OEM or ODM: what can be changed, and what it costs in time
OEM and ODM get used interchangeably in enquiries, which is how a buyer ends up expecting a structural change on a four-day sample schedule. The useful distinction is not the label but the layer being changed — and each layer carries a different lead time, a different set of files you have to supply, and a different point at which the decision becomes expensive to reverse.
01 · The distinction that matters is the layer, not the label
OEM, in the way it is used here, means an existing model carrying your brand: a housing in your colour, your mark on the unit, packaging to your artwork, and consumables under your label. The engineering is unchanged. ODM means the unit itself changes — housing form, configuration, interface — and that is where the schedule jumps from days to months.
The question worth asking is not "can you do OEM". Almost anyone can print a logo. It is which layer you actually need, because most enquiries that start as ODM turn out to need OEM plus one packaging decision.
02 · Four layers, and what each one asks of you
| Layer | What changes | What you send | Typical lead time |
|---|---|---|---|
| Housing colour | Colour matched to a reference | Pantone or RAL code, or a physical swatch | Sample before the run |
| Logo | Mark on the unit | Vector (AI / EPS / SVG), or PNG at 1000 px minimum on transparent background | With the sample |
| Packaging | Carton, flight case or wooden case, inserts | Print-ready file with dieline, or a brief | Artwork signed off before production |
| Consumables | Cartridges, gels, probes or pen heads under your label | Artwork and the specification you want held | Per order |
| Structure / electronics | Housing form, configuration, interface | A development brief and a target specification | One to two months, prototype to production |
The first four rows are OEM. The fifth is ODM, and it is the one that changes the shape of the project. Everything above it can be quoted from a reference; the fifth cannot, because it has to be designed.
03 · Colour is not a screenshot
Screen colour is not a reliable reference for a painted housing. Send a Pantone or RAL code, or post a physical swatch. We produce a matching sample and send photographs for approval before mass production, and the sample exists precisely because the render on your monitor will not match the unit in your hand.
The same logic applies to logo placement. There is a blank brand plate on the housing, and where your mark sits on it is confirmed on your unit before the run — not inferred from a drawing.
04 · The schedule is set by approvals, not by the line
An OEM order runs in eight steps: enquiry, quote and sample plan, sample build, sample approval, branding artwork sign-off, mass production, pre-shipment check, shipment. A stock-configuration sample takes three to five working days. Mass production is not the slow part.
What actually sets the date is the approval loop. Every revision returns the job to the sample step, and a colour that is nearly right costs another round. Buyers who send a physical swatch and vector artwork in the first message routinely finish a month ahead of buyers who send a screenshot and iterate.
| Step | What happens | Who it waits on |
|---|---|---|
| 01 Enquiry | Models, volumes and market | You |
| 02 Quote and sample plan | Ex-works pricing, sample schedule | Us |
| 03 Sample build | 3–5 working days for stock configurations | Us |
| 04 Sample approval | You test it; revisions return to step 03 | You |
| 05 Branding artwork | Logo, colour and packaging signed off | You |
| 06 Mass production | Built on our lines, multi-stage QC | Us |
| 07 Pre-shipment check | Test video and packing photographs sent | You |
| 08 Shipment | Carton, flight case or wooden case, documents | Both |
05 · Minimum order, and what it is for
Minimum order is one unit, OEM included. That is deliberate: a branded sample is how a distributor tests a market before committing to a container, and how a clinic checks that the colour it approved is the colour that arrives. The sample carries the same pre-dispatch check as a production order — test video and packing photographs before it ships, as described in what we check before your order leaves the factory.
06 · Where customisation stops
Four things are not on the table, and it is better to know them at the start. The certification documents cover the model as tested — a structural change can put the unit outside the scope of the report, which is one reason ODM takes as long as it does. Electrical ratings are fixed by the platform, so voltage and plug change per market but output does not. Safety features are not removable. And the treatment parameters of a device are not a branding decision.
07 · What to send in the first message
Five items turn three rounds of questions into one reply: a colour reference (Pantone / RAL or a physical swatch), logo artwork (vector, or PNG at 1000 px minimum on transparent background), packaging artwork or a brief with a dieline, the destination markets so labelling and documentation can be discussed, and volumes — sample quantity plus the repeat volume you are planning.
08 · Where to look next
The full scope, artwork checklist and timeline are on customization. The plant that builds the order is described on factory, and the compliance framework on certifications.
