Equivalent steel grades across EN, ASTM, JIS, GB and GOST, the standards each steel product is made to, what an EN 10204 mill certificate says, and where to find the standards bodies of the GCC, the Middle East and the world.
Approximate equivalents for guidance only — chemical and mechanical properties differ between standards; always check the standard and the mill certificate.

| Type | Document | What it says |
|---|---|---|
| 2.1 | Declaration of compliance with the order | No test results. |
| 2.2 | Test report | Results from non-specific inspection — the mill's usual production tests, not tests on this delivery. |
| 3.1 | Inspection certificate 3.1 | Specific inspection of the delivered product, validated by the mill's inspector who is independent of production. |
| 3.2 | Inspection certificate 3.2 | As 3.1, and also validated by the purchaser's inspector or a third party named in the order. |
Buyers usually ask for a 3.1 certificate for most projects, and 3.2 for oil & gas and other critical work.
