Trump Signs Sweeping Russia‑Iran Sanctions Bill, Raising the Specter of 100% Tariffs on India and China

On September 19, 2026, President Donald Trump put his signature on the Lindsey Graham Sanctioning Russia and Iran Act of 2026, turning a hard‑won piece of legislation into law. The bill isn’t just another line on the statute books; it actually hands the U.S. administration the authority to slap tariffs as steep as 100 % on any country that keeps buying Russian crude oil or gas.

That clause alone sends a ripple through the global energy market, especially for the two biggest importers of Russian oil – China and India. Between December 2022 and August 2026, China took roughly half of Moscow’s oil exports, while India’s share hovered around 37 %. Together they account for most of Russia’s oil revenue, so any punitive measure could have a domino effect.

Now, don’t assume the law automatically means a full‑blown 100 % duty on Indian or Chinese shipments. The act simply gives the president the green light to impose such tariffs – the actual level, timing and scope will depend on what the White House decides next. In other words, it’s a threat that can be wielded, not a sentence that’s already been handed down.

The legislation does more than target oil. It also spells out sanctions on a litany of Russian entities – political figures, state‑linked banks, and even vessels that belong to the so‑called “shadow fleet.” On the Iranian side, the law adds pressure on energy and weapons sectors, broadening the sanctions net.

For India, the headline is clear: energy security and economic imperatives will continue to shape its crude buying decisions. New Delhi has long warned that its oil imports are driven by pragmatic needs, not political alignment. Yet the specter of a possible 100 % tariff looms large, forcing Indian policymakers to weigh the cost of staying the course against the risk of pivoting to other suppliers.

Meanwhile, Beijing watches closely. If Washington decides to go after China’s oil purchases, the bilateral trade dynamics could shift dramatically. Both countries, already navigating a delicate dance with the U.S., may find themselves scrambling for alternatives, whether that means shifting to alternative energy sources or deepening ties with other oil‑producing nations.

All told, the new sanctions law adds another layer of tension to already fraught geopolitics. The world will be watching how the U.S. uses this newfound tariff authority – and whether India and China will have to rewrite their energy playbooks in response.
