How to buy machined parts from Vietnam without running a supply chain
September 26, 2026
There are three ways to buy machined parts from Vietnam. They differ in how much of the work you keep, and choosing the wrong one is the most common reason a first order goes badly.
Route 1: quote shops directly
You find shops, request quotes, compare them, place a purchase order with a factory and manage the order yourself.
What it costs you: finding and qualifying shops, comparing quotes with different scopes, agreeing terms in a second language, arranging inspection, arranging freight, and resolving anything that goes wrong across a time zone.
When it works: you have a sourcing team, you are placing enough volume to justify their time, and ideally someone who can visit.
Route 2: a global platform
Upload, get an automated price, receive parts from whichever country has capacity.
What it costs you: less time, more distance. You usually do not know which country or which shop made your parts, and nobody is standing on the floor while they run.
When it works: prototypes and simple parts where speed matters more than control.
Route 3: a hub that owns the order
One supplier quotes, takes the order, places the machining with a shop it has audited, inspects the parts and ships them. You get one purchase order and one invoice.
What it costs you: a margin, in exchange for not carrying the coordination or the risk.
When it works: production parts where a bad batch is expensive, and teams that do not want a new vendor record for every shop. This is what we do, and the mechanics are on how it works.
The order of operations for a first order
Whichever route you pick, run it in this sequence. Most failures are a step taken out of order.
1. Decide whether the part suits the country. Labour-heavy, stocked material, shippable size, a few hundred pieces or more. The economics are in what machining in Vietnam costs.
2. Get the drawing package right. STEP plus PDF, revision named, general tolerance note, two or three critical features called out, finish specified with a standard. The RFQ template has the wording and the readiness check scores it.
3. Settle the commercial basics before the price discussion. Who invoices you, in what currency, on what payment terms, on what delivery basis, and what happens to a part that fails inspection. A supplier who cannot answer those in writing is a supplier you will be arguing with later.
4. Agree what a first article means. How many pieces, measured against what, reported how, and how long you have to approve it. Your approval time sits inside the lead time.
5. Protect the drawing before it travels. NDA if the design is genuinely sensitive, title block stripped of your customer’s name either way. More in protecting drawings when sourcing abroad.
6. Split the first production order if you can. Half now, half after inspection. Serious suppliers accept this more often than buyers expect.
The documents to expect
- Commercial invoice and packing list with every shipment
- Certificate of origin where you want preferential duty treatment
- Inspection report measured against your drawing, with actual values rather than ticks
- Material certificate where you asked for traceability, which is a decision to make before the material is bought rather than after
What usually goes wrong, and when
| Stage | Common failure | Prevention |
|---|---|---|
| Quoting | Quotes are not comparable | Fix the scope in your request |
| Material | Grade has to be imported | Ask for material lead time as a separate line |
| First article | Fails on a feature nobody discussed | Name the critical features on the drawing |
| Production | Silence, then a late date | Agree on progress updates in writing |
| Delivery | Duty and freight surprise | Confirm the delivery basis on the quote |
None of these is exotic. They are all a question asked too late.
If you would rather not run it
That is the entire reason we exist. You send the drawing, we quote it within 24 business hours, and if you order we place it, watch it, measure it and ship it. One contact for all of it.
A checklist for the first purchase order
Print this and work down it before the order goes out.
- Drawing revision named on the purchase order and matching the quote
- Material grade, condition and whether a local equivalent is acceptable
- Quantity this order and expected annual volume
- Critical features identified, general tolerance note in the title block
- Finish specified with a standard, and what must be masked
- First article defined: how many pieces, measured how, reported how, approved by whom
- Your approval turnaround agreed, because it sits inside the lead time
- Payment terms, currency and the account name
- Delivery basis and who handles duty
- What happens to a non-conforming part, in writing
- Packing requirement, including rust prevention for ferrous parts
- NDA in place if the design is sensitive
Twelve lines. Every one of them is cheap now and expensive in six weeks.
What good looks like in the first two weeks
A supplier worth keeping does three things early: asks a specific question about your drawing rather than confirming everything is fine, states the lead time with a starting point rather than a bare number, and tells you about a problem before you ask. If none of those has happened by the time the first article ships, you are being managed rather than supplied.

Questions we get on this
Do I have to set up a company in Vietnam to buy parts there?
No. You buy from a supplier who invoices you internationally. If you buy from us, you place one purchase order with us and receive one invoice, and you never open an account with a machine shop.
How do I pay a supplier in Vietnam?
By international transfer to a company bank account, normally a deposit with the balance before shipment on a first order. A request to pay a personal account is the point at which you stop the conversation, with any supplier in any country.
How long does a first order take?
Plan on a week for quoting and drawing clarification, two to five weeks for machining and finishing depending on the part, and then your freight. The variable that moves most is material availability, not machine time.
Have a part like this?
Send the drawing. We shortlist the shop we place it with that run the process and material, and answer within 24 business hours.
