How to Write a Laboratory Testing RFQ
A clear RFQ gets you comparable, accurate quotations. A vague one gets you questions, delays and prices padded for uncertainty.
The essentials every RFQ needs
- The test, standard or method — with edition/year if specified (e.g. ASTM D638-22)
- The material or product, including grade, formulation or part description
- Number of samples and specimens per sample
- The purpose: qualification, lot release, failure investigation, R&D
- Required turnaround and any hard deadline
- Reporting requirements: certificate of analysis, full report, accredited report
Details that prevent re-quotes
- Sample condition and any preparation you will do vs. expect the laboratory to do
- Whether witnessing, retained samples or raw data are required
- Confidentiality constraints and whether the work supports litigation or regulatory submission
- Shipping constraints: hazardous, temperature-controlled, fragile
What to leave out
Avoid asking for 'full testing' or 'everything relevant' — laboratories can only price defined work. If you do not know the method, say so and describe the problem instead; a good laboratory will propose the approach.
Common questions
- How many laboratories should I send the RFQ to?
- Two to four is typical. Enough to compare, few enough that each gets a serious, complete request.
- Should I include a target price?
- Optional. A budget range can help laboratories propose the right level of work, but an unrealistically low target may get no responses.
