Customers of some e-commerce giants like Amazon, Shein and Temu are already feeling the effects of the impending closure of a trade loophole by the Trump administration. The "de minimis" exemption that allows packages under $800 to come into the U.

The days of getting a $20 table or a $10 dress from SHEIN or Temu could be coming to an end. Beginning May 2, Americans will start paying import duties of up to 145 percent on their orders from China as President Donald Trump gets rid of a loophole that made low-value packages coming from China exempt from tariffs.
