Chinese packages under $800 were exempt from tariffs due to the "de minimis" exemption, now ended under new U.S. rules that came into effect Tuesday.

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

However, on Tuesday new rules came into force which closed a loophole that allowed small packages worth $800 (£641) or less to be sent to the US without paying tax or fees. It was one of the measures announced by US President Donald Trump who imposed an additional 10% tariff on all goods imported to the US from China.
