1. Start from your volume, not from the biggest factory you can find
Your order size decides which tier of manufacturer can serve you. Below 300 pieces you are looking at workshops and small-batch producers; between 300 and 1,000 you reach factory pricing; above that, freight and packaging logistics start to matter as much as unit cost. Contacting factories far above your tier wastes weeks: they will either decline the minimum or quote a price that makes the effort pointless.
Also be honest about whether this is a one-off or a product line. A manufacturer that expects repeat orders will invest more in the pattern and the relationship; one that expects a single run will optimise for getting it out the door.
2. Check which design files the manufacturer actually accepts
Manufacturers differ in what they can work from. Some accept only finished 2D artwork; others take rough sketches, photo references, or a physical sample; a few ask for a tech pack with dimensions and material specs. The more raw your input, the more you depend on the factory's pattern team — and the more revision rounds you should expect.
If your design is a single front view, a manufacturer that lists character plush or mascot expertise will usually know what questions to ask about depth and proportion. If it accepts anything without questions, that is a warning, not a convenience.
3. Compare sampling on identical terms
Ask every candidate the same four sampling questions: what does the sample cost, how many days does it take, how many revision rounds are included, and is the fee credited against the production order. Quotes that look cheaper often include fewer revisions, so the real cost appears on the second adjustment.
The sample is also your only real evidence of the factory's pattern quality. Judge proportion, seam placement, embroidery density, and whether the character reads at arm's length — not the colour, which is a fabric-lot question and should be confirmed separately.
4. Verify certifications for your destination market
Certification requirements follow where you sell. For the EU you need EN71 conformity and CE marking; for the US, ASTM F963 and CPSIA; other markets have their own schemes. Ask candidates for the actual test reports — product photos, standard, laboratory, and date — not a logo strip on their homepage.
Do this before sampling, not after. A factory that cannot supply the right report for your market is not a candidate, no matter how good the sample looks.
5. Look at who the manufacturer already serves
A factory's existing clients tell you what kind of project it is set up to handle. If it works with licensed IP, it will have procedures for approvals and confidentiality; if it works with startups, it will be used to small runs and incomplete briefs; if it only serves promotional buyers, it will optimise for deadline and price rather than character accuracy.
If your character is unreleased, ask for an NDA before you share the artwork. Manufacturers who handle licensed work will have a template and will not be surprised by the request.
6. Read how they communicate before you pay
The response to your first email is a preview of the whole order. Do they ask clarifying questions about size, quantity, and destination? Do they answer the actual questions, or reply with a catalogue? Is there one named contact, and do they write in the language your brief was written in?
Production problems are normal; communication determines whether they cost a day or a shipment. A factory that is vague before the deposit will not become precise after it.
7. Red flags worth walking away from
Treat these as disqualifying: a quote with no specification attached; refusal to produce a physical sample; a demand for full payment upfront; no verifiable factory address or legal entity; certifications that cannot be produced as documents; and pressure to decide today. Any one of these can be explained away, but together they describe a supplier you cannot audit.
The inverse signals are just as useful: a factory that asks good questions, quotes with a clear spec, offers a staged payment tied to sample approval, and volunteers the limits of what it can do.
8. Brief three manufacturers and score them the same way
Send one brief — artwork, target quantity, size, destination market, deadline — to at least three candidates and ask each for the same six things: unit price at your quantity, setup and sample fees, sample turnaround, production lead time after approval, certifications held for your market, and the Incoterms they quote on. Then compare landed cost, not just unit price.
A structured comparison beats a feeling. The factory that answers all six precisely is usually also the one that will handle the production order precisely.
