President Donald Trump said Tuesday he’s imposing a new 50% tariff on all copper. However, it’s unclear when the new tariff would take effect.

President Donald Trump vowed to push forward with his aggressive tariff regime in the coming days, stressing he would not offer additional extensions on country-specific levies set to now hit in early August while indicating he could announce substantial new rates on imports of copper and pharmaceuticals.

Trump also said he would soon announce tariffs “at a very, very high rate, like 200%,” on pharmaceutical imports.
