USPS Final Lithium Battery Rule

Lithium battery rules final with USPSThe USPS has issued a Final Rule related to the transport of lithium batteries that will revise Publication 52 (Hazardous, Restricted, and Perishable Mail).


The revision aligns much of Publication 52 with the changes adopted by the PHMSA in August 2014 in the final lithium battery rule, HM-224F.


Some highlights of the Rule include:

  • Use of terminology describing lithium content with watt-hours for lithium-ion cells and batteries;
  • Adoption of separate shipping descriptions for lithium metal batteries and lithium-ion batteries;
  • New requirements for the transport of small lithium cells and batteries contained in equipment; and
  • New marking requirements and options for lithium batteries installed in equipment packaged with equipment and shipped without equipment.


The Federal Register notice will not include the full revised language of Publication 52.  Instead, this language will appear in a February 5, 2015 Postal Bulletin.
