Shipping Chilled Food from Mexico City to Boston via Ocean Freight

Moving fresh produce successfully demands a continuous cold chain. Use thermal containers with the right amount of gel packs for refrigerated food or dry ice for frozen goods, 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 Reefer cargo.

Yes, frozen goods can often 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 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 goods products must remain at −18°C or colder. Exact ranges depend on the product type and local regulations. Always verify 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 goods 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, best practice is separating them into different temperature-controlled shipments to avoid freezing perishable goods or partially thawing frozen items.

Fresh and frozen food must be transported in temperature-controlled containers to maintain appropriate temperatures throughout the journey. It is essential to monitor the refrigeration units continuously to prevent spoilage during the ocean freight segment of the route.

Shipments of fresh and frozen food require compliance with both U.S. Food and Drug Administration (FDA) regulations and U.S. Department of Agriculture (USDA) standards. Importers must provide required documentation, including a phytosanitary certificate for produce and ensure that all products meet labeling and safety standards before entering the U.S.
