A duration printed on a container does not by itself show time remaining on this trip.

TİTCK's good distribution inspection form asks whether the maximum duration is marked on a medicinal cold-chain device.

That documentation requirement does not set one holding limit for every product and route.

Ask which test produced the duration

Look for the supplier report's method, load, ambient profile, endpoint and instrument.

Check field applicability

Compare product acceptance conditions, route, door activity and measurement uncertainty in your own qualification file.

Tying the figure on the box to the journey the product actually makes is where last-mile cold chain planning begins.

Do not assume a universal cabin hold time; record missing product evidence and refer disposition to an authorised person.
