What a temperature-controlled process includes
Where controls are required, confirm the temperature range, packaging, transit duration, monitoring and response to excursions. A cold pack alone is not proof of a controlled process.
Questions for the supplier
- What conditions are supported for this material?

- How are delays and hot-weather routes handled?
- What should the buyer do about an unexpected arrival condition?
No universal rule
Requirements can vary by material, dry or liquid state and packaging. Confirm them before ordering rather than assuming every product needs the same treatment.
