Attachment 1, passage 2The contents of this guide do not have the force and effect of law and are not meant to bind the public in any way. This guide is intended only to provide information to the public regarding existing requirements under the Hazardous Materials Regulations. INTRODUCTION This compliance resource was prepared to assist a shipper to safely package lithium cells and batteries for transport by all modes of transportation according to the latest regulatory requirements. This guide provides scenario-based situations that outline the applicable requirements that a shipper must follow to ship packages of lithium cells and batteries in various configurations. Each distinct shipping guide in this document refers to the regulatory requirements for a specific lithium cell/ battery type, configuration, and size. In this way, a shipper will easily find the applicable provisions that they must follow depending on the scenario they encounter as a shipper. Please note that these shipping guides are based on the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) and can be used as a compliance tool to help outline applicable scenario-based regulatory requirements; this document is not a substitute for the HMR. While every effort has been made to provide a simplified compliance resource consistent with the HMR, if there is any instance in which this document is inconsistent with the HMR, then the HMR requirements supersede this guide. The regulations themselves are the final authority for proper shipping procedures. The HMR includes provisions for the classification, packaging, hazard communication (e.g., package marking, labeling, shipping papers), stowage, and handling of all hazardous materials. The purpose of these regulations is to protect the safety of people, property, and the environment when hazardous materials such as lithium batteries and battery-powered devices are shipped. If the applicable minimum regulatory requirements are not followed, lithium cell or battery shipments may be more likely to contribute to fires, injuries, or other incidents during transport. Whether shipping a single battery, a palletized load of batteries, or a battery-powered device, the safety of the package, and those who handle it along its journey, depends on compliance with the HMR. Failure to comply with the applicable regulations may result in fines or even criminal prosecution. For any questions about regulatory requirements, please contact our Hazardous Materials Information Center at 1-800- 467-4922/202-366-4488 or infocntr@dot.gov. The Information Center can answer any regulatory questions and provide additional compliance resources. Effective May 10, 2024, the latest rulemaking (HM-215Q, published April 11, 2024) extends the requirement that lithium ion batteries must be marked with the Watt-hour rating on the outside case to include batteries larger than 100 Wh, revises the test summary requirement, specifies quantity limits for cells and batteries packed with equipment, and removes exceptions for small lithium cells and batteries shipped by air (when not packed with or contained in equipment). In addition, HM-215Q removes the telephone number requirement from the lithium battery mark, with a phaseout date of December 31, 2026. As such, this guide now includes footnotes specifying the phaseout date in each instance of the lithium battery mark. 2#

Attachment 1, passage 3CELL VS. BATTERY WHY LITHIUM BATTERIES ARE REGULATED IN TRANSPORTATION Lithium cells and batteries power countless items that support everyday life, from portable computers, cordless tools, smartphones and watches, to wheelchairs and motor vehicles. Our society has come to depend on lithium cells and batteries for an increasingly mobile lifestyle. Today's lithium cells and batteries are more energy dense than ever, bringing a steadily growing number of high-powered devices to market. With the increased energy density comes greater risk and the need to manage it. Shippers play an important role in reducing this risk and preventing incidents—including fires aboard aircraft or other transport vehicles. CELL: A cell is a single encased electrochemical unit. BATTERY: A battery is made up of multiple electrically connected component cells, such as in a laptop computer battery. Note: A battery can also be comprised of only a single cell, such as the common AA, C, or a coin cell. A single cell battery is considered a “cell” and must be offered for transportation in accordance with the requirements for cells. The risks posed by lithium cells and batteries are generally a function of type, size, and chemistry. Lithium cells and batteries can present both chemical (e.g., corrosive or flammable electrolytes) and electrical hazards. Unlike standard alkaline batteries, most lithium batteries manufactured today contain a flammable electrolyte and have an incredibly high energy density. They can overheat and ignite under