Inside the warehouses of the US Customs and Border Protection (CBP), millions of small - value parcels from China are piled up like mountains, a scene that vividly depicts the sharp turn of the Trump administrations tariff policy. From signing an executive order on February 1 to cancel the tariff exemption for cross - border parcels worth less than $800, to urgently suspending the new regulation on February 7, the policy reversal within just seven days not only led to logistics paralysis but also exposed the deep - seated contradictions in the US trade regulatory system. According to CBP internal documents, as of February 6, the total number of backlogged parcels at major US ports exceeded 1.5 million. The X - ray inspection equipment at the Los Angeles Customs malfunctioned due to over - operation, forcing the activation of manual sorting channels.

The core of this storm points directly to the de minimis tariff exemption system—a decades-old policy that allows small-value goods to bypass formal customs declarations, supporting platforms like Temu, Shein, and AliExpress.Cross-border E-commerceThe inadequacy of regulatory capabilities was fully exposed in this crisis. A CBP official anonymously revealed that the existing system can only handle the declaration needs of 3 million parcels per day, while the daily declaration volume suddenly increased to 5 million after the implementation of the new regulation. Whats more difficult is that about 35% of cross - border parcels lack compliant electronic data and require manual data entry, which is a disaster for the customs team that is already 15% understaffed due to heavy border control tasks. James Huang, legal counsel of the International Freight Association, warned: This is not a simple policy adjustment but an extreme stress test of the entire trade infrastructure.,Air TransportationThe response strategies of Chinese sellers have quickly diverged. Some merchants have started to shift to the overseas warehouse model, stockpiling goods in advance in warehouses within the United States to avoid customs clearance risks. A senior executive of a cross - border e - commerce platform revealed that the rental consultation volume of its Los Angeles overseas warehouse skyrocketed by 300% during the policy fluctuations. Although the warehousing cost increased by 20%, it is still a better choice compared to the tariff uncertainty. This shift coincides exactly with the latest policy of the General Administration of Customs of China - the new cross - border e - commerce regulation announced on February 6 clearly states that goods in overseas warehouses can apply for tax rebates upon departure, injecting a shot in the arm for the model transformation. A leading overseas warehouse service enterprise estimates that if fully converted to the pre - placed warehouse model, the average logistics time of Chinese sellers may be shortened by 3 - 5 days.

The limitations of regulatory capacity have been fully exposed in this crisis. CBP officials anonymously revealed that the current system can only handle 3 million parcel declarations per day, while the new regulations have caused daily declarations to surge to 5 million.
