Appointing an independent inspector is routine on international steel cargoes, particularly where the buyer will never see the material before it is loaded. It is also widely misunderstood. An inspection certificate is not a warranty that the steel is good, and it does not replace the mill test certificate.
What an inspector provides is an independent pair of eyes at a specific moment, checking specific things that were agreed in advance. Knowing where that line falls is what makes the money worth spending.
Why Appoint One
The best known agencies in this field are SGS, Bureau Veritas, Intertek and Cotecna, though many smaller specialists operate in particular markets. What they sell is broadly the same service, and the scope you agree with them matters far more than which name is on the certificate.
- You are buying from a mill you have not dealt with before, or in a market where you have no presence.
- A letter of credit requires an inspection certificate as one of its documents.
- The end client or the project specification requires independent verification.
- The cargo is large enough that the cost of the inspection is trivial against the cost of a problem discovered on site.
The Stages of Inspection
Inspection is not a single event. Which stages you buy changes both the cost and the value.
- Pre-production — confirming the mill has the order specification correct before rolling starts. Rare, but useful on unusual grades or sizes.
- During production — attending the mill while material is rolled, and where specified witnessing mechanical testing. This is what a 3.2 certificate under EN 10204 requires.
- Pre-shipment inspection — the most common. The material is finished and ready, and the inspector checks it against the order before it leaves.
- Loading supervision — attending the load port, confirming what physically goes on board, checking stowage and lashing, and on bulk cargoes performing or witnessing a draft survey to establish weight.
What a Pre-Shipment Inspection Actually Covers
- Quantity and weight — counting bundles, coils or pieces, and verifying weights against the packing list, usually by weighing a sample and reconciling.
- Dimensions — measuring a sample against the ordered sizes and the tolerances of the governing standard.
- Marking and tagging — confirming that heat or cast numbers, sizes and grades on the tags match the documents. This is what makes the mill certificate traceable to the physical material.
- Visual and surface condition — looking for rust beyond what is acceptable, mechanical damage, coating defects, edge damage on coil, bent or distorted sections.
- Packing — whether banding, protection and packaging are fit for the voyage and the discharge method.
- Document review — checking that the mill test certificates exist, cover the material presented, and correspond to the order.
- Sampling — where specified, drawing samples for independent laboratory testing.
What It Does Not Cover
This is the part worth being clear about, because the gap between what buyers assume and what is actually contracted is where disputes start.
- It is sampling, not a full check. An inspector measures a representative sample. On several thousand tonnes, nobody measures every bar.
- It does not guarantee performance in service. The inspector confirms the material matched the specification at the point of inspection. How it behaves once fabricated and loaded is a different question.
- It does not replace the mill certificate. The certificate records what was tested and by whom. The inspection confirms the material in front of the inspector is the material the certificate describes.
- It only checks what the scope says. If chemical verification was not in the scope, it was not done. The scope of work is the document that matters, and it is agreed before the inspector attends.
- It does not cover what happens afterwards. Damage in transit, in storage or in discharge falls outside a pre-shipment inspection entirely.
Practical Points
A few things are worth settling before an inspector is appointed rather than after.
- Agree the scope in writing, and be specific about sample sizes, which tolerances apply and which standard governs.
- Decide who appoints and who pays. An inspector appointed and paid by the seller is still independent, but a buyer who wants control over the scope usually appoints directly.
- Build in time. Inspection has to be scheduled around the mill and the vessel. Discovering you need an inspector three days before loading rarely ends well.
- Check the certificate against the letter of credit wording if it is an LC document. An inspection certificate that does not say what the credit requires it to say is a discrepancy, and the fact that the inspection was done properly will not help.
The Short Version
A third-party inspection is a controlled check, at an agreed moment, against an agreed scope. It is good value on unfamiliar suppliers, large cargoes and anything with an LC attached. It is not a substitute for buying from a mill you trust, and it is not a warranty.
