18 hospitals, 50+ chains, one 4-hour cold-chain window: how TONGNIAN ships
The TONGNIAN delivery network now covers 18 hospitals and 50+ chains. Every program ships with specs and COA attached, matched to batch tier.
How the network operates. Programs ship on designed lanes, not ad-hoc couriers: Material moves on −20 °C and −80 °C dry-ice lanes (validated 60-day and 360-day windows). Finished goods move on 2–8 °C cold chain or cool-dry, with temperature logging on every leg. Inside the city, a 4-hour courier window moves time-critical freight: clinic session material and channel-trial sample kits.
Every destination receives the documentation set its market requires: COA, lane records, and the filing references that apply. Every vial scans back to its full chain, delivery leg included.
Program logistics are specified per lane — ask for the lane map on request.
