no longer holds a lien on the cargo.
Logistics and commercial formalities then remain:
- Document exchange: present the original B/L to the carrier to obtain the delivery order.
- Handling: settle lifting and storage invoices with the terminal operator (e.g. RTC).
- Port dues: pay port charges to the Douala Port Authority (PAD).
Once the exit permit is issued, we coordinate truck positioning for loading so carrier free-time allowances are respected.
5. Transit to the hinterland: the CEMAC zone (Chad, CAR)
For goods bound for Chad or the CAR, the procedure falls under the International Transit regime (T1). Consumption duties are not paid in Cameroon: the goods cross the territory under customs control.
- Global bond: we put up our customs bond to guarantee the goods will leave the territory.
- Escort and tracking: trucks fitted with GPS beacons on the Douala–N'Djamena or Douala–Bangui corridors.
- Single Transit Title (TTU): accompanies the goods to the border office for transit clearance.

FAQ — Douala Port clearance & CEMAC transit
Import declaration, BESC, CAMCIS lanes, release note and T1 transit: practical answers to keep cargo moving.
When must the Import Declaration (DI) and BESC be issued to avoid delays in Douala?
- The DI (via GUCE) is mandatory for any import with FOB value of XAF 2,000,000 or more.
- The BESC (CNCC) is required for every ocean shipment to Cameroon. Without a validated BESC at departure, customs formalities are blocked and penalties apply on arrival.
ALC Transit approach: send us the file (invoice, B/L, packing list) as soon as the vessel sails. We check document consistency and prepare GUCE processing well before berthing.
How do CAMCIS control lanes (Green, Yellow, Red) work, and what happens on the Red lane?
- Green: compliance confirmed, immediate release.
- Blue: deferred control (post-clearance check after pickup).
- Yellow: in-depth documentary review by the inspector.
- Red: mandatory physical inspection of the container in the yard.
On the Red lane, as licensed broker we coordinate the on-site inspection. We attend the container opening with the Customs inspector, the stevedore (e.g. RTC) and any required control bodies (ANOR, phytosanitary services) so the cargo is validated without delay.
After duties are paid, how do I obtain the release note (BAE) and take cargo out of the port?
- Document exchange: present the original bill of lading (B/L) to the shipping line for the delivery order.
- Stevedoring invoice: pay handling and storage to the terminal operator (RTC).
- Port dues: settle port charges with the Douala Port Authority (PAD).
Once the exit pass is issued, ALC Transit positions trucks in the yard immediately for loading and delivery.
Are Cameroon import duties due on cargo bound for Chad or the CAR?
- Customs bond: we put our global guarantee in place with Customs to cover the transit.
- Single Transit Document (TTU): this official title travels with the load to the border.
- Geolocation: trucks carry GPS beacons for electronic escort on the Douala–N’Djamena or Douala–Bangui corridors until the file is acquitted.
How can I avoid demurrage and storage fees at Douala Port?
- Check that the invoice, B/L and packing list match before the vessel sails.
- Assign the correct HS code to avoid value uplifts or suspected misdeclaration.
- Have a responsive licensed broker file in CAMCIS, able to clear system rejections within 24 hours.
