Temperature-controlled shipping refers to the transportation of goods that require specific temperature ranges to maintain their quality and safety. This method is commonly used for perishable items such as food, pharmaceuticals, and certain chemicals. Specialized containers, often called refrigerated trucks or reefers, are equipped with cooling systems to ensure that the temperature remains consistent throughout the journey. This shipping process is crucial for preventing spoilage and ensuring that products arrive in optimal condition. Companies often use temperature monitoring devices to track conditions during transit, providing real-time data to ensure compliance with safety standards and regulations.
