A Latin term that’s been little-known outside the world of customs brokers has suddenly become the stuff of headlines. Along with imposing new 10% tariffs on all Chinese imports as of Feb. 4, US President Donald Trump suspended his country’s special rules for “de minimis” merchandise from China and Hong Kong.

Shein and Temu shifted more of their orders to be fulfilled in the US ahead of de minimis changes.

President Donald Trump’s sweeping tariff threats have been touch and go. As it stands currently, the 25 percent tax on goods from Mexico and Canada is on ice for a month, but a 10 percent tariff on Chinese goods is set to take effect on Tuesday, via an executive order of questionable legality.
