Nationwide Distribution of New Gasoline Variant Set to Begin June 1, 2026, Sealing the Fate of RON92

According to Circular No. 50/2025/TT-BCT recently issued by the Ministry of Industry and Trade, Vietnam has officially announced its roadmap for implementing the blending ratio of biofuel with traditional gasoline. The most significant highlight is that E10 gasoline—a biofuel blend containing 10% ethanol mixed with mineral gasoline—will be mandated for nationwide distribution and sale starting from June 1, 2026.

This decision marks a major step forward in the government’s efforts to reduce greenhouse gas emissions, protect the environment, and transition toward a more sustainable energy source.

Under the same Circular, the production and use of E5 RON92 gasoline will continue until December 31, 2030.

For biodiesel, the Ministry has not yet mandated the blending ratios of B5 or B10 but encourages businesses and individuals to engage in the production and trade of these products.

The Circular clearly defines its scope of application, targeting gasoline traders; organizations and individuals involved in the production, import, blending, formulation, and trade of biofuels and bio-gasoline; as well as relevant agencies and organizations. These regulations do not apply to the blending of biodiesel for diesel engines or fuels used in aviation and maritime operations by security and defense forces.

The Circular stipulates that during implementation, based on socio-economic conditions, technology, supply-demand dynamics, and pricing, the Minister of Industry and Trade may adjust blending ratios or introduce new gasoline types to ensure energy security, environmental protection, and consumer rights.

The Ministry of Industry and Trade has tasked the Domestic Market Management and Development Department with collaborating with the Ministry of Finance to develop and propose tax policies, fees, and financial incentives to promote the trade and use of bio-gasoline and biofuels. They will also provide guidance on pricing methods, ensuring market principles with state oversight.

What is E10 Gasoline?

E10 gasoline is a finished product blended from mineral gasoline derived from fossil fuels and biofuels, with a specific ratio of fuel alcohol. According to QCVN 01:2022/BKHCN standards for gasoline, diesel, and biofuels, E10 gasoline is a biofuel with a fuel alcohol content of 9–10% by volume.

Domestic and international studies show that ethanol has a high oxygen content, enhancing the combustion process of fuel mixtures. As a result, E10 gasoline can reduce Carbon Monoxide (CO) and Hydrocarbon (HC) emissions by up to 20% compared to traditional mineral gasoline. Reduced emissions mean lower air pollution risks and a decrease in the greenhouse effect—a primary driver of global climate change.

Currently, over 60 countries widely use E10 gasoline, and many regions, including the U.S. and Europe, have enacted laws mandating the use of blended fuels combining gasoline with pure biofuels.

Regarding supply, Vietnam has six ethanol (E100) production plants with a total design capacity of approximately 600,000 m³ annually, meeting about 40% of E10 blending demand. The remaining shortfall can be supplemented through imports from major producers like the U.S. and Brazil. The Ministry of Industry and Trade confirms that key enterprises such as Petrolimex, PVOIL, and BSR possess sufficient blending infrastructure to meet demand.
