How the Yunda Express → Royal Mail handoff works

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

1. Domestic Chinese collection & export hub consolidation
Yunda collects the parcel from the Chinese factory or marketplace seller and routes it to its international export hub in Shanghai, Yiwu, or Shenzhen.
2. Air linehaul to London Heathrow (LHR)
Consolidated bags fly to London Heathrow, clear HMRC import customs, and are broken down at a Slough or Hayes customs warehouse.
3. Royal Mail or Evri final-mile induction
Parcels are injected into Royal Mail's Princess Royal / Midlands Super Hub (or Evri's Rugby hub) for UK doorstep delivery in 48 hours.
