The American postal service (USPS) says that it temporarily ceased to accept the plots of continental China and Hong Kong.
The letters will not be affected by the suspension, according to A declaration on the company’s website.
The USPS said that the suspension will be in place “until further notice” and has not offered a reason for the decision.
This occurs after US President Donald Trump imposed an additional 10% rate on all goods imported into the United States of China.
Trump’s decree eliminated an exemption which allowed goods worth $ 800 (£ 641) or less to enter the United States without having to pay rights or certain taxes.
The so -called “minimis” tax escape has been faced with a meticulous examination in recent years while Chinese electronic commerce giants like Shein and Temu to reach millions of American customers.
In response China said it would implement prices on certain American imports.
From February 10, coal and liquefied natural gas products (LNG) will face a 15%tax. Raw oil, agricultural machines and large motor cars will be subjected at a rate of 10%.
President Trump is expected to speak to his Chinese counterpart Xi Jinping in the coming days.
“Trump’s tariff changes are particularly clear if the goods were previously dispatched via electronic commerce directly from China to the United States,” said Deborah Elms, a sales expert.
Almost half of all the plots entering the United States under Minmimis were sent from China, according to a report in 2023 of the US Congress Committee on China.
US officials have stressed that the large flow of plots entering the country through this exemption has made them more and more difficult to detect them for possible illegal goods.
The BBC contacted USPS to request more details on the decision.
