Finding

The G1 is made almost entirely in China, and its only US parts are export-controlled chips and cameras

The ring holds 19 supplier rows across 10 layers: seven in-house, three sole source, 17 China-supplied and four with the supplier not disclosed.

Coverage of Unitree's IPO prospectus says core parts are over 90% self-made and the supply chain over 90% domestic to China. Motors and joints are made in Hangzhou; reducers, bearings, chips, batteries and vision sensors are bought from Chinese vendors. The only US content is the NVIDIA Jetson Orin NX (EDU version) and the RealSense D435i depth camera, both sole-source parts that sit under US export controls. Livox, a DJI affiliate, supplies the lidar. Most named Chinese vendors come from A-share supplier lists and are labeled reported or inferred.
