Cargo inspection explained: what independent surveyors do

Why independent inspection exists

In long-distance trade, the buyer cannot be at the loading port and the seller cannot be at discharge. An independent inspection company, often called a surveyor, acts as the eyes of both. Well-known international groups exist, along with many regional firms. What they sell is a neutral record that the parties agreed to rely on.

What an inspector can do

• Quantity: weighing on a weighbridge, a draft survey of a vessel, tank measurement for liquids, or counting packages and containers.
• Quality: drawing representative samples, preparing them and sending them to a laboratory, or witnessing tests.
• Condition: checking that goods, packing and containers are in good order, and noting damage or contamination.
• Supervision: attending loading or discharge, checking hold or tank cleanliness before loading, and sealing containers.
• Documentation: issuing certificates and reports with photographs.

Common certificates

• Certificate of weight or quantity.
• Certificate of quality or analysis, often based on a laboratory test.
• Certificate of condition or cleanliness of holds, tanks or containers.
• Loading or discharge supervision report.
• Photographic report of stuffing or sealing of containers.

Pre-shipment and discharge inspection

How sampling works

A sample is only as good as the way it is taken. For bulk goods the inspector takes many small increments across the loading stream or the pile, combines them and divides the result into several sealed parts: one for the laboratory, one for the seller, one for the buyer and one kept in reserve. Method standards describe how many increments are needed for each material. Sealed and signed samples are what make later disputes resolvable.

Ordering an inspection

• Choose a company that both sides accept, and ideally one with a local office at the port or site.
• Send written instructions: product, quantity, location, dates, services needed, standards to apply and who gets the reports.
• Agree who pays, and whether the cost is shared.
• Agree whether the result is binding, and how disagreements are handled.
• Confirm the appointment well before loading, and give the inspector access and contacts.

Reading an inspection report

Look at the dates, the place, the scope of the work and whether the inspector attended the entire loading or only a part. Compare weights with the bill of lading and the invoice. Check that photographs show container and seal numbers or the hold and the cargo. Note any remarks or reservations, because a short sentence on the report can matter a great deal in a claim.

Limits of an inspection

An inspection is a snapshot. It reports what the inspector saw and measured within the scope instructed. It does not guarantee anything outside that scope, such as the content of containers that were sealed before attendance. Define the scope clearly and ask for what you need, such as full-time supervision rather than a single visit.

Inspection in your first deals

For a first deal, a small trial lot checked by an independent inspector is a good way to learn how the other side works. Many members use the Deal Room claims channel and the verify tool to compare notes on documents. A clean inspection pays for itself the first time it prevents an argument.

Frequently asked questions

Who pays for the inspection?

It is agreed in the contract. Often the party that requires it pays, or the cost is shared. Settle this before appointment.

Is an inspector's result always final?

Only if the contract says so. Otherwise it is evidence that can be challenged. Contracts often name a binding laboratory or inspector.

What is a draft survey?

It is a method for weighing bulk cargo on a vessel by reading the draft marks before and after loading and calculating the weight from the vessel's displacement.

Can the buyer appoint the inspector at the seller's site?

Yes if the contract allows, and the seller gives access. Both sides should agree on the company and the scope.
