DOT and IATA regulations must be followed while shipping lithium batteries. These 5 crucial factors can be used to comply with the DOT HMR criteria and the IATA Dangerous Goods Regulations when shippers and carriers transport lithium metal and lithium ion batteries via highway (road), rail, air (aircraft), and water (vessel).

1. The Dos and Don’ts of Shipping Lithium
Batteries

2. We’ve all heard of lithium batteries… after all, we use them in all our modern tech devices and even in our
cars. But have you ever realized that lithium batteries are categorized as hazardous cargo due to their
higher energy density and flammable electrolytes?
According to the PHMSA, “lithium batteries pose a fire hazard, even when they are no longer useful in
consumer equipment/products. Damaged, defective, or recalled batteries have greater potential than
undamaged lithium batteries to short circuit, release heat, or even cause a fire.” Thus, the PHMSA advises
that appropriate precautions be taken when shipping new lithium batteries or when shipping used,
damaged, or old lithium batteries for disposal or recycling.
Considering the high possibility of the hazards associated with shipping lithium batteries, the U.S.
Department of Transportation (DOT) and the International Air Transport Association (IATA) have both
enacted strict regulations for the transportation of lithium batteries including packaging, marking, and
specific labeling requirements.

3. What is a Lithium Battery?
The term “lithium battery” refers to one or more lithium cells that are electrically connected. A cell is a single encased
electrochemical unit, while a battery consists of multiple electrically connected component cells. A battery can also only be made
up of a single cell, such as the common AA, C, or coin cell.
A lithium battery is like other types of battery. The lithium battery cells contain a positive electrode, a negative electrode, a
separator, and an electrolyte solution. Atoms or molecules with a net electric charge (ions) are transferred from a positive
electrode to a negative electrode through an electrolyte solution. Lithium cells store and release power by converting chemical
potential energy into electrical energy using lithium ions or lithium metal. Electrolyte solutions allow ions to flow freely between
the electrodes.
So, what should manufacturers of lithium batteries and consumer product manufacturers using pre-installed lithium batteries in
products such as watches, smartphones, tablets, laptops, cars, and various other devices and equipment know about the
transportation of lithium batteries?
Understanding the dos and don’ts when shipping lithium batteries is important to adhere to the regulatory requirements while
safeguarding the shipment, people, and environment from fire and explosion hazards. Thus, manufacturers of lithium batteries
and those using lithium batteries as a component of their products must first identify the type and size of the lithium battery being
transported, the categorization of lithium batteries, how the lithium battery will be transported, and the mode of transportation to
be used.
Let’s check these points individually to gain a better understanding of the lithium battery transportation regulations which will
guide on the dos and don’ts when shipping lithium batteries.

4. #1 Understand the type of lithium battery being shipped
Manufacturers of lithium batteries and producers of other goods utilizing lithium batteries as their power
source must first identify the type of lithium battery – “lithium ion battery” or “lithium metal battery”.
What Is the Difference Between Lithium-ion and Lithium Metal Batteries?
Lithium metal batteries contain metallic lithium and are primarily non-rechargeable. They have lithium
metal or lithium compounds as an anode. Included in this group are lithium alloy batteries.
Lithium-ion batteries are rechargeable, and lithium is only present in the electrolyte in the ionic form.
Included in the lithium-ion category are lithium polymer batteries. Lithium batteries are sometimes
abbreviated as Li-ion batteries.

5. These two types of batteries are governed by different shipping regulations and hence, identifying the type
of lithium battery being shipped will enable the appropriate regulations to be followed.

6. #2 Know the size of the lithium battery
The lithium battery size also impacts the dos and don’ts of shipping lithium batteries. The DOT Hazardous
Materials Regulations (HMR) specify the labeling and marking requirements for not only the different
types of lithium batteries but also for the different sizes. Furthermore, the size of the lithium battery can
also impact the decision on the method of transportation – highway, rail, aircraft, or vessel.
Lithium battery size is measured in Watt Hour (Wh) for lithium ion batteries and kilograms (kg) for
lithium metal batteries.
This leads us to point #3, which considers the transportation of lithium batteries in terms of energy
density and the classification as applied by the DOT HMR.
#3 Know the lithium battery classification
The regulations classify lithium batteries based on their size as ‘Fully Regulated’ or ‘Excepted’. Lithium
Batteries of a higher energy density would fall within the fully-regulated category and be subject to stricter
regulations while lower energy density lithium batteries may gain excepted status and have lesser rules to
comply with during transportation. The categorization status of lithium batteries also impacts the mode of
transportation that can be used in the transfer of goods from one destination to another.

7. Fully regulated lithium ion/metal cells or batteries for the purposes of DOT regulations include:
Lithium ion cell or battery Lithium metal cell or battery
• A cell with a Watt-hour rating greater than 20
Wh; and
• A battery with a Watt-hour rating greater than
100 Wh.
• A cell with a lithium content greater than 1g; and
• A battery with a lithium content greater than 2g.
Here’s a good example of the regulatory requirements changing according to the
categorization of lithium batteries for air shipments of stand-alone lithium cells and
batteries.
As of January 1, 2022, according to IATA Packing Instructions 965 (lithium ion batteries) and 968 (lithium
metal batteries), all shipments of stand-alone lithium cells and batteries will be considered fully regulated
and will no longer be subject to Section II provisions for excepted lithium cells and batteries. Stand-alone
lithium cells and batteries can now be shipped under Section IA and IB of PI 965 and 968.

8. #4 How will the lithium battery or batteries be shipped
Another important aspect of shipping lithium batteries is to identify how the lithium battery will be
shipped. For instance, will the lithium battery be shipped separately (stand-alone), with the machine or
equipment (meaning in the same outer packaging as the equipment), or inside the device?
The way that the lithium batteries are going to be packed, labeled, marked, and the mode of transportation
that can be used is dependent on how the lithium ion or metal batteries are going to be shipped.

9. Important Note for air shipments of stand-alone lithium cells and batteries:
As of January 1, 2022, according to IATA Packing Instructions 965 (lithium ion batteries) and 968 (lithium
metal batteries), all shipments of stand-alone lithium cells and batteries will be considered fully regulated
and will no longer be subject to Section II provisions for excepted lithium cells and batteries. Stand-alone
lithium cells and batteries can now be shipped under Section IA and IB of PI 965 and 968.
#5 Mode of Transportation – Highway, Rail, Air, or Vessel
The mode of transportation also plays an important aspect in the dos and don’ts of shipping lithium
batteries due it their capacity to explode and the other unique hazards associated with lithium battery
transportation. Thus, depending on the mode of transporting lithium batteries; either by air, water, or
ground, will impact the regulations that must be followed by manufacturers. It is worth noting that due to
the size and categorization of the lithium battery, some manufacturers may face limited options for the
transportation of lithium batteries.
For example, Lithium-ion cells that exceed 20 Wh but do not exceed 60 Wh are forbidden for transport
aboard aircraft and vessels. Thus, the only mode of transportation available are highway and rail.
