Secondly, the import of refined oil needs to pay foreign exchange. In the management regulations of SAFE, it is clearly restricted that private capital can settle foreign exchange. It is impossible to open a letter of credit for exporters only by purchasing foreign exchange. The foreign exchange quota is mainly state-owned enterprises and central enterprises.
Then even if a letter of credit can be issued, there will still be a problem, such as the exporter's export ability and the credit status of the shipping company. Some exporters can't supply stably, which will lead to the interruption of supply chain, and some shipping companies sell three goods halfway.
Moreover, the refined oil is different from other commodities, and it is clearly controlled when entering China Customs, so the corresponding deployment units need to make production and sales plans for customs declaration.
Finally, after the import of refined oil, there are two problems: storage management and sales. Transportation from domestic terminals to the surrounding areas is short-distance and will be relatively high. If the sales are delayed, the corresponding management expenses will be a lot of money.
