The tariff on small packages worth up to $800 (£606) have been cut from 120% to 54%, according to a White House statement.
BBC News reports that President Donald Trump reduced the tariff on small parcels sent from mainland China and Hong Kong to the U.S., shortly after the world's two biggest economies said they would cut levies on each other's goods for 90 days.
The flat fee per parcel will remain at $100, while a $200 charge due to apply from June 1 has been cancelled.
The duty-free rule, known as de minimis, which effectively exempted all packages of a value below $800 from both tariffs and extra customs scrutiny, was cancelled by the Trump administration May 2.
De minimis imports have surged dramatically since 2018, with China accounting for nearly two-thirds of 2.3 billion duty-free shipments between 2018 and 2021, and Chinese e-commerce giants Temu and Shein combining to account for 30% of 2022's total alone, according to the U.S. International Trade Commission.
