How to read these ranges
Minimum order quantities and lead times for smart glasses depend on three things: how much of the product changes, how many partner plants are involved, and how much testing the target markets require. The ranges below come from published supplier terms and catalog listings across the category and from the way programs are usually structured. They are typical reference ranges, not quotes, and every program gets its own figures confirmed in writing after the brief and the shortlist. For the reasoning behind the numbers, read smart glasses OEM and MOQ explained.
The minimums exist for practical reasons. A catalog model already has its board, moulds and test reports, so a partner plant can run a small lot from components it holds. A logo program adds printing plates, packaging runs and an app skin, each with its own setup. A full custom program adds new tooling, acoustic tuning and firmware work that only make sense over a larger batch. Lead times follow the same logic: the more that changes, the more sample rounds and test steps the program needs.
Typical MOQ by route and line
| Route or line | What is included | Typical MOQ |
|---|---|---|
| Catalog model | Existing model, stocked colours and lenses | 50-500 pairs per model |
| Logo program | Logo print or laser mark, retail box, app skin where available | 500-1,000 pairs per model |
| Full custom OEM or ODM | New frame mould, acoustic and PCBA tuning, app white-label | From 3,000 pairs per model |
| Accessories | Replacement lenses, charging cases | 500-1,000 pieces |
| Kids line | Kids frames and fit, volume limits per firmware | From 1,000 pairs per model |
MOQ is set per model, and in most programs colours within a model can be split once the model minimum is reached, subject to the partner plant's colour minimums. Lens variants on one front often count toward the same model. The difference between the routes is explained on OEM and private label.
Typical lead times from sample to shipment
| Stage | Catalog | Logo | Full custom |
|---|---|---|---|
| Samples | 5-10 working days | 10-15 working days | 30-60 days engineering sample, including 25-45 days tooling |
| Certification testing | Often reuses existing reports, per lab review | Often reuses existing reports, per lab review | Typically 3-6 weeks for FCC and CE lab testing, per lab and scope |
| Batch production | 20-35 days | 20-35 days | 45-75 days, excluding certification queues |
| Courier or air | 5-10 days | 5-10 days | 5-10 days |
| Sea FCL or LCL | 15-25 days US West Coast; 30-45 days Europe | Same | Same |
The 3-6 week certification window is an estimate for lab testing time and depends on the lab's queue, the scope (radio, EMC, safety, RF exposure, EN 18031 cybersecurity) and whether retesting is needed. Bluetooth SIG listing is handled per application. The test routes are on compliance and certifications.
What makes a program faster or slower
Most delays come from decisions, not from production. The common ones are:
- Artwork and packaging approval: printed boxes and manuals need final files before the golden sample is signed; late artwork delays the batch more than any production step.
- Changes after the golden sample: any change to the board, speaker port or front after sign-off restarts part of the sample cycle and may affect test reports.
- New tooling: moulds take 25-45 days and usually need one or two rounds of correction before the fit is right.
- Certification scope: adding markets, a camera module or a new antenna layout widens testing.
- Component availability: chipsets and cells can have their own lead times, which partner plants confirm when the spec sheet is fixed.
- Calendar: national holidays in China, especially around the Lunar New Year, pause production and shipping for several weeks.
The desk builds the program timeline backwards from the target arrival date and confirms each milestone with the partner plants before the deposit stage.
Planning a first order
For a first order, many brands start on the catalog or logo route with one or two models, test sell-through and returns, and move to a full custom program once the range is proven. That path keeps the first commitment within 50-1,000 pairs per model and lets the golden sample and test reports from the first program carry into the next. The sample process is described in the smart glasses sample process, and the full sequence on sourcing process. Shipping options and battery rules are on logistics and shipping.
