What is a UN3090 Label?
Lithium metal batteries are classified as dangerous goods due to their flammability and chemical reactivity if damaged or improperly handled. The UN3090 label is required for shipments of standalone lithium metal batteries to communicate hazards and support safe transport. This resource explains UN3090 label requirements, key regulatory considerations, and best practices for compliant shipping.
The UN3090 label applies to lithium metal batteries shipped on their own, without being installed in or packed with equipment. Because lithium metal batteries contain metallic lithium, they present different risks and regulatory requirements compared to lithium-ion batteries.
The UN3090 label identifies packages containing standalone lithium metal cells or batteries. It alerts carriers and emergency responders to the presence of batteries that may present fire and chemical hazards if exposed to damage, heat, or moisture.
UN3090 labels are used for lithium metal batteries shipped independently, while UN3091 labels apply to lithium metal batteries that are contained in or packed with equipment. Standalone lithium metal batteries typically have stricter transport controls due to increased handling risks.
Lithium metal battery shipments require specific labeling depending on how the batteries are packaged. UN3090 is one of the primary classifications used for standalone lithium metal batteries and plays an important role in ensuring regulatory compliance and safe handling.
UN3090 labeling requirements ensure shipments are clearly identified and handled according to dangerous goods regulations. This includes required markings, label sizing, placement, and durability considerations.
UN3090 labels must display the UN number, UN3090, along with the appropriate lithium battery hazard symbols. Additional markings or handling statements may be required depending on transport method and shipment classification.
UN3090 labels are generally 100mm × 100mm, though specific size requirements may vary by carrier or transportation mode. Labels must be clearly legible and easily visible on the exterior of packages.
The UN3090 label must be placed on the outside of the package in a visible location and must not be covered or obscured by packaging materials. When multiple hazard or shipping labels are required, they should be grouped together for clarity.
Because lithium metal batteries contain metallic lithium, shipments often require additional regulatory controls. Understanding these requirements helps prevent shipment rejection or compliance violations.
Certain small lithium metal batteries may qualify for limited exceptions based on lithium content, packaging, and transport mode. Exceptions vary by carrier and regulatory authority and should be verified before shipping.
Large shipments of lithium metal batteries may require a Class 9 hazard placard on transport vehicles or freight containers. Placard requirements depend on shipment size and applicable DOT or ICAO regulations.
UN3090 shipments may require documentation such as a Shipper’s Declaration for Dangerous Goods, particularly for air transport. Documentation must accurately identify battery classification and confirm compliance with applicable regulations.
Ensure your shipments meet all regulatory requirements with GMP Labeling’s solutions. GMP provides both stock and custom UN3090 labels that comply with IATA, DOT, and IMDG standards. The labels are made from durable materials that withstand handling and transport. Custom printing options including logos, serial numbers, and barcodes make it easy to tailor labels to your needs. Expert guidance ensures your labeling and documentation are fully compliant. With GMP, you can simplify compliance, reduce shipping risk, and ship lithium batteries with confidence.
