Guatemala’s E10 rollout opens a new market for US ethanol suppliers
Guatemala began selling regular gasoline containing 10% ethanol on August 22, 2026, creating new demand for domestic and imported biofuel. US corn producers see room to expand maritime shipments, while Guatemala estimates it will need 22.98 million gallons of ethanol during 2026.
E10 sales begin after supply-chain preparations
Guatemala began selling regular gasoline blended with 10% ethanol, known as E10, on August 22, 2026. The launch followed a technical operating phase for the supply chain from June 30 through August 21. The Ministry of Energy and Mines, or MEM, said distribution would proceed gradually and estimated that the blend would reach service stations nationwide in about five days.
The mandate creates an immediate requirement for both locally produced and imported ethanol. MEM estimates that Guatemala will need about 22.98 million gallons during 2026 to supply the regular-gasoline market with E10. As of August 18, approximately 7.41 million gallons were available, while a sixth vessel was being unloaded at Puerto Santo Tomás de Castilla. Prensa Libre reported that the country had already received its first ethanol cargoes.
US corn industry targets additional shipments
Representatives of the Iowa Corn Association view the launch as an opportunity for US ethanol producers. Board member Stu Swanson said the large production base in the US Midwest could meet growth in Guatemalan demand. He did not provide details about the logistics used for the initial cargoes, but identified maritime transport as the natural option for supplying Guatemala. Canada remains an easier destination because of its proximity and blending mandates, while deliveries to Guatemala would mainly require ocean freight.
The prospective ethanol trade builds on an established agricultural relationship. According to data cited by the US Grains and BioProducts Council, Guatemala ranked among the ten largest export markets for US corn by volume between 2024 and 2025. The United States shipped 1,871,924 metric tonnes of corn worth about US$380.9 million, while grain products in different forms totaled 2,298,497 metric tonnes valued at approximately US$862 million. Swanson said US and Guatemalan authorities have discussed continued ethanol supplies, although no future shipment volumes were disclosed.
Imports and domestic production could coexist
Guatemala plans to cover E10 demand with a combination of domestic output and imports. Local ethanol is produced from sugar cane, while most US ethanol is made from corn. Swanson said US suppliers aim to supplement an expanding market rather than displace existing Guatemalan production. The balance will depend on delivered import costs, the ability of domestic plants to supply fuel-grade ethanol and the pace at which consumption increases under the new blend.
Price effects remain uncertain. Swanson said that in the United States, moving from E10 to E15 can produce a difference of about US$0.10 to US$0.15 per gallon, with larger savings possible near Midwestern ethanol plants because transport costs are lower. Those figures do not imply an equivalent reduction in Guatemala. Energy and Mines Minister Erwin Barrios has estimated that adding 10% ethanol could reduce Guatemalan pump prices by Q0.50 to Q1.50 per gallon, partly because the ethanol share is not subject to the country’s petroleum distribution tax. For US producers, the rollout adds a potential outlet in Central America; for Guatemalan fuel suppliers, it introduces a recurring procurement need tied to blending volumes, shipping logistics and domestic availability.
