The Inspection Scope Said Full Cargo. The Surveyor Checked Half.
Quote from Guest on May 14, 2026, 4:32 amWhen inspection scope is narrower than the trader assumes, quality gaps go undetected until discharge. How partial inspections create disputes.
The trader appointed a surveying company for pre-shipment inspection on 35,000 MT of South African coal at Richards Bay. The scope specified sampling during loading, laboratory analysis for calorific value, moisture, ash, and sulphur. Fee: $14,500.
Loading took three days. The surveyor attended days 1 and 2. On day 3, the representative was reassigned to another vessel at the same port. The surveyor informed the trader's operations team by email that day 3 would be unattended and the sample from days 1 and 2 — representing approximately 23,000 MT — would be used for the certificate.
The certificate reported results from the 23,000 MT sample. It did not state the sample represented only two-thirds of the cargo. The format showed the vessel name, cargo quantity (35,000 MT), and analytical results. A reader would assume full-cargo representation.
The remaining 12,000 MT, loaded without supervision on day 3, came from a different stockpile with higher ash content. The discharge survey showed ash at 18.2% against a 17% maximum. The load port certificate showed 16.4%. The difference was concentrated in the unsupervised portion.
The Certificate Describes What Was Sampled, Not What Was Loaded
The certificate describes the sample. The sample describes only the portion the surveyor was present to sample. If the surveyor misses part of loading — scheduling conflicts, scope limitations, or loading running longer than expected — the certificate covers a subset of the cargo.
The scope of work determines what the surveyor does. If the scope specifies continuous attendance, the surveyor should be present for the entire operation. If the scope says sampling during loading without specifying continuous attendance, the surveyor may attend partially and issue a certificate based on the partial sample. The surveyor has fulfilled their scope. The trader assumed full coverage. The scope did not specify it.
The cost of adding continuous loading supervision to the scope is typically $800 to $1,500 per day. On a 3-day operation: $2,400 to $4,500 incremental cost. On a $3.5 million cargo: less than 0.15% of cargo value.
The ash penalty — 1.2% above maximum — triggered $3.50 per MT on 35,000 MT: $122,500. The trader filed a claim against the surveyor. The surveyor's liability was limited to 10 times the fee: $145,000. The claim was within the cap, but the surveyor contested liability on the ground that the scope did not specify continuous attendance.
Settlement: approximately $70,000 — the surveyor paid 57% of the penalty. The trader absorbed $52,500 plus $15,000 in legal costs. Unrecovered loss: approximately $67,500.
The operational lesson: the scope must specify continuous attendance during the entire loading operation and state that sampling must represent the entire loading period. If the surveyor cannot attend continuously, the trader must be informed in advance.
The certificate said 35,000 MT. The sample represented 23,000 MT. The difference was 12,000 MT loaded without supervision — and it was the difference between a clean certificate and a six-figure penalty. The scope was four pages. The words continuous loading supervision were not among them.
