Canada and Mexico managed to negotiate a month-long reprieve from 25% tariffs threatened by U.S. President Donald Trump.

The move will likely have an impact on e-commerce platforms like Shein and Temu, along with operators of drop shipping businesses.

The ban was implemented on Feb. 4 after President Donald Trump directed the United States to implement an additional 10% tariff on Chinese goods and ended a customs exception that allowed small value parcels to enter the U.S. without paying tax.
