Small-batch manufacturing in China: how minimum order quantities really work

A minimum order quantity (MOQ) is the smallest order a factory will accept for one item, and it exists because part of the cost of every production run is fixed whether you order 50 units or 5,000. Small batches in China are realistic when the process needs little set-up, such as CNC (computer numerical control) machining, circuit board assembly, digital printing or stock products, or when you pay the set-up cost as a separate line.

This guide is general information and does not constitute legal or engineering advice; the factory or a test laboratory confirms what applies to your specific product.

Where a minimum order quantity comes from

Alibaba’s seller blog defines MOQ as “the lowest number of units a wholesale supplier allows buyers to purchase at one time” and says suppliers usually start from the product’s break-even point, then set the minimum above it to leave a margin (Alibaba.com). Four costs drive that break-even point.

Material minimums. Suppliers of raw material have their own lot sizes. Mills that weave and dye fabric set their own minimums and charge more for small runs because their machines run at a fraction of capacity (Visionise).

Machine set-up. A packaging maker describes one printed mailer job: two printing plates costing USD 1,300, about five hours of set-up for two people, and roughly 3,000 mailers’ worth of material spent before the print is right. The run itself then takes about two hours (EcoEnclose).

Tooling amortisation. Tooling means moulds, dies and fixtures made for your part. Its cost is divided across every unit you buy, so a small order carries a large share per unit.

Packaging print runs. Branded boxes, labels and manuals each run on their own set-up, so each can carry a minimum separate from the product’s.

MOQ by process

The pattern: processes without a part-specific mould or plate suit small batches, and a minimum climbs each time something is made for you alone.

How quantity and unit price trade off

Fixed cost divided by quantity gives the set-up share of each unit. Formlabs published one worked case: a mould for a small plastic latch cost USD 3,600, and 1,000 moulded parts cost USD 3,920 in total, against USD 600 for printing them in-house. For that part, moulding only became cheaper at 13,050 units (Formlabs). Formlabs sells printers, so read its figures with that in mind. Xometry, which offers both processes, puts the usual break-even between 250 and 2,000 parts (Xometry).

The same logic applies when a factory accepts a small order. An apparel maker notes that “no MOQ” offers “typically come with significantly higher per-unit pricing” (Visionise). The set-up cost is built into the unit price.

Legitimate ways to lower the minimum

Use stock materials and colours. Since cut-and-sew minimums count per colour, three colourways of one style triple your commitment. One standard colour keeps you at the base minimum.

Start from an ODM base or shared tooling. If the factory already owns a mould for a similar product, you avoid a new mould and its amortisation. Our guide to private label and contract manufacturing models explains who owns the design and tooling in each.

Pay set-up as a separate line. JLCPCB itemises its assembly set-up fee (USD 8.18 for its economic service, from USD 25.56 for standard) and stencil fee (JLCPCB). Ask other factories to itemise moulds, plates and line set-up the same way. Once set-up is paid, the factory has less reason to insist on volume. If you pay for a mould, put its ownership in writing.

Cut variants. Every extra size, colour, logo position or box version can carry its own minimum.

Ask for a sample run or trial order. Alibaba’s blog suggests asking whether a few units can be bought at retail price for testing (Alibaba.com). Visionise notes that the total order minimum generally does not apply to reorders, only the per-style one.

Low-volume routes before mass production

Prototype shops are on-demand manufacturers, such as Protolabs or Fictiv, that make parts in small quantities by CNC machining, 3D printing or quick moulding.

3D printing, or additive manufacturing, builds a part layer by layer from the digital file, with no mould at all. It wins at low quantities and loses once mould cost is spread thin, as the break-even figures above show.

Bridge tooling, also called soft or prototype tooling, is a mould in aluminium or unhardened steel with a limited life, used to make sellable parts until the production mould is ready. Fictiv puts its cost at 20 to 40 percent of a production tool and its range at up to about 10,000 units, with urethane casting, where resin is poured into silicone moulds, covering 1 to 300 units (Fictiv).

These routes often come before a Chinese factory. Aslan has no engineers, design service or test laboratory, so prototyping belongs with a prototype shop or design firm. Our injection moulding and CNC machining page covers the move to factory production.

Warning signs when a factory accepts any quantity

• The unit price barely changes between 50 and 5,000 units. Set-up cost is either hidden or the goods are stock from elsewhere.
• No mould, plate or set-up cost appears for a custom part.
• The supplier will not say where production happens. A 2011 article by a quality consultant warned that intermediaries get small runs made “in small workshops that are desperate for business” (QualityInspection.org).
• Visits and audits are refused. See how to verify a Chinese supplier and what a factory audit checks.
• The sample came from a different source than the production line will.

Aslan’s typical buyers spend from about EUR 200,000 a year, and a very small first order is usually better served by a prototype shop or a ready-to-ship supplier. For volumes that justify a factory search, see pricing.

Checklist for negotiating a minimum

• Ask for the MOQ per item, per colour, per size and per packaging version.
• Ask for moulds, plates and set-up as separate, itemised costs.
• Get unit prices at several quantity breaks, and compare total cost.
• Ask which materials and colours the factory keeps in stock.
• Ask whether an existing ODM product or mould can serve as your base.
• Put mould ownership and return terms in the contract.
• Agree the trial quantity and the reorder minimum before the first order.
• Approve a sample made on the production line.
• Confirm you are dealing with the factory that makes the product.
• Work out the landed cost at your real quantity.
