According to the International Maritime Dangerous Goods Code (IMDG Code), BESS is classified as Class 9 hazardous goods, with the United Nations number UN3536.
Because batteries are classified as dangerous goods due to fire and explosion risk. That means stricter packaging, labelling, documentation, and carrier approvals. This guide explains everything you need to know to stay compliant and avoid costly delays – from battery classifications to mode-specific rules and best practices for shipping safely.
Except for containerized lithium-ion battery energy storage systems and vehicles powered by lithium batteries (pure electric or hybrid), packages containing lithium batteries or battery packs must be affixed with the 9A dangerous goods label as shown in Figure 4 or the lithium battery mark as shown in Figure 5, as required.
12. March 2025 In recent years, demand for the maritime transportation of containerised Battery Energy Storage Systems (BESS) has grown significantly. However, due to the high safety risks associated with energy storage containers, their transportation poses new challenges to maritime safety.
Except for vehicles driven by lithium batteries (pure electric or hybrid), containers containing lithium battery hazardous goods must have Class 9 hazardous goods labels and UN number markings affixed to each side and each end of the container (for lithium-ion battery energy storage systems, on two opposite sides).
Segregation: It is recommended to segregate lithium battery containers from those containing other dangerous goods, particularly flammables, by at least one container bay (6 meters). Securing: All cargo must be secured within its container and on the vessel in accordance with the CTU Code and the vessel's Cargo Securing Manual.
Most lithium batteries are classified as Class 9 dangerous goods but the exact handling requirements depend on: Other battery types – like lead-acid, nickel-metal hydride (NiMH), and dry cell batteries — may fall under different categories, but all require proper classification, documentation, and packaging to move legally and safely.

According to NFPA 855, individual energy storage system units should generally be separated by at least three feet, unless the manufacturer has conducted large-scale fire testing (part of UL 9540A) to prove a smaller distance is safe. This prevents a fault in one unit from spreading. Adhering to established codes for battery cabinets protects your investment, ensures safety, and maximizes performance by preventing thermal issues before they start. Understanding the reasons behind these rules helps reinforce their importance. Accessibility and Maintenance Needs. Specifically, safety regulations mandate a particular spacing to. Ever wondered why your neighborhood battery farm isn't right next to the playground? The concept of energy storage building distance is more than real estate logistics—it's a cocktail of safety protocols, fire risks, and even zombie-apocalypse-level contingency planning (okay, maybe not zombies. storage system must also comply with 110.
[PDF Version]Therefore, if you install multiple storage units, you have to space them three feet apart unless the manufacturer has already done large-scale fire testing and can prove closer spacing will not cause fire to propagate between adjacent units.
In Section 15.5 of NFPA 855, we learn that individual ESS units shall be separated from each other by a minimum of three feet, unless smaller separation distances are documented to be adequate and approved by the authority having jurisdiction (AHJ) based on large-scale fire testing.
Individual ESS units shall have a maximum stored energy of 20 kWh per NFPA Section 15.7. NFPA 855 clearly tells us each unit can be up to 20 kWh, but how much overall storage can you put in your installation? That depends on where you put it and is defined in Section 15.7.1 of NFPA 855.
You can have up to 40 kWh within a storage or utility space inside the home. For an attached or detached garage or a detached accessory structure, you can go up to 80 kWh. Outdoor installations, including those on exterior walls, can go up to 80 kWh. See the illustration below for a visual example of these capacity restrictions.

[PDF Version]Most groups involved with project development usually agree that energy storage projects are not necessarily different than a typical power industry project finance transaction, especially with regards to risk allocation.
System Pricing: Developing and publishing a standard reference price for different energy storage technologies will help set expectations for what battery prices should be. Currently, many groups only have a narrow view into the pricing of systems, giving rise to confusion over expectations for differently sized systems or different technologies.
Capital Costs The capital cost of an energy storage system is the total value of all of the initial equipment purchased for the project. This is derived from adding the cost of all of the subassemblies and components needed to construct the final version of the product, many times described internally as a Bill of Material (BOM).
This is understandable as energy storage technologies possess a number of inter-related cost, performance, and operating characteristics that and impart feed-back to impacts to the other project aspects. However, this complexity is the heart of the value potential for energy storage systems.
