NEW YORK / WASHINGTON - US President Donald Trump said Wednesday that the United States will impose a 25-percent tariff on imports from India, starting on August 1, while announcing a "full and complete" trade deal with South Korea, setting 15-percent tariffs on its exports.

Trump also signed an executive order implementing an additional 40-percent tariff on Brazilian goods, bringing the total tariff amount to 50 percent, the White House said in a fact sheet.

In a Truth Social post, Trump said that, despite India being "our friend," the United States has done "relatively little business with them because their tariffs are far too high," adding that India has the "most strenuous and obnoxious non-monetary trade barriers of any country."

He also said that India "has always bought a vast majority of military equipment from Russia, and is Russia's largest buyer of energy."

Therefore, he continued, India will pay a tariff of 25 percent, plus "a penalty for the above," starting on the first day next month.

US Trade Representative Jamieson Greer told CNBC on Monday that the United States needed more time for talks with India to gauge the country's willingness to open its market more to American goods.

Bloomberg reported Tuesday that any rate of 20 percent or higher would come as a disappointment for India, which had been seeking a better deal than the 19 percent that Trump had offered Indonesia and the Philippines.

S. Korea

Also on Wednesday, Trump announced a trade deal with South Korea, adding that Seoul has agreed to invest $350 billion in projects "owned and controlled by the United States," and selected by Trump himself.

"We have agreed to a Tariff for South Korea of 15%. America will not be charged a Tariff," Trump said in a post on his Truth Social platform.

He said South Korea will also purchase $100 billion of liquefied natural gas or other energy products from the United States, along with an additional unspecified "large sum of money," of which the number will be announced within the next two weeks when South Korean President Lee Jae-myung visits the White House for a bilateral meeting.

"I would also like to congratulate the new President on his Electoral Success. It is also agreed that South Korea will be completely OPEN TO TRADE with the United States, and that they will accept American products including Cars and Trucks, Agriculture, etc," Trump said.

Brazil

Meanwhile, the White House claimed that the new tariff measure on Brazilian goods deals with "recent policies, practices, and actions by the Government of Brazil that constitute an unusual and extraordinary threat to the national security, foreign policy, and economy of the United States."

Recently, members of the Brazilian government have taken actions to "coerce US companies to censor political speech, deplatform users, turn over sensitive US user data, or change their content moderation policies on pain of extraordinary fines, criminal prosecution, asset freezes, or complete exclusion from the Brazilian market," according to the White House.

On July 9, Trump announced plans to impose steep tariffs on Brazil, linking the move to his opposition to former Brazilian President Jair Bolsonaro's trial for an alleged attempt to seize power after losing his reelection bid in 2022.

In mid-July, Washington suspended visas for eight Brazilian Supreme Federal Court justices overseeing Bolsonaro's trial.

Brazilian President Luiz Inacio Lula da Silva said on July 17 that Brazil would not tolerate foreign interference in its internal affairs, amid growing tensions with the United States over new tariffs and digital regulations.

"We won't accept interference from any foreign country," Lula said. He pledged a civil and democratic response, while announcing that US-based digital platforms would be required to comply with Brazilian laws and pay taxes. He accused the companies of fueling disinformation and harming Brazilian society.

De minimis treatment for low-value shipments suspended

Trump also issued an executive order on Wednesday suspending duty-free de minimis treatment for low-value shipments.

Effective on Aug 29, imported goods sent through means other than the international postal network that are valued at or under $800 and that would otherwise qualify for the de minimis exemption will be subject to all applicable duties.

For goods shipped through the international postal system, packages will instead be subject to a duty equal to the effective tariff rate applicable to the country of origin, or a duty ranging from 80 to 200 dollars per item

50% tariff on certain copper products

Trump also signed on Wednesday a proclamation to address the effects of copper imports, imposing universal 50 percent tariffs on imports of semi-finished copper products and copper-intensive derivative products, effective on Aug 1.

The proclamation directs the US secretary of commerce to establish a product "inclusion" process to add copper derivative products to these tariffs, and the president is authorizing the secretary of commerce to take steps under the Defense Production Act to support the domestic copper industry, the White House said in a fact sheet.

"By taking these actions, President Trump is leveling the playing field for US copper businesses to support a strong domestic copper industry," the White House added.

Copper is essential to the manufacturing foundation on which US national and economic security depend, and is a necessary input in a range of defense systems, including aircraft, ground vehicles, ships, submarines, missiles and ammunition, according to the fact sheet.
