Classification by National Standard Temperature Grades (GB29753-2013)
Classes A–F (Perishable food transport): Class A (12°C to 0°C; for produce, dairy); Class B (12°C to -10°C); Class C (12°C to -20°C); Class D (≤0°C; for chilled fresh meat, poultry, eggs); Class E (≤-10°C); Class F (≤-20°C; for frozen meat, ice cream).
Classes G–H (Biological product transport): Class G (8°C to 2°C; requires GSP certification; for vaccines, blood); Class H (≤-20°C; for high-value goods such as stem cells, plasma).
Classification by Refrigeration Method
Mechanical refrigerated trucks: Precise temperature control; the mainstream market type; suitable for long-haul trunk transport.
Eutectic plate refrigerated trucks: Can maintain temperature for 6–12 hours after pre-cooling; primarily used for short-distance urban distribution.
Liquid nitrogen/dry ice refrigerated trucks: Rapid cooling; suitable for high-value biological products or specialized transport scenarios.
Other Common Classifications
By chassis load capacity: Micro, small, medium, and large refrigerated trucks.
By cargo body structure: Van-style, box-type, and semi-trailer refrigerated trucks; suited for "last-mile" delivery, inter-city transport, and cross-provincial trunk transport, respectively.
