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.

Chinese sellers應對策略迅速分化。部分商戶開始轉向海外倉模式，將貨物提前囤積至美國境內倉庫以規(guī)避清關風險。某跨境電商平臺高管透露，其洛杉磯海外倉的租賃咨詢量在政策波動期間暴漲300%，雖然倉儲成本增加20%，但相比關稅不確定性仍是更優(yōu)選擇。這種轉變恰好契合中國海關總署的最新政策——February 6公布的跨境電商Export DrawbackThe new regulations clearly state that goods in overseas warehouses can apply for tax rebates upon leaving the country, injecting a shot in the arm for the model transformation.

The Trump administrations policy搖擺引發(fā)多方博弈。暫停豁免被解讀為給CBP爭取系統(tǒng)升級時間的權宜之計，但其同步宣布的對華10%全面關稅仍如達摩克利斯之劍高懸。摩根大通供應鏈金融團隊分析，若豁免政策最終取消，單個小額包裹的清關成本將增加5-8美元，迫使客單價低于15美元的商品退出美國市場。這種沖擊已反映在資本市場，拼多多美股股價在政策波動期間振幅達12%，Shein估值模型中被加入15%的監(jiān)管風險折價。
