Trump launches ‘Section 301’ tariff probes against 16 US trading partners, including India, China and the EU.

Trump Administration Launches ‘Section 301’ Trade Probes Into India, China and 16 Other Economies

The Donald Trump administration has launched sweeping trade investigations under Section 301 into India, China and 16 other major economies, alleging that their industrial policies have created excess manufacturing capacity that harms American producers. The move could pave the way for fresh US import tariffs.

On Wednesday, the Office of the United States Trade Representative (USTR) announced two separate probes under Section 301 of the Trade Act of 1974. One investigation will examine excess industrial capacity among key trading partners — including India — while the second will focus on goods allegedly produced using forced labour.

Section 301 allows the US government to investigate and respond to trade practices it considers unfair or harmful to American businesses. The law is one of Washington’s most powerful unilateral trade enforcement tools and allows the US to impose trade measures without approval from the World Trade Organisation (WTO).

The move comes as Trump seeks to revive his global tariff strategy after the US Supreme Court struck down his earlier tariff programme, ruling that imposing tariffs by declaring an economic emergency was unconstitutional.

“The policy remains the same. The tools may change depending on the vagaries of courts and other things,” US Trade Representative Jamieson Greer said, emphasising that the administration’s goal is to protect American jobs.

Along with India and China, the investigation covers the European Union, Japan, South Korea, Mexico, Taiwan, Vietnam, Thailand, Malaysia, Cambodia, Singapore, Indonesia, Bangladesh, Switzerland and Norway.

Greer said the probe will focus on countries where manufacturing output appears disconnected from actual market demand.

“These investigations will focus on economies that appear to exhibit structural excess capacity and production in various manufacturing sectors, such as through persistent trade surpluses or underutilised capacity,” he told reporters during a conference call.

He added that the investigation will examine whether government policies — including subsidies, suppressed wages, support for state-owned enterprises and subsidised lending — allow companies to produce more goods than global demand requires, potentially harming US industries.

Global Manufacturing Capacity Under Scrutiny

According to the Trump administration, the probe will analyse indicators such as persistent trade surpluses, unused industrial capacity and state-backed production policies that could give foreign manufacturers an advantage over American firms.

The USTR has raised concerns about rapidly expanding manufacturing capacity in several countries, particularly in sectors such as automobiles and advanced manufacturing.

For example, the investigation cited Chinese electric vehicle manufacturer BYD, which has been aggressively expanding overseas production despite domestic EV capacity already exceeding demand. The company has established factories in Uzbekistan, Thailand, Brazil, Hungary and Turkey, with further expansion planned in Europe.

Officials also pointed to what they described as imbalances in global production, including high exports from some European economies and state-supported industrial output in parts of Asia.

Alongside the manufacturing probe, the USTR will launch a separate Section 301 investigation targeting goods produced using forced labour. The inquiry could cover more than 60 countries and potentially expand restrictions similar to those already imposed on imports linked to China’s Xinjiang region under the Uyghur Forced Labour Protection Act.

The United States has previously accused Chinese authorities of forcing members of the Uyghur and other Muslim minorities into labour camps — allegations that Beijing denies.

Greer said Washington wants its trading partners to adopt enforcement measures similar to US laws that restrict imports linked to forced labour.

Timeline for Possible Tariffs

The USTR has set April 15 as the deadline for public comments on the excess capacity investigation, with a public hearing expected in early May.

Officials aim to complete the probe and recommend possible tariff measures before the temporary tariffs imposed in February expire in July.

The investigation could also intensify global trade tensions, particularly if new tariffs are imposed on major economies such as India, China and the European Union.

For India, the probe introduces fresh uncertainty into trade relations with Washington, as the US administration explores new legal avenues to revive its tariff strategy following the court ruling.
