A European buyer tends to picture China as one large factory. The reality is a mosaic of towns that each became very good at one thing, over thirty years, with the component suppliers, the toolmakers, the skilled labour and the logistics that go with it. Sourcing inside the right cluster gives you better prices, shorter lead times and real technical conversation. Sourcing outside it gives you a factory that will try, and subcontract the part it cannot do.
What a cluster actually gives you
- Component depth. The part you need is available locally, in the quantity you need, without a two-week wait.
- Competition between suppliers. Ten workshops within a few kilometres discipline the price better than any negotiation.
- Accumulated know-how. The problem you are about to discover has been solved there a thousand times.
- Tooling nearby. A mould modification takes a day, not a fortnight of shipping back and forth.
How to find your cluster
Do not start from a supplier list. Start from the question « where is this category made? » and answer it by looking at where the trade fairs for your sector are held, which towns appear repeatedly in the addresses of suppliers in your category, and what the local industry associations exist for. Ten suppliers in the same unfamiliar-sounding town is not a coincidence; it is your answer.
When your product spans two clusters
Many products do: the electronics in one place, the metal housing in another, the textile part somewhere else. You then have a choice between one assembler who buys from both — simpler, one contact, less control — and managing two suppliers yourself — more control, more coordination, and a quality problem that becomes an argument about whose fault it is. For a first product, one assembler is almost always the right call.
Specialisation does shift: rising costs push categories inland or abroad over time, so a map that was accurate five years ago is a starting point, not a reference. Verify where your category sits today rather than where an article said it sat.
