Overview
Marine cargo surveying is the independent examination and documentation of cargo, cargo spaces, transport units or cargo operations. The exact scope depends on the instruction: condition, quantity, damage, loading, discharge, stowage, securing, sampling or another defined question.
For maritime professionals, the useful question is not only “what does the term mean?” but “what evidence would show that the work was performed properly?” This guide therefore focuses on the practical link between the governing framework, onboard or cargo-side activity, and the records a competent professional would expect to see.
Key Points to Understand

Practical Process
The exact method must always be adapted to the vessel, cargo, company procedures, local rules and the scope of the assignment. A disciplined sequence helps keep evidence complete and prevents the work from drifting away from its objective.
- Confirm the instructing party, purpose, location and limits of the survey.
- Review available cargo documents and identify the standards or contractual references relevant to the assignment.
- Attend the cargo, vessel or transport unit and record objective observations before drawing conclusions.
- Preserve a clear evidence trail and distinguish observed facts from opinion.
- Issue a structured report that answers the original instruction.
Common Mistakes
Most weak inspections, surveys and audits do not fail because the professional forgot a complicated formula. They fail because scope, evidence or follow-up became unclear. Watch especially for:
- Treating every cargo survey as the same job.
- Reporting conclusions without showing the supporting evidence.
- Failing to record limitations, inaccessible areas or missing documents.

- Scope agreed in writing
- Cargo and location positively identified
- Photographs and measurements referenced

Is a cargo survey the same as a statutory ship survey?
No. Cargo surveys are usually commercial or operational assignments focused on cargo, quantity, condition, damage or handling. Statutory ship surveys concern regulatory certification of the ship.
Who can request a cargo survey?
Depending on the transaction, instructions may come from cargo owners, insurers, carriers, charterers, agents, traders or other parties with an interest in the cargo.
Does a cargo surveyor decide legal liability?
A surveyor should document facts and, where instructed and competent, provide technical opinion. Final legal liability is a separate question for the relevant parties and their advisers.