certain conditions, such as a short circuit, overcharging, or mechanical damage. Once ignited, lithium cell and battery fires can be difficult to extinguish. Additional, although infrequent, events can result in lithium cells and batteries experiencing thermal runaway, a chain reaction leading to a violent release of stored energy and flammable gas. This thermal runaway can propagate to other batteries or combustible materials nearby, potentially resulting in large fires with severe consequences. The Federal Aviation Administration (FAA) Technical Center issued a series of test reports in 2004, 2006, 2010, and 2014 that characterized the hazards posed by lithium cells and batteries transported as cargo on aircraft and the effectiveness of certain aircraft fire suppression agents and packaging configurations in mitigating the associated risks. The FAA Technical Center testing shows that oxygen starvation through depressurization in the case of cargo aircraft, common shipping containers (e.g., unit load devices), or aircraft fire suppression systems are not effective in containing or suppressing many potential lithium cell or battery fires. Lithium cells and batteries can become dangerous and cause fires and electrical shocks if not safely packaged and handled when transported. Misused, mishandled, modified, improperly packaged, improperly stored, overcharged, damaged, or defective lithium cells or batteries can short circuit, overheat, and sometimes cause fire. The heat from a single cell in thermal runaway can propagate from cell to cell and package to package until the entire shipment has been consumed. Temperatures of lithium cells or batteries in thermal runaway are sufficient to ignite typical fiberboard packaging and nearby materials. Always remember that ALL lithium cells and batteries are hazardous materials when being transported, no matter the size or quantity. However, there may be exceptions from the regulations depending on whether the cells and batteries meet specific: • Size limitations • Packaging requirements • • Hazard communication requirements Additional requirements for air transportation.

Attachment 1, passage 4THE HMR, INTERNATIONAL, AND MODAL REQUIREMENTS This document provides generalized guidance on the requirements for proper packaging and hazard communication of shipments of lithium cells and batteries and lithium battery-powered equipment by all modes of transportation. Shipments to, from, or within the United States are subject to the HMR. For international transport, PHMSA authorizes the use of the International Civil Aviation Organization's Technical Instructions for the Safe Transport of Dangerous Goods by Air (ICAO TI) and the International Maritime Dangerous Goods Code (IMDG Code) subject to the additional conditions and limitations of the HMR specified in subpart C of part 171 of the HMR (§§ 171.22-26). VESSEL TRANSPORTATION Lithium batteries and battery-powered equipment may be transported within the United States by vessel and by motor vehicle or rail either before or after being transported by vessel in accordance with the IMDG Code. We recommend that shippers consult the most recent edition of the IMDG Code, issued by the International Maritime Organization (IMO) for additional requirements. Publications and regulations issued by IMO can be found at: www.imo.org. AIR TRANSPORTATION Lithium batteries and battery-powered equipment may be transported within the United States by aircraft and by motor vehicle or rail either before or after being transported by aircraft in accordance with the ICAO TI. We recommend that shippers consult the most recent edition of the ICAO TI for additional requirements, along with any applicable origin/ destination State Variations. State Variations are additional conditions and limitations imposed by the country of origin and destination. For example, US State Variations contain the additional HMR requirements that apply when shipping to, from, or within the US by air under the ICAO TI. Publications and regulations issued by ICAO can be found at: www.icao.int. For both international and domestic shipments, we also recommend checking with the air carrier for any additional requirements. Many air carriers have supplemental policies and/or limitations with respect to lithium battery shipments. These requirements can often be found by consulting directly with the air carrier or International Air Transport Association (IATA) publications. Air carriers, working closely with the FAA, use their Safety Management Systems (SMS) to evaluate their ability to safely carry lithium batteries and determine safety mitigation strategies. General FAA hazmat resources can be found at www.faa.gov/hazmat, with specific lithium battery resources at https://www.faa.gov/hazmat/resources/lithium_batteries. In summary, when shipping batteries for air transportation, shippers should always consult their air carrier or ICAO/IATA publications for both country-specific and carrier-specific policies/limitations. 4#

