The Indian government is preparing to halt the diversion of fresh sugarcane juice and B-heavy molasses for ethanol production ahead of the 2026–27 sugar season, moving to safeguard domestic food supplies after weather damage squeezed national sugar output. The impending directive, which the Ministry of Consumer Affairs, Food and Public Distribution is slated to notify shortly, prioritizes retail sugar inventory and price stabilization over biofuel quotas as opening stocks drop to decade-low thresholds.
Key takeaways
- Feedstock suspension: The central government plans to prohibit distilleries and sugar mills from utilizing primary sugarcane juice, sugar syrup, and intermediate B-heavy molasses for ethanol manufacturing during the upcoming supply cycle.
- Domestic stock buffer depleted: Net sugar output in the 2025–26 season fell to roughly 279 lakh tonnes after accounting for ethanol diversion, falling below the country’s normative annual consumption requirement of 280 to 285 lakh tonnes.
- Decade-low opening inventories: Factory carryover stocks at the start of the 2026–27 season (October 1, 2026) dwindled to 3.75 million metric tonnes—the lowest opening inventory recorded in more than ten years.
- Grain distilleries cushion E20 target: India’s ambitious 20% ethanol-blended petrol (E20) mandate will not be derailed by the curb, as grain-based feedstocks (chiefly maize and damaged foodgrains) now account for nearly 75% of total domestic ethanol output.
- Regulatory trade barriers persist: Alongside the domestic diversion halt, authorities are set to maintain the quantitative ban on commercial sugar exports while assessing whether to extend emergency duty-free raw sugar import windows.
Why the government is intervening in sugar-to-fuel channels
The central government’s move to pause sugarcane juice diversion for ethanol is a direct response to a tight supply-demand balance in the domestic sweetener market.
During the 2025–26 crop cycle, adverse weather patterns severely impaired cane production across India’s primary agricultural belts. Excessive monsoon rainfall and prolonged waterlogging in Maharashtra and northern Karnataka—which together account for more than half of India’s aggregate sugar output—combined with red rot outbreaks in Uttar Pradesh to depress cane yields and juice recovery rates.
Early industry forecasts published in late 2025 initially projected gross sugar output at 343 lakh tonnes. However, continuous crop degradation forced the Department of Food and Public Distribution (DFPD) to slash production estimates to approximately 306 lakh tonnes by August 2026.

[Annual Domestic Consumption: 280 – 285 Lakh Tonnes] ──► Deficit of 1 to 6 Lakh Tonnes
After accounting for roughly 27 lakh tonnes of sucrose diverted into the Ethanol Blended Petrol (EBP) programme, net domestic sugar availability contracted to 279 lakh tonnes. With domestic consumption holding steady between 280 and 285 lakh tonnes, factory gate reserves were drawn down aggressively. Opening inventories on October 1, 2026, slipped to 3.75 million tonnes, eliminating the multi-month inventory cushion that policymakers maintain to dampen festive price spikes.
Faced with retail sugar prices touching ₹56 per kilogram in urban retail markets during September, the government initiated defensive market interventions. It slashed the sugar stock-holding limits for wholesale dealers and traders from 4,000 quintals to 2,000 quintals through November 30, conducted physical warehouse audits, and allowed limited duty-free imports of raw sugar for port refiners. Halting juice and B-heavy molasses diversion represents the definitive lever to force every available kilogram of sucrose into edible white sugar crystal production.
The industrial mechanism: Sugarcane juice, B-heavy, and C-heavy molasses
To evaluate the operational impact of the decision, it is necessary to examine how sugar mills extract ethanol from different stages of the cane-crushing cycle.
When whole sugarcane is crushed in an industrial extraction mill, it produces raw sugarcane juice with high sucrose concentration. Under normal processing, this juice is boiled, evaporated, and crystallized in sequential stages to maximize crystal sugar output:

[Industrial Molasses for Distilleries]
1. Direct sugarcane juice and sugar syrup
Distilleries pump unclarified or concentrated cane juice directly into fermentation tanks, converting all fermentable sugars straight into hydrous ethanol without extracting any crystal sugar. While this generates the highest ethanol yield per tonne of cane and commands premium procurement prices from state-run Oil Marketing Companies (OMCs), it represents a 100% sacrifice of edible white sugar.
2. Intermediate B-heavy molasses
After the initial extraction of premium “A-grade” sugar crystals, the mother liquor is known as B-heavy molasses. This intermediate stream still contains roughly 45% to 50% fermentable sugars. If diverted to a distillery, mills forgo secondary and tertiary sugar crystallization stages, reducing factory sugar output by roughly 15% to 20% while producing high-grade ethanol.
3. Final C-heavy molasses
When mills extract every commercially recoverable grain of sucrose through three successive boiling cycles, they produce C-heavy molasses. This dense, viscous black residual byproduct contains only 30% to 35% non-crystallizable fermentable sugars. Processing C-heavy molasses produces less alcohol per quintal, but it causes zero loss of consumable white sugar.
