Trump’s 100% Tariff Threat on India: What It Means and How Modi Government Responded

The United States has taken a new step that could create another major trade challenge for India.

On September 18, 2026, U.S. President Donald Trump signed the Lindsey O. Graham Sanctioning Russia and Iran Act of 2026 into law. The legislation expands U.S. sanctions against Russia and gives the President authority to impose tariffs of up to 100% on certain countries that continue purchasing Russian oil or natural gas.

India is one of the world's major buyers of Russian crude oil. As a result, the new law has raised questions about whether Indian exports to the United States could face another substantial tariff increase.

But there is an important distinction:

A 100% tariff has not automatically been imposed on India.

The law gives President Trump the authority to impose tariffs of up to 100% under the relevant provisions. Whether and how that authority is actually used against India is a separate question.

So what exactly has happened, and did the Indian government accept Trump's position?

Let's understand it in simple terms.

What Is the 100% Tariff Issue?

A tariff is a tax imposed on imported goods.

If the United States imposes a 100% tariff on an Indian product, the U.S. importer could face an additional duty equal to the value of the imported product, depending on how the measure is structured and applied.

For example, if an Indian product enters the United States with a customs value of $10,000 and a 100% tariff applies to that product, the additional tariff could be $10,000.

That does not necessarily mean that the Indian exporter directly pays $10,000 to the U.S. government. The tariff is generally collected from the importer under U.S. customs rules, although the economic burden can be shared among importers, exporters and consumers through changes in prices and margins.

This is why a very high tariff can make Indian goods less competitive in the American market.

Why Is Trump Talking About a 100% Tariff?

The issue is connected to Russia and, particularly, Russian energy exports.

The new U.S. legislation is intended to increase economic pressure on Russia. It contains sanctions and other measures directed at Russia's energy sector and also gives the President authority to impose additional tariffs on countries that continue purchasing Russian oil or gas.

India has continued purchasing significant quantities of Russian crude oil.

The United States has previously used tariffs against India in connection with Russian oil purchases. In August 2025, the Trump administration announced an additional 25% tariff on certain imports from India because of India's purchase of Russian oil.

The new 2026 law creates a potentially much broader tool because it authorizes tariffs of up to 100% in specified circumstances.

Has Trump Already Imposed a 100% Tariff on India?

No.

This is one of the most important points to understand.

The signing of the law does not mean that every Indian product entering the United States is now automatically subject to a 100% tariff.

Instead, the law provides the President with authority to impose tariffs of up to 100% against qualifying countries under the legislation.

Therefore, headlines saying that "India now has a 100% tariff" can be misleading if they suggest that the full 100% tariff is already being collected on all Indian exports.

The actual impact depends on whether the Trump administration exercises this authority, what products or countries are covered, and what exemptions or other provisions may apply.

Did the Modi Government Accept the 100% Tariff?

No.

The Indian government did not announce acceptance of a 100% tariff.

Instead, India's Ministry of External Affairs said that India remains committed to protecting the country's energy security and economic interests.

Following the U.S. Congress's passage of the legislation, the Ministry stated that India would continue pursuing energy security through diversified sourcing and evolving market conditions. It also said that India had clearly communicated to U.S. interlocutors the possible implications of the measures for the bilateral relationship and international energy markets.

India also said that it would take necessary measures to protect its trade and economic interests and work with Indian trade and industry bodies to address the implications of the developments.

In other words, India's position was not simply to accept the U.S. tariff threat.

The government's response focused on energy security, economic interests, trade and continued engagement with the United States.

What Was India's Main Argument?

India's central concern is energy security.

India is heavily dependent on imported crude oil. Russian crude became an important source for Indian refiners after changes in global energy markets following Russia's invasion of Ukraine.

India has repeatedly maintained that its energy purchasing decisions are based on national interests, market conditions and the need to maintain reliable energy supplies.

The Indian government therefore emphasized that it would continue to pursue diversified sources of energy rather than allow India's energy security to be determined by a single external supplier or market.

The Ministry of External Affairs also warned that the U.S. measures could have implications beyond the two countries and affect the international energy market.

What Did Prime Minister Narendra Modi Do?

The issue has been handled as part of the broader India-U.S. economic and diplomatic relationship.

India and the United States have already been negotiating trade arrangements. In February 2026, the two governments announced a framework for an interim trade agreement, with the United States stating that it would apply an 18% reciprocal tariff rate to specified Indian-origin goods, subject to the terms of the agreement.

The Trump administration had also previously announced the removal of an additional 25% tariff connected to India's Russian oil purchases after India indicated a commitment to stop purchasing Russian Federation oil.

The later developments show why the Russia-oil issue remains closely connected to U.S.-India trade relations.

India's response to the latest legislation has been to continue diplomatic engagement while emphasizing that the country will protect its economic and energy interests.

Does India Have to Stop Buying Russian Oil?

The new U.S. law does not mean that India automatically becomes legally required under Indian law to stop purchasing Russian oil.

The issue is different.

The United States can use its own laws and sanctions authorities to impose economic consequences on foreign parties or countries under the conditions established by U.S. law.

India, meanwhile, makes its own decisions concerning energy imports and foreign trade.

This creates a potential conflict between India's energy policy and U.S. sanctions policy.

That is one reason the issue is important not only economically but also diplomatically.

What Could Happen to Indian Exporters?

If the United States actually imposes a very high additional tariff on Indian goods, Indian exporters could face several problems.

Indian products could become more expensive for American buyers.

Some U.S. importers could look for suppliers from other countries.

