The world shipping market is increasing, so the efficient and reliable transport of goods is important for businesses in different industries. With the use of advanced technologies, courier services are constantly struggling to provide solutions for international shipping through which sensitive goods can be shipped reliably in the best possible condition. This includes temperature-controlled solutions.
In this article, we will explore what temperature-controlled shipping is, the regulations related, and why it is important.
What Is Temperature−Controlled Shipping?
Temperature-controlled shipping, or cold chain logistics, is an important part of modern-day supply chains. This shipping method ensures that the temperature remains the same throughout the supply chain to protect the quality and safety of sensitive products during transit.
The cold chain logistics are important for certain food products, medicines, vaccines, flowers, and other perishable goods. If the temperature isn’t taken care of for these products, they can result in losing their efficacy. For example, this can lead to serious health issues when ineffective vaccines are consumed.
Carriers of temperature-controlled shipments make sure that the temperature requirements are well taken care of throughout the whole shipping procedure. The guidelines are often printed and are conveyed to all the parties involved in this temperature-controlled shipping.
Moreover, following the guidelines strictly minimizes product wastage, which reduces economic loss.
Types of Temperature-Controlled Shipping
There are many types of temperature-controlled freight options, which include:
Refrigerated Vehicles
Refrigerated vehicles are regular vehicles that have temperature-controlled cargo compartments. These closed vehicles, such as trucks or vans with refrigeration units, are powered by the vehicle’s engine supply.
For items that need to be kept ultra-frozen, some shipping companies use liquid nitrogen technology, which maintains a temperature of -196°C (-321°F).
Passive shipping container
They are shipping boxes with proper insulation, gel packs, or dry ice to maintain temperature. These containers may be kept inside temperature-controlled vehicles for an extra layer of protection.
Active shipping container
Active shipping containers are similar to passive ones, but these are much larger. Due to their size, they are commonly used in sea freight and air freight. The refrigeration unit of these containers is very powerful and it is powered by the ship’s or plane’s power supply. Sometimes the active shipping container has its own batteries that provide power to it.
Temperature-Controlled air freight
There are mainly two types of temperature-controlled air freight: commercial airlines and special cargo airlines. Both use specialized containers and handling procedures to maintain required temperatures.
Chilled, Frozen, and Deep-Frozen Shipping
According to the shipping temperatures, there are:
-
Chilled Shipping – +2°C to +8°C
-
Frozen Shipping – −20°C to −30°C
-
Deep-Frozen Shipping – below −30°C
Chilled shipping is commonly used for fresh goods such as dairy, vegetables, or flowers. Frozen shipping applies to ice creams or frozen food. Deep-frozen shipping is essential for highly sensitive products such as stem cells, genetic materials, vaccines, and other biotech samples.
Because thawing can ruin these products, they require reliable and delicate temperature-controlled containers and vehicles to ensure stability during handling and transfers.
Maintaining such extreme cold conditions demands specialized refrigeration technologies and continuous monitoring. These quality assurance measures give businesses confidence that their high-value goods will arrive intact.
Temperature−Controlled Shipping Tools
We have listed below a few of the settings that help businesses in transporting their temperature-controlled items safely without the fear of spoilage.
Dry Ice
Dry ice is frequently used in temperature-controlled shipping. It is also known as solid carbon dioxide or solid CO2. Dry ice sublimates directly from solid to gas and maintains extreme temperatures. It is more commonly used in the pharmaceutical sector and for the transfer of biological samples, such as the transportation of embryos for IVF.
Gel Packs
Gel packs are reusable for temperature-controlled shipments. These are filled with non-toxic gel and can be placed with products to help them maintain desirable temperature ranges.
Specimen Kits
Specimen kits are designed for laboratory settings. They usually have temperature monitors and shock-absorbing components for safe travel. These settings are used to maintain the quality of medicines, vaccines, biological specimens, and diagnostic materials during transportation.
Drum Heaters and Blankets
When shipping bulk materials in drums like oil or chemicals, a stable temperature is critical. And insulating blankets and drum heaters are used for this purpose. Drum heaters apply direct heat to the drum’s surface so there is an even and consistent temperature inside.
Styrofoam Coolers
In temperature-controlled shipping, styrofoam coolers provide double-layer insulation. They are lightweight and cost-effective. Styrofoam coolers are often used in short-distance shipping, as they can keep the products cool or frozen for a very limited time. That is why these are best for transportation between the retailer and consumer deliveries.
Rules and Regulations of Temperature−Controlled Shipping
Temperature-controlled freight carriers must be aware of the regulations and international standards required for cold chain logistics. It is important that these regulations are well taken care of so that the cold chain transportation isn’t compromised. A few of these regulations include the following:
Good Distribution Practices (GDP):
GDP guidelines are often adapted from international standards of shipping and are the basis of cold chain logistics for healthcare and pharma supplies. These regulations cover the storage, transportation, and distribution of temperature-sensitive items.
Food Safety Modernization Act (FSMA):
The Food Safety Modernization Act works in the United States. FSMA focuses on the safe transportation of food items, which particularly includes temperature-sensitive products. It demands proper temperature control and keeps a record. It also makes sure that proper sanitation practices are being implemented.
International Air Transport Association (IATA):
IATA provides specific guidelines for air transportation of perishable goods, pharmaceutical products, and other temperature-sensitive cargo items.
Moreover, parties involved in the temperature-controlled shipping process must know the regulations provided by the following authorities:
-
European Union
-
World Health Organisation
-
Parenteral Drug Association
-
Pharmacopeia
Conclusion
The world has become a global village, and goods are often transferred from one corner of the world to another. And maintaining the quality of these goods is important. This is when temperature-controlled shipping becomes a necessary solution. This shipping solution makes sure that your favourite food item, important vaccine, and sensitive specimen for research reach you in the best possible condition.
Frequently Asked Questions (FAQs)
What is a temperature-controlled item?
Many food items, such as dairy products, meat, frozen meals, etc., and different pharmaceutical products that need safe transfer without spoilage are called temperature-controlled items. Transportation of these products requires proper refrigerated tools to maintain a certain temperature.
How do you control the temperature of a package?
The temperature-controlled courier service may include using insulated materials like foam or aluminium foil, gel packs, dry ice, or an active container to better control the temperature of your package. There are also vacuum insulation panels, which are slightly expensive but are best for minimizing heat transfer.
What is a temperature-controlled LTL?
Refrigerated less-than-truckload transportation can be described as the shipping of perishable items in temperature-controlled trucks. This doesn’t require one customer to have a full truckload of freight.
