Shipping frozen goods requires constant temperature control to maintain product quality and safety. While normal rail freight is often the preferred method for long-haul transportation, using intermodal reefer containers offers a compelling alternative.
In this blog post, we’ll explore the top benefits of shipping frozen goods by intermodal freight, focusing on efficiency, cost-effectiveness, and environmental sustainability. If you’re moving temperature-sensitive products, this is your must-read guide to shipping frozen goods the smart way.
What Are Intermodal Reefers?
Refrigerated containers—commonly known as intermodal reefers—are designed specifically for shipping frozen goods and other temperature-sensitive cargo. These containers are equipped with advanced refrigeration units that maintain a constant internal temperature, powered by the rail network’s electrical systems.
Used across industries like food and beverage, pharmaceuticals, and chemicals, intermodal reefers are essential for transporting perishable items such as seafood, meat, dairy products, and frozen produce. By keeping the temperature within a safe range, these containers ensure frozen goods arrive in perfect condition.
Common Misconceptions About Shipping Frozen Goods by Rail
A common myth is that rail freight is too slow or unreliable for shipping frozen goods. This couldn’t be further from the truth. In fact, shipping frozen goods by intermodal rail is one of the fastest-growing methods in Canada.
Understanding how reefer intermodal freight works helps businesses optimize for cost and quality control.
Types of Shippers in Frozen Goods Transportation
When it comes to shipping frozen goods, there are three main types of shippers:
- Load and Cool: Products are loaded fresh and cooled during transit.
- Load and Go: Frozen goods are loaded, and the reefer reaches optimal temperature en route.
- Wait for Temperature: Products are loaded only after the reefer hits the exact required temperature.
Each method impacts transit timing and pricing. Shippers who choose “Wait for Temperature” often incur driver wait fees—but get precise temperature control before loading.
How Intermodal Reefers Work
Refrigeration units in these containers function using a compressor and refrigerant loop to extract heat. The system constantly monitors and adjusts cooling levels to maintain the set temperature.
This level of control is vital for shipping frozen goods safely across long distances without spoilage or quality loss.
Real-World Uses of Intermodal Reefers for Shipping Frozen Goods
1. Seafood Restaurants
Fresh fish doesn’t stay fresh without precise cooling. Intermodal reefers allow seafood distributors to move frozen goods from the coast to inland restaurants with confidence.
2. Grocery Delivery Services
Retailers rely on refrigerated transport to move frozen products directly to distribution centers or homes without compromising quality.
3. Pharmaceutical Companies
Many medications must be kept within strict temperature ranges. Intermodal reefers help meet compliance and safety standards when shipping frozen goods like vaccines or biologics.
4. Fine Art Galleries
Art can be considered a temperature-sensitive item. Reefers maintain stable environments to protect pieces from heat or humidity during transport.
Benefits of Shipping Frozen Goods by Intermodal Reefer
✅ Cost Efficiency – Intermodal shipping is often more affordable than full-truckload reefer transport, especially over long distances.
✅ Environmental Advantage – Trains emit up to 75% less greenhouse gas than trucks per ton-mile, making intermodal a greener option for shipping frozen goods.
✅ Secure and Reliable – Rail yards offer higher security, and less handling reduces the risk of product damage or theft.
✅ Scalable Logistics – Whether shipping frozen goods seasonally or year-round, intermodal solutions adapt to your business’s volume.
✅ Final-Mile Flexibility – With integrated drayage, intermodal reefer freight ensures your goods make it all the way to their final destination, cold and intact.
Key Considerations for Reefer Shipping Logistics
Keep in mind that most rail carriers require reefer containers to be emptied and returned within 24 hours of unloading. This might mean scheduling weekend deliveries to avoid penalties.
If you’re planning to start or scale your shipping of frozen goods, knowing these rules can help you stay compliant and avoid unnecessary fees.
Conclusion: Keep It Cool, Ship It Smart
Shipping frozen goods isn’t just about keeping things cold—it’s about protecting your brand, ensuring customer satisfaction, and maintaining product quality from dock to door.
As demand for refrigerated shipping grows, intermodal reefer freight provides a scalable, reliable, and sustainable solution for businesses across North America.
