Shipping Perishable Goods from Penang to Mexico City via Ocean Freight

Transporting perishable goods successfully demands 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 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 in many cases 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 restrict coverage for temperature-related loss on chilled food and Frozen goods. 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 Proper packaging was used before honoring claims.

Most chilled beverages 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 chilled 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, most logistics providers recommend separating them into different Reefer cargo shipments to avoid freezing perishable goods or partially thawing frozen items.

Fresh & Frozen Food requires temperature-controlled containers to maintain appropriate conditions throughout the journey. It is essential to monitor the refrigeration system and ensure proper loading techniques to minimize temperature fluctuations and prevent spoilage.

Regulatory requirements include obtaining necessary import permits from Mexico, ensuring compliance with food safety standards, and providing health certificates that confirm the freshness and safety of the products. Additionally, all shipments must adhere to customs documentation requirements for food products.
