A 10 percent tariff on all Chinese goods officially started at midnight Tuesday, adding another layer to the ongoing trade tensions between the U.S. and China. This move, announced over the weekend, is part of President Trump’s effort to push Beijing to take stronger action against fentanyl shipments entering the United States.

The new tariff piles on top of existing ones, with many Chinese products already facing levies of 10 or 25 percent. This latest increase will affect over $400 billion worth of goods Americans buy from China each year. While the president called it an “opening salvo,” it’s unclear whether further negotiations could lead to the removal of these tariffs.

Interestingly, plans to impose similar tariffs on Canada and Mexico were put on hold after talks resulted in a 30-day pause. Both countries committed to tightening their oversight of fentanyl and border security, avoiding what could have been a major trade conflict with two of America’s closest trading partners.

Trump mentioned he plans to speak with Chinese leader Xi Jinping soon, but details of the call remain unclear. Meanwhile, the executive order signed on Saturday also closed a loophole that allowed Chinese companies, like Shein and Temu, to ship goods directly to U.S. consumers without paying tariffs.

While the temporary deal with Canada and Mexico offers some relief, the situation highlights the ongoing unpredictability in global trade relations under the Trump administration. For now, the focus remains on whether China will respond to the pressure and how these tariffs might impact businesses and consumers on both sides of the Pacific.
