This is what a buyer checks before they shortlist a metals and metalworking supplier.
What does a buyer check before placing a steel order with a new supplier?
They check the grade against a named standard, whether you can issue a mill test certificate traceable to a heat number, and whether you are the mill or a stockist. Those three facts decide whether your quote can be compared with the others on the buyer's desk.
A project buyer is comparing three quotes and needs to know which of them can actually supply against the specified standard.

What does a buyer check before placing a steel order with a new supplier?
What a buyer needs to identify the product
These are the fields a buyer scans before deciding whether you are worth contacting. Missing one of them usually ends the visit without an email.
- 1
Grade and standard
IS 2062 E250, IS 1786 Fe 500D, ASTM A36 — the grade only means something beside its standard.
- 2
Section, size and thickness range
Tells the buyer immediately whether their bill of materials is inside your range.
- 3
Dimensional tolerance standard
Fabricators plan around the tolerance, not the nominal size.
- 4
Heat or cast number traceability
The link between the physical steel and its certificate.
- 5
Coating or finish
Galvanised, painted and bare change both price and application.
- 6
Length, packing and loading unit
Determines transport cost and site handling.
- 7
Mill or stockist
Changes what the buyer can expect on lead time, certification and minimum quantity.
The documents buyers ask for
Not all of them belong on a public page. Naming the ones you can issue is what separates a supplier who can be audited from one who cannot.
| Document | What it proves | Where it belongs |
|---|---|---|
| Mill Test Certificate to EN 10204 3.1 or 3.2Asked at: with every consignment; often a purchase order condition | Chemical composition and mechanical properties, tied to a heat number | Per shipment |
| BIS licence and IS grade markingAsked at: indian projects and government tenders | Licensed conformity to the Indian standard for the product | Publish it |
| Third-party inspection acceptanceAsked at: export and large project orders | Willingness to be inspected by SGS, Bureau Veritas, TÜV or the buyer's nominee | Publish it |
| ISO 9001 certificateAsked at: vendor registration | Quality system with number and certification body | Publish it |
| Factory production control certificate (EN 1090)Asked at: by eu buyers of structural product | Structural steel conformity for the European market | Publish it |
| Embedded emissions dataAsked at: increasingly, by european buyers | Carbon accounting per tonne, which EU importers now need from their supply chain | Name it, share on request |
| Sample mill certificateAsked at: before a first order from a new supplier | What your paperwork actually looks like | Publish it |
Where steel and tmt sites lose the enquiry
Each of these is common, cheap to fix, and costs an enquiry that never arrives — so nobody ever reports it.
"Export quality" with no standard named
It is the phrase buyers most associate with a supplier who cannot meet a named standard.
No sample mill certificate anywhere on the site
A redacted sample certificate answers more questions than any amount of copy about quality.
Stockists presenting themselves as mills
The buyer discovers it at the certificate stage and the relationship starts with a correction.
What the enquiry form should ask
A form that collects these can be answered properly the first time. A form that collects a name and a message cannot.
Enquiry form — steel and tmt
Enough to reply usefully, short enough that a buyer finishes it.
- Grade and standard
- No quote is possible without it.
- Section, size and quantity in tonnes
- Drives price, rolling schedule and freight.
- Certificate type required
- 3.1 and 3.2 are different costs.
- Third-party inspection requirement
- Affects lead time and needs planning.
- Destination port or site
- Freight is a material part of the landed price.
- Delivery schedule
- One shipment or a call-off over a quarter changes the whole quote.
Questions suppliers ask
Should a stockist say so on the homepage?
Yes, and it is an advantage rather than an admission. Buyers with urgent or mixed-grade requirements are specifically looking for stock, and they cannot find you when your site is written to imitate a mill. State the role and let each buyer self-select.
Is publishing a redacted mill certificate risky?
Not if you remove the customer, the price and the order reference. What remains — the format, the standard, the heat number field, the signatures — is exactly what a new buyer is trying to establish, and no paragraph of prose substitutes for it.
How much should we say about capacity?
State the rolled sections and sizes you actually produce, and the practical monthly tonnage in each. Buyers use capacity to judge whether their order will be prioritised or squeezed, so a specific figure is more reassuring than a large vague one.
Documents and standards named here are the ones buyers in this industry commonly ask for; requirements vary by market, customer and contract, so treat this as a starting checklist rather than a compliance list. Clearer pages can help discovery and evaluation. They do not guarantee rankings, AI citations, enquiries or revenue.
