US indefinitely suspends de minimis duty exemption for low-value mail imports worth $800 or less

A Federal Register notice announces the indefinite suspension of the de minimis exemption for mail shipments valued at $800 or less. Low-value imports that previously avoided duties and simplified customs handling will now face new postal informal entry requirements.

The move could significantly raise costs and compliance burdens for cross-border ecommerce sellers, marketplaces, postal operators, and consumers. It signals a broader shift toward tighter scrutiny of low-value imports and may accelerate moves toward domestic warehousing, formal customs brokerage, or supply-chain restructuring.
