This seems unlikely right now. Most major manufacturers of bicycles are in Taiwan and China (all brands around the world use them), but this is for bicycles built for a single person. Most of the frames are carbon fiber, a mold is built for various sizes and is used 1000's of times. For some reason cargo bikes are a different story and welded together from steel or aluminum (there might be a few carbon fiber ones, but I assume cost of r&d/manufacturing to be prohibitive to be competitive with metal for small lots). Alibaba has lots of generic bicycle frames but no cargo bikes.
