Trump’s Latest Tariffs Take Effect Against Dozens of Countries

On August 7, 2025, former U.S. President Donald Trump’s sweeping new tariffs formally came into effect, targeting imports from dozens of countries. The move marks a significant escalation in Trump’s “reciprocal trade” strategy, with the U.S. Customs and Border Protection enforcing the new rates starting 12:01 a.m. Eastern Time.

These tariffs impact a broad array of goods and nations. While some allies, including the UK, Japan, South Korea and the EU secured revised or reduced rates through late-stage negotiations, others were not as fortunate. Countries such as Switzerland (39 per cent), Laos and Myanmar (40 per cent), and Syria (41 per cent) face significant hikes. India is expected to see its duties rise to 50 per cent within weeks. Tariffs on specific product categories are particularly severe, with pharmaceuticals facing duties of up to 20 per cent and computer chips facing duties of up to 10 per cent.

The legal foundation for these tariffs lies in the International Emergency Economic Powers Act (IEEPA) of 1977, a law typically used in the context of national security or foreign threats. By invoking IEEPA for economic trade actions, Trump’s team has drawn criticism from legal scholars who argue it stretches the intended use of the statute. Multiple lawsuits have already been filed, challenging the legality of the move and claiming it undermines congressional authority over trade.

Economists warn that these aggressive trade measures could lead to higher prices for American consumers and disrupt global supply chains. Some business leaders are calling for legislative checks on executive authority in trade matters, fearing long-term instability. 

As legal proceedings begin and international reactions unfold, this tariff wave is expected to shape both domestic law debates and global trade relations for the foreseeable future.
