There are many rules and regulations in place when it comes to applying battery labels to packages containing lithium batteries for transport. .
So why do you have to jump through hoops when shipping lithium batteries? Like we mentioned above, they pose very real safety issues. It’s why lithium batteries are classified as dangerous goods. If transported. .
First things first: you need to know which kind of lithium battery you are shipping. There are 2 classification types of lithium batteries: lithium metal and lithium ion. And depending on. .
Packing Instructions (PI) are just another piece of the battery label puzzle. They were created and implemented by the International Air Transport Association (IATA). Specifically,. .
Now that you know the different lithium batteries types, you’ll have a better idea of which labels your package will need. So how do you illustrate the battery material being shipped? There’s a system in place for this exact. To meet global shipping standards, a lithium battery shipping label must include key regulatory markings, such as the Class 9 hazard label, UN number, handling warnings, orientation arrows, and other relevant information.
