The US 100% tariff on India has emerged as a serious economic and energy-security risk after US President Donald Trump signed legislation giving his administration the power to impose tariffs of up to 100% on countries that continue buying Russian oil. India, one of the largest buyers of Russian crude, is among the countries most exposed to the measure, along with China, Slovakia, Hungary and Azerbaijan, according to the report by Aaj Tak Business.
The legislation does not automatically impose a 100% tariff on India. It gives the US administration the authority to take that step. The distinction is important because the immediate impact is not a new tariff rate but a significant increase in uncertainty for two systems that are closely connected: India’s energy procurement and its exports to the United States.
The law, named the Lindsay O. Graham Sanctioning Russia and Iran Act of 2026, was passed by the US Senate by 86 votes to 11 in August, according to the supplied report. The White House subsequently said that Trump had signed it. The law extends existing sanctions on Iran and allows tariffs of up to 100% to be imposed on countries purchasing Russian oil and gas. The list of affected countries is to be reviewed by the US Trade Representative every 180 days.
That review mechanism places India’s trade relationship with the US within a recurring policy process rather than a one-time decision. The administration can assess countries periodically, creating a continuing risk for exporters, refiners and companies negotiating contracts across the two markets. The supplied report does not establish that the US has decided to apply the maximum tariff to India, but it identifies India as a prominent target because of its Russian oil purchases.
The issue has become significant because Russian crude has taken a large place in India’s oil supply since the Russia-Ukraine war began. The report says India currently sources more than 40% of its total oil requirement from Russia. It also cites figures showing that India bought approximately 2.08 million barrels per day of Russian crude in August 2026, compared with 2.82 million barrels per day in July.
These figures point to the central policy dilemma. Russian crude has been available to India at discounted rates, helping refiners manage the cost of imported energy. If tariff pressure forces India to reduce those purchases and seek supplies from West Asia, the United States, Africa or other markets, the replacement cost could be higher. The actual difference would depend on global crude prices, freight costs, refinery requirements and availability, all of which the supplied material identifies as relevant variables.
A shift away from Russian oil would therefore affect more than the sourcing decisions of individual refiners. It could raise India’s overall import bill and put additional pressure on the trade balance. Higher crude costs also create a risk of increased domestic inflation, particularly through petrol and diesel prices. The source report identifies this as a potential impact on households, although it does not provide a forecast of the size or timing of any price increase.
The energy question is closely tied to the export question. India currently faces a 10% US tariff, according to the report. If the new legislation were used to impose a 100% tariff on Indian goods because of continued Russian oil purchases, Indian products would become substantially more expensive in the American market. The report says this could put export orders at risk as buyers shift towards lower-priced products from Bangladesh, Vietnam or other countries.
The exposure is spread across several major export categories, including textiles, pharmaceuticals, gems and jewellery, engineering goods, leather, marine products and chemicals. These sectors are not affected in the same way, and the supplied material does not specify which products would face the greatest reduction in demand. But their inclusion in the report shows why the tariff threat extends beyond crude oil and foreign policy. It reaches factories, supply chains, exporters and workers whose market access depends on competitive pricing.
The trade figures cited in the report demonstrate the scale of the relationship. India’s merchandise exports to the US reached $8.4 billion in August 2026, an increase of 21.83% over the same period of the previous financial year. Imports from the US rose 65.78% to $5.97 billion. These figures show a substantial flow of goods in both directions, making the consequences of a sharp tariff increase potentially wider than a dispute involving one product category.
The report also provides a recent comparison that illustrates how tariff policy can affect trade flows. Between September 2025 and February 2026, when a 50% tariff was in place, India’s average monthly exports to the US fell to $6.5 billion from $8.1 billion in the preceding six months. After the tariff rate was reduced to 10%, exports increased again, according to the figures cited from a Press Trust of India report.
This pattern does not prove that tariff changes alone caused the movement in exports. The supplied material does not provide a sector-wise breakdown, details of exchange-rate movements or information on changes in demand during those periods. It does, however, establish the commercial sensitivity of the India-US relationship to tariff levels. A move from 10% to 100% would represent a far larger disruption than the change described in the report.
The institutional structure behind the possible tariff also matters. The US legislation gives the administration a mechanism to review countries every 180 days, while the US Trade Representative would be involved in evaluating the list. That means any response from India would have to address both the immediate threat and the possibility of repeated reviews. The measure is not described in the supplied material as an automatic penalty linked to a fixed volume of oil purchases; its implementation would depend on decisions made under the new law.
For India, the policy choices are connected but difficult to separate. Reducing Russian oil purchases could limit exposure to the proposed US tariff, but it could also remove access to discounted crude and increase the cost of energy imports. Continuing purchases could protect supply arrangements and refinery economics while raising the risk of punitive action against Indian exports. The report does not establish what decision India will take or whether an alternative arrangement with the US is under negotiation.
India has nevertheless responded publicly to the pressure. According to the supplied report, the Indian government has said that national interests will not be compromised. That statement indicates the issue has moved beyond a commercial tariff dispute into the area of energy security and foreign-policy autonomy. The report also says the measure could affect ongoing India-US trade negotiations, although it does not provide details of the negotiating positions or the next scheduled round.
The urban consequences are indirect but material. Energy costs influence transport, logistics, manufacturing and household expenditure across cities. Export-oriented industrial clusters depend on predictable access to overseas markets, while higher fuel costs can raise the operating expenses of freight, public transport and construction supply chains. The supplied report does not quantify these effects, but the link between crude prices, trade costs and urban economic activity is central to understanding why the tariff threat matters beyond national trade statistics.
The evidence currently confirms three things: the US has enacted legislation permitting tariffs of up to 100% against countries buying Russian oil and gas; India is identified as one of the principal countries exposed because of its Russian crude imports; and bilateral trade is large enough for a major tariff change to affect multiple export sectors. What remains uncertain is whether the maximum tariff will be imposed, how the US administration will apply the 180-day review process, and how India will balance discounted energy supplies against access to the US market.
Those decisions will determine whether the legislation remains a negotiating threat or becomes a direct shock to India’s energy costs and exports. The next milestones are the US administration’s implementation decisions, the periodic country-list review by the US Trade Representative and the progress of India-US trade talks.
