Indian Stocks Dive as Trump Imposes 100% Tariff on Pharma Imports

Indian pharmaceutical stocks declined sharply by up to 5% on Friday following US President Donald Trump’s declaration of imposing 100% tariffs on branded and patent-protected medicines including from India.

India’s Sun Pharma experienced the steepest decline, touching its yearly low at Rs1,547, showing a 5% reduction from its last closing price.

Biocon witnessed a 3.3% fall to Rs344, whilst Zydus Lifesciences declined by 2.8%, settling at Rs990.

Aurobindo Pharma decreased by 2.4% to Rs1,070, and Dr Reddy’s registered a 2.3% decline to Rs1,245.30.

Both Lupin and Cipla saw a 2% reduction, ending at Rs1,923.30 and Rs1,480, respectively.

Torrent Pharma showed the smallest decline of 1.5%, reaching Rs3,480.65.

President Trump on Thursday announced tariffs of up to 100 percent on imports of branded and patented pharmaceutical drugs, starting October 1, 2025.

India’s pharmaceuticals sector, one of the most dependent domestic industries on trade with America, was set to be significantly impacted by the move.

“Starting October 1st, 2025, we will be imposing a 100 percent tariff on any branded or patented pharmaceutical product, unless a company is building their pharmaceutical manufacturing plant in America,” the Republican leader said on Truth Social.

Trump’s posts showed that his devotion to tariffs did not end with the trade frameworks and import taxes that were launched in August. A reflection of the president’s confidence that taxes will help reduce the government’s budget deficit while increasing domestic manufacturing.

In his latest tariff blitz, Trump also slapped 50 percent duty on imports of kitchen cabinets and bathroom vanities, 30 percent on upholstered furniture, and 25 percent on heavy trucks.

While Trump did not provide a legal justification for the tariffs, he appeared to stretch the bounds of his role as commander-in-chief by stating that the taxes were needed “for National Security and other reasons.”

America is India’s largest export market for pharmaceutical goods.

In FY 24, of India’s $27.9 billion worth of pharma exports, 31 percent or $8.7 billion (Rs 77,138 crore) went to the US, according to the Pharmaceuticals Export Promotion Council of India, an industry body.

Another $3.7 billion (Rs 32,505 crore) worth of pharma products were exported in just the first half of 2025.

Per reports, India supplies over 45 percent of generic and 15 percent of biosimilar drugs used in the US.

Firms like Dr Reddy’s, Aurobindo Pharma, Zydus Lifesciences, Sun Pharma and Gland Pharma reportedly earn anywhere from 30-50 percent of their total revenues from the American market.

Although the latest American tariffs appear to mainly target branded and patented drugs a segment dominated by multinational giants uncertainty looms over whether complex generics and speciality medicines from India would also be under the scanner.

Moreover, large players already have manufacturing facilities in the US.

American consumers depend on low-cost generics manufactured in India.

Higher tariffs would lead to price hikes, inflation and drug shortages in the country.

Meanwhile, Indian companies, operating on thin margins in the US generics space, may struggle to absorb costs if tariffs are imposed on them, and end up passing them on to US consumers or insurers.

Trump has already slapped 50 percent tariffs on Indian imports, which also includes a 25 percent ‘penalty’ for continued purchase of Russian oil.
