USPS customs charges: how postal shipments differ
Short answer
International mail clears under different procedures from express courier shipments. Postal items carry a flat postal handling charge rather than a commercial brokerage fee, and the de minimis rules for mail are handled separately from all other transport modes.
When duty is owed on a postal item, it is assessed on a Customs form attached to the package and collected on delivery, usually with a flat postal handling charge. There is no brokerage relationship, no advancement of funds, and no percentage-based disbursement — which is why postal charges are often smaller than courier charges on an equivalent parcel.
The trade-offs are speed and visibility. Postal clearance is slower and gives you much less information about where a shipment is or why it stopped. If something goes wrong there is no broker to call, and the resolution path runs through the postal service rather than a commercial customer service desk.
The regulatory position is worth noting too. When CBP made the de minimis suspension indefinite by regulation in June 2026, the rule covered merchandise arriving by every mode other than the international postal network; postal shipments continue under their own separate guidance. The practical effect for a recipient is the same — duty applies — but the procedures are not identical.
