Technical Clarification Log for RFQs
A clarification log records each question, supplier response, assumption, owner, date and whether it changes the technical or commercial baseline. It prevents important email answers from disappearing during comparison.
Practical buyer guide | Updated August 27, 2026 | Final scope must be verified through drawings, samples and agreed acceptance tests
Direct answer
What this decision means for a real filling project
A clarification log records each question, supplier response, assumption, owner, date and whether it changes the technical or commercial baseline. It prevents important email answers from disappearing during comparison.
This guide is part of the cluster. Read the hub when the project still needs a broader comparison.
Engineering inputs
Define the duty before comparing equipment
A useful proposal starts from agreed process and package information. These inputs keep suppliers from filling gaps with incompatible assumptions.
Send these details
- Common RFQ and quotations
- Open technical questions
- Responsible contacts
- Response deadline
- Baseline document list
Require these checks
- Number every question
- Require written responses
- Mark resolved deviations
- Transfer final answers into the contract documents
Line integration
Connect the choice to upstream and downstream equipment
Project decision record
Turn the topic into four controlled project decisions
A useful guide should change the RFQ, proposal and acceptance plan. Use this record to keep the buyer, equipment supplier and site team on the same basis.
Freeze the application basis
Record common RFQ and quotations together with open technical questions. Attach drawings, photos and representative samples when dimensions or product behavior affect the design.
Define rated and sustained duty
State responsible contacts and response deadline. Separate nameplate rate from the sustained result expected with normal stops, changeovers and quality checks.
Control line interfaces
Mark every interface as supplier scope, buyer scope or third-party scope before the order is released.
Approve measurable evidence
Agree how to verify number every question and require written responses. The test plan should identify samples, duration, instruments, pass criteria and closure evidence.
Comparison sheet
Put every supplier on the same basis
| Decision area | What to state in the RFQ | What to verify |
|---|---|---|
| Product | common RFQ and quotations | number every question |
| Package | open technical questions | require written responses |
| Performance | responsible contacts | mark resolved deviations |
| Operation | response deadline | transfer final answers into the contract documents |
| Project scope | Utilities, interfaces, documents, spares, packing, shipping and support | Written inclusions, exclusions and acceptance evidence |
Verification route
Move from a claim to recorded evidence
- Approve the duty, drawings and test conditions before fabrication is treated as final.
- Use production-intent product and packaging wherever they materially affect performance.
- Record results by format, operating condition and quality criterion rather than relying on a short edited video.
- List open items, owners and closure evidence before packing and again after site commissioning.
Risk register
Resolve these risks before price becomes the deciding factor
Low quotations often hide different assumptions. A short written risk register makes technical and commercial differences visible before contract award.
| Risk | Why it matters here | Required control |
|---|---|---|
| Application mismatch | An unanswered item should not be treated as included merely because it appears obvious to one party. | Confirm common RFQ and quotations and test number every question. |
| Package or format mismatch | Unapproved containers, closures, labels or tolerances can invalidate an otherwise suitable machine choice. | Freeze open technical questions and verify require written responses with production-intent samples. |
| Line imbalance | A filler cannot deliver saleable output when feeding, closing, labeling, packing or utilities become the constraint. | State responsible contacts and verify mark resolved deviations across the connected line. |
| Weak acceptance evidence | Put transfer final answers into the contract documents into the FAT and SAT plan, including owners and close-out evidence. |
Buyer questions
Answers to common RFQ and acceptance questions
When is Technical Clarification Log for RFQs useful?
Buyers evaluating several filling-line quotations or negotiating final scope. An unanswered item should not be treated as included merely because it appears obvious to one party.
What details should be supplied before requesting a quotation?
Prepare the following project-specific information: common RFQ and quotations, open technical questions, responsible contacts, response deadline, baseline document list. Drawings, photos and representative samples help the engineering review move from a budget assumption to a defined scope.
How should the proposed solution be checked before acceptance?
Use an agreed review or test plan to number every question, require written responses, mark resolved deviations, transfer final answers into the contract documents. Record the conditions, measurements and open actions so the result can be compared with the approved specification.
What should the supplier proposal state for machinery RFQ clarification log?
The proposal should state the design basis, included equipment, utilities, interfaces, output conditions, change parts, documentation, spare parts, delivery boundary and acceptance method. For this topic, explicitly record common RFQ and quotations and open technical questions.
What evidence should be retained after FAT and site handover?
Retain the approved specification, drawings, test conditions, measured results, alarm and safety checks, open-item register, manuals, backups, parts list and signed handover record. This guide particularly requires evidence for number every question and require written responses.
