Trump Warns of Tariffs Up to 300% for Firms That Do Not Build in the US

Direct answer

President Donald Trump said on November 5, 2026 that foreign companies that do not build factories in the United States could face tariffs of 50 percent, 100 percent, 150 percent, 250 percent, or even 300 percent. He gave no list of countries or products, no legal basis, and no start date, so this is a warning, not a new tariff that has taken effect.

What happened

Speaking to reporters in the Oval Office on November 5, two days after the midterm elections, Trump defended his tariff policy and said it is the reason foreign companies are building factories in the United States. He said more than 3,000 factories are under construction, and argued that if the tariffs were removed, every one of those plants would stop building at once.

He said companies are building in the US because otherwise, to sell their products in the United States, they would have to pay tariffs of 50, 100, 150, 250, or even 300 percent. Once a factory opens, he said, the company pays no tariff. He also said he has a lot in the works and that people will see more actions over the next week or two, but he did not give details.

The remarks came after Democrats won majorities in both the House and the Senate in the November 3 midterms. House Minority Leader Hakeem Jeffries, the front runner to become the next House speaker, has pledged to repeal Trump’s tariffs within the first 100 days of the new Congress, which convenes in January 2027.

Why it matters for beginners

A tariff is a tax on goods brought into a country. When the US puts a tariff on imported goods, the importer usually pays it, and the extra cost often reaches shoppers through higher prices. A 300 percent tariff would mean a product that costs 100 dollars abroad would face 300 dollars in tax at the border, which would make it far too expensive for most buyers.

That is why this warning matters even though no new tariff has been announced yet. Companies that sell into the US, from car makers to phone makers, have to decide whether to build factories in America or risk very high taxes on their goods. Those decisions affect jobs, prices, and where products are made.

For beginners, the key point is simple. Tariffs are being used as a tool to push companies to make things in the United States. The threat of a 300 percent rate is the strongest version of that push so far, but until a formal order names the products, the countries, and the date, it stays a threat rather than a charge shoppers will pay.

What to watch next

Watch for any formal tariff order from the White House in the next one to two weeks, and for which products or countries it names, if any. Watch how Democrats in the new Congress respond, since they have said they will move to repeal some tariffs in early 2027. Watch company announcements too: if big foreign firms speed up US factory plans, the threat is working as intended. And watch prices, because if high tariffs do take effect on everyday goods, shoppers would feel it first.

FAQ

What is a tariff?

A tariff is a tax charged on goods imported into a country. The importer pays it to the government, and the cost is often passed on to buyers through higher prices.

Has the 300 percent tariff started?

No. Trump warned on November 5 that tariffs could reach 300 percent for companies that do not build factories in the US, but he did not announce a formal order, name specific products or countries, or give a start date.

Which companies would be affected?

Trump did not name any company. The warning applies in general to foreign companies that sell goods in the US without building factories there. He mentioned China, Japan, South Korea, and the Philippines as countries the US would import from instead if tariffs were scrapped.

Why did Trump say this now?

He spoke two days after the midterm elections, in which Democrats won both chambers of Congress after campaigning against tariffs and the cost of living. His remarks signaled that he does not plan to soften his tariff policy despite the election result.
