  You’ve just purchased a shipping container and plan to store items that are sensitive to moisture. Given enough time in stagnant storage spaces, there are a wide range of materials susceptible to water-related damage. What items can be harmed by humidity in shipping containers? There a few, including: Clothing Fabric furniture Wood materials Cardboard and paper materials Organic materials such as plants or food So what are the risks? What is causing the problem? What are the solutions to keeping the humidity levels under control?  Let’s break it all down! Shop Rent-A-Container! Why is There Humidity in Shipping Containers Despite all their value and durability, shipping containers are vulnerable to humidity and condensation. Their metal surfaces make them especially temperature-conductive. Weather, light level, and ambient heat sources all affect the amount of moisture in the air in the container. If a shipping container’s internal air becomes too warm compared to the coolness of the side walls, it causes condensation to collect on the outer surfaces and ceiling.  What is “Container Rain?” This term is used to describe the collected condensation. You may see water actually dripping from the ceiling or walls of a container. Shipping condensation can damage your cargo through a variety of means including: Warping various materials like plastic, metal, and wood Corroding metals Producing mold and mildew, especially if you have organic products or materials in your container Causing the deterioration of packaging, especially cardboard Why Does Humidity in Shipping Containers Cause Problems? What’s the science behind shipping container condensation? Condensation occurs when air reaches a “dew point”. Sometimes, shipping container walls can become too cool while the air inside the container can stay or become warm. This causes the water content in the air to condense as it transitions into a liquid from a vapor. The liquid then builds up and collects on the interior metal surfaces of a shipping container. Over time, this moisture can drip onto sensitive cargo. As you might imagine, condensation dripping onto equipment or products that are particularly sensitive to moisture can result in hundreds of thousands of dollars lost and serious setbacks.  Shipping Container Condensation Issues: Consider natural temperature fluctuations during any given day. At Nighttime, shipping containers are usually cooler than during the daytime.  Ambient temperature from the humidity outside a container can also change overall shipping container temperature. Available air space plays a factor. Shipping containers that have a lot of extra air space also have a lot of extra moisture content from that open air. Condensation is, therefore, more likely. The moisture content in any shipped goods can play a role. For instance, paper, wood, cardboard, or any other organic materials contain trace amounts of moisture, which can eventually dew as the internal temperature of the container rises. Other commonly shipped products, like certain chilled foods and beverages, can produce their own condensation, adding to the problem. Ventilation is incredibly important. Shipping containers that do not have proper ventilation installed or which have their vents obstructed by debris will cause extra moisture to build up. Air flow can equalize temperature, but a lack of airflow causes heat to collect inside a shipping container. Opening the doors on a hot day will allow more heat inside the container. Loading and unloading the container can also affect its overall ambient temperature. For these reasons, it’s a good idea to invest in certain controls to reduce condensation in your shipping containers. You can’t completely eliminate moisture buildup, but you can control condensation through a variety of techniques. 6 Tips for Shipping Container Moisture Control How do you stop condensation in a shipping container?  Good question. There are a few ways to mitigate the risk of moisture damage in a shipping container. Keep in mind that no single method below is the best way to seal your shipping container and stop condensation from affecting your goods. But implementing several of these will result in better control and removal of shipping container condensation. 1. Improve Ventilation First and foremost, investigate the ventilation situation for all your affected shipping containers right away. Most shipping containers feature vents – these usually include 10 holes punched into steel walls. They also usually have an external bracket over the top, which helps enable airflow without compromising the watertight nature of the shipping container. If, for some reason, your shipping container doesn’t already have these vents, you need to get some installed right away. Ventilation is super important since it funnels warm and moist air out of the container and draws in cool and dry air. This equalizes the temperature on the container’s interior and lowers the likelihood of condensation. Granted, ventilation isn’t the ideal solution for everyone. If you ship goods to wet environments, vents can actually make the problem worse. Furthermore, you might already have enough vents, but they might just be blocked because of your shipping containers being packed too tightly or because of debris clogging the holes. Either way, look at your ventilation situation and change things according to your needs. 2. Use Insulation In a nutshell, insulators keep your cargo contents warmer than the normal dew point that leads to container rain. In essence, this prevents the ambient moisture in the air from condensing into a liquid form in the first place. Remember, temperature differences between the container walls and ambient air are what cause condensation in the first place. 3. Use Dehumidifying Tools A dehumidifier (or several) is another great air condensation solution. Dehumidifiers do exactly what the name suggests; they remove humidity from the air by sucking it away and storing it in a receptacle. The resulting air is drier than normal, so even if there is a temperature variance between your container’s internal air and the walls, no moisture is left to condense. Remember, dehumidifiers do require maintenance. You need to periodically empty the receptacles where they collect the moisture from the air. You can alternatively set up a hose system and plumb the moisture out of

