The United States Postal Service on Wednesday said it would continue to accept packages from China and Hong Kong, reversing a decision to temporarily halt those deliveries after an order by President Trump took effect that ended duty-free handling of many smaller parcels. Mr. Trump ordered on Saturday that all goods leaving China starting on Tuesday must follow the rules for higher-value shipments. Until the change, parcels worth up to $800 apiece were not required to include detailed information on their contents and were not subject to tariffs. A spokesman for the postal service said that as of Wednesday, it “will continue accepting all international inbound mail and packages from China and Hong Kong Posts. The USPS and Customs and Border Protection are working closely together to implement an efficient collection mechanism for the new China tariffs to ensure the least disruption to package delivery.”

The U.S. Postal Service is reversing course a day after placing a ban on all inbound packages from China and Hong Kong. The post office had announced Tuesday that it would no longer accept parcels from the China and Hong Kong after the U.S. imposed an additional 10% tariff on Chinese goods and ended a customs exception that allowed small value parcels to enter the U.S. without paying tax. The Postal Service reversed course Wednesday but gave no reason. It said it would work with Customs and Border Protection to implement a collection process for the new China tariffs to avoid delivery disruptions.

The reversal came less than 24 hours after the agency temporarily suspended international package acceptance of inbound parcels from China and Hong Kong Posts "until further notice." The Tuesday package suspension announcement came as China issued retaliatory tariffs on select American imports. The Chinese government said it would take "necessary countermeasures" in response to President Donald Trump’s executive order imposing a 10% tariff on Chinese imports to address what the White House says is the synthetic opioid supply chain in China. Trump temporarily paused planned tariffs on Mexico and Canada for 30 days to give both nations time to reach a deal with the U.S. to better secure its northern and southern borders.
