According to the Ministry of Industry and Trade, the State has not yet announced the price of E10 bio-gasoline. Businesses are calculating selling prices themselves according to business costs of businesses.
To put E10 into circulation from June 1, 2026 and promptly announce the base price for businesses to implement in the transitional context, special regulations are needed.
When bio-gasoline is widely consumed in the market, management agencies will identify popular consumer goods and have sufficient data to determine the factors constituting the base price.
In the immediate future, the item E10 RON 95-III is identified to implement the announcement of the base price. After 3 months of implementation, when the popular consumer biofuel item is identified, the Ministry of Industry and Trade will announce the base price of this item.