Attachment 1, passage 5LITHIUM BATTERY TYPES There are many different chemistries of lithium cells and batteries, but for transportation purposes, all lithium cells and batteries fall into one of two basic types: lithium ion and lithium metal. Both battery types are characterized by a higher energy density and a longer operating life than alkaline, nickel cadmium, and nickel metal hydride chemistries. • Lithium ion, including lithium polymer: • • are generally rechargeable (secondary) batteries are found in a wide range of electronic devices such as laptop and tablet computers, cellular telephones, hybrid vehicles, etc. • Lithium metal: • • • are generally non-rechargeable (primary, one-time use) have a longer life than standard alkaline batteries are commonly used in hearing aids, wristwatches, smoke detectors, cameras, key fobs, children’s toys, etc. LITHIUM CELLS AND BATTERY TESTING REQUIREMENTS Shippers are responsible for ensuring that lithium cells and batteries offered for transportation have passed the design tests found in the United Nations (UN) Manual of Tests and Criteria, Section 38.3. The UN 38.3 testing accounts for transportation impacts such as: • • Altitude External short circuit • • Forced discharge Impact/crush • • Overcharge Shock • • Thermal test Vibration Effective January 1, 2022, lithium cell and battery manufacturers and subsequent distributors of lithium cells or batteries, except for button cells installed in equipment (including circuit boards), manufactured on or after January 1, 2008 must make a lithium battery test summary available to others in the supply chain. The test summary includes a standardized set of elements that provide traceability and accountability to ensure that lithium cell and battery designs offered for transport meet UN 38.3 test requirements. We recommend the shipper check with the battery manufacturer or distributor to determine if a battery design has passed these tests, or obtain, if possible, the test summary. For additional information on test summaries, refer to PHMSA’s "Lithium Battery Test Summaries (TS)” outreach publication. Any change or modification to a lithium battery that would lead to a failure of any of the UN 38.3 tests must be considered a new type and subjected to the required tests. See the UN Manual for the types of changes that may be considered sufficiently different from a tested type and that may lead to a failure of a lithium battery test result. See § 173.185(a) for all testing and test summary requirements. Refer to §§ 173.185(d)(1) and (e), respectively, for exceptions from the testing requirements for lithium cells or batteries shipped for disposal or recycling and for low production runs and prototype lithium cells or batteries.

Attachment 1, passage 6HOW ARE LITHIUM BATTERIES REGULATED? Lithium cells and batteries are Class 9 (miscellaneous) hazardous materials. There are eight possible descriptions for lithium cells and batteries, depending on the battery chemistry. These descriptions, or proper shipping names, are found in the Hazardous Materials Table (HMT) in § 172.101 of the HMR. They are as follows: • • • • • Stand-alone—Package contains only the cells/batteries—no equipment: • UN3090, Lithium metal batteries including lithium alloy batteries • UN3480, Lithium ion batteries including lithium ion polymer batteries Packed with—Package contains not only the equipment, but also cells/ batteries that are not installed in the equipment: • UN3091, Lithium metal batteries packed with equipment including lithium alloy batteries • UN3481, Lithium ion batteries packed with equipment including lithium ion polymer batteries Contained in—Package contains equipment with cells/batteries installed: • UN3091, Lithium metal batteries contained in equipment including lithium alloy batteries • UN3481, Lithium ion batteries contained in equipment including lithium ion polymer batteries Vehicles—Package or shipment contains a vehicle powered by lithium batteries: • UN3171, Battery-powered vehicle Cargo Transport Unit—Lithium batteries installed in a cargo transport unit and designed only to provide power external to the cargo transport unit. • UN3536, Lithium batteries installed in cargo transport unit lithium ion batteries or lithium metal batteries BATTERY SIZE – SMALLER BATTERY THRESHOLDS What are considered “Vehicles” or “Equipment” in the HMR? Vehicles are self-propelled apparatuses designed to carry one or more persons or goods. Examples of such vehicles are electrically-powered cars, motorcycles, scooters, three- and four-wheeled vehicles or motorcycles, trucks, locomotives, bicycles (pedal cycles with an electric motor) and other vehicles of this type (e.g. self-balancing vehicles or vehicles not equipped with at least one seating position), lawn tractors, self- propelled farming and construction equipment, boats, aircraft, wheelchairs