50% copper tariff in effect by August 1?

On July 10, President Trump announced that the United States would apply a 50% tariff to all copper imports beginning August 1 (see: https://www.bloomberg.com/news/articles/2025-07-10/trump-says-50-tariff-on-copper-imports-to-take-effect-august-1). This market will resolve to “Yes” if a general 50% tariff on copper imports into the United States goes into effect for any amount of time by August 1, 2025, 11:59 PM ET. Otherwise, this market will resolve to “No”. For the purpose of this market, "goes into effect" means the start date for the tariffs must have passed without being further delayed or suspended. A general tariff that includes item or country specific exceptions will still qualify, as long as a policy of a general 50% tariff on copper imports into the United States goes into effect. Only tariffs specifically targeting copper will qualify. For example, a new global tariff (tariffs on all imports into the U.S.) will not count toward this market's resolution. This market's primary resolution source will be official information from the Trump administration; however, a consensus of credible information will also be used.
