As he left office, former US president Donald Trump exempted the UAE from a 10 per cent tariff imposed by his administration in 2018 on metals imports, after the two countries agreed to a quota limiting the volume of aluminium imports from the Gulf nation.
The agreement stems from the two countries' national security and economic ties, Mr Trump said in a proclamation issued by the White House on January 20, prior to the inauguration of Joe Biden as the 46th US president.
"This measure is expected to allow imports of aluminium from the United Arab Emirates to remain close to historical levels without meaningful increases, thus making it more likely that domestic capacity utilisation will be reasonably commensurate with the target level recommended," Mr Trump said.
The ex-president eased the metals tariff he imposed in March 2018. The UAE is the third-largest aluminium exporter to the US and is home to Emirates Global Aluminium (EGA), which exports the metal globally and is the largest industrial company in the country outside the oil and gas sector.
The exemption will start on February 3, according to the proclamation.
Other countries that have also been excluded from the tariff include Argentina, Australia, Canada and Mexico.
Mr Trump said the measure "will provide effective, long-term alternative means to address the contribution of the United Arab Emirates to the threatened impairment to our national security by restraining aluminium article exports from the United Arab Emirates to the United States, limiting export surges by the United Arab Emirates, and discouraging excess aluminium capacity and excess aluminium production".
The agreement stems from the two countries mutual interests, according to the proclamation.