If you’ve ever had to travel on a highway, you’ve probably noticed the labels on shipping containers without even realizing it. Now, you’re the person responsible for making sure shipping container labeling requirements are met. How can you maintain compliance? Or, maybe you want to impress your family with trivia on the next road trip. How do you do it? Simple. Do your research. Keep reading for basic information on shipping container labels to get you started. Why do shipping containers have labels?  Shipping containers have labels because governments require them. The labels convey all sorts of information to those who know how and where to look. They do everything from identify the specific container from the millions of others in the world, indicate the size and even notify us of what is contained inside them. Shipping container labeling requirements: Where to find a label  Important markings can be found on all parts of a shipping container. Here is where you can find shipping container labels: Door end: The door end is the part of the container that holds the most information. On the door end, you will find the maximum gross weight, tare weight, maximum payload, height warning. You may also find the owner’s logo and repair recommendations. Side: The side has the identification number which contains the BIC code, serial number, and check digit. Top: The top includes the identification number and size and type codes. Front end: The front end includes the identification number and size and type codes. Components of shipping container labels Below are definitions of the common markings that people find on shipping containers. This will help you identify the labels when you see them: Maximum gross weight The maximum gross weight is a number found on the door end of the shipping container. It tells the people packing the container the maximum weight the container can carry in pounds and kilograms, including its own weight, which is called tare weight.  Maximum payload The maximum payload is the maximum amount of weight that can be packed into the container as cargo. Misdeclaring this number can cost lives and property damage. This number matches the number on the packing slip and doesn’t include tare. It’s represented on the back of the container to let the customer know what to expect from the payload inside. Height warning Height markings are mandatory on shipping containers more than 8 feet, 6 inches tall. These are usually pictured as measurement figures on a yellow background outlined in black. This number is displayed on the right-hand corner of each side. Identification Number The identification number comprises three important parts: the BIC code, serial number, and check digit.  BIC code The Bureau International des Containers et du Transport Intermodal (BIC) issues an owner code to shippers. Each code is unique to identify the owner of the specific container. There can be no duplicate BIC codes. The owner code, or BIC code, is the first 3 letters of the identification number. A fourth letter describes the equipment category. Serial number The serial number is 6 numbers serializing the shipping container. This allows for tracking of the container. Check digit The check digit is a digit within the serial number that is used to check the validity of a serialized shipping container’s identification number.  Size and type codes ISO Codes tell the shipper the size and type of container no matter what region of the world they are in by using a standardized codification system that is globally accepted. Other markings on a shipping container Here are some other markings on a shipping container: Owner name and logo: This identifies the company that owns the shipping container. Hazard warnings: Plates that identify any hazardous materials contained in the shipment are present. Caution stickers: This includes “Warning High Cube” and other cautions. CSC plate: The Container Safety Convention (CSC) plate is required for international trading. It highlights the most important owner and safety information in one place. What about hazardous materials? Companies must clearly mark hazards and convey important information using labels on shipping containers to remain in compliance with existing guidelines. The Occupational Safety and Health Administration, or OSHA, states that shipping containers transporting certain hazardous materials: “[A]n HCS 2012 label compliant with paragraph 1910.1200(f)(1) must be on the outside of the shipping container or attached to any accompanying shipping papers or bill of lading. This accommodation will provide basic information to downstream workers, such as warehouse or dock workers who may be exposed in case of a spill or release or other emergency. The shipping container should also be labeled in accordance with DOT and/or International Maritime Organization (IMO) labeling regulations or requirements during shipping.” With these tips, you can identify shipping container labels and markings like a pro.

What is a High Cube (HC) Shipping Container? While these containers are available in sizes and layouts similar to any other standard sized container, high cube shipping containers are defined by their height. A high cube shipping container or HC container is an intermodal storage container unit with an external height of 9ft. 6in. That’s a 2,895.6 mm shipping container for the rest of the world. It’s added height gives owners and renters additional headspace and a convenient way to increase storage capacity by adding additional volume, without needing a longer container.

Standard Shipping Containers vs. High Cube Shipping Containers As mentioned above, the main difference between a standard shipping container and a high cube shipping container is the height. High cubes stand an additional foot above the 8ft. 6in. standard shipping container. This height difference also results in taller doors and some additional container weight. What are the Dimensions of a High Cube Container? *(note that the exact internal and door dimensions can vary slightly by manufacturer and factory) External Dimensions for Common High Cube Containers: Height: 9’ 6” Width: 8’ Length: 20’, 40’ or 45’ Door Opening Width: 7’ 8” Height: 8’ 6” Internal Dimensions of a High Cube Container Height: 8’ 10” – Height varies slightly depending on floor type and material width Width: 7’ 9” Length: 20 ft – 19’ 4”; 40 ft. – 39’ 6” 20 ft.

Now that you know the specs of the two most common shipping container heights, how do we choose between the two of them? Let’s answer a few important questions to help us decide on which shipping container will serve your needs. Is weight a factor? If your main concern for transporting or storing heavy items is weight, then the recommendation is to choose the shortest height and shortest length that will still allow you to fit all your belongings. What are you using the container for? Storage or shipping containers are used for many reasons these days. Here are a couple of examples that might help you when choosing the type of container needed based on the unit’s intended use.  Storing Property For those who plan to keep their shipping containers in their backyards to secure their belongings, or for temporary storage of goods, tools and vehicles will most likely fit in an 8ft 6in standard container.  If you are looking to store taller items, or if you need added storage volume but your yard is unable to accommodate the extended length of a container, a high cube container may be just what you need. Offices, Workspaces, or Shipping Container Homes If you plan to work in the container space often, or want to convert your container into a living space, we recommend 9’ 6” high cube containers. This will give you and anyone else utilizing that space additional comfort and headspace. You’ll thank us later. Price Difference: High Cube Shipping Containers vs Standard Shipping Containers Your budget is an important factor in choosing the right storage or shipping container for you or your business. If all other variables are equal, standard sized shipping containers and high cube containers are relatively equal in price. Prices for high cube containers will be a little higher to account for their weight and added volume but the difference is often fairly small. *This is only true if you have done your homework to ensure that you are comparing containers with the same width, length, condition type, and delivered from the same location (or equal miles shipped).
