The new tariffs announced by President Trump in 2025 are set to go into effect primarily on August 7, 2025. This date was chosen to give Customs and Border Protection time to adjust to the new duties. Some exceptions apply, such as Canada's tariffs which started earlier on a Friday before August 7. Also, the higher China tariff rate is scheduled to take effect on August 12, 2025. The tariffs affect a broad range of U.S. trading partners with rates varying by country, ranging mostly from 10% to over 40%. For most countries not specifically mentioned, a baseline 10% tariff will be applied starting August 7. There have been some delays and adjustments to previous tariff deadline plans, such as delays from an initially anticipated date in July to August 1, then to August 7 for many countries.

In summary:

• Most new tariffs take effect on August 7, 2025.
• Canada’s tariffs started a few days before August 7.
• China’s higher tariff rate comes into effect on August 12, 2025.

This timetable marks the current implementation schedule as of August 2025.