By halting the diversion of direct cane juice and B-heavy molasses, the central government is restricting mills exclusively to C-heavy molasses. Every drop of juice entering factory intake gates must pass through the full crystallization train to bolster physical sugar production for grocery store shelves.
Shifting from cane to grain: The structural transition of India’s E20 program
The government’s willingness to clamp down on cane-based ethanol without compromising its target of 20% ethanol blending in petrol stems from a quiet structural transformation in feedstock origin.
Between 2018 and 2022, India’s ethanol program was almost entirely reliant on the sugar sector. Whenever monsoonal droughts struck cane-producing states, the blending program faced immediate supply shortages. Recognizing this systemic vulnerability, the Ministry of Petroleum and Natural Gas (MoPNG) and the DFPD orchestrated an aggressive diversification strategy toward non-food and grain-based feedstocks.
Official data indicates that the share of total domestic sugar diverted for fuel ethanol dropped from roughly 12% in the 2022–23 ethanol supply year to approximately 9% in 2025–26.
Concurrently, the manufacturing base underwent a massive technological pivot:
| Feedstock Category | Historical Output Share (2021–22) | Current Production Share (2025–26) | National Blending Role |
| Grain Feedstock (Maize) | ~0.0% | ~37.0% | Dominant high-growth feedstock |
| Damaged / Surplus Grains (Rice/Wheat) | ~18.0% | ~37.5% | Base load grain distillation |
| Sugarcane (Juice, B-Heavy, C-Molasses) | ~82.0% | ~25.5% | Restricted to non-food byproduct |
| Total National Ethanol Pool | 100% (Sub-10% Blend) | 100% (~20% National Average) | E20 Target Maintained |
Source: Compiled from Ministry of Petroleum and Natural Gas filings, DFPD operational reviews, and All India Distillers Association benchmarks.
Nearly three-fourths (74.5%) of the ethanol produced across India today originates from dedicated grain distilleries. The rapid adoption of dent maize (corn) has replaced sugarcane as the backbone of the biofuel supply chain, rising from zero contribution in 2021 to over 37% of national ethanol volumes.
Because public sector grain distilleries in Bihar, Punjab, Madhya Pradesh, and Andhra Pradesh are operating at expanded capacity, the suspension of cane juice diversion will not create an unmanageable fuel-blending deficit. State oil refiners can procure required ethanol volumes from grain processors while allowing the sugar industry to rebuild emergency food inventories.
Commercial impact on sugar mills and distilleries
While the policy shift achieves food-security objectives, it presents operational and financial hurdles for private and cooperative sugar mills.
Over the past five years, major integrated sugar manufacturers—including Balrampur Chini Mills, Dwarikesh Sugar Industries, Triveni Engineering, and Dalmia Bharat Sugar—invested thousands of crores of rupees into building multi-feed distillery capacities. Encouraged by government soft-loan interest subvention schemes, mills configured their plants to pivot dynamically between sugar production and ethanol fermentation based on prevailing market realizations.
The sudden regulatory closure of the juice and B-heavy routes disrupts these unit economics:
+-----------------------------------------------------------------------------------+
| FINANCIAL TRANSMISSION MATRIX |
| |
| [POLICY RESTRICTION] [OPERATIONAL SHIFT] [BALANCE SHEET IMPACT] |
| - Ban on Cane Juice Diversion ──► Maximized White Sugar - Higher working capital|
| - Ban on B-Heavy Diversion Crystallization blocked in inventory |
| - Depressed distillery |
| [PERMITTED CHANNEL] capacity utilization |
| - C-Heavy Molasses Only ──► Lower Alcohol Yields - Loss of high-margin |
| per tonne crushed cash flows from OMCs |
+-----------------------------------------------------------------------------------+
1. Liquidity and working capital cycles
Ethanol supply contracts with state-run OMCs (Indian Oil, BPCL, HPCL) provide sugar mills with rapid 21-day payment settlements, supplying cash to clear statutory Fair and Remunerative Price (FRP) dues to cane farmers on time. White crystal sugar, by contrast, is sold under monthly release quotas allocated by the central government. Forcing mills to convert all juice into crystal sugar bloats domestic warehouse inventories and blocks working capital, raising interest expenses for milling companies.
2. Stranded asset risk in standalone distilleries
Standalone distillery units that were expanded specifically to ferment pure cane syrup without crystal boiling houses face idle equipment, reduced operating leverage, and compressed return on capital employed (ROCE).
3. Industry demand for compensatory pricing
Industry bodies, led by the Indian Sugar and Bio-energy Manufacturers Association (ISMA), are expected to lobby the government for compensating policy adjustments. Specifically, millers are pushing for:
- An upward revision in the procurement price of C-heavy molasses ethanol to offset the loss of higher-margin B-heavy output.
