Per United Nations material classification UN3499, all Maxwell ultracapacitors
have less than 10 Wh capacity to meet the requirements of Special
Provisions 361. When packaged according to the regulation, both individual
ultracapacitors and modules composed of those ultracapacitors shipped
by Maxwell can be transported without being treated as dangerous goods
(hazardous materials).
