How Sourcing From Vietnam Works, Step by Step
October 27, 2026
Sourcing from Vietnam is a sequence of decisions, and each one is cheaper to get right early. This is how a typical project runs and what you can prepare at each stage.
Stage 1: The brief
Everything downstream depends on the brief. A good one has:
- Drawings or 3D files, with tolerances and finish called out
- Material and any standard it must meet
- Quantity per order and per year
- Packaging and labeling needs
- Target delivery terms (FOB, CIF or DDP)
- The date you need the first shipment
A vague brief produces vague quotes that cannot be compared. If you are not sure about a spec, say so. A good partner will ask the right question instead of guessing.
Stage 2: The shortlist
Match the brief to factories that already do this kind of work. You want two or three, each with a capability profile, a view of capacity and an indicative price. More than three rarely helps. It slows decisions and spreads your drawings further than needed.
This is also the stage to sign an NDA, before drawings leave your hands.
Stage 3: Samples and approval
Samples are the first real test. Ask for samples made on the production line with production material. Measure them against the drawing, and agree in writing what is acceptable before tooling or the first batch is released.
For molded parts, this is where tooling is built and tried out. Expect more than one round, and plan for it.
Stage 4: Production and quality control
Inspection at set points does more than inspection at the end:
- Before production: material, tooling and setup are checked against the approved sample.
- During production: a sample of finished parts is checked while there is still time to fix the process.
- Before shipment: a final check using AQL sampling decides whether the lot goes.
Payment milestones are tied to these points, so the factory has a reason to finish each one properly.
Stage 5: Shipping and after-sales
Agree the shipping terms early. Under FOB, you take over at the port. Under DDP, the seller handles delivery and duties. Make sure export documents are ready before the container is: commercial invoice, packing list, bill of lading and any certificate of origin your customs broker needs.
Keep the first-article report, inspection reports and photos. If a problem shows up later, they are the evidence you need.
Where a sourcing partner fits
You can run all five stages yourself. Most buyers who do it well have someone in Vietnam, or enough volume to justify travel. A sourcing partner covers the same stages for you: shortlist, audit, sample checks, inspections and shipping coordination, with one contact on your side.

Frequently asked questions
How long does it take to source a part from Vietnam?
It depends on the part, tooling and sample rounds. The brief and shortlist stages usually take days to a few weeks. Tooling, samples and approval add more. Ask for a timeline per stage rather than one total number.
What should be in a sourcing brief?
Drawings or 3D files, material, quantities per order and per year, tolerances, finish, packaging, target delivery terms and the date you need the first shipment.
Do I need an inspection if the samples were good?
Yes. A good sample shows the factory can make the part once. Inspection during and before shipment shows it can make the whole batch the same way.
