Washington, Jul 16 (AP) President Donald Trump told reporters Tuesday that he plans to place tariffs of over 10 per cent on smaller countries, including nations in Africa and the Caribbean.

"We'll probably set one tariff for all of them," Trump said, adding that it could be "a little over 10 per cent tariff" on goods from at least 100 nations.

Commerce Secretary Howard Lutnick interjected that the nations with goods being taxed at these rates would be in Africa and the Caribbean, places that generally do relatively modest levels of trade with the US and would be relatively insignificant for addressing Trump's goals of reducing trade imbalances with the rest of the world.

The president has this month been posting letters to roughly two dozen countries and the European Union that simply levied a tariff rate to be charged starting August 1.

Those countries generally faced tax rates on the goods close to the April 2 rates announced by the US president, whose rollout of historically high import taxes for the US caused financial markets to panic and led to Trump setting a 90-day negotiating period that expired July 9.

Trump also said he would "probably" announce tariffs on pharmaceutical drugs at the "end of the month".

The president said he would start out at a lower tariff rate and give companies a year to build domestic factories before they faced higher import tax rates. Trump said computer chips would face a similar style of tariffs. (AP) DIV DIV

Tariffs on smaller nations to be applied as a uniform import rate, with phased measures for drugs and semiconductor chips. The executive announced a uniform import tariff to be applied to goods from a broad set of smaller trading partners, mainly in Africa and the Caribbean, with notices issued setting an implementation date and reflecting previously announced import tax levels. Separately, planned tariffs on pharmaceuticals and semiconductor chips will start at a lower rate and include a one-year transition period to allow domestic production to be established before higher rates apply.
