Shipping Reefer Cargo from Shanghai to San Jose via Ocean Freight

Transporting Fresh food successfully Requires a continuous cold chain. Use Insulated packaging with the right amount of gel packs for Chilled food or dry ice for Frozen food, pre‑chill products before packing, and choose a time‑definite service. Clearly mark boxes as “Perishable” and specify the required temperature so carriers handle them as temperature-controlled freight.

Yes, frozen goods can Usually be shipped with dry ice by air, but dry ice is regulated as a dangerous good. Airlines Set 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. We recommend checking carrier and destination rules in advance and combining dry ice with insulated packaging to keep Frozen food at temperature while staying within dry‑ice limits.

Standard cargo policies may restrict coverage for temperature-related loss on Perishable goods and Frozen goods. We recommend arranging a policy that specifically covers temperature deviation and spoilage, and declaring the full value of your Reefer cargo. Keep packing records and temperature logs; insurers often require proof that adequate insulation was used before honoring claims.

Most chilled beverages should stay between 0–4°C, while many Frozen food products must remain at −18°C or colder. Exact ranges depend on the product type and local regulations. Always Confirm requirements for each item and specify the target range on booking instructions and labels so your Reefer cargo is set correctly.

You can sometimes mix chilled food and Frozen food 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 goods must stay well below zero. If only one temperature setpoint is available, We recommend separating them into different Reefer cargo shipments to avoid freezing perishable goods or partially thawing frozen items.

Fresh and frozen food must be kept at specific temperature ranges throughout the shipping process to maintain quality. Proper insulation and temperature-controlled containers are essential to prevent spoilage. Additionally, regular monitoring of temperature during transit is crucial to ensure compliance with safety standards.

Shipments of fresh and frozen food must comply with Costa Rican regulations, including obtaining health certificates from the Chinese authorities. Import permits may also be required, along with documentation proving the product's origin and adherence to safety standards to prevent the introduction of pests and diseases.
