Bloomberg reported over the weekend that India is considering raising import duties on edible oils to support domestic farmers and shore up the weakening rupee. If confirmed, this would reverse the May 2025 cut that slashed crude edible oil duties from 27.5% to 16.5%. India imports roughly 16 million metric tonnes of edible oil annually — making this one of the largest single import categories after crude petroleum. For investors, the question is simple: who wins?

We dug into filings from the companies most directly exposed to this policy shift. Here are five names with the strongest evidence in their favour.

1. AWL Agri Business (Adani Wilmar) — India’s Largest Edible Oil Importer Turns Protectionist Winner

AWL handles roughly 20% of India’s total edible oil imports, per its FY24 annual report. That might sound like a duty hike would hurt them, but the opposite is true. AWL’s Mundra plant is the largest single-location refinery in India at 5,000 MT/day capacity, and the company runs 23 manufacturing plants nationwide.

The key mechanism: when duties on crude oils rise but refined oil duties stay at 35.75%, the gap between crude and refined import duties widens. This protects domestic refiners like AWL, who import crude oil cheaply and sell refined, branded products at a premium. Per their Q2 FY26 investor presentation, the previous duty hike in September 2024 widened this differential from roughly 8% to 19% — a massive competitive moat for domestic refining.

AWL’s edible oil segment ROCE jumped from 13% in FY24 to 23% in FY25, per their Q4 FY25 earnings presentation, as the September 2024 duty hike flowed through. Revenue in Q2 FY26 hit INR 17,126 crores, up 22% year-on-year. A fresh duty increase could repeat this playbook.

2. Patanjali Foods — Domestic Oil Palm Plantation Is the Hidden Asset

Most investors think of Patanjali Foods as a branded FMCG play, but its oil palm plantation business is where the duty story really shines. Per their Q1 FY26 investor presentation, the oil palm segment delivered revenue of INR 599 crores at a 24.16% EBITDA margin — far richer than the 1.78% margin on the edible oil trading segment.

The company has 92,133 hectares of oil palm plantations across India with partnerships involving 66,000 farmers and MoUs with 12 state governments. When import duties rise, domestic crude palm oil prices strengthen, directly boosting plantation realizations.

On the branded side, Patanjali’s edible oil segment generated INR 13,654 crores in revenue in H1 FY26 with 21% year-on-year growth. Branded sales now account for 72% of total edible oil revenue, giving the company pricing power that unbranded importers lack. Their branded mustard oil and sunflower oil lines registered double-digit sequential growth in Q1 FY26.

3. Godrej Agrovet — India’s Largest Domestic Palm Oil Producer

Godrej Agrovet is India’s largest producer of crude palm oil (CPO) and palm kernel oil (PKO). Per their Q2 FY25 investor presentation, CPO realizations reached INR 92,562 per metric tonne, up 18.1% year-on-year. PKO realizations surged 43%.

The September 2024 duty hike — when basic customs duty on crude oils went from 0% to 20% — was a direct tailwind. In their May 2025 earnings call, management noted that their new refinery for crude palm oil has already added approximately 1.25% to overall profitability, with a palm kernel oil refinery under construction expected to add another 1% to 1.2%. A third phase involving hydrogenation and interesterification could add an additional 1-2%.

The company’s annual report for FY25 described the oil palm business as a "standout performer" with revenue and margin growth fuelled by higher CPO and PKO realizations of 32% and 43% respectively. Another duty hike would extend this runway.

4. Kaveri Seed — The Oilseed Play Nobody’s Watching

When edible oil import duties rise, so does demand for domestically grown oilseeds. Kaveri Seed Company, primarily known for hybrid corn and rice seeds, has been quietly building its sunflower and mustard seed portfolios.

Per their Q3 FY26 investor presentation, sunflower seed volumes surged 94% year-on-year and mustard seed volumes jumped 64%. Sunflower acreage across Indian states increased 9.3% during the quarter. Management specifically noted that "this year mustard product performance looks good so we are expecting good growth in coming years too."

India’s government has been pushing the National Mission on Edible Oils (NMEO-OP) to reduce import dependence, and higher duties make domestic oilseed farming more economically attractive. Kaveri, with its seed technology and farmer distribution, sits at the top of this supply chain. Nine-month FY23 revenue reached INR 940 crores with a PAT margin above 29%.

5. Marico — Saffola Benefits, But Watch the Vegetable Oil Squeeze

Marico is a two-sided story. Its Saffola edible oil franchise benefits from any policy that supports domestic pricing power. But its broader FMCG portfolio faces vegetable oil cost pressures.

Per Marico’s FY25 annual report, the India business delivered INR 8,110 crores in turnover with 14% year-on-year growth, though operating margins moderated from 22.4% to 20.2% due to elevated copra and vegetable oil prices. In the most recent earnings call from May 2026, management noted copra prices have corrected approximately 35% from peak levels, but "vegetable oils and other crude-linked inputs continue to exhibit an upward bias driven by ongoing geopolitical tensions in the Middle East."

After the September 2024 duty hike, Marico took a 15% price increase in Saffola. The company targets INR 20,000 crores in consolidated revenue by FY30 with mid-teen EBITDA growth. A fresh duty hike would temporarily compress margins but Marico has demonstrated it can pass through costs — the key question is speed.

What Retail Investors Should Do

A duty hike on edible oils is not confirmed yet, but Bloomberg’s report suggests the government is actively considering it. The playbook from September 2024 is clear: domestic refiners and oil palm growers benefited most, while pure-play importers and FMCG companies dependent on cheap imported oils faced short-term margin pressure.

If you want to position ahead of this policy shift, the strongest filing evidence points toward companies with domestic production capacity — particularly AWL’s refining advantage, Patanjali’s oil palm plantations, and Godrej Agrovet’s status as India’s largest CPO producer. Kaveri Seed offers a less obvious way to play the theme through oilseed supply. Be cautious with packaged food companies like Prataap Snacks, which reported in its Q3 FY26 presentation that palm oil cost increases already pressured gross margins by 150 basis points quarter-on-quarter.

Remember: duty policy can shift quickly in both directions. The May 2025 cut reversed the September 2024 hike within months. Size positions accordingly and watch for the official government announcement.
