How to buy second-hand Apple phones in bulk in the United States, and whether to make old phones?

Generally speaking, these goods are in the hands of electronic environmental recyclers with environmental protection qualifications. Regular companies can only sell obsolete products to environmentalists, and then these environmentalists sell obsolete equipment. The industry as a whole is gray and not very transparent, which is difficult for laymen to reach. At present, the origin of these commodities is mainly the United States, Japan and other electronic products developed countries, and they are generally sold to Hong Kong, Dubai and other places, and then transferred through these free trade ports and sold all over the world. At one time, the largest purchase volume of these products came from Huaqiang North, China, but with the decline of Huaqiang North, the purchase volume of Huaqiang North is gradually decreasing, and these eliminated equipment are directly sold to underdeveloped areas, such as India. If the subject wants to buy directly in the United States, there are actually many problems in operation, such as foreign exchange control and transaction security. You'd better have local people to help you participate in the transaction. Generally, mainland merchants purchase in the United States through China intermediaries, but for the sake of capital security, it is suggested to purchase in Hong Kong first, and then consider purchasing directly in the United States. Hong Kong trading companies also bid in the United States directly on behalf of customers, with a commission of around 3%. Of course, you can also ask American environmental recyclers for a product list and make a quotation by mail, but generally large companies adopt on-site bidding and quotation, so it is unrealistic for you to purchase remotely.
