Trump Now Holds a 100% Tariff Weapon Against China and India—but Will He Dare Use It Before the Midterms?
Congress has sent Trump a sanctions bill allowing tariffs of up to 100% on major buyers of Russian energy. The authority is sweeping, but its use remains optional.
The U.S. Congress has handed Donald Trump an economic weapon powerful enough to disrupt trade with China and India: authority to impose tariffs of up to 100% on major buyers of Russian oil and gas.
The House passed the Lindsey O. Graham Sanctioning Russia and Iran Act of 2026 by 262 votes to 159 after the Senate approved it 86–11 in August. The legislation now goes to Trump, who is expected to sign it.
The bill targets Russian banks, senior officials, defense and energy networks and the shadow fleet used to move sanctioned oil. It also extends the Iran Sanctions Act and gives the president power to penalize the five largest purchasers of Russian energy. China and India sit at the center of that category.
The crucial word is “may.” The tariffs are authorized, not automatically activated. The president can use waivers, judge whether countries are reducing purchases and choose timing. Congress has created leverage rather than a mandatory trade wall.
That discretion explains both the bill’s appeal and the opposition. Supporters believe Trump can threaten devastating market access costs to force Russian customers to change behavior. Critics fear the president can apply exceptions selectively, punish rivals, reward partners or leave the strongest provisions unused.
China presents the largest strategic dilemma. Trump is scheduled to meet Xi Jinping on September 24 and has recently emphasized Chinese cooperation on Iran. Imposing a 100% tariff days before or after that meeting could destroy the diplomatic agenda and provoke retaliation across technology, agriculture and rare earths.
India is also difficult to coerce. New Delhi says it buys energy according to price and the needs of 1.4 billion citizens. It views Russian crude as an energy-security choice and has already objected to American tariffs as unfair. Heavy new duties could push India closer to Russia or China even as Washington wants it as an Indo-Pacific partner.
The oil-market effect may be opposite to the political goal. If tariffs force significant Russian barrels off the market rather than redirecting them through intermediaries, crude and diesel prices could rise. With the U.S. midterm elections only weeks away, voters may blame the administration for fuel inflation before sanctions weaken Moscow.
Russia has spent years building alternative shipping, insurance and payment routes. Sanctions can raise costs, reduce margins and make transactions riskier without eliminating exports. A tariff on importing countries attacks demand more directly, but it also taxes American buyers of those countries’ goods.
The legislation carries the political legacy of Senator Lindsey Graham, who pushed the proposal for more than a year before his death in July. Naming the act after him adds moral and partisan pressure on Trump to use it. Yet Graham’s absence also removes one of the most persistent advocates who might have publicly demanded enforcement.
Tariff design will determine the damage. A 100% duty applied broadly to all imports from a targeted country would be far more disruptive than a product-specific measure. The legislation gives executive agencies room to define scope, exemptions and evidence that a country is reducing Russian purchases.
Companies may reroute goods through third countries, just as oil is blended or re-labeled through trading hubs. Enforcement would require customs tracing, beneficial-ownership data and coordination with allies—otherwise compliant businesses could suffer while sophisticated networks adapt.
Ukraine welcomed the vote as a demonstration that Congress remains committed to applying pressure on Vladimir Putin. Many Democrats still opposed the final version because they believed it transferred too much tariff authority to Trump and contained broad waiver powers.
The Iran extension helped secure presidential support and links two sanctions theaters that have different economic dynamics. That combination may complicate diplomacy if Washington wants Chinese help with Tehran while threatening Beijing over Russian oil.
The bill’s greatest immediate power may be psychological. Chinese and Indian refiners, banks and exporters must now price the risk that access to the U.S. market could change by presidential decision. Even an unused weapon can alter contracts.
What to watch next
Will Trump sign immediately and issue implementation guidance? Does he threaten China before the Xi meeting or keep the weapon holstered? Can India win a waiver by reducing purchases? And will Congress’s strongest Russia sanctions tool squeeze Moscow—or raise American prices so sharply that electoral politics prevents its use?
