This appears to be a measure to address the fentanyl issue manufactured in China, as he had warned. The White House emphasized that fentanyl is the leading cause of death for Americans aged 18 to 45, and most of its raw materials are imported from China. It also accused the Chinese Communist Party of funding companies that manufacture and export fentanyl.

President Trump had already imposed a 10% additional tariff on China since the 4th and signed an executive order to raise it to 20%. This measure aims to strengthen the response to China's drug problem and prevent dangerous substances like fentanyl from entering the United States. It is analyzed that this has a complex purpose of addressing both the fentanyl addiction problem in the U.S. and trade issues with China.

Officials from Canada and Mexico are lobbying the Trump administration to block the influx of fentanyl into the U.S. and are making efforts to strengthen border controls. Mexico is enhancing its cooperation by extraditing 29 drug suspects, including drug lord Rafael Caro Quintero, to the U.S. Additionally, Mexico's Deputy Minister of Economy mentioned the possibility of adopting further trade measures to reduce the influx of cheap goods from China, in addition to the tariffs imposed on imports recently.

Earlier this month, the U.S. stopped its tax exemption policy for packages under $800 to block the unchecked influx of fentanyl and its precursors through airports and borders. However, this has led to a backlog of goods, and the U.S. Customs and Border Protection decided to suspend the stop order until more effective control measures are established.

These series of measures show that the efforts and cooperation of various countries to block the influx of fentanyl into the U.S. are more important than ever. In particular, the Trump administration's suspension of the tax exemption is largely aimed at Chinese online e-commerce companies like AliExpress and Temu.

According to Reuters, since the exemption amount was raised from $200 to $800 in 2015, the scale of small goods exports to the U.S. has significantly expanded, and it is estimated that in 2023, China's small goods exports will reach $4.7 billion.

On the 7th, the Trump administration decided to temporarily suspend the withdrawal of the minimum threshold exemption, but the frontline borders and logistics sites are in a state of emergency. According to CNN, the withdrawal of the minimum threshold exemption means that orders from China will undergo stricter inspections by Customs and Border Protection (CBP), and the U.S. Postal Service (USPS) has temporarily suspended parcel deliveries from China.

The New York Times (NYT) reported that USPS did not officially explain the relationship between the temporary suspension of parcel services and the Trump executive order, but stated that it would remain suspended until further instructions are given. Accordingly, individual parcels must include detailed information about the items being shipped, applicable tariff codes, and whether the tariffs have been paid.

These measures are expected to be an important milestone not only in blocking the influx of fentanyl into the U.S. but also in resolving trade conflicts with China.
