**Introduction** Suspending the US de minimis rule would require many low-value imports that currently enter duty-free and with simplified procedures to go through normal customs processing. The likely consequences include higher consumer prices, more paperwork and delays at the border, heavier workloads for customs authorities, and changes to how e-commerce companies ship and store goods[1][2]. **Contextual background** De minimis thresholds are used by many countries to allow low-value shipments to enter duty-free and with simplified customs procedures. The purpose is to reduce administrative costs where the revenue collected would be minimal. In the United States, Section 321 of the Tariff Act of 1930 sets the de minimis threshold at US$800[3]. **Economic and trade effects** **1.** **Higher prices for consumers** If a de minimis rule is suspended, shipments that were previously duty-free would generally become subject to normal customs duties. Importers and online sellers would also face higher administrative and compliance costs. In competitive retail markets, these additional costs are often reflected in higher consumer prices[1][2]. Low-cost consumer goods sold through direct-to-consumer platforms would be particularly affected. **2.** **Increased** **administrative burden and potential delays** Without de minimis treatment, shipments must go through standard customs entry procedures. This requires more detailed documentation, formal duty assessment, and full processing. Customs authorities and logistics providers would need to manage a larger number of formal entries. Where parcel volumes are high, this can increase processing times and operational pressures, particularly during an adjustment period[1]. **3.** **Changes in e-commerce and logistics models** Many e-commerce firms rely on shipping individual parcels directly to consumers under de minimis rules. If these rules are suspended, firms may shift toward: * Importing goods in bulk and storing them in domestic warehouses before distribution; or * Consolidating shipments to reduce the number of customs entries. These adjustments can increase fixed costs, such as warehousing and inventory management, and may be more difficult for small businesses to manage[2]. **Conclusion** Suspending a de minimis rule would make small-parcel trade more costly and administratively complex. Goods that once entered duty-free with minimal paperwork would instead be subject to standard customs procedures, increasing both compliance costs and processing requirements. Consumers would likely face higher prices, while customs authorities and logistics providers would handle heavier workloads. Firms would respond by adjusting shipping and fulfilment strategies, often shifting toward bulk importation and domestic warehousing. Taken together, the effect would be a gradual move away from ultra-low-cost, direct-to-consumer parcel shipping toward more formal and structured import and distribution channels[1][2].
