Grade and designation
State UNS, ASTM type, EN number/name, JIS SUS or GB designation and permitted alternatives.

Stainless Steel RFQ Checklist
A complete RFQ lets suppliers quote the same technical and commercial scope. The checklist should remove uncertainty about material, dimensions, processing, inspection, documentation and delivery.
Material identityGrade plus standard
Quality evidenceTests and documents
Commercial basisQuantity, Incoterm and destination
Decision summary
Define the product before asking for a price
Price comparisons are unreliable when suppliers have interpreted missing requirements differently.
Product standard
Name the specification and edition for sheet, plate, coil, bar, pipe, tube or fitting.
Dimensions and tolerance
Add thickness/wall, width/OD, length, schedule, edge, straightness, flatness and special limits.
Condition and finish
Define annealed, cold-worked or heat-treated condition plus finish, roughness and protective film.
Processing and inspection
List cutting, forming, welding, machining, NDE, PMI, testing and acceptance.
Commercial delivery
State quantity, unit, packaging, Incoterm, named place, delivery window and destination restrictions.
Reference table
Stainless steel RFQ field checklist
Complete every applicable row or mark it not applicable. Do not leave safety- or quality-critical fields to supplier assumption.
| RFQ block | Required fields | Useful attachments | Risk if omitted |
|---|---|---|---|
| Material | Grade, product standard, edition, permitted substitution | Specification or material-selection note | Wrong alloy or incompatible standard |
| Form and dimensions | Form, nominal size, tolerances, edge/ends, length | Drawing, cut list or size schedule | Non-comparable weights and processing |
| Condition and surface | Heat treatment, temper, finish, roughness, film | Finish sample or roughness map | Appearance or fabrication mismatch |
| Processing | Cut, bend, weld, machine, passivate, mark | CAD, weld map, procedure requirements | Hidden scope and later change cost |
| Inspection and documents | MTC type, PMI, NDE, tests, inspection hold points | ITP, certificate example, code clauses | Unverifiable compliance |
| Quantity and logistics | Quantity/unit, packaging, Incoterm, place, date | Packing instruction and delivery schedule | Price and freight ambiguity |
| Supplier response | Deviations, lead time, validity, origin, mass basis | Completed compliance matrix | Silent exceptions |
A supplier should identify every exception and assumption in the quotation. Commercial terms should use the named Incoterms rule and place, not only a three-letter abbreviation.
Working method
Issue and compare RFQs consistently
The same baseline should reach every bidder, and revisions should be controlled.
Freeze the requirement
Create one numbered specification, drawing set and revision date.
Issue a response matrix
Require comply, deviate or not applicable against each technical line.
Clarify in writing
Distribute material clarifications to all bidders where procurement rules require equal information.
Normalize the comparison
Compare material basis, processing, testing, documents, freight, exclusions and delivery before price.
Limits and escalation
Do not let the checklist replace engineering approval
Unknown service needs review
The buyer must define environment, load, temperature and code before a supplier can responsibly select material.
Alternatives need approval
Lower-cost substitutions require documented technical comparison.
Certificates must be specified early
Some inspection documents and tests cannot be recreated after manufacture.
Delivery terms allocate risk
Incoterms do not replace the sales contract, payment, title, warranty or import requirements.
Interactive planning aid
Check RFQ readiness
Select the current status of four core blocks. The score identifies what must be completed before issue.
Frequently asked questions
Stainless steel RFQ FAQ
At minimum state grade, product standard, form, dimensions, quantity, finish/condition, destination and required delivery basis.
Requirements and referenced methods can change between editions, and projects may freeze a specific one.
Yes. Inspection-document type and any specific tests should be agreed before production.
Require suppliers to identify alternatives as deviations and provide a documented technical comparison for buyer approval.
Method, sources and review
Traceable sources and review status
Official product-standard catalog for defining material and form.
Official inspection-document standard for steel and steel products.
Official source for Incoterms delivery rules and guidance.

The checklist organizes an inquiry but does not select a grade, perform code design or replace the purchase contract and licensed standards.
RFQ preparation context
Make the known requirements visible before the supplier prices the request.
A useful RFQ connects grade, form, dimensions, tolerance, finish, quantity, standards, documents, packaging and delivery terms into one reviewable requirement.
- Material identity
- Dimensional input
- Delivery terms
Visual process context
Show the material context and the acceptance detail together.
Reserve one image for the supplied form or drawing and another for inspection, packaging or documentation requirements.
