The shippedVia field on a ChainOfCustody completes the shipment record alongside trackingNumber. Regulatory reviewers and labs need to know which carrier handled the cooler in case a shipment is delayed, lost, or arrives in unexpected condition. Common values include overnight courier names, local courier services, or "hand delivery" when a technician personally delivers the cooler. Record the actual carrier name, not just "overnight," for maximum traceability.
