Small batch and low-volume manufacturing: MOQ, tooling, lead time and landed cost

Confidence 4/5 Established practice

The honest answer to "can I manufacture 100 units in China" is yes, but not by the process you were picturing. Small runs work when the process has low fixed cost — machining, silicone, sewing, simple assembly — and fail when it does not, because at low volume the set-up cost is spread over too few units. The correct move is usually to change the process for the first run and change it back when volume arrives.

Quick answers

Minimum order quantityAs low as 1 for machining, 3D printing and hand assembly. 50–200 for silicone and cut-and-sew. 300–1,000 where a printed plate or a simple tool is involved. 1,000+ for injection moulding and die casting, because those tools are the expensive kind.
Lead timeSmall runs are dominated by set-up rather than production: usually the same 7–20 days of preparation as a large run, with fewer production days.
ToolingThe whole point of small-batch is avoiding a hard tool. Soft tooling — silicone moulds, urethane casting, printed jigs — costs USD 100–800 and may last a few hundred parts, which is often enough to validate demand.
Unit costExpect two to five times the volume unit price, and expect the set-up to be a visible and separately quoted line rather than hidden in the unit cost. That visibility is the point: it tells you what volume would buy.
HS classificationDepends on the process, not the order size. Small machining runs are classified by the finished part exactly as a large run would be: 7326.90 for other iron or steel articles, 7616.99 for other aluminium articles. Volume changes the price and the process, never the classification.
CertificationUnchanged by volume. A sample unit and a production unit need the same compliance, and a small first order is the cheapest possible moment to discover a certification requirement.
DutySmall shipments can fall under a destination country's de minimis threshold and clear duty-free, while the same goods in a larger quantity attract duty and formal entry. The US threshold is USD 800 per shipment and the EU has its own low-value regime with VAT treatment that differs from duty treatment. This can change the landed cost of a trial run fundamentally, so it is worth checking the threshold for the specific destination before concluding that a small run is disproportionately expensive.

Common mistakes

  • Choosing a process because it is the one the factory has, rather than the one the volume suits.
  • Letting set-up cost hide inside the unit price, which makes the volume trade-off invisible.
  • Re-tooling at the crossover instead of planning the transition in advance.
  • Assuming a small order gets the same attention as a large one; it needs a factory for which it is not trivial.
  • Overlooking de minimis thresholds, which can change the entire landed cost for a small shipment.
