What does Controlled room temperature (CRT) mean in logistics?

Short answer

A controlled ambient range for products that must not overheat or freeze, commonly 15 °C to 25 °C in pharmaceutical practice, with the exact limits taken from the product label.

Many medicines in India are labelled "store below 25 °C" or "store below 30 °C". In Indian summers an ordinary closed truck can exceed these limits, so CRT pharma often moves in temperature-controlled vehicles. Ask our desk how this applies to your consignment.
