Abstract: A transport method for temperature-controlled products, a transport container, a conditioning device or filling device, and a control software are proposed. In a method for transporting temperature-controlled products, a transport container containing a product having a product weight is supplied with a preconditioned thermal mass before the start of transport, the quantity of the thermal mass supplied being computationally calculated in advance on the basis of thermodynamically and/or logistically relevant data such as product weight and/or the starting location and destination and/or the estimated transport time and/or weather data at the starting location and/or at the destination and/or between the starting location and destination and/or a temperature range to be maintained.
