Shipping Refrigerated Food from Shenzhen to Portland via Ocean Freight

Moving fresh produce successfully necessitates 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 expedited service. Clearly mark boxes as “Perishable” and specify the required temperature so carriers handle them as temperature-controlled freight.

Yes, Frozen food 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. 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 limit coverage for temperature-related loss on fresh food and frozen food. 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 Proper packaging 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 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 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, most logistics providers recommend separating them into different Reefer cargo shipments to avoid freezing perishable goods or partially thawing frozen items.

Fresh and frozen food requires temperature-controlled containers to maintain appropriate temperatures throughout the journey. It is crucial to monitor and manage the refrigeration systems to prevent spoilage during the ocean freight. Additionally, proper packaging is essential to ensure the integrity of the products and compliance with health regulations.

Shipments of fresh and frozen food must comply with FDA regulations, which include obtaining necessary permits and ensuring products meet safety standards. Importers must provide detailed documentation, including a bill of lading, commercial invoice, and any required inspection certificates, to facilitate customs clearance at the Port of Portland.
