The Ministry of Science and Technology (MOST) is responsible for regulating the National technical regulation on gasoline, diesel fuels, and biofuels. QCVN: 1:2015/BKHCN regulates the limits for technical standards, quality, safety, health, and environmental protection of vehicle fuels. In addition, MOST is primarily responsible for managing, measuring, and controlling the quality of produced, imported, and circulated fuels in the market.

As of June 2022, MOST was in the process of developing technical regulations on gasoline, diesel fuel, and biofuels to comply with the Euro 5 fuel standards.

Availability of Euro 5 fuels

At the beginning of 2022, Petrolimex (Vietnam National Petroleum Group) began to offer Euro 5 complying fuel at some of their gasoline stations in three of the county’s major cities, Hanoi, Ho Chi Minh, and Da Nang. In the scope of the whole country, these offerings are still somewhat limited, and there are no regulations in place to mandate the offering of Euro 5 fuels.
