The US tariff threat on India has returned to the centre of the trade and economic conversation.

On September 18, 2026, US President Donald Trump signed the Lindsey O. Graham Sanctioning Russia and Iran Act of 2026 into law. The legislation gives the US President the authority to impose tariffs of up to 100% on countries that continue significant trade with Russia, including major buyers of Russian energy such as India and China.

But there is an important distinction behind the headline.

India has not automatically been hit with a 100% tariff simply because the legislation was signed.

The law creates the authority to impose such tariffs. The eventual impact will depend on the tariff rate, products covered, exemptions and implementation timeline.

That uncertainty is what matters for Indian businesses right now.

The US is a major destination for Indian exports, while Russia has become an important source of India’s crude oil imports. This puts India at the intersection of two major economic priorities: export growth and energy security.

So, what could the latest US tariff threat mean for India?

Why the US tariff threat matters for India

The US is one of India’s largest export markets.

Indian businesses sell a wide range of products to American buyers, including smartphones, pharmaceuticals, jewellery, diamonds, engineering goods, seafood, petroleum products and solar equipment.

This makes any significant change in US trade policy important for India’s export sector.

But the impact will not necessarily be the same across industries.

A company that earns most of its revenue from the US could face a very different situation from one that sells across several international markets. Similarly, a product with strong demand and limited global competition may respond differently to tariffs than a product where buyers can easily switch suppliers.

That is why the headline figure of 100% does not tell us the complete story.

The questions businesses need to watch are more specific:

What tariff rate will actually be imposed?
Which products will be covered?
Will specific sectors receive exemptions?
When would the tariffs come into effect?
How will Indian exporters respond?

Until those details are known, the eventual economic impact remains difficult to quantify.

The Russian oil connection

The latest tariff threat cannot be separated from India’s energy strategy.

India imports most of its crude oil requirements, which makes international oil prices extremely important for the domestic economy.

Russian crude became a significant part of India’s import basket after the global energy market was disrupted by the Russia-Ukraine conflict and subsequent Western sanctions.

For India, buying Russian oil has been closely linked to energy security, refinery economics and the need to maintain adequate crude supplies.

The new US legislation adds another layer to that equation.

If Washington eventually uses the new tariff powers against countries purchasing Russian energy, India could face a difficult balancing act.

Reducing Russian oil purchases could potentially reduce exposure to US tariff pressure. However, replacing those supplies could affect India’s crude import costs depending on global oil prices and the availability of alternative suppliers.

Continuing to purchase Russian crude could, meanwhile, leave Indian exports more exposed to potential US trade measures.

This means a policy decision related to energy could eventually affect India’s exports, currency, inflation and trade balance.

How could US tariffs affect the Indian economy?

The impact would begin with exporters, but it could move through several parts of the economy.

1. Indian exports could face pressure

A high tariff makes Indian products more expensive for US buyers unless exporters, importers or consumers absorb some of the additional cost.

For exporters, that could mean lower margins, weaker demand or a search for alternative markets.

The impact would be particularly relevant for industries where the US accounts for a significant share of overseas sales.

However, exporters may respond by adjusting prices, improving cost efficiency or redirecting shipments to other markets.

This is where India’s ongoing push towards export diversification becomes important.

2. The rupee could come under pressure

Exports generate foreign-currency earnings for India. If tariffs materially reduce demand for Indian goods in the US, export receipts could be affected.

At the same time, if India has to purchase crude from more expensive sources, the country’s import bill could rise.

A combination of weaker export earnings and a higher import bill can put pressure on the rupee.

Currency movements are not determined by trade flows alone, but the export-import balance remains an important part of the external-sector picture.

3. Inflation could be affected

Crude oil is one of the most important variables to watch.

Higher crude prices can raise transportation and production costs across the economy. The impact can eventually spread to fuel, logistics, manufacturing and other sectors.

If replacing Russian crude results in higher sourcing costs, the effect could become relevant for India’s inflation outlook.

For readers interested in how oil prices can influence the domestic market, Alice Blue’s Crude Oil Price $100 Impact on Indian Market provides additional context.

4. The trade deficit could widen

India’s merchandise trade balance is heavily influenced by its large import bill, particularly crude oil.

If exports to the US slow while energy imports become more expensive, India’s merchandise trade deficit could come under additional pressure.

A wider trade deficit does not automatically mean a broader economic downturn. Services exports, capital flows and other external-sector factors also matter.

