WASHINGTON, April 2 (Yonhap) -- U.S. President Donald Trump's administration said Wednesday it will impose 50 percent tariffs on steel, aluminum and copper imports based on their "full value" paid by U.S. customers in America rather than "artificially low" foreign prices.

It also plans to adjust tariffs on derivative metal products, under which no additional sectoral duties will be imposed on products containing less than 15 percent steel, aluminum or copper by weight, while a 25 percent tariff will apply to those exceeding that threshold, a senior U.S. official said in an online briefing.

Trump signed a proclamation on the adjustments that are set to take effect at 12:01 a.m. on Monday (Washington time). The White House said that the changes are intended to strengthen the metal tariffs to "more effectively address the national security threat posed by such imports."

"The proclamation defines the way that tariffs are assessed, ensuring that they reflect the full value of imported steel, aluminum, and copper products -- not an artificially low foreign price," the White House said in a fact sheet.

It appears to suggest that some foreign exporters are artificially manipulating prices to reduce tariff payments.

On the day, Trump also signed a separate document to impose a long-awaited 100 percent tariff on patented pharmaceuticals that are not made in the United States and do not have a most-favored-nation (MFN) pricing agreement with the U.S., according to the official.

But South Korea, Japan, Switzerland and the European Union are not subject to the 100 percent tariff, as those countries have made bilateral trade deals with the U.S., the official said.

As for exceptions, he said that if a company commits to building a pharmaceutical plant in the U.S., its tariff will be reduced to 20 percent. If it is building a plant in the U.S. with an MFN agreement with the U.S., then its tariff will go down to zero, he said.

The official also said that certain big companies will be given 120 days to decide whether to announce "reshoring" plans before the 100 percent tariff kicks in, while smaller companies will have 180 days.

Asked if the Trump administration has concerns about the possibility of metal derivative tariffs affecting affordability for American citizens, the official said that there will be "no impact on affordability whatsoever."

"These will not have an impact on the price of the goods on the shelf," he said.

Both metal and pharmaceutical tariffs are based on Section 232 of the Trade Expansion Act of 1962 -- a law that allows the president to adjust imports into the U.S. when he determines they threaten to impair national security.