Indian exporters could be forced to reduce their prices to remain competitive, which could put pressure on their profit margins.

Industries that depend heavily on the U.S. market could therefore be particularly sensitive to a major tariff increase.

Potentially affected sectors could include textiles, apparel, leather goods, engineering products, jewellery and other manufactured products, depending on the precise tariff structure and exemptions.

The actual effect would depend on which products are covered.

Could American Consumers Also Feel the Effect?

Yes.

Tariffs are collected from importers, but their economic impact can travel through the supply chain.

If an American company imports a product from India and faces a substantially higher tariff, it may:

• absorb the additional cost;

• negotiate a lower price with the Indian supplier;

• increase the price charged to American customers; or

• shift to another supplier.

Therefore, the ultimate economic burden does not necessarily fall entirely on Indian exporters.

Could the Tariff Affect India's Economy?

A very high tariff on Indian exports to the United States could potentially affect India's export earnings and some industries that rely heavily on American demand.

However, the overall impact on the Indian economy would depend on several factors.

These include the actual tariff imposed, the products covered, the duration of the measure, exemptions, India's ability to redirect exports to other markets and the response of Indian exporters.

It would therefore be premature to say that a 100% tariff automatically means that India's entire economy would suffer a 100% impact.

The number "100%" describes a possible tariff rate under the new U.S. authority—not a 100% contraction of Indian exports or the Indian economy.

What About Petrol and Diesel Prices in India?

This is another important question.

If India significantly reduces purchases of Russian crude and replaces them with crude from other suppliers, the cost of India's oil imports could change.

India imports a large proportion of the crude oil it consumes, so international crude prices and the cost of imported oil are important factors for the Indian economy.

However, it would be incorrect to say that a U.S. tariff automatically means petrol or diesel prices in India will immediately rise by a particular percentage.

Fuel prices depend on several factors, including international crude prices, exchange rates, refining costs, taxes, government policy and domestic pricing decisions.

The impact therefore cannot be calculated simply by looking at the proposed 100% tariff.

Why Is Russia Oil So Important to India?

Russian crude became increasingly important to Indian refiners after Western sanctions and changes in global oil trade following Russia's invasion of Ukraine.

India's purchases of Russian crude increased substantially during this period.

According to reporting based on energy-trade data, India was among the largest buyers of Russian crude in 2026.

For India, Russian oil has therefore become part of a broader strategy of obtaining energy from multiple sources.

For the United States, however, purchases of Russian energy are viewed in the context of efforts to reduce Russia's revenues.

This difference in policy priorities is at the heart of the dispute.

Is India Completely Against the United States?

The situation is more complicated than simply saying that India and the United States are "against" each other.

The two countries have extensive economic and strategic relations, and they have continued discussions on trade and investment.

At the same time, they have differences over tariffs, energy purchases and other economic issues.

The February 2026 U.S.-India joint statement, for example, described an interim trade framework involving reciprocal tariff arrangements and expanded market access.

The current dispute over Russian oil therefore exists alongside broader cooperation between the two countries.

What Happens Next?

The key question is whether President Trump actually uses the new authority to impose tariffs of up to 100% on India.

The law gives the President significant authority, but the existence of that authority is not the same as an automatic 100% tariff on Indian goods.

India is likely to continue diplomatic and trade discussions with Washington while also examining alternative energy sources and protecting its economic interests.

Indian exporters, businesses and investors will therefore need to watch the actual U.S. implementation measures rather than relying only on the headline figure of "100% tariff."

Conclusion

The latest U.S. development is significant, but it needs to be understood correctly.

President Donald Trump signed the Lindsey O. Graham Sanctioning Russia and Iran Act of 2026 on September 18, 2026. The law expands sanctions against Russia and gives the President authority to impose tariffs of up to 100% on certain countries purchasing Russian oil or natural gas.

It does not mean that a blanket 100% tariff has automatically been imposed on all Indian goods.

The Indian government has also not accepted the 100% tariff threat. Instead, India's Ministry of External Affairs has emphasized energy security, protection of trade and economic interests, diversified energy sourcing and continued engagement with the United States.

The next major development will be how the Trump administration chooses to exercise the authority granted by the new law and how India responds.

For ordinary Indians, the possible consequences could eventually involve exports, employment in affected industries, the rupee, energy costs and prices—but the actual effect will depend on the measures ultimately implemented.

Frequently Asked Questions

Is the United States imposing a 100% tariff on India right now?

Not as a blanket tariff on all Indian goods. The September 2026 law gives President Trump authority to impose tariffs of up to 100% in specified circumstances involving countries purchasing Russian energy.

Did Narendra Modi agree to the 100% tariff?

No. The Indian government has not announced acceptance of a 100% tariff. India's stated position has emphasized energy security and protection of its trade and economic interests.

Why is India facing this tariff threat?

The issue is primarily connected to India's purchases of Russian crude oil and the U.S. effort to place economic pressure on Russia.

Does the new law force India to stop buying Russian oil?

It does not directly change Indian law or automatically order India to stop buying Russian oil. It gives the U.S. President additional authority to impose economic measures under U.S. law.

Will petrol prices automatically increase in India?

No. Petrol and diesel prices depend on international crude prices, exchange rates, taxes, refining costs and domestic pricing policies. A U.S. tariff does not automatically translate into a fixed increase in Indian fuel prices.

Will Indian exporters be affected?

They could be if additional U.S. tariffs are actually imposed on their products. The impact would vary by sector, product, exemptions and the final U.S. implementation.
