A practical guide to the eight information groups your maintenance team must gather before sending an RFQ for industrial spare parts — and what happens when they are missing.
B2B PROCUREMENT & SUPPLY CHAIN / 24A request for quotation (RFQ) is only as good as the information behind it. When a maintenance team sends an RFQ with vague wording like "one pump seal for the big pump," the buyer, the supplier, and ultimately the plant all lose. The supplier has to guess, the quote comes back wrong, and the order arrives late — or worse, with the wrong part.
The fix is simple: gather the right technical and commercial information before you press send. This article walks through the eight groups of information your maintenance team should collect and share whenever an RFQ goes out.
A well-prepared RFQ does three things:
Every missing field adds cost downstream. The table below shows what commonly goes wrong when key details are left out.
| Missing information | Typical consequence |
|---|---|
| Part number | Supplier cross-references to the wrong item |
| Operating conditions | Material chosen fails under heat/corrosion |
| Tolerance/spec | Part made to wrong dimensions |
| Quantity & timeline | Wrong pricing tiers, delayed delivery |
| Certifications | Part rejected during inspection |
| Maintenance history | Root cause repeats after replacement |
Never describe a part in isolation. Give context about the equipment it belongs to:
This helps the supplier confirm they are quoting for the correct application, especially on older or heavily modified installations.
This is the heart of the RFQ. Include as many of these as possible:

Do not rely on names alone. Share the physical and performance data that defines the part:
Parts are chosen as much for where they run as for what they do. Specify:
Commercial clarity prevents pricing surprises:
If compliance matters, say so up front:
A supplier can quote a better solution when it understands the problem:
Close the loop:
Use this as a starting skeleton for your own RFQ template:
Machine / equipment:
- Type, model, serial
Part identification:
- Part number, brand, description
Specifications:
- Material, dimensions, tolerances
- Operating conditions
Commercial:
- Quantity, delivery date, location
Compliance:
- Certificates, standards, documentation
Context:
- Failure mode, maintenance history
Contact:
- Owner, site, preferred format
Once the technical data is complete, decide what you are buying — original equipment, surplus, refurbished, or used. Each option has different lead time, cost, and warranty implications. Our guide to OEM vs. aftermarket vs. refurbished vs. used parts breaks down the trade-offs.
And if the part is no longer in production, follow the obsolete and discontinued parts sourcing checklist to avoid dead-end sourcing.
The RFQ is a two-way communication document, not a purchase order. When a maintenance team shares complete machine data, part identification, operating conditions, commercial terms, compliance needs, and history, suppliers can quote accurately the first time. That accuracy directly translates into shorter lead times, fewer returns, and less downtime — which is exactly what every maintenance team is trying to protect.
