Taiwan: Biofuels Report 2026

Taiwan's ethanol-blended gasoline program is limited to a small-scale E3 pilot. The government is reviewing new standards that could allow E10, but biofuels remain marginal due to limited policy support, high tariffs, and challenges such as required fueling station upgrades, vehicle compatibility, and low consumer acceptance. Most ethanol is imported and subject to a 20 percent tariff, with the United States a minor supplier. The government's focus on electrification means biofuels are only a complementary measure for decarbonizing the existing fleet. Biodiesel use is minimal after the blending mandate ended in 2014, and nearly all production is exported. Sustainable aviation fuel (SAF) is gaining attention, but progress is slow due to feedstock constraints and lack of mandates. If Taiwan aligns its standards and expands ethanol blending, new market opportunities could emerge for U.S. exporters.
