Online retailers like Shein and Temu are facing hefty new import tariffs of up to 120% on many products, after the US government scrapped the de minimis rule, which had previously allowed parcels worth $800 (£601) from China and Hong Kong to enter the country duty-free.

Fast-fashion giant Shein Group Ltd. raised US prices of its products from dresses to kitchenware ahead of imminent tariffs on small parcels, in an early sign of the potential effect of the trade war on American consumers.
