Most guides about importing from China start at "find a supplier" and end at "book a container." That works when you are buying something that already exists on a shelf. It does not work when you are having something made — your design, your materials, your logo. This article is for business owners and product managers launching their own product or private label in commercial volumes: from roughly 500–1,000 units, or a container upward. Below is the real sequence a factory order goes through, what each stage costs, and where the money leaks when a stage gets skipped.
Stage 1. The specification, not the idea
A factory does not manufacture ideas. It manufactures a document. Everything that is not written down — the exact polymer grade, the coating thickness, the tolerance, the shade of the plastic, the screw type — will be decided by the factory in its own favour, and it will be legally right to do so. This is why the first stage is not "find a factory," it is writing a spec sheet: materials, dimensions with tolerances, finish, function tests, packaging, labelling, acceptance criteria. How to build one is in the technical spec sheet for a Chinese factory.
Rule of thumb: if a stranger could not manufacture your product from your document alone, your document is not finished.
Stage 2. Finding a factory for the process, not the product
Beginners search for "a factory that makes X." Buyers search for the process X requires: injection moulding, stamping, die casting, extrusion, CNC machining, assembly. A single product often crosses two or three processes, which is why the "factory" that quotes you fastest is so often a trading company that farms the work out — with a margin and no control. How to tell the two apart is in factory or trader, and the legal and on-site checks we run are in our factory verification protocol.
Stage 3. Quotation and tooling
Here the project meets its first real invoice. Unit price is easy; the number that decides whether the project makes sense is the tooling — moulds, dies, fixtures, jigs. Tooling is paid once, up front, before a single sellable unit exists, and it is the single most misunderstood cost in the whole chain, including the question of who legally owns it afterwards. We covered it in full in tooling and moulds in China: cost and ownership.
Expect the factory to come back with change requests at this stage. That is not obstruction — it is design for manufacturing, and most of those requests are worth accepting. Some of them quietly cheapen your product; those are not.
Stage 4. Samples: prototype, pre-production, golden sample
Samples are not one thing. A 3D-printed prototype proves the shape. A tooling sample proves the mould. A pre-production sample, made on the real line with the real material, proves the product. And one approved, signed, sealed unit becomes the golden sample — the physical reference every later batch is measured against. Skipping straight from "the sample looked great" to mass production is exactly how the classic failure happens: the sample is fine, the batch is defective. The full ladder is in sample types: prototype, PP sample and golden sample.
Stage 5. The pilot run
A pilot run is a small production batch — often 5–10% of the order — made under real conditions before the line is committed. It surfaces the problems no sample can: cavity-to-cavity variation, assembly-line defects, packaging that fails on the pallet, cycle-time reality versus promise. It costs a fraction of the order and it is the cheapest insurance in the process. See the pilot run before mass production.
Stage 6. Mass production and inspection
Once the line is running, control shifts from documents to physical presence. During-production inspection catches a drifting batch while it can still be fixed; pre-shipment inspection at 80% completion is the last moment leverage exists, because the balance payment has not been released yet. The types and timing are in quality control when importing from China, and the reason to visit before releasing the balance is in factory inspection before the balance payment.
Stage 7. Packaging, labelling and barcodes
Packaging is a development project in its own right, not an afterthought at the end. Retail box, inner carton, master carton, drop test, moisture protection, barcodes, country-of-origin marking, the label your customs authority expects — all of it has to be specified, sampled and approved like the product itself. Details in packaging development in China.
Stage 8. Shipping
Only now does the part everyone thinks of as "importing" begin: loading plan, mode, documents, customs. If the product is bulky, the packaging decisions from stage 7 have already determined how many units fit in a container — and therefore your landed cost per unit. That arithmetic is in landed cost of a China import.
How long it all takes
- Spec sheet and factory search: 2–4 weeks
- Quotation and tooling: 3–6 weeks for a simple mould, 8–12 for a complex one
- Samples and approvals: 2–5 weeks, more if revisions are needed
- Pilot run: 1–2 weeks
- Mass production: 20–45 days depending on volume and season
- Sea freight: 30–50 days on the main routes
A realistic first-batch timeline from signed spec to warehouse is four to seven months — longer if it crosses Chinese New Year. Repeat orders drop to production plus shipping, because the tooling and the golden sample already exist. The seasonal traps are in production lead times in China.
The three stages importers skip — and what it costs
- Skipping the spec sheet. You receive something that technically matches what you asked for and commercially matches nothing you can sell.
- Skipping the pre-production sample. You approve a hand-made unit and receive a line-made one. Different object.
- Skipping the pilot run. The defect that would have cost you 200 units now costs you the container.
Manufacturing in China is not risky because factories are bad. It is risky because every unwritten detail becomes the factory's decision, and every skipped stage moves the discovery of a problem further downstream — where it is measured in containers instead of samples.
Building your product in China
We run this whole chain for clients: writing the spec with you, finding factories by process, negotiating tooling and its ownership, running samples and the pilot batch, inspecting production, and handling packaging, freight and customs. Over seven years that has meant 3,500+ deliveries and 340+ verified suppliers — real examples are in our case studies.
Start with product sourcing and supplier verification, or go straight to private label manufacturing if the product already exists and only the brand is yours.
