Processing enterprises are generally divided into two types: feed processing enterprises and processing enterprises with supplied materials. Feed processing means that enterprises import some or all raw materials, auxiliary materials, spare parts and packaging materials by themselves, and then process them into finished products at home and sell them abroad. Processing with supplied materials is well understood, which means that enterprises rely on one or some enterprises to take materials from relying enterprises and engage in processing procedures specifically for relying on enterprises. The difference between feed processing and material processing: in feed processing business, imported raw materials occupy enterprise funds and foreign exchange, and the ownership of goods belongs to enterprises. There is no close internal relationship between import and export (suppliers of raw materials and buyers of finished products are generally irrelevant), and enterprises bear the price and sales risks themselves.
