The Biden administration's plans to restrict the de minimis trade law loophole could impact the prices of Shein and Temu products. This loophole allows items under $800 to bypass tariffs. Retail experts estimate that prices could rise by at least 20%, narrowing the gap between these retailers and competitors. The de minimis exemption has been under scrutiny for enabling these e-tailers to avoid U.S. customs duties, and lawmakers are pushing for reform. Shein and Temu dispute that their business models rely on this exemption.
