"Why is the MOQ 5,000 when I only need 500?" is the single most common question we answer. Here is what actually sits behind that number — and how buyers work around it.

Why MOQs exist at all

Glass bottles are not stamped out like plastic parts. A bottle furnace runs continuously at around 1,500 °C, and a production line is tuned for one bottle at a time. That creates four fixed costs per run:

  • Line changeover — adjusting the IS (individual section) machine, gobs and mould temperature takes hours, and the first pallets off a new run are usually scrapped or downgraded.
  • Mold cost — a new bottle and cap mold set costs roughly ¥15,000-60,000 depending on complexity. Spread over 500 pieces that is ¥30-120 per piece of mold alone; spread over 50,000 it disappears.
  • Decoration setup — screens, pads, jigs and a Pantone color proof are made once per artwork, not per piece.
  • Quality risk — short runs are disproportionately likely to be rejected at AQL inspection, because there is no volume to absorb defects.

The three MOQ tiers you will see

Why there is no 100-piece tier. Plenty of suppliers advertise one. In glass it usually means a decorated bottle bought in from a trading company, not a bottle off a furnace. We do not run it, and the reason is freight rather than production. Five thousand small bottles is roughly one cubic metre, and one cubic metre is the smallest volume an LCL carrier will bill you for. Below that you still pay for a full cubic metre, so the per-bottle freight climbs steeply — a 500-piece order can end up costing more per bottle than a 3,000-piece one. A short run is not a cheaper way in; it is the same freight spread over fewer pieces.

Tier 1 — Existing mould (3,000 pcs). The factory already holds the mould and has run it before. No mould fee, no sampling cycle, standard lead time. This is where most private-label projects sit.

Tier 2 — Post-processing (5,000 pcs). When the bottle has to be screen printed, spray coated or frosted, the decorated quantity starts at 5,000. Decoration carries its own setup — screens, a colour proof, jigs — and its own reject rate, and the run has to absorb both.

Tier 3 — New mould (10,000 pcs). Your shape, your name. 25–35 days to first sample and 45–60 days to mass production. Justify it with a forecast, not enthusiasm.

How to make a small order work

  • Reuse a stock mold and spend your budget on decoration and packaging instead — a plain bottle with your print on it looks more custom than a new shape nobody stocks.
  • Split the order by component: buy bottles at tier 2 and caps separately later, so one delayed component does not hold the whole shipment.
  • Consolidate SKUs: three colors of the same bottle at 2,000 each often prices like 6,000 of one.
  • Negotiate on annual volume, not first order: "2,000 now, 20,000 this year" gets better terms than begging for a 500-piece break.

MOQ and unit price move together

Expect the unit price to roughly halve between 3,000 and 50,000 pieces on a stock mold, then flatten. The curve means the cheapest per-piece order is rarely the cheapest project — unsold inventory at a low unit price is still unsold inventory.

A realistic first-order plan

Test with 300-500 stock pieces, one decoration variant. If it sells, move to a 5,000-piece run on the existing mold. Only commission a new mold once you can point at three months of reorder data. That sequence costs less than one wrong new-mold order — and most successful brands arrived at their signature bottle exactly this way.
