For CNC purchase orders in Vietnam, align the order with the accepted quotation, controlled technical files, inspection requirements, payment milestones, confidentiality terms and tooling arrangements. Identify the legal parties and the people authorized to approve changes. A clear purchase order connects the commercial commitment to the exact component being purchased.
This guide is a practical decision checklist for international buyers, not a ready-to-sign contract or advice that any clause is enforceable in every jurisdiction. Have the responsible commercial and legal advisers review the governing law, dispute arrangements and contract wording for your transaction.
Verify the contracting entity and payment beneficiary
Match the supplier’s registered name, address and identifying details across qualification records, quotation, contract and invoice. Understand any difference between the trading name, factory operator and exporter. A business registration establishes identity information; it does not prove machining capability or export experience.
Confirm the beneficiary and approved payment instructions through established contacts. If bank details change, independently verify the request using a known channel before paying. Resolve a third-party beneficiary or inconsistent legal name rather than treating it as a clerical detail. Use the Vietnam supplier qualification guide for the wider verification process.
Specify the order baseline and document precedence
Reference the quotation and its revision, part numbers, drawings, models, material specifications, finish, quantities and applicable quality requirements. List approved exceptions explicitly. Agree how conflicts among the PO, contract, quotation and technical documents will be resolved; do not assume an attachment overrides all other terms merely because it was emailed later.
Keep engineering queries closed against a recorded decision. If a supplier quote excludes an inspection report that the PO requests, resolve the scope and price before production. The RFQ checklist provides a structured starting package; the PO should reflect the final agreed version rather than an early enquiry.
| PO readiness check | Decision to record | Evidence or reference |
|---|---|---|
| Part and quantity | What is ordered now, and what is forecast only? | Part list, release quantity and approved revision. |
| Technical requirements | Which material, finish and exceptions apply? | Controlled files and signed-off query/deviation references. |
| Price and currency | What is included, excluded or separately charged? | Accepted quote, currency, validity and charge breakdown. |
| Quality acceptance | Which records and approvals are required? | Inspection plan, submission list and release authority. |
| Payment | What event makes each amount due? | Agreed milestones, evidence and review timing. |
| Delivery | What handover point and date are committed? | Incoterms rule, named location, edition and milestone. |
| Change and claims | Who can authorize changes and handle problems? | Named contacts, procedure and agreed remedies. |
Connect payment milestones to observable events
There is no deposit percentage established by this guide for all Vietnamese CNC suppliers. Negotiate the structure for the project, including currency, bank charges, taxes where relevant, due dates and required supporting documents. Separate tooling or setup commitments from recurring component payments when the commercial scope calls for it.
Examples of milestone definitions include order acceptance, completion of a specified tooling stage, submission of an agreed sample package, approval of a defined batch or presentation of shipment documents. These are possible events, not TDB payment terms. State what evidence completes the event and how a disputed or incomplete submission is handled.
Avoid circular conditions. If production waits for payment and payment waits for production approval, define the intermediate deliverable. Also identify what happens when buyer approval is late: whether the schedule moves, material remains reserved or storage costs need discussion. Agree this before the first delay.
Use an NDA with practical information controls
Decide what confidential information will be shared, for what purpose and with whom. Address access by employees, approved subcontractors and professional advisers, as appropriate. Establish the permitted use, disclosure controls, retention or return process and treatment of information already public or independently known, using legally reviewed wording.
WIPO’s trade-secret guidance identifies reasonable confidentiality measures, including agreements, as part of protecting secret business information. An NDA should therefore be supported by practical file access, identification and communication controls. A signed document alone does not describe who can open a drawing or send it to an external processor.
Share the technical detail necessary for an accurate review through the agreed channel. For sensitive projects, agree the confidentiality arrangement before transferring restricted files. Do not publish customer drawings, names or project images as marketing examples without the required permission.
Define tooling ownership separately from other rights
A fixture charge does not by itself define ownership of fixtures, cutting tools, CAD files, CAM programs, supplier know-how or manufacturing records. List the assets and deliverables separately. Distinguish pre-existing supplier resources from customer-funded dedicated items and agree the rights relevant to each.
| Tooling register field | Question to settle |
|---|---|
| Identity and scope | Which fixture, gauge or dedicated item is included? |
| Ownership and use | Who owns it, and may it be used for other work? |
| Custody and identification | Where is it held and how is it identified? |
| Maintenance and replacement | Who pays for routine service, wear, damage or redesign? |
| Storage and inactivity | How long is it retained and under what conditions? |
| Transfer or end of program | What may be returned, when, at whose cost and with which records? |
Where software or technical data must be transferred, name the files, format, license or ownership rights and support scope. Do not assume a component purchase includes the supplier’s complete machining program. Resolve these matters expressly with the responsible advisers.
Control changes, cancellation and nonconforming parts
Identify who may authorize technical and commercial changes. Define how the supplier reports the effect on cost, material already purchased, work in progress, tooling and delivery. A drawing revision should have an effective order or lot; old and new requirements should not coexist without a disposition plan.
Agree what happens if an order is cancelled or reduced after material procurement or machining begins. Identify treatment of dedicated stock and partly completed items. Use the production approval roadmap to separate sample approval from the authorization for a larger batch.
For defects or delivery problems, agree notification, evidence, containment, inspection or return arrangements and remedies. Distinguish rework from an authorized concession, and identify the approval authority. Define claim timing and responsibility in the contract rather than relying on an article or an informal expectation.
Keep transport risk, payment and title separate
Write the agreed Incoterms rule with a precise named location and edition. The US International Trade Administration explains that Incoterms allocate transport-related tasks, costs and risks, while payment timing and transfer of ownership require separate agreement. They are not a complete sales contract.
For example, “FCA [agreed handover location], Incoterms 2020” still requires the actual location and supporting arrangements to be settled; the example is not a shipping commitment. Review the US, Germany and Canada shipment guide with the responsible logistics team.
CNC purchase orders: complete the readiness review
Have engineering confirm the released files, quality confirm the acceptance plan, purchasing confirm the commercial scope and logistics confirm the handover. Record unresolved items with an owner and deadline. Use the CNC cost and hourly-rate guide to distinguish setup, recurring production, documentation and shipping charges when checking quote completeness.
For a first order, a short, consistent package is more usable than conflicting instructions across many messages. Keep an accessible record of the accepted PO, supplier acknowledgement and approved changes so later repeat releases reference the same baseline.
Frequently asked questions
What deposit is normal for every Vietnam CNC order?
This guide sets no standard percentage. Negotiate payment milestones, evidence, currency and due dates for the supplier and project.
Does paying for a fixture give me the CNC program?
Do not assume that. Define ownership and transfer rights separately for physical tooling, programs, drawings and other deliverables.
Does an NDA allow unrestricted subcontracting?
Specify permitted recipients and any approval or confidentiality obligations in the reviewed agreement. Do not infer permission from silence.
Do Incoterms determine when I own the goods?
No. Agree title transfer and payment terms separately from the chosen transport rule.
Can this checklist be used as a legal contract?
It identifies decisions to make. It does not replace transaction-specific drafting and legal review.
