# Bioethanol: Regulation

Mandates, safety rules and the monsoon risk India watches

What this tab covers How it is regulated and what could disrupt supply: hazard classification, rules in the EU, US and India, anti-dumping duties and other trade measures, and supply-risk notes.

#### Hazards

| Classification | UN number | Key risks |
|---|---|---|
| Flammable liquid category 2; eye irritation category 2 | UN1170 | Highly flammable with an invisible flame in daylight; vapours form explosive mixtures. Large storage tanks need foam systems rated for polar solvents. |

#### Main rules

| Where | Rule | Effect |
|---|---|---|
| **US** | Renewable Fuel Standard: 15 billion RINs of conventional biofuel in 2026 and 2027 (final rule, Apr 2026) | sets the base for maize ethanol demand |
| **US** | California LCFS and the 45Z clean fuel production credit | reward lower carbon intensity, e.g. carbon capture at ethanol plants |
| **Brazil** | RenovaBio decarbonisation credits (CBIOs) and the Fuel of the Future law raising the petrol blend to E30 (2025, indicative) | credits for low-CI producers; higher anhydrous demand |
| **EU** | RED III: 29% renewables in transport or 14.5% GHG intensity cut by 2030; crop-based biofuels capped at 7% of road and rail energy | limits crop ethanol growth; pushes residues and 2G |
| **Global** | CORSIA and ReFuelEU count alcohol-to-jet SAF | potential new demand for ethanol |

#### India

| Rule | Effect |
|---|---|
| **National Policy on Biofuels 2018 (amended 2022): E20 by ESY 2025-26** | reached in 2025; OMCs contract about 1,100 crore litres a year |
| **ESY 2026-27 tender (BPCL for the OMCs, 16 Oct 2026): no cane juice, sugar syrup or B-heavy molasses; sugar diversion set to zero** | shifts supply to maize, FCI rice, damaged grain and C-heavy molasses |
| **Central Motor Vehicles Rules amended to add E100 alongside E85 for flex-fuel vehicles (Oct 2026)** | legal basis for high-blend vehicles |
| **FCI sales of surplus rice to distilleries at a discount** | makes rice ethanol viable; 6.35 Mt in 2025-26 |

#### Trade measures

- India restricts imports of ethanol for fuel blending (indicative)
- EU import duty on undenatured and denatured ethanol (indicative)
- US 2025 tariff disputes with Brazil and India affect ethanol trade (indicative)

#### Supply risk

Production is concentrated in the US and Brazil, but feedstocks are diverse and plants are widely spread. India's main risk is the monsoon: a poor cane crop leads the government to shut sugar-based ethanol, as in Dec 2023 and Oct 2026.
