Vietnam E10 Biofuel Roadmap: State Price Control from June 2026, PLX Impact

Overview

The Ministry of Justice is reviewing a draft resolution on the roadmap for using E10 biofuel, which will classify E10RON95-III as a common consumer good from June 1, 2026, with state-set base prices replacing RON95 mineral gasoline. This regulatory change directly affects Petrolimex (PLX), Vietnam’s largest petroleum distributor, and other fuel traders.

Key Facts

• The draft resolution, drafted by the Ministry of Industry and Trade, is under review by the Ministry of Justice.
• From June 1, 2026, E10RON95-III will be classified as a common consumer good, with state-set base prices replacing RON95 mineral gasoline (level III).
• The Ministry of Industry and Trade and the Ministry of Finance will jointly announce base prices for E10RON95-III and E5RON92.
• The base price formula includes global gasoline prices (average between two pricing periods), ethanol fuel costs, import premiums, and domestic refinery costs.
• Traders must ensure quality compliance with national technical regulations and may outsource testing to qualified units.
• In the June 4 pricing period, only E5RON92, diesel, and mazut were state-priced; E10RON95 prices were self-declared by traders (e.g., Petrolimex set E10RON95-III at 22,330 VND/liter).
• PLX closed at 41,850 VND on June 4, 2026, up 6.90% with volume of 6,418,000 shares.

What Happened

The Ministry of Justice is reviewing a draft resolution that sets the roadmap for E10 biofuel usage in Vietnam. The key provision is that from June 1, 2026, E10RON95-III will be reclassified as a common consumer good, meaning its base price will be set by the state, replacing the current mineral gasoline RON95 (level III). The Ministry of Industry and Trade and the Ministry of Finance will jointly determine and announce the base price, incorporating global gasoline prices, ethanol costs, and other logistics premiums.

Currently, E10RON95 prices are self-declared by traders. For example, on June 4, Petrolimex set E10RON95-III at 22,330 VND/liter, while the state only announced prices for E5RON92, diesel, and mazut. The draft also mandates quality assurance responsibilities for traders and allows them to outsource testing to accredited labs.

Market Context

PLX shares rose 6.90% to 41,850 VND on June 4, 2026, with heavy volume of 6.4 million shares, indicating strong market interest. The stock trades on HOSE and is a bellwether for the energy sector. The regulatory shift toward E10 aligns with the government’s long-term biofuel promotion policy, but the transition to state pricing could compress margins for distributors like PLX if cost pass-through is limited.

Strategic Significance

For PLX, the mandatory switch to E10RON95-III as a state-priced good reduces pricing flexibility and may squeeze margins if ethanol costs rise. However, PLX’s dominant market position and existing infrastructure for biofuel blending could provide a competitive advantage. The policy also supports Vietnam’s environmental goals and reduces dependence on imported mineral gasoline. Long-term investors should monitor the final pricing formula and PLX’s ability to manage ethanol supply costs.

What to Watch

• Final approval of the draft resolution by the Ministry of Justice and the government.
• Details of the base price formula for E10RON95-III, especially the ethanol cost component.
• PLX’s Q2 2026 earnings report for margin impact from the transition.
• Any adjustments to the June 1, 2026 timeline or scope of products affected.
• Competitor responses and market share shifts among fuel traders.
