Shipping perishable goods successfully demands a continuous cold chain.

Clearly mark boxes as “Perishable” and specify the required temperature so carriers handle them as temperature-controlled freight.
Yes, Frozen food can in many cases be shipped with dry ice by air, but dry ice is regulated as a dangerous good. Airlines have limits on how much dry ice is allowed per package and per shipment, and labels must show the net weight of dry ice and UN1845 markings. Our compliance team recommends checking carrier and destination rules in advance and combining dry ice with insulated packaging to keep reefer cargo at temperature while staying within dry‑ice limits.
Standard cargo policies may Exclude coverage for temperature-related loss on chilled food and Frozen goods.

Most Chilled food should stay between 0–4°C, while many frozen goods products must remain at −18°C or colder. Exact ranges depend on the product type and local regulations.

You can sometimes mix Fresh produce and frozen goods in the same load, but only if your container or vehicle can maintain separate temperature zones. Fresh produce typically needs temperatures above freezing, while frozen food must stay well below zero. If only one temperature setpoint is available, best practice is separating them into different Reefer cargo shipments to avoid freezing Fresh produce or partially thawing frozen items.
Fresh and frozen food must be maintained at specific temperature ranges throughout the air freight process to ensure product integrity. Proper insulation and refrigeration units are essential during transport to prevent spoilage or thawing. Additionally, swift loading and unloading are critical to minimize temperature fluctuations.
Shipments of fresh and frozen food must comply with USDA and FDA regulations, including obtaining necessary import permits and adhering to food safety standards. Documentation such as health certificates, import permits, and compliance with specific labeling requirements are essential for customs clearance in the United States.
