Shipping Frozen Goods from Charleston to San Juan via Ocean Freight

Moving fresh produce successfully Requires a continuous cold chain. Use Insulated packaging with the right amount of gel packs for refrigerated food or dry ice for frozen goods, pre‑chill products before packing, and choose a Fast transit 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 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 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 goods. We 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 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 fresh food 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 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 Fresh produce or partially thawing frozen items.

Shipments of fresh and frozen food from Charleston to San Juan require compliance with U.S. Customs and Border Protection regulations, including a bill of lading, commercial invoice, and any applicable health certificates to ensure the products meet safety standards.

Seasonal considerations include monitoring temperature fluctuations and potential weather impacts during hurricane season, which runs from June to November, as well as ensuring proper refrigeration during warmer months to maintain the quality of chilled and frozen food.
