Transport and routing32 / 35

Separate engine, refrigeration-unit and handling noise. Measure changes at the same delivery location to see what helps.

Do not add a fixed percentage to winter quantities. Measure dry-ice mass, vehicle environment and product temperature on comparable loads and routes.

In transit, meat must stay at or below 3 °C for offal and 7 °C for other meat; mince is limited to 2 °C and meat preparations to 4 °C. The temperature is reached before loading and held all the way.

By air, dry ice is dangerous goods under UN 1845. Carriers that accept it require a declaration, a Class 9 label, the net quantity and packaging that lets the gas escape.

On a short route a tube moves a specimen in seconds. Without a sponge insert hemolysis rises sharply, so each route and carrier needs its own approval.

At every handoff, record dispatch, wait and receipt times, responsible staff and product conditions.

Under time pressure, rely on product instructions, ready equipment and an assigned decision owner.

Power access, costs and product disposition may be unclear during a hold. Keep a timeline and confirm roles in writing.

Assess stop order with records, not assumptions. Track each stop, lid opening, wait, handover and temperature reading on one timeline.

Validate the last mile against product instructions, carrier and handover records. Measure route time, weather, stops and openings.

Personal medicine goes in the cabin with a prescription and its original pack, held at +2 to +8 °C door to door. A commercial consignment follows a separate route with a qualified container and airline cargo acceptance.

Match warehouse release and vehicle loading in one lot record, and measure dock waiting separately.

Validate the full shipment, including door-to-door waits, not just flight time. Check product, packout, carrier and dangerous-goods acceptance together.

Do not assume a fixed hold time. Define customs process, documents, monitoring and quality decisions in the shipment plan.

Measure actual elapsed time: use lane records to expose dwell at transfers, breaks and delivery.

The clock starts when the parcel is sealed. Packaging validation, waiting time at transfer hubs and the delivery record are the sender's responsibility, whatever the carrier's speed.
