Case Study: Correcting CBM Volume Discrepancies on a Madagascar BSC (ECTN) Application
The Packing List said 260 CBM, the Bill of Lading said 240. Either figure alone would have passed; together they are a rejection. This case study shows how a cross-document audit caught the gap before filing and kept eight containers moving to Tamatave.

Synchronizing volumetric data for raw material exports to Tamatave. Discrepancies in cubic meter (CBM) volume between an ocean Bill of Lading and a Packing List will trigger an automatic rejection from customs authorities. This case study details how our pre-screening audit identified a CBM mismatch on an eight-container shipment of raw materials traveling from Salalah, Oman, to Tamatave, Madagascar, guiding the exporter through document alignment to secure an approved Bordereau de Suivi des Cargaisons (BSC).
We recently managed the cargo tracking documentation for a large-scale shipment of raw materials departing from the Port of Salalah, Oman, and bound for the Port of Tamatave, Madagascar. The shipment was packed into eight 20-foot dry containers. Under Madagascar maritime regulations, all sea imports require a validated Bordereau de Suivi des Cargaisons (BSC) certificate prior to discharge and customs clearance.
The Document Audit
To initiate the BSC registration, the exporter provided the full suite of mandatory documents required by the authorities. During the initial review — before creating the certificate draft — our compliance operator conducted a cross-document data audit rather than checking each file in isolation.
The Discrepancy: 260 CBM on One Document, 240 on Another
The operator discovered a significant volumetric error. The Packing List recorded a total volume of 260 CBM across the eight containers, whereas the ocean Bill of Lading listed a total volume of 240 CBM.
Neither figure is wrong on its face — the problem is that they contradict each other. Submitting files with conflicting volumetric data results in an immediate application rejection and administrative delays.
The Fix
Catching the discrepancy before official submission, our operator contacted the client to flag the mismatch. We explained that Madagascar authorities require complete data alignment across all paperwork.
We instructed the exporter to verify the actual loaded volume with their freight forwarder and issue a revised Packing List matching the 240 CBM figure stated on the final Bill of Lading.
The Result
The exporter coordinated with their logistics team and promptly provided an updated Packing List with the synchronized CBM measurements. Our operator re-audited the entire document package, verifying that all weights, volumes, product descriptions, and values matched across all five mandatory files.
We finalized the BSC draft, received client approval, and submitted the package to the authorities. The official Madagascar BSC certificate was approved and issued without query, preventing port clearance delays and demurrage charges at Tamatave.
Key Takeaway
A CBM figure that is correct in isolation can still sink an application. Madagascar’s authority does not assess the Packing List and the Bill of Lading separately — it compares them, and a 20 CBM gap between two mandatory documents reads as unreliable data rather than a rounding difference. The volume, weight, description and value on every file have to tell the same story before anything is filed. Reconciling them during document control, rather than after a rejection, is what keeps eight containers off a demurrage clock.
