The administration of Donald Trump on Wednesday launched a new trade investigation into excess industrial capacity in 16 major trading partners, including India.

This move may pave the way for fresh tariffs or other trade restrictions.

According to Reuters, the office of Jamieson Greer, the US Trade Representative under the administration of Donald Trump, has launched a “Section 301” investigation into alleged unfair trade practices linked to excess industrial capacity among key trading partners.

The probe could lead to new tariffs as early as this summer on imports from major economies including China, the European Union, India, Japan, South Korea and Mexico.

Other economies covered under the excess capacity investigation include Taiwan, Vietnam, Thailand, Malaysia, Cambodia, Singapore, Indonesia, Bangladesh, Switzerland and Norway.

Notably, Canada — the second-largest trading partner of the United States — was not listed among the targets of the probe.

What is Section 301?

Section 301 of the Trade Act of 1974 is one of the most powerful instruments the United States uses to challenge what it considers unfair trade practices by other countries. The provision allows the Office of the US Trade Representative (USTR) to investigate foreign policies, regulations, or trade barriers that may harm American companies, limit market access, or put its exports at a disadvantage.

Once a probe begins, the USTR collects evidence through public submissions. There are hearings consultations with the country involved and industry groups to assess whether the allegations are valid.

If the investigation determines that the practices are unfair or discriminatory, the US government can respond with unilateral measures. These may include imposing higher tariffs on imports, restricting certain services, or introducing other trade penalties. The provision has been used in several major disputes — most notably during trade tensions between the United States and China.

Why is India on list?

India’s inclusion in the probe reflects long-standing concerns in Washington over trade policies that are seen as restricting access for American companies to the Indian market. US officials have often pointed to relatively high tariffs on certain imports, requirements related to local sourcing and data localisation, regulations affecting technology and digital services, and price controls in sectors such as pharmaceuticals.

Although trade negotiations between India and the United States have been ongoing for years, these measures are frequently viewed by Washington as obstacles for American businesses. This has made India a likely candidate for scrutiny under the Section 301 trade review mechanism.
