China's manufacturing is organized in clusters. One city or county often makes a large share of one product, from valves to toys to laser cutting machines. Knowing where a product is really made helps you in three ways. You can tell when a supplier is far from the cluster and probably buying in. You know which checks matter for that industry. And you can plan a factory visit that covers several suppliers in one trip.
The table below lists the main regions by product, the most common risk I see for buyers in each, and the guide with the checks for that region. It covers the industries my clients ask about most: machinery, industrial and electrical equipment, and the main consumer goods hubs.

What a cluster tells you about a supplier
When a supplier says it is a factory, check where it is. A valve "factory" with an office in Shanghai and no address in Wenzhou or another valve area is probably buying from a valve cluster. That is not wrong, but the price, lead time and responsibility are different, and you should know.
The same works the other way. A supplier located in the right cluster is not automatically a factory. Clusters are full of trading companies too, because buyers come there. The registration, the insured headcount and a live video walk-through tell you which kind of company you are dealing with.
The checks that work everywhere
Whatever the region, the first checks are the same: the official registration and business scope, the insured headcount, court records, the name on the bank account, and a live walk-through that you direct. The full list is in how to verify a Chinese supplier: 12 checks before you pay. The regional guides add the checks that matter for each industry.
Planning a visit across several suppliers
Many buyers shortlist suppliers in different provinces. A good order is to run a remote verification on all of them first, then visit only the two or three that pass, grouped by region. I am based in Xi'an and travel by high-speed train to most manufacturing regions, so visits in the same cluster can be combined to save travel costs.
Ask me about a region or a supplier
If your product or region is not in this list, send me the supplier's name. I check suppliers anywhere in mainland China.
