when do the tariffs go into effect

The tariffs largely go into effect on August 7, 2025, at 12:01 a.m. eastern daylight time for many countries. For example, new tariffs of 10% or higher apply to goods from over 60 countries and the European Union starting August 7, with some countries facing specific rates like 15% for the EU, Japan, and South Korea, and 20% for Taiwan, Vietnam, and Bangladesh. Additionally, a 50% tariff on copper imports went into effect on August 1, 2025. A 25% additional tariff on imports from India goes into effect later on August 26, 2025. Some exceptions and variations exist depending on the country and product category, but August 7, 2025 is the main date for the new broad tariff implementation.
