Reefer Containers for Pharma and Food: Temperature-Controlled Shipping from India to the USA
By Kesh, Ocean Freight Specialist, Atmavaan · Published October 2026
One temperature slip can ruin a container of vaccines or frozen shrimp. Reefer container shipping is the heart of cold chain logistics, and holding the right temperature from factory to door protects both your cargo and your compliance.

What Is a Reefer Container?
A reefer container is a refrigerated container with insulated walls, a cooling unit and sensors. It actively controls temperature, and often humidity and ventilation. Most reefers hold a set temperature between about -30°C and +30°C.
Cargo type | Typical set-point |
Vaccines and biologics | +2°C to +8°C |
Room-temperature medicines | +15°C to +25°C |
Chilled meat and dairy | -1°C to +4°C |
Frozen meat and seafood | -18°C or colder |
Fresh fruit and vegetables | 0°C to +13°C |
Always follow the set-point and tolerance on your product specification.
Reefer Loading Basics
Pre-cool the cargo, not the empty container, unless you load through a sealed cold-chain dock. Otherwise warm air enters and condensation forms inside.
Load below the red line and keep the floor channels clear so cold air circulates.
Keep the unit powered at every stage: factory, truck, terminal and vessel.
A reefer cargo guide from insurer Steamship Mutual notes that most reefer claims come from wrong settings, poor airflow or power loss, all largely preventable.
What Your Forwarder Needs at Booking
Commodity, HS code, set-point and allowed tolerance
Ventilation and humidity settings
Confirmation that the cargo is pre-cooled
Genset (power) needs for road legs
Data logger and real-time tracking requirements
Permits and certificates, such as pharma or food-safety documents
Shipping Reefers from India to the USA
Indian companies supplied 47% of US generic prescriptions in 2025, and India is the top shrimp supplier to the US. The main reefer gateways are Nhava Sheva and Mundra for pharma and processed food, Chennai for south India, and Kochi and Visakhapatnam for seafood. Check sailings with our vessel schedule tools.
Food: FDA Prior Notice before arrival and a registered food facility
Medicines: FDA registration and drug listing for the manufacturer
All ocean cargo: ISF filed at least 24 hours before loading
Confirm product-specific rules with your customs broker, and estimate duty with the Atmavaan Tariff Simulator.
Protecting Reefer Cargo in the Last Mile
The last mile, from US port to consignee, is where the cold chain most often breaks. A clip-on genset powers the reefer during road delivery, so confirm fuel, book delivery slots early, make sure the consignee is ready to unload, and record the temperature on arrival. Pharma loads need these records for audits. Follow every move with Atmavaan Container Tracking. Trucking from Mexico or Canada? See our cross-border trucking checklist.