- An increase in the Minimum Selling Price (MSP) of white sugar, which has remained legally fixed at ₹31 per kilogram since 2019 despite cane FRP increases mandated by the Cabinet.
Macroeconomic ripple effects: Food inflation vs. poultry feed competition
The decision to divert feedstock from fuel back into food illustrates the difficult policy trade-offs governing India’s agricultural economy.
Checking the retail food basket
Food inflation remains the primary volatile component within India’s Consumer Price Index (CPI), which rose to 4.82% in August. Sugar is an essential direct consumption staple and a critical raw material for processed food, confectionery, beverage, and dairy conglomerates.
Ahead of nationwide state assembly elections and the peak festive seasons of Navratri, Dussehra, and Diwali, the central government cannot afford a repeat of retail price spikes. Ensuring that domestic net production rebounds toward 310 to 320 lakh tonnes in the 2026–27 season is considered essential to keep retail sugar inflation anchored below 4%.
The unintended consequence: Maize price inflation
However, diverting the ethanol burden onto grains creates localized price friction in secondary agricultural markets.
Because grain distilleries are consuming unprecedented volumes of maize to supply ethanol, industrial demand has driven domestic maize prices above statutory Minimum Support Prices (MSP) across several producing states. This has sparked protests from the domestic poultry and livestock industries, where maize accounts for roughly 60% of total broiler and layer feed expenses.
Poultry associations have cautioned the Ministry of Agriculture that aggressive maize procurement by biofuel distilleries threatens to inflate farm-gate egg and broiler meat prices, effectively transferring inflationary pressures from the sugar basket into animal protein sectors.
Trade policy: Export bans and the import dilemma
The halt in domestic cane juice diversion will cement India’s absence from global sugar trade desks for another year.
India was historically the world’s second-largest sugar exporter, shipping over 11 million metric tonnes to global markets in 2021–22. However, following the production contraction, New Delhi imposed strict export restrictions in late 2023, subsequently renewing the ban through September 2026.
Given that opening domestic inventories of 3.75 million tonnes represent less than two months of national consumption, trade analysts confirm that commercial export quotas will remain frozen throughout the 2026–27 marketing cycle. India will service only nominal bilateral commitments to neighboring nations under diplomatic trade pacts (such as Maldives and Nepal) and restricted preferential tariff-rate quota shipments to the European Union and the United States.
Furthermore, if the initial weeks of autumn cane crushing show sub-par sucrose recovery, the Directorate General of Foreign Trade (DGFT) may be forced to allow additional tranches of concessional raw sugar imports for coastal refineries, reversing India’s multi-year status as an agricultural net exporter.
What could happen next
- Formal notification by DFPD: The Department of Food and Public Distribution is expected to issue the formal gazette order notifying the restrictions on sugarcane juice and B-heavy molasses ahead of peak crushing, detailing specific factory compliance guidelines.
- Review of OMC ethanol purchase prices: The Cabinet Committee on Economic Affairs (CCEA) will likely consider revising ethanol procurement prices for the 2026–27 Ethanol Supply Year, setting higher incentive tariffs for maize-based alcohol and C-heavy molasses.
- Monitoring autumn crushing yields: Agricultural commissioners across Uttar Pradesh, Maharashtra, and Karnataka will begin reporting field cane-cutting data in late October and November, determining whether improved post-monsoon sunshine has raised sucrose recovery rates above initial depressed projections.
Frequently asked questions
Why is the Indian government halting the use of sugarcane juice for ethanol?
The government is halting the diversion of sugarcane juice and B-heavy molasses to ensure all available sugarcane is utilized to manufacture consumable crystal sugar. Adverse weather and disease reduced net sugar production to 279 lakh tonnes in 2025–26, leaving opening stocks at a decade-low 3.75 million tonnes and threatening domestic supply and retail price stability.
Will this decision stop India from reaching its 20% ethanol blending target?
No. The 20% ethanol blending target (E20) will remain intact because grain-based feedstocks now generate nearly three-fourths of India’s total ethanol production. Distilleries running on maize and damaged foodgrains have expanded capacity, offsetting the reduction in cane-based ethanol.
What is the difference between B-heavy and C-heavy molasses?
B-heavy molasses is an intermediate product extracted after the first crystallization of sugar; it contains roughly 45% to 50% fermentable sugars, and diverting it reduces factory sugar yields. C-heavy molasses is the final, exhausted industrial byproduct left after all commercially recoverable sugar has been extracted; using it for ethanol produces no loss of edible white sugar.
How are private sugar mills affected by this ban?
Sugar mills that invested in modern distillery infrastructure will experience reduced operating leverage and lower sales of premium-priced ethanol. Forcing mills to produce only crystal sugar ties up operational liquidity in factory warehouses, requiring companies to borrow more working capital to service mandatory cane dues to farmers.
