Real customs fees for inbound international packages from legitimate carriers (USPS, FedEx, UPS, DHL, Canada Post) are collected through official carrier portals or at the time of delivery with a paper notice; no legitimate postal or customs authority solicits fee payment via an unsolicited email payment link. Distinct from package-customs-duty-phish (broader customs-duty vocabulary) — this signal specifically targets the \"held at customs / post office, pay fee to release\" narrative. Detection: package/parcel held at customs/post office + pay delivery fee/customs fee to release vocabulary + no List-Unsubscribe + no In-Reply-To + not protected sender. Trash score: +3.
