US President Donald Trump's administration is considering new national security tariffs on a half-dozen industries after a Supreme Court decision last week that invalidated many of his second-term levies, the Wall Street Journal (WSJ) reported on Monday.

The source said that the new tariffs, to be issued under Section 232 of the Trade Expansion Act of 1962, would be separate from a 15% global levy US President announced on Saturday.

The report added that the new tariffs could cover industries like large-scale batteries, cast iron and iron fittings, plastic piping, industrial chemicals and power grid and telecom equipment.

Market reaction

At the time of press, the US Dollar Index (DXY) was down 0.07% on the day at 97.70.

Tariffs FAQs

What are tariffs?

Tariffs are customs duties levied on certain merchandise imports or a category of products. Tariffs are designed to help local producers and manufacturers be more competitive in the market by providing a price advantage over similar goods that can be imported. Tariffs are widely used as tools of protectionism, along with trade barriers and import quotas.

What is the difference between taxes and tariffs?

Although tariffs and taxes both generate government revenue to fund public goods and services, they have several distinctions. Tariffs are prepaid at the port of entry, while taxes are paid at the time of purchase. Taxes are imposed on individual taxpayers and businesses, while tariffs are paid by importers.

Are tariffs good or bad?

There are two schools of thought among economists regarding the usage of tariffs. While some argue that tariffs are necessary to protect domestic industries and address trade imbalances, others see them as a harmful tool that could potentially drive prices higher over the long term and lead to a damaging trade war by encouraging tit-for-tat tariffs.

What is US President Donald Trump’s tariff plan?

During the run-up to the presidential election in November 2024, Donald Trump made it clear that he intends to use tariffs to support the US economy and American producers. In 2024, Mexico, China and Canada accounted for 42% of total US imports. In this period, Mexico stood out as the top exporter with $466.6 billion, according to the US Census Bureau. Hence, Trump wants to focus on these three nations when imposing tariffs. He also plans to use the revenue generated through tariffs to lower personal income taxes.

How Japan became the World's Banker and why that era may be ending
