This executive order implements the general terms of the United States of America and the United Kingdom of Great Britain and Northern Ireland Economic Prosperity Deal, which provides American companies access to British markets for beef, ethanol and certain other agricultural exports. It creates an annual quota of 100,000 vehicles for the United Kingdom to export to the United States at a 10% tariff rate, as well as a 10% tariff rate on automotive parts. It also provides for tariff rate quotas for the United Kingdom at most-favored-nation rates for its steel and aluminum products, conditioned upon the commitment of the United Kingdom’s meeting American requirements on security of supply chains of steel and aluminum products intended for export to the United States.
