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.
