Except according to 349.21, lithium metal (nonrechargeable) cells and batteries and lithium-ion (rechargeable) cells and batteries are mailable in limited quantities domestically via air or surface transportation when they are installed in or packed with the equipment they are intended to operate. Unless otherwise excepted, lithium metal and lithium-ion batteries (without equipment) are mailable in limited quantities domestically via surface transportation only. Lithium metal and lithium-ion batteries installed in or packed with used, damaged, or defective electronic devices (excluding devices that are new in original packaging, and manufacturer-certified new or refurbished devices) meeting all mailability requirements in 349 are mailable via surface transportation only.

Note: DOT-approved lithium battery markings must be applied to all mailpieces when there are more than two mailpieces in a single consignment as defined in 349.12b.

Shipping lithium batteries by mail: 3 things you must know

If you&#;re in the hazmat business, you&#;re no stranger to Publication 52 from the United States Postal Service. Affectionately referred to as &#;Pub 52,&#; this public document (a.k.a. &#;Hazardous, Restricted, and Perishable Mail&#;) outlines the do&#;s and don&#;ts for the safe transport of Dangerous Goods via the U.S. mail.

One of the thorniest topics in Pub 52 is lithium batteries. As more new e-commerce companies depend on cheap, efficient, rechargeable battery power, transport of lithium batteries by mail will only grow.

Not surprisingly, shipping lithium batteries by mail is even more complicated than shipping them by other means. We recently posted a complete guide to shipping lithium batteries via the USPS  based on the most recent update of Pub 52 from June .

If you don&#;t have time to digest that whole page, here are your three key takeaways.

#1: Yes, you can ship lithium batteries via USPS. However &#;

There are currently six types of lithium batteries eligible for shipment, in varying domestic or international quantities, via USPS:

  • Lithium-ion (rechargeable) battery, UN
  • Lithium metal battery, UN
  • Lithium-ion (rechargeable) battery contained in equipment, UN
  • Lithium-ion (rechargeable) battery packed with equipment, UN
  • Lithium metal (or lithium alloy) battery contained in equipment, UN
  • Lithium metal (or lithium alloy) battery packed with equipment, UN

Don&#;t forget the new lithium battery marks that became mandatory this year!

However&#;you knew that was coming, right?&#;you cannot ship fully regulated or the damaged or recalled versions of these batteries via U.S. mail. Here&#;s another way to think of it: If the batteries you want to mail require a Class 9 hazard label, per 49 CFR 173.185(c) requirements, they&#;re a no-go with USPS.     

#2: Do your homework on packaging

As every hazmat pro knows, eligible and compliant are two entirely separate things. Your batteries might be eligible for shipping via U.S. mail, but you need the right battery packaging to make those shipments compliant.

You must follow USPS Packaging Instructions 9D strictly to prevent batteries from short-circuiting,  overheating or catching fire. Your outer packaging doesn&#;t have to be UN Specification, but it does need to be a strong, sealed and cushioned package to prevent movement.

International packaging requirements require solid, rigid packaging (to prevent crushing or exposure) that&#;s adequately sized to see the lithium battery mark (plus applicable number) without folding. International shipments in padded and poly bags are only allowed with button cell batteries under a very specific set of circumstances.

#3: Harmony only exists in boy band songs

Getting USPS lithium battery shipping requirements to live in complete harmony with all other intermodal carriers and jurisdictions is umm, well &#; as easy as trying to sing all the parts of a Jonas Brothers song at the same time. (Ask your kids.)

When it comes to harmonization, PHMSA and international organizations such as ICAO and IMO have made great strides to synchronize their regulations, but the U.S. Postal Service isn&#;t quite there yet. Ensuring you&#;ve met all the end-to-end mail and shipping restrictions requires extra diligence.

Here&#;s the bottom line: Even with the current, complex restrictions, the reduced shipping costs and recordkeeping provisions of mailing lithium batteries can make the USPS a smart and viable option. Now quit humming &#;A Little Bit Longer&#; and get back to work!
