United States President Donald Trump has signed a sweeping Russia sanctions law that expands Washington’s ability to target Moscow’s energy, defence and sanctions-evasion networks while giving the president substantial new tariff authority over major buyers of Russian oil and natural gas. The White House confirmed that Trump signed H.R. 5334, formally titled the Lindsey O. Graham Sanctioning Russia and Iran Act of 2026, on September 18 after the measure cleared both chambers of Congress. The legislation also extends existing sanctions relating to Iran, turning a measure debated for months in Washington into enforceable federal law.
The most consequential provision for India is the authority to impose tariffs as high as 100% on major importers of Russian energy, a category that potentially includes India and China. The law does not mean a 100% tariff has automatically been imposed on Indian products on September 19, and the administration retains substantial discretion over implementation, exemptions and the precise rate applied. New Delhi has nevertheless already warned Washington that using the new powers against India could damage bilateral relations and disrupt international energy markets.
What did Donald Trump actually sign into law on September 18?
The legislation targets several channels through which Congress believes Russia continues financing its war against Ukraine. Measures cover Russian political and military figures, parts of the energy and defence sectors, financial networks and the so-called shadow fleet of tankers used to transport Russian oil outside conventional Western shipping and sanctions systems. The law also codifies and expands sanctions authorities that had previously depended more heavily on executive action.
Its tariff provisions are particularly unusual because they use access to the enormous US consumer market as leverage against third countries rather than targeting Russia alone. Congressional language focuses on major buyers of Russian crude oil or natural gas and countries facilitating sanctions evasion, while providing exceptions and presidential waiver mechanisms under specified circumstances. The policy is designed to force large energy customers to weigh the benefits of Russian supplies against the potential cost of selling their own goods into the United States.
Does the law automatically place a 100% tariff on Indian exports to the United States?
It does not automatically mean every Indian product is now subject to a 100% duty. The legislation creates tariff authority reaching as high as 100% for countries meeting defined Russian-energy criteria, while implementation requires determinations under the law and allows the administration substantial discretion. Any headline stating that the United States has already imposed a blanket 100% tariff on India would therefore get ahead of the confirmed policy position.
India is nevertheless clearly exposed because it has become one of the largest purchasers of Russian crude since Western sanctions changed global energy flows after 2022. Reuters reported that Russia accounted for a substantial share of Indian crude imports, while the United States remains India’s largest export destination, with Indian goods exports to the US reaching $42.79 billion between April and August. That combination means New Delhi has meaningful economic exposure on both sides of the dispute.
How has India responded to Washington’s new Russia sanctions powers?
India’s Ministry of External Affairs has said the government remains firmly committed to ensuring energy security for 1.4 billion people and will continue sourcing supplies according to market conditions and national requirements. New Delhi also said it had explained to US officials that tariff measures connected with Russian oil could have implications for the wider bilateral relationship and international energy markets. The government said it would take necessary steps to protect India’s trade and economic interests.
That response reflects the difficult economics confronting India. Reducing Russian crude purchases rapidly could force refiners toward more expensive alternatives at a time when global energy markets are already disrupted by conflict involving Iran, Saudi infrastructure and important shipping routes. Continuing large Russian purchases, however, could expose Indian exporters to a new US tariff instrument potentially more damaging than the savings achieved through discounted crude.
Why could implementing the sanctions law push global oil prices higher?
Russia remains one of the world’s largest petroleum exporters, which means measures that remove significant Russian barrels from normal markets can tighten global supply even when the political objective is to reduce Moscow’s revenue. Russian ESPO crude climbed above $120 a barrel during September as Chinese refiners competed for supply amid Middle Eastern disruption, demonstrating how geopolitical restrictions can sometimes increase the value of barrels that continue reaching buyers.
The economic outcome will depend heavily on whether Washington uses tariff threats to change purchasing behaviour without actually removing enormous volumes from the market. If India and China sharply reduce Russian buying but alternative purchasers cannot absorb the oil, Russian revenue could decline as intended. If supply constraints simultaneously push world prices materially higher, Russia could partially offset lower volumes through higher prices on remaining exports, creating a difficult policy balance for Washington.
Why does the law also matter for US presidential tariff powers?
Congressional debate was unusually intense because the measure gives the president explicit statutory tariff authority after earlier legal battles questioned the extent to which a president can impose large trade duties using general emergency powers. Some lawmakers who supported stronger sanctions against Moscow were nevertheless concerned about handing the executive branch a new instrument that could affect major US trading partners.
That concern extends beyond the current Russia dispute because statutory authorities can survive the immediate political moment for which they were created. The legislation includes procedural provisions and waivers, but the underlying precedent is significant: Congress has explicitly connected sanctions policy with potentially enormous tariffs against third countries. Future administrations could therefore inherit an unusually powerful trade tool even if the Ukraine war eventually ends.
What happens next for India, China and other major Russian energy buyers?
The immediate question is how quickly Trump chooses to use the new powers. The law gives Washington leverage before a tariff is actually collected because governments and companies may begin adjusting purchases simply to reduce the risk of being targeted. India is likely to pursue negotiations around exemptions, implementation criteria or a gradual reduction mechanism rather than abruptly abandoning Russian crude while global supplies remain tight.
Russia has responded by arguing that additional American sanctions will make diplomatic efforts to end the Ukraine war more difficult, while US supporters of the law say stronger economic pressure is necessary precisely because earlier measures failed to force Moscow to change course. Those are competing policy assessments whose effectiveness cannot yet be determined. What changed on September 18 is much more concrete: Trump now possesses statutory powers Congress spent months debating, and India’s Russian oil purchases have moved from a recurring diplomatic disagreement into a potentially direct US tariff risk.
What are the key takeaways from Trump signing the Russia sanctions law?
The Lindsey O. Graham Sanctioning Russia and Iran Act is now law rather than proposed legislation, but India has not automatically been hit with a 100% US tariff. The measure expands sanctions against Russia and authorises powerful tariff measures against major Russian energy buyers, while presidential decisions, legal criteria and possible exemptions will determine how aggressively those authorities are applied.
For India, that distinction provides time but not certainty. New Delhi must protect affordable energy supplies while preserving access to its largest export market, and Washington must decide whether imposing extreme tariffs on major economies advances its Russia strategy without generating another inflationary trade shock. The next phase therefore moves from Congress to executive implementation, where the economic consequences could become substantially larger than the legislative debate itself.