and other mobility aids. Equipment means the device or apparatus for which the lithium cells or batteries will provide electrical power for its operation. It is important to remember that the size of the cell or battery has important implications for shipping requirements. Size refers not only to physical dimensions and weight, but also the energy capacity of the battery. For lithium ion cells and batteries, size is measured by Watt-hour (Wh) ratings. For lithium metal cells and batteries, size is measured by lithium content in grams (g). The Wh rating is often marked on the outside case of the lithium ion cell or battery. Beginning May 10, 2024, the Wh rating must be marked on the outside case of all lithium ion batteries regardless of size (see § 173.185(a)(5)). The size of a lithium cell or battery is an important aspect of classification because “smaller” cells and batteries qualify for certain exceptions from regulatory requirements when packed in certain quantities. For the purposes of DOT regulations, a “smaller” cell or battery is as follows: • Lithium Ion: Cells equal to or less than 20Wh; and batteries equal to or less than 100Wh • • For highway and rail ONLY: Cells not exceeding 60Wh; and batteries not exceeding 300Wh Lithium Metal: Cells equal to or less than 1g; and batteries equal to or less than 2g • For highway and rail ONLY: Cells not exceeding 5g; and batteries not exceeding 25g Note: For a single cell battery, such as a typical coin cell or standard AA or AAA replacement battery, refer to the size for cells. Cells and batteries that exceed these “smaller” cell or battery size thresholds must be shipped as fully regulated Class 9 hazardous material. The shipping requirements for these fully regulated cells and batteries are more stringent. The shipping guides outlined on page 7 and the flowcharts on pages 8 and 9 make the distinction between size thresholds, when applicable, for shipping purposes. 6#

Attachment 1, passage 7DISPOSAL OR RECYCLING LITHIUM BATTERY PROVISIONS FOR MOTOR VEHICLE ONLY Lithium cells and batteries, including those contained in or packed with equipment, being shipped for disposal or recycling may qualify for certain exceptions in § 173.185(d) of the HMR. The following exceptions only apply when transported by motor vehicle to a permitted storage facility, disposal site, or for the purposes of recycling: • UN 38.3 cell and battery testing • UN specification packaging requirements (when packed in a strong outer packaging) In addition, when these shipments meet the applicable size, packaging, and hazard communication conditions for “smaller” cells and batteries in § 173.185(c) of the HMR, they are also eligible for the “smaller” cells and batteries exceptions. Please note that all other requirements of the HMR apply, including, but not limited to, protecting the lithium cells and batteries from short circuiting and from damage caused by shifting within the outer package. For more details on the requirements for a specific shipment, use the appropriate shipping guide in this document. Many packages designed to ship lithium batteries for recycling are subject to the terms of a DOT Special Permit (DOT-SP). When utilizing packaging subject to the terms of a DOT-SP, the exact instructions of the DOT- SP provided by the manufacturer must be followed. SHIPPING DAMAGED, DEFECTIVE, OR RECALLED (DDR) LITHIUM BATTERIES Lithium cells or batteries that have been damaged or identified by the manufacturer as being defective for safety reasons, that have the potential of producing a dangerous evolution of heat, fire, or short circuit (e.g., those being returned to the manufacturer for safety reasons) may only be transported by highway, rail, or vessel. These cells or batteries are strictly forbidden for transportation by aircraft. Furthermore, they must be packaged according to the provisions of § 173.185(f), which include: • Placing the cell or battery in individual, non-metallic inner packaging that completely encloses the cell or battery • Surrounding the inner packaging with cushioning material that is non-combustible, electrically non-conductive, and absorbent • Packaging the inner packaging in Packing Group I performance level packaging. Note that only one inner packaging may be placed in an outer packaging (i.e., only one cell or battery per package) • Marking the outer packaging with an indication that the package contains a damaged/defective battery, in addition to any other required marks and labels on the package. Note that there are no exceptions from any HMR requirements (e.g., training, shipping papers, marking, labeling) for DDR lithium cells or batteries. Many packages designed to ship damaged, defective, or recalled batteries are subject to the terms of a DOT Special Permit (DOT-SP). When utilizing packaging subject to the terms of a DOT-SP, the exact instructions of the DOT-SP provided by the manufacturer must be followed.
