Sample to mass production: why schedules slip and how to protect the date

Published 2026-10-13 · 6 min read

Most first orders do not miss their date because the factory is slow. They miss it because the artwork was approved late, or because the sample came back and three people each wanted one more change. Here is the sequence we actually run, the three clocks hidden inside one delivery date, and the two things a buyer can hold a supplier to.

There are three clocks inside one delivery date

On a custom order there is not one lead time, there are three. Sampling takes 7-10 working days after your artwork is approved. Mass production takes 7-12 days after you approve the sample. Packing and final inspection add another 3-5 days. Suppliers usually quote you the sum of those windows, and buyers usually hear it as “about four weeks from today”.

The clock that matters is the one that starts last. Sampling cannot start while the logo file is still being redrawn; production cannot start before a signed sample exists; packing cannot start before the retail artwork is final. Until those decisions land, an order is queued, not started. When an order slips by two weeks, it is almost never because injection moulding suddenly took two weeks longer.

There is one shortcut worth knowing. If the model is already on tooling, no new mould has to be cut, and the sample window is that much more predictable. We run 21 models on existing tooling, so for those the sample date is a schedule question rather than a tooling question. A brand-new shape is a different project: it needs a new mould, it has its own development time, and it is quoted separately before anything starts.

Where first orders actually slip

In our own orders the delay is nearly always a decision, not a machine. Five show up over and over. The artwork arrives after the sample fee is paid, so the sample clock starts late. The colour is approved on a screen and then questioned in daylight. The packaging method is left open until the goods exist, which is the most expensive moment to choose it. The sample is approved by a committee, so a two-day decision becomes a two-week one. Or the deposit and the purchase order arrive after the sample, so the production window starts later than everyone remembers.

None of these are factory problems, and all of them are fixable with one rule: whoever can say yes should be in the first email, not in the fifth.

How to protect the date from your side

Freeze the version you approve. When you sign the sample, that sample becomes the reference for the whole batch: colour, material, magnet, printing and packaging. Keep it, and ask us to keep ours. If something changes after that point, it is a new version and the production window restarts, which is the honest way to treat it rather than absorbing a silent change into the batch.

Name one decision maker. A single person who can approve artwork and packing is worth more to your schedule than a faster factory. Ask for a digital mock-up and approve it by email rather than waiting for the physical sample before you look at the layout.

Tell us the launch date in the first email. If we know the date a container has to leave, we can tell you honestly whether the model you picked can hit it, and which of the three clocks is the risk. That is a different conversation from “how long does it take”, and it is the one that saves the shipment.

Finally, put one thing in writing: what happens if the batch is late or a part of it fails inspection. Rework and replacement rules agreed before the deposit are worth far more than a friendly “no problem” after it. We sign an NDA whenever your own design is involved, and we would rather argue about a clause in the quotation than after loading.

What we will not promise

We will not promise a date that depends on artwork nobody has approved or a deposit nobody has paid. We do not hold stock of your custom colour, so we cannot promise a replacement overnight if the first batch is short. We will not put a number on tooling time for a structure we have not seen; if you need a new shape, the mould is quoted as its own project, 4-6 weeks of development, and it starts only when you accept that quotation.

We also do not claim certifications we do not hold. We do not hold CE, RoHS, REACH or SGS certificates, and we say so before you ask, rather than letting a certificate-looking logo do the talking. What we do hold in China: 8 granted patents (CNIPA) — 5 design patents and 3 utility models — a registered trademark (no. 80143576, Class 9) and a copyright registration. If your market needs test reports, raise it at RFQ stage so the sample plan can include the testing instead of discovering it at the port.

Questions buyers ask about delivery dates

How long does a sample take?

7-10 working days after your artwork is approved. If the model is already on tooling, no new mould has to be cut, so the date is a scheduling question rather than a tooling one.

How long is mass production?

7-12 days after you approve the sample, plus 3-5 days for packing and final inspection. Goods ship FOB Shenzhen.

What is the MOQ, and does it include custom logo and packaging?

50 pcs per model, and that price includes your logo, colour and packaging. 21 models are already on tooling, so those start at that quantity.

What if I need a new shape that is not in your range?

That is a separate project: a new mould with its own development time, quoted before anything starts. We do not put a date on a structure we have not seen.

Do you hold CE, RoHS, REACH or SGS certificates?

No. We do not hold those certificates and we say so up front. If your market requires test reports, tell us at RFQ stage so the sample plan can include them.

Which part of the delay is usually the buyer's?

Artwork, packaging choice, and approvals shared between several people. In our experience those three account for most of the lost days, not moulding or assembly.
