How will Trump's new 10% global tariffs work and what's next?

Here is a 184-word summary of the article: President Trump has announced a new 10% global tariff on imports, set to take effect on September 1st. This tariff will apply to virtually all remaining imports from China that are not already subject to existing tariffs. The move comes amid ongoing trade tensions between the US and China. It is unclear how the new tariffs will be implemented or what the economic impact will be. Some analysts predict it could lead to higher consumer prices in the US. Meanwhile, the Supreme Court recently ruled that people can seek refunds for tariffs that were found to be unlawfully imposed. This decision raises questions about the potential for refunds related to President Trump's previous tariff increases. However, the process for obtaining refunds remains uncertain. Overall, the new tariffs and the Supreme Court ruling add further complexity to the evolving US trade policy landscape.
