E10 biofuel has already been piloted in Hanoi, HCM City and Hai Phong since August 1 this year.

Vietnam plans to roll out E10 biofuel nationwide from June
2026 under a new circular issued by the Ministry of Industry and Trade (MoIT).

Under Circular 50/2025/TT-BCT from the MoIT,  all unleaded gasoline on the
market must be converted to E10—a blend containing 10% ethanol—from June 1, 2026. However, the existing E5 RON92, which contains 5% ethanol, will remain available through
the end of 2030.

The MoIT was quoted by the Vietnam News Agency as stating that it may adjust blending ratios and introduce
new gasoline products when necessary to ensure energy security, meet
environmental targets, and safeguard consumer interests.

The ministry also noted that the use of biodiesel B5 and B10 will
not be mandatory for diesel engines at this stage.

E10 biofuel has already been piloted by major distributors
Petrolimex and PV Oil since August 1 in Ho Chi Minh City, Hanoi and Hai Phong.
