How the ESHUN → USPS handoff works

Follow the parcel across both networks without waiting on asynchronous webhooks or losing visibility at the handoff boundary.

1. ESHUN origin warehouse receipt
ESHUN receives the parcel at its Chinese consolidation hub, weighs the package, and assigns a ZES/ESHUN waybill.
2. Cross-border trunk linehaul & customs clearance
The shipment crosses the border via air or overland trunk linehaul and clears import customs.
3. Local courier / postal handoff
The cleared parcel transfers to the destination postal service or regional courier for final delivery.
ESHUN query
GET /v1/track/{number}?carrier=eshun
Normalized events
