US reinstates 10 percent supplemental tariffs on imports of Canadian-origin aluminium and Canada responds with proposed countermeasures on US-origin aluminium

On 6 August 2020, US President Trump signed a presidential proclamation reinstating supplemental tariffs on certain aluminium products from Canada, effective 16 August 2020. The 10 percent supplemental tariffs, which are based on Section 232 of the Trade Expansion Act of 1962, will be levied on non-alloyed unwrought aluminium (HTSUS subheading 7601.10) of Canadian origin. The proclamation also stated that the US will monitor for import surges of articles currently exempt from supplemental tariffs under previous proclamations.

On 7 August 2020, in response to the US’s action, Canada proposed proportionate countermeasures consisting of a 10 percent surtax on imports of a variety of raw aluminium and aluminium-containing US-origin products, which would take effect on 16 September 2020. Canada clarified in its announcement that it considers imports to be US-origin if they are eligible to be marked as goods of the US under applicable Canadian marking regulations. Also, the countermeasures would not apply to US-origin goods that are in transit to Canada on the effective date.

Canadian businesses and industry associations impacted by the proposed countermeasures may submit written comments to Finance Canada by 6 September 2020.
