OEM and ODM get used loosely in supplier conversations. For a buyer, the difference is who owns the design, tooling, and the risk when something changes.
This article does not name specific factories. Use it as a checklist, then confirm against each company’s own documents — website, quotation, and any certificates they send as files.
A useful rule: if a factory cannot say which model they are quoting on this order, you do not yet have a comparable quote.
OEM
Original equipment manufacturing usually means: you bring the design (or a licensed design), they manufacture to spec.
Ask:
- Who owns the tooling?
- Can they run your BOM, or do they substitute materials?
- What is the sample lead time for this product, not a catalogue item?
ODM
Original design manufacturing usually means: they already have a design or platform; you brand it, tweak it, or pick from a range.
Ask:
- What is actually customisable — colour, logo, structure?
- Are you exclusive in your market, or is the same base product sold elsewhere?
- Who is liable if the design infringes?
Mixed models are common
Many Vietnamese manufacturers will do both. That is fine if you know which model you are buying on this order.

What to put in your brief
Whether you want OEM or ODM, say so up front, with quantity and destination market. Put it in the RFQ so every factory answers the same question. You can describe that on the homepage and we will help shortlist suppliers that match.
If you are comparing quotes later, keep the OEM/ODM choice, the quantity, and the destination market in one place. That is what makes two quotations actually comparable.
