Important Questions to Ask a Contract Manufacturing Partner
Questions that clarify scope, responsibility, documentation, and qualification before a contract manufacturing conversation turns into an order.
Ask questions a written answer can survive
Contract manufacturing covers a wide range of arrangements. The useful questions force the parties to name who does the work, who owns the specification, and which documents come back with the parts. A confident brochure is not one of those documents.
Ironvale may discuss contract production directly or with a production partner. Nothing on this page means a partner has been selected or approved for your part.
Scope and responsibility
These questions should be answered in writing before a purchase order.
- Will you manufacture this part, or will a named partner manufacture it?
- Who is the engineer of record for the design? If it remains the buyer, say so.
- Which revision will the quotation follow, and how are later revisions priced?
- Which processes are included, and which are outside the quote?
- What happens if the drawing is incomplete?
- Is a first article or sample part included, and who approves it?
Documentation and quality
Ask what records the route can actually provide. Do not ask a partner to invent a certificate. If you need a quality management certificate such as ISO 9001, ask whether that organization holds a current certificate and for which scope. Ironvale does not claim one.
If a code or standard applies, cite it yourself, including the edition. A partner should confirm whether they will work to that citation, not choose a code because it is familiar.
Commercial and continuity questions
Quantity, release schedule, tooling ownership, and what happens if a partner changes all belong in the agreement. A website form cannot settle them. Use the questions to prepare the agreement, then keep the answers with the quotation.
- What is the minimum quantity, if one has been established for this part?
- Who owns tooling or fixtures, if any are required?
- How are nonconforming parts handled?
- What notice applies if the production route changes?
- Which documents will you not provide?
Checklist
- Maker named, including any partner
- Design responsibility unchanged unless the contract changes it
- Revision and change process stated
- Included and excluded processes listed
- Documents the route can provide listed without invented certificates
- Tooling ownership and minimum quantity stated only if actually established
- Qualification status described as incomplete until your process says otherwise
