your project specification, quality manual, inspection and test plan could help you to know what to do...this will definetely help you to gain knowledge of the project requirements

Someone has bought those materials. To buy the material, someone has placed a purchase order. The purchase order states (or at least should have stated) the kind of material that was covered and the certificates that were to be handed by the vendor to the purchaser.

Then, when the vendor delivered the material, someone checked that the material actually delivered was exactly what the purchase order stated, and that the required certificates were included. Without this checking no payment to the vendor is authorized.

So, as you see, it's not that difficult to gather the information you need.

The major issue is "no marking or without marking". What can you advise Prof if you are 1) the customer? 2) the contractor?

The main document I'd require to see is the purchase order. It describes what the purchaser has paid for and the vendor is committed to supply.
The second document is the vendor's proposal. This doesn't replace the purchase order but may clear up some points that in the purchase order aren't sufficiently clear.
The third document is the material acceptance signed by the purchaser representative.
These three documents should be sufficient to clear out all of the doubts.
If not, I'd say Tim Gary has given the only feasible solution.

Now, if I were doyen, before putting it in action, I'd try to convince my customer to accept the product analysis in lieu of the ladle analysis, complemented by the tensile strength of the material (A 36, as doyen says). Any qualified lab should be able to run both. If I were the customer I surely would accept this procedure.
I don't know how things are in UAE nor in the States. I know how they are in Brazil.

If you can't provide competant material traceability with the materials you have, then you need to get new materials.
Make sure the vendor knows when you order them that MTR's and Heat numbers are required.
When you unload and inspect the material, transfer the heat number to each piece.
When you cut parts, transfer the heat number to each part, especially drops that are left over so you can maintain traceability.
You need to see exactly what the contract says about traceability.
Some customers require traceability maps as well, which record the heat number and MTR for each part with location identified on a drawing.
