A business carrying chilled freight works under two separate sets of rules. The Road Transport Regulation sets who may carry what and in what scope; food law sets the conditions the load travels in. One being in order does not complete the other.

What each licence covers

K1 is issued to those hauling goods commercially within Turkey. C2 covers commercial goods haulage both internationally and domestically. Those who carry only goods related to their own main business, without commercial haulage, have separate licences: K2 domestically, C1 internationally and domestically.

When haulage is subcontracted, the licence sits with the subcontractor. Write into the contract the carrier's licence status, who measures and shares records, and who reports an excursion; if an Isotec container travels in a panel van, the vehicle's scope is judged by the transport licence and the container's condition by the temperature the product requires.
