The processing factory only processes on its behalf and collects processing fees, not with raw materials. If the big factory receives raw materials, it will have an impact. The price of raw materials is low and they are sold cheaply. The higher the price of raw materials, the higher the price. If only processing is carried out, the price will not be affected. For example, to make a bracelet, the cost of 500 will not change. Materials are not places for processing. There is no material fee, only processing fee.
