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 press release 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 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 (£ 474) 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.
“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.
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.
USPS did not immediately respond to a request for comments from the BBC.
