One record
The custody record travels with the shipment. Every handoff is counted, timed and signed. The operator for each leg is named on it.
Service
You already know how a dose moves: shipper to forwarder, forwarder to air operator, air operator to courier, courier to whoever is at the dock. Every handoff is a new company, a new set of shipping papers and a new phone number, and accountability for the dose gets thinner at each one. Centragen runs the whole lane as one chain of custody, so the ground handler, the air operator and the final-mile courier work from the same record, the same receiving window and the same accountable contact.

The custody record travels with the shipment. Every handoff is counted, timed and signed. The operator for each leg is named on it.
Every lane is built around your receiving window, not a vehicle's schedule.
Shipment questions, requirement changes, exceptions and service concerns stay in one thread with one accountable contact.
