UDI Laser Marking RFQ Checklist: Parts, Codes, Vision and Data Interfaces
Turn a marking-machine price request into a comparable equipment quotation. Define what the customer supplies, what the station creates and how the two systems exchange decisions.

A useful UDI laser-marking RFQ defines the complete manufacturing station, not only the laser source. Give each supplier the same part families, permitted mark locations, approved code examples, production assumptions and interface responsibilities. Require a line-by-line response that separates included functions, options, customer work and unresolved items.
This checklist is for equipment procurement and integration planning. The medical UDI marking and traceability guide explains the wider process route, while the marking acceptance evidence checklist addresses how a proposed configuration can later be tested.
1. Define the part family before choosing the station
Provide controlled drawings and representative photographs with material, finish, curvature and allowed marking zones. Identify the smallest and largest intended parts, loading orientation, prohibited contact areas and neighboring features that require protection. Group genuinely different handling or optical tasks instead of presenting the range as one nominal part.
State whether the station receives loose components, assembled devices, trays or an upstream automated carrier. Include changeover expectations and how the operator or host system selects the correct part recipe. Explain which samples are available for evaluation and which are substitutes, so trial work can be quoted realistically.
2. Issue a controlled code and data specification
Supply approved synthetic examples for each required code format and variable-data pattern. Identify the data owner and the rule for authorizing a change. Keep production identifiers and personal information out of exploratory sample files unless their use is specifically required and properly controlled.
Define the exact source of each field: a host message, work-order import, operator entry or station-generated value. List required checks and which system is responsible for them. Include what the station may do when input is absent or invalid; it should not silently invent a substitute identifier.
FDA's UDI Basics describes labeler responsibilities beyond physical marking. The responsible organization should approve the required identifier scheme and applicable content; an equipment quotation should describe how that approved task is implemented.
3. Ask for a responsibility and price matrix
| Scope line | Input or decision required | Supplier response |
|---|---|---|
| Laser and optics | Part materials, finishes and mark-area requirements | Proposed route, trial basis and supplied configuration |
| Fixtures and loading | Part range, datums and changeover concept | Included tooling, options and customer interfaces |
| Vision and reading | Placement, orientation and reading tasks | Function, hardware and test assumptions |
| Quality verification | Required method, report and sampling scope | Included or optional instrument and integration |
| Host communication | Message contract and system owner | Protocol, development boundary and test environment |
| Records and exports | Required fields and retrieval use | Storage boundary, export format and delivery scope |
| Site and handover | Utilities, training and acceptance plan | Customer work, deliverables and exclusions |
Give unresolved rows an owner and due point. A low quotation with undefined tooling or integration is not directly comparable with a complete station proposal.
4. Describe the data handoff as a sequence
Draw the intended cycle from work-order receipt through recipe selection, part confirmation, marking, inspection, record submission and part release. For each handoff, define the initiating system, response, acknowledgement and relevant timeout behavior. State what constitutes completion rather than relying on a generic “ready” signal.
Assign responsibility for communication loss, an interrupted cycle and a repeated request. Decide how a recovered transaction refers to the same physical part and whether another mark is permitted. Include who provides the host simulator, test messages, credentials and integration access; arrange sensitive access through the customer's normal IT process.
Ask whether interface development, customer-specific field mapping, on-site integration and later changes are included. These commercial boundaries should be visible before an order, not discovered during installation.
5. Separate vision roles and production assumptions
List locating, presence checks, text inspection, code reading, expected-data comparison and quality verification as distinct functions where needed. Request the proposed device and output for each. A single image in a demonstration does not establish that every inspection role has been supplied.
GS1's verification process guidance provides background on a consistent quality and encoded-data service. Use the agreed project requirements to define the actual deliverables rather than writing only “UDI camera included.”
State the production target together with product mix, loading, inspection, record transfer and changeover assumptions. Ask suppliers to separate processing time from the complete handling cycle and identify any proposed manual operations. Treat untested timing as an assumption requiring confirmation.
6. Define what comes back with the quotation
- A document list and revision-controlled response to every scope line.
- A configuration description covering source, optics, motion, fixtures and inspection.
- A data-interface proposal with customer and supplier responsibilities.
- A trial plan, sample requirements and the evidence included in its price.
- A delivery list for programs, backups, reports, training and agreed support.
- An explicit list of options, exclusions, assumptions and open decisions.
Use the medical UDI laser-marking and vision-traceability system as the equipment entry for a defined project. Attach this RFQ packet when you request a configuration and quotation. For other operations around the marked component, return to the medical-device manufacturing hub.
