Trump Signs Russia-Iran Sanctions Law: What the New 100% Tariff Power Could Mean for India
The United States has entered a new phase in its economic pressure campaign against Russia and Iran. On September 18, 2026, US President Donald Trump signed the Lindsey O. Graham Sanctioning Russia and Iran Act of 2026, a law that expands sanctions against Russia and Iran while giving the US president significant authority to impose tariffs on countries that continue purchasing Russian energy.
India has attracted particular attention because it remains one of the major buyers of Russian crude oil. The legislation allows tariffs of up to 100% on qualifying countries, meaning Indian exports to the US could potentially face another major trade-related challenge. However, the law itself does not automatically impose a 100% tariff on India. The actual impact will depend on how the Trump administration implements the legislation.
What Is the New Russia-Iran Sanctions Law?
The legislation is designed primarily to increase economic pressure on Russia. It targets areas including Russia's energy and defence sectors and takes action against vessels and other entities associated with efforts to evade sanctions.
The law also extends existing sanctions-related measures concerning Iran. One of its most significant provisions, however, concerns countries that purchase Russian oil and gas.
Under the legislation, the US president has authority to impose tariffs of as much as 100% on goods imported from countries that fall within specified categories of major Russian energy purchasers or sanctions-evasion facilitators.
The law provides criteria involving the largest purchasers of Russian crude oil or natural gas and also gives the administration discretion concerning implementation, tariff levels and certain waivers.
Why Is India Mentioned?
India has become one of the world's major purchasers of Russian crude since the Russia-Ukraine conflict began in 2022.
Russian oil became particularly attractive to Indian refiners because discounted supplies helped them manage the country's large energy requirements. According to figures cited by the Economic Times, India imported about $40.8 billion worth of Russian crude in FY2026, representing 30.3% of its total crude imports. Russia's share reportedly rose further during 2026.
This dependence is now at the centre of the latest US-India trade tension.
The 100% Tariff Is a Possibility, Not an Immediate Duty
One of the most important points for Indian businesses and consumers is the distinction between authorisation and implementation.
Trump's signature gives the administration new legal authority. It does not mean that every Indian product entering the United States will immediately face a 100% tariff.
The law provides a framework under which tariffs can be introduced. The administration still has to determine how the provisions will be applied, which countries qualify and what tariff rates will actually be used. Reuters reported that the legislation contains broad language and leaves substantial discretion to the US president.
That uncertainty itself could become an economic issue.
Companies making investment and export decisions generally need predictable tariff structures. Even before an additional duty is imposed, uncertainty about future market access can affect contracts, shipments and business planning.
Why Russian Oil Matters So Much to India
India is one of the world's largest oil importers, making crude availability and pricing important to almost every part of the economy.
Petroleum affects transportation, manufacturing, logistics, agriculture and household expenses. A major reduction in access to a significant source of crude could therefore have consequences beyond the oil industry.
Indian refiners have increased purchases from several countries over time, meaning Russia is not India's only supplier. However, Russian crude has become an important part of the country's import mix.
India's government has repeatedly stressed the importance of energy security and maintaining diversified sources of supply. It has also communicated concerns to Washington about the potential effect of the US legislation on bilateral relations and global energy markets.
The Cost Question
If Indian refiners had to rapidly replace large volumes of Russian crude, alternative supplies could potentially come at different prices.
The final effect would depend on global oil availability, shipping costs, refinery compatibility, currency movements and other market conditions.
This is particularly relevant because changes in crude prices can eventually influence petrol, diesel, transportation and production costs.
What Could Happen to Indian Exporters?
The biggest direct concern is India's exports to the United States.
The US is an important destination for Indian products, and a substantial increase in tariffs could make some Indian goods more expensive for American buyers.
Industries that compete heavily on price could face particular pressure if their products become significantly more expensive after entering the US market.
Possible effects could include:
- Reduced competitiveness of Indian products in the US
- Lower export orders for some businesses
- Pressure on exporters' profit margins
- Greater uncertainty over long-term contracts
- Possible relocation of some orders to alternative suppliers
- Increased pressure on Indian businesses to diversify their export markets
Economic analysts quoted by the Economic Times have cautioned that the consequences cannot be fully assessed until Washington announces the actual tariff rates, product coverage and implementation timetable.
Impact on India-US Trade Relations
The new legislation arrives at a sensitive point in India-US economic relations.
The two countries have been working toward broader trade arrangements while also dealing with disagreements over tariffs and market access.