But it is an important indicator to monitor because persistent pressure on the trade balance can affect the rupee and external financing conditions.

Which Indian sectors could feel the impact?

The eventual sector impact will depend on the products covered by any US tariff.

Electronics

India’s electronics exports to the US have expanded rapidly in recent years. Smartphones have become an increasingly important part of the export basket.

Any significant tariff on this category could therefore become relevant for manufacturers and suppliers operating around India’s electronics-export ecosystem.

Pharmaceuticals

The US is an important market for Indian pharmaceutical companies.

Indian drug manufacturers have built substantial relationships with American buyers, making changes in market access and pricing particularly relevant for the sector.

Gems and jewellery

The US is also a major destination for India’s gems and jewellery exports.

Tariffs could influence final prices, consumer demand and exporter margins depending on the products covered.

Engineering and auto components

Engineering goods, machinery and automotive components represent another important segment of India’s export basket.

Companies in these sectors could face varying degrees of impact depending on their US revenue exposure and ability to diversify customers.

Seafood and other consumer products

Seafood exporters and other consumer-focused industries may also be sensitive to higher import costs if US buyers have alternative suppliers available.

The key takeaway is simple: The impact will be sector-specific, not uniform.

Can India diversify beyond the US?

This may become one of the most important questions for India’s export strategy.

India has been expanding trade relationships across Europe, the Middle East, Asia and other regions.

Trade agreements can improve market access, but diversification does not happen overnight.

A company exporting heavily to the US cannot simply redirect the same volume to another country without considering demand, pricing, logistics, product standards and competition.

Still, having multiple export markets can reduce dependence on any single destination.

That makes diversification valuable even when there is no immediate trade disruption.

India’s broader trade relationship with the US is also still evolving. The latest legislation adds another variable to ongoing negotiations and bilateral economic discussions.
Alice Blue’s India-US Trade Deal Update: Russia Bill Threatens Ambitious Target provides further context on how the Russia-related legislation intersects with India-US trade discussions.

What could this mean for Indian stock markets?

The tariff issue could reach financial markets through several channels. Export-oriented companies could face concerns around US demand and margins. Oil-sensitive sectors could react to changes in crude prices. Companies with significant foreign-currency exposure could be affected by movements in the rupee.

And broader market sentiment could respond to developments in India-US relations.

However, it would be too simplistic to assume that a tariff announcement automatically means the entire Indian stock market will move in one direction.

Company-level exposure matters.

For example, an exporter with diversified markets may have a different risk profile from a company that generates most of its overseas revenue from the US.

Similarly, a business with strong pricing power may respond differently from one operating on thin margins.

For investors, this makes understanding the underlying economic channels more useful than reacting to the tariff headline alone.

Alice Blue’s coverage of India-US trade delays, tariffs and market risks also looks at how trade uncertainty can intersect with foreign investor sentiment, currency pressure and sector-specific risks.

What should India watch next?

The next phase will depend on what Washington actually decides.

The key indicators to watch are:

The final tariff rate, if imposed
Products and sectors covered
Possible exemptions
Implementation timeline
India’s Russian crude purchases
Global crude oil prices
India-US trade negotiations
Export growth across major sectors
Rupee movement
India’s merchandise trade deficit

These variables will determine whether the current tariff threat remains primarily a geopolitical development or becomes a broader economic issue.

The bigger picture for India

The latest US tariff threat highlights how closely trade, energy and geopolitics are now connected.

For India, the challenge is not simply protecting export growth. It is balancing access to important markets with energy security and maintaining macroeconomic stability.

The US will remain an important market for Indian exporters. At the same time, India’s dependence on imported crude means that changes in global energy trade can have consequences far beyond the oil sector.

For now, the 100% figure should be treated as a potential tariff ceiling under the new law, not as a blanket tariff already imposed on Indian goods.

The real impact will become clearer only when Washington specifies the rate, products covered and implementation timeline.

For Indian businesses, the immediate focus is therefore on preparedness and market diversification.
For the broader economy, the key variables are exports, crude oil, inflation, the rupee and the trade balance.
And for investors, the bigger lesson is that global trade policy can increasingly find its way into company earnings, sector performance and market sentiment.

The question is no longer just how much India exports.

It is also how diversified those exports are, how dependent India is on imported energy, and how resilient the economy can remain when global trade rules change.
