Do I have to visit in person?

For a first order, it is strongly advisable. A site visit closes most of the risks that correspondence hides.

Are clusters only in China?

No. Turkey, India, Vietnam, Italy, Poland, Mexico and Brazil all have strong specialised hubs, often with shorter shipping legs.

How do I tell a manufacturer from a middleman?

Ask about tooling, defect rates and line load. A middleman gets vague and cannot show the workshop on an unscheduled video call.

What if the cluster lacks the technology I need?

Look at the adjacent cluster: that operation is often done in the next city and simply subcontracted.

Industrial clusters: sourcing by hub instead of by factory

Updated 2026-09-16 · 8 min read

Short answer: almost any mass-produced item is made in a few dozen places on earth. Knowing your cluster shrinks the search from “all of China” to one city and three streets. A cluster beats a random factory because competitors, subcontractors and freight forwarders all sit within an hour’s drive.

What a cluster is and why it saves money

A cluster is an area where one type of manufacturing has concentrated for decades: raw materials, tooling, painting and packaging subcontractors, freight forwarders and customs brokers are all nearby.

Lower prices, driven by competition and short links between workshops.
Shorter lead times: components do not travel across the country.
Easier due diligence: neighbouring factories know everything about each other.
Five factory visits in one day, compared in person.

How to find your cluster

1Describe the product precisely, down to material and production method.
2Look at where the exhibitors of a relevant show are based: stand geography reveals clusters better than any directory.
3Check the exporting country’s customs statistics for your HS code — it points to the province.
4Cross-check the cluster map and pick the hub whose specialisation matches your product.

What to check before a factory visit

Registration documents and export licence: the English name must match the one on the invoice.
A real workshop address, not an office in a business centre. Ask for a video call from the floor.
Line load in your season: many factories peak before Chinese New Year and lead times double.
Minimum order and tooling cost if you need your own mould or die.

Combine the visit with a relevant trade show in the same region: one trip gives you both stand-by-stand comparison and live factory visits.