A new threat of substantially higher tariffs could make those negotiations more complicated.
For India, the challenge is balancing several objectives at the same time: maintaining affordable energy supplies, protecting export interests and continuing engagement with one of its most important trading partners.
For the United States, the legislation is intended to increase pressure on countries that purchase Russian energy and thereby strengthen economic pressure on Moscow.
These objectives can collide because energy trade and merchandise trade are closely connected through international markets.
Could Indian Consumers Feel the Impact?
The effect on consumers is not straightforward.
A higher US tariff primarily affects trade between Indian exporters and American importers. It does not automatically mean that Indian consumers will pay higher prices for everyday goods.
However, if India's cost of importing crude rises substantially, the consequences could eventually spread through the economy.
Fuel prices influence transportation costs, which can affect logistics and the movement of goods. Businesses may also face higher input costs if energy becomes more expensive.
On the other hand, the actual outcome would depend on how India adjusts its crude sourcing and how global oil prices respond.
What Options Does India Have?
India has several possible policy responses, although each involves trade-offs.
Diversifying Crude Suppliers
India can increase purchases from countries other than Russia. Diversification can reduce dependence on any single supplier, although replacement supplies must be available at suitable prices and in sufficient quantities.
Negotiating With Washington
Diplomatic and trade negotiations could become especially important.
India has already communicated its concerns regarding the legislation and its potential effects on bilateral ties and energy markets.
Future discussions could focus on exemptions, implementation arrangements, tariff levels or other mechanisms.
Expanding Export Markets
Indian businesses may also look more closely at markets outside the United States.
Greater diversification could reduce the risks associated with depending heavily on one export destination, although developing new markets takes time.
What Should Businesses Watch Next?
The next stage will be particularly important.
Businesses should watch for announcements from Washington concerning:
- Which countries are formally identified under the legislation
- Whether India is included
- The actual tariff rate
- Which products are covered
- When the tariffs would begin
- Whether exemptions or waivers are available
- How long the measures will remain in effect
The law's provisions take effect within 30 days of signing, according to the Economic Times report, while specific implementation decisions remain important to determining India's actual exposure.
Broader Impact on Global Energy Markets
The issue goes beyond India and the United States.
Russia is a major participant in global energy markets, while countries across Asia and Europe depend on international crude and gas supplies.
If significant volumes of Russian energy were suddenly removed from global trade, buyers would need to find alternative supplies. That could increase competition for crude and potentially create additional price volatility.
Reuters reported that analysts have warned that replacing Russian supplies quickly could be difficult because global spare production capacity is limited.
At the same time, the actual impact will depend on how governments, oil producers, refiners and traders respond.
Frequently Asked Questions
1. Has the US imposed a 100% tariff on India?
No. The law authorises the US president to impose tariffs of up to 100% on qualifying countries, but signing the legislation does not itself mean that India has been given a 100% tariff.
2. Why could India be affected?
India is a major purchaser of Russian crude oil, and the new US legislation specifically creates tariff authority aimed at countries purchasing Russian energy.
3. Will all Indian products face a 100% tariff?
That cannot be determined from the law's signing alone. The eventual product coverage and tariff rate will depend on how the US administration implements the provisions.
4. Why does India buy Russian oil?
Russian crude became an important source for Indian refiners after 2022, particularly because discounted Russian supplies provided an economically attractive source of crude.
5. Could petrol and diesel become more expensive in India?
Potentially, but there is no automatic price increase resulting from the US legislation. The outcome would depend on crude prices, alternative supplies, refining economics and India's energy policies.
6. Could Indian exports to America be affected?
Yes, if additional tariffs are actually imposed. Higher duties could make Indian products more expensive in the US market and could affect exporters' competitiveness.
7. What happens next?
The key development will be how the Trump administration implements the new law, including which countries and products are covered and what tariff rates are selected.
Conclusion
The signing of the Russia-Iran sanctions law creates a new layer of uncertainty for India's trade and energy relationship with the United States. The possibility of tariffs reaching 100% is significant, but it is important not to confuse the legal authority to impose such tariffs with an immediate 100% duty on Indian goods.
For India, the central challenge is managing energy security while protecting access to important export markets. Russian crude has become an important part of India's energy mix, while the United States remains a major destination for Indian exports.
The coming weeks will therefore be closely watched by Indian exporters, refiners, investors and policymakers. The actual economic consequences will depend less on the headline 100% figure and more on the specific decisions Washington ultimately makes regarding implementation, exemptions, product coverage and tariff rates.
