Data Source & Methodology

Our dataset maps manufacturing regions in China using public industry-belt research, official cluster designations, and cross-checked trade-market information.

How we build the map

We start with public research on China's industry belts and major B2B category structures, then cross-check cities against government cluster lists and verified market sources. Each region is tagged with sourcing-relevant capabilities rather than generic descriptions.

Accuracy & updates

Industry landscapes change. The map is intended as a starting point for sourcing research, not a guarantee of current supplier availability. If you spot outdated information or a missing region, let us know.
