US Trade envoy Jamieson Greer discussed new tariff measures on July 21 as the temporary 10% global levy is set to expire. Supported claims include a 25% duty on select Brazilian goods, a 50% levy on many Canadian products effective in 30 days, and a planned 100% tariff on imported generic drugs from August 2028. One claim regarding phased 100% and 200% drug tariffs is internally disputed within reporting.
