US Senate passes bill allowing tariffs up to 100% on major buyers of Russian energy

Senate approves expanded sanctions authority

The US Senate has passed a broad Russia sanctions bill that could expose major buyers of Russian oil and natural gas to tariffs of up to 100% on their goods entering the United States. The legislation passed by 86 votes to 11, according to the Associated Press and Axios, giving the measure substantial bipartisan support but not making it law. It must also pass the House of Representatives before it can be sent to President Donald Trump.

The tariff provision focuses on the five largest purchasers of Russian oil or natural gas. China and India are specifically identified among the countries that could be affected. The legislation gives the president authority to apply the tariffs rather than imposing an automatic universal charge on every country trading with Russia. This distinction leaves the timing, country coverage and final tariff rate dependent on executive decisions if the bill completes the legislative process.

Maximum tariff reduced from 500% to 100%

The Senate text is narrower than an earlier version of the proposal. The Indian Express reported that the original bill contemplated a blanket tariff of 500% on countries purchasing Russian energy, while the revised measure caps potential tariffs at 100% and limits them to the five largest buyers of Russian oil and gas. Business Standard reported that lawmakers could reassess the list of leading purchasers every 180 days, allowing coverage to change as trade flows shift.

The reduction does not remove the commercial risk. A tariff of up to 100% could sharply weaken the competitiveness of affected countries’ exports in the US market. For refiners and crude traders, the bill creates a potential link between Russian feedstock purchases and access to the United States across unrelated product categories. Companies may therefore need to evaluate Russian crude discounts against a broader exposure involving manufactured goods, supply contracts and US customers.

India and China face the clearest exposure

India and China have become central markets for Russian energy, and the tariff mechanism is designed to pressure large buyers rather than restrict Russian cargoes only through direct sanctions. The Associated Press said the legislation would allow tariffs on the world’s top five purchasers and named China and India among them. The Indian Express described India as Russia’s second-largest export market for crude oil.

The immediate effect is political and contractual rather than a new border charge. No tariff under this bill can take effect unless the measure becomes law and the presidential authority is exercised. Importers, exporters and refiners consequently face uncertainty over implementation, exemptions and the period available to alter supply arrangements. Any reduction in purchases by major Asian refiners could force Russian sellers to offer larger discounts, seek alternative destinations or absorb higher logistics costs.

Iran provisions broaden the bill’s reach

The package also renews or expands measures involving Iran. The Associated Press reported that it combines pressure on Russia with President Trump’s push for Iran sanctions, while the Indian Express said it calls for sanctions intended to limit Iran’s ability to sustain its wartime economy. The current material does not establish that all trade with Iran would automatically trigger a 100% tariff; the precise consequences would depend on the enacted provisions and their implementation.

For commodity markets, the main issue is whether Washington ultimately uses the authority against large economies with extensive trade ties to the United States. Aggressive implementation could redirect crude flows and increase compliance costs without immediately removing Russian barrels from the global market. Limited or selective implementation would preserve more room for India, China and other buyers to negotiate with Washington while maintaining at least part of their Russian supply.
