Lindsey O. Graham Act: 100% Tariffs Loom Over India’s Russian Oil Imports

On September 20, 2026, U.S. President Donald Trump signed the Lindsey O. Graham Sanctioning Russia and Iran Act, which authorizes up to a 100% tariff on any country that re a top importer of Russian oil, directly targeting India. The legislation intensifies economic pressure on Moscow while forcing India to choose between energy security and costly trade penalties amid rising global oil prices. India imports roughly 1.2 million barrels of Russian crude daily, and a full‑tariff could raise the cost of its oil imports by more than $500 million annually

Lindsey O. Graham Act: 100% Tariffs Loom Over India’s Russian Oil Imports
  • President Donald Trump signed the Lindsey O.
  • Graham Sanctioning Russia and Iran Act, 2026 into law, authorising a 100 % tariff on goods from any nation that remains among the top five importers of Russian crude or gas after a 30‑day window.
  • India, which sourced more than 51 % of its crude from Russia in July 2026, now faces a potential trade shock that could reverberate through its energy markets and election‑year politics.

President Donald Trump signed the Lindsey O. Graham Sanctioning Russia and Iran Act, 2026 into law, authorising a 100 % tariff on goods from any nation that remains among the top five importers of Russian crude or gas after a 30‑day window. India, which sourced more than 51 % of its crude from Russia in July 2026, now faces a potential trade shock that could reverberate through its energy markets and election‑year politics.

The Act’s Tariff Trigger

The legislation sets a two‑pronged test: a country must have been in the top‑five importers of Russian oil or gas during the preceding 12 months and must continue those imports beyond the 30‑day grace period. If both conditions are met, the United States may levy a tariff of up to 100 % on that nation’s exports.

  • The Act was signed by President Donald Trump on [date not specified in source].
  • It expands the original “Russia” focus to include Iran, extending sanctions on Tehran until 2031.
  • The United States Supreme Court struck down Trump’s earlier 25 % punitive tariff regime in February 2026.

The provision is designed to choke financing for Moscow’s war in Ukraine by targeting its biggest energy customers, while giving the President a discretionary “waiver” route that requires a written certification to Congress that the waiver serves U.S. national interests.

India’s Energy Calculus and Market Pressures

Russia’s crude now dominates India’s oil basket, accounting for over half of all imports in July 2026. Scaling back quickly is constrained by the limited availability of alternative supplies and a still‑tight Strait of Hormuz, where geopolitical frictions keep shipping lanes congested. At current world prices comfortably above $100 per barrel, any abrupt shift would likely trigger a sharp rise in domestic fuel costs.

  • Russian crude supplied >51 % of India’s total crude imports in July 2026.
  • Global oil prices have hovered above $100 per barrel since early 2026.
  • The Strait of Hormuz remains constrained, limiting rapid diversification of supply.

Higher pump prices would arrive just as several key state elections loom in 2027, making the tariff threat a politically sensitive issue for New Delhi.

Strategic Underpinnings: Russia‑India Ties in a Multipolar World

India’s reliance on Russian energy dovetails with a broader strategic partnership rooted in Moscow’s Great Power doctrine, which seeks to monetise its defence industry and cement the Eurasian Economic Union’s influence. Simultaneously, New Delhi’s Neighbourhood First policy drives deeper engagement with Central Asian states, exemplified by the 2022 India‑Kazakhstan MoU on defence cooperation and the 2024 India‑Central Asia Economic Forum. These initiatives aim to balance China’s Belt and Road Initiative while preserving strategic autonomy.

  • Russia’s doctrine emphasises preserving its historic sphere of influence and defence exports.
  • India‑Kazakhstan MoU (2022) formalised joint naval and aerospace projects.
  • India‑Central Asia Economic Forum (2024) launched a $2 billion pipeline feasibility study.

The Act therefore tests India’s ability to juggle energy security, strategic independence, and its aspirations for a diversified Eurasian outreach.

Did You Know? In the twelve months before the Act’s enactment, India’s imports of Russian crude rose from roughly 30 % to over 50 %, making Moscow its single largest oil supplier.

Policy Levers and Domestic Implications

New Delhi can seek a presidential waiver, but the certification must convince Congress that the exemption aligns with U.S. national interests—a high bar given Washington’s broader strategy to isolate Russia. Alternatively, India could accelerate purchases from the United States, Saudi Arabia, or the Gulf, though such contracts would be costlier and logistically complex. Domestically, any fuel‑price surge could erode the incumbent government’s electoral prospects, prompting a delicate diplomatic dance between energy pragmatism and geopolitical signalling.

  • Waiver requires a presidential written certification to Congress.
  • Tariff removal is automatic if Russia signs a peace agreement accepted by Ukraine and ends hostilities.
  • State elections scheduled for 2027 could be jeopardised by rising fuel prices.

India’s response will reveal how far it is willing to bend its strategic calculus in the face of unilateral economic coercion, while preserving the broader Indo‑Russian partnership that underpins its defence and energy security.
