The US Supreme Court struck down President Trump's tariffs imposed under the International Emergency Economic Powers Act (IEEPA), forcing him to use Section 122 of the Trade Act of 1974 to impose a temporary 15% global tariff, reshaping trade dynamics and impacting India-US negotiations.

Key points

US Supreme Court ruling invalidated Trump's tariffs under the International Emergency Economic Powers Act (IEEPA), restoring Congress's primacy in trade policy and constraining presidential authority to weaponize tariffs.

Section 122 of the Trade Act of 1974 was invoked by Trump to impose a temporary 10% tariff, later increased to 15%, on all imports for up to 150 days, citing 'fundamental international payments problems'.

The ruling undermines Trump's differential tariff strategy, potentially affecting recent trade deals with the UK, Japan, EU, and ongoing negotiations with India, as all countries now face a uniform 15% tariff.

Section 232 of the Trade Expansion Act of 1962 and Section 301 of the 1974 Trade Act remain unaffected, allowing tariffs on national security grounds (e.g., steel, aluminium) and unfair trade practices, respectively.

[GS2-International Relations] The ruling reshapes the global trade landscape, prompting India to reconsider its trade deal with the US, as the leverage of reciprocal tariffs under IEEPA is now invalidated.

[GS3-Economy] The removal of IEEPA tariffs could lower America’s effective tariff rate by about half, but the Trump administration aims to offset this with enhanced use of Sections 232 and 301 to maintain tariff revenue.

The temporary nature of Section 122 tariffs (150 days) means the administration must eventually seek Congressional approval, limiting long-term policy stability and creating uncertainty for trading partners.

Legal challenges to Section 122 are anticipated, as it has never been used before, mirroring the controversy surrounding IEEPA's application for tariffs.

Way Forward: India should leverage this ruling to renegotiate trade terms with the US, diversify export markets to reduce dependency on US tariffs, and strengthen multilateral trade frameworks like WTO to counter unilateral tariff measures.

Key terms

Section 232 of the Trade Expansion Act of 1962

Permits tariffs on national security grounds, used for steel, aluminium, and semiconductors. Its continued validity post-ruling underscores the strategic use of trade policy for geopolitical goals.

Most Favoured Nation (MFN) tariffs

Standard non-discriminatory tariffs applied to WTO members. The ruling reverts some US tariffs to MFN rates, reducing preferential treatment and impacting export competitiveness for countries like India.

International Emergency Economic Powers Act (IEEPA)

A 1977 US law granting the President authority to regulate commerce during national emergencies. The Supreme Court's ruling curbed its use for imposing tariffs, reinforcing Congressional oversight over trade policy, a significant check on executive power.

Section 122 of the Trade Act of 1974

A rarely-used provision allowing the US President to impose temporary tariffs (up to 15% for 150 days) to address balance-of-payments crises. Its invocation highlights executive flexibility in trade policy despite judicial constraints.
