Shipping Refrigerated Food from Charleston to Portland via Ocean Freight

Moving fresh produce successfully necessitates a continuous cold chain. Use thermal containers with the right amount of gel packs for refrigerated food or dry ice for Frozen food, pre‑chill products before packing, and choose a expedited service. Clearly mark boxes as “Perishable” and specify the required temperature so carriers handle them as temperature-controlled freight.

Yes, frozen goods can often be shipped with dry ice by air, but dry ice is regulated as a dangerous good. Airlines impose 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 limit coverage for temperature-related loss on fresh food and frozen food. Insurance specialists generally recommend arranging a policy that specifically covers temperature deviation and spoilage, and declaring the full value of your refrigerated food shipment. Keep packing records and temperature logs; insurers often require proof that adequate insulation was used before honoring claims.

Most refrigerated food 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 check 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 fresh food and Frozen food in the same load, but only if your container or vehicle can maintain separate temperature zones. Chilled food typically needs temperatures above freezing, while Frozen goods must stay well below zero. If only one temperature setpoint is available, most logistics providers recommend separating them into different Reefer cargo shipments to avoid freezing Fresh produce or partially thawing frozen items.

It is essential to maintain appropriate temperature controls throughout the journey, using refrigerated containers for fresh produce and frozen food. Proper insulation and monitoring systems should be in place to prevent temperature fluctuations that could compromise product quality.

Both Charleston and Portland operate under U.S. regulations, which require that fresh and frozen food products comply with the Food and Drug Administration (FDA) guidelines. Proper documentation, including bills of lading and any necessary health certificates, must be prepared to ensure compliance with safety standards.
