Under the new quotas, 1 million tonnes of LSFO can be exported while 1.579 million tonnes of refined fuels can be shipped, according to the source and the document issued by the Ministry of Commerce.
The new issue brings this year's total permits for refined fuel exports to about 38.6 million tonnes, down one-third from last year's quotas.
The document did not break down the specific products allowed to be exported under the refined fuel quotas, which normally cover diesel, gasoline and jet fuel.
The new LSFO quotas raise the total allowances for LSFO to 12 million tonnes for 2021, up from 10 million tonnes last year.
The refined fuel quotas were issued to state-run China National Petroleum Corp (CNPC), China Petroleum & Chemical Corp (Sinopec) and Sinochem Group, as well as private refiner Zhejiang Petrochemical Corp, the document shows.
The LSFO quotas were allotted to CNPC, Sinopec and CNOOC.
China's Ministry of Commerce did not immediately respond to a request for comment.
