Dear Ms. Shaffer:
This letter is in response to your August 7, 2019, letter requesting clarification of the Hazardous
Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to the shipment of data loggers
containing lithium batteries. In your letter, you explain that a data logger is a piece of equipment
used to track or monitor packages in transport. You are seeking clarification regarding the
provisions for data loggers as discussed in the final report by the United Nations Sub-Committee
of Experts on the Transport of Dangerous Goods (UNSCOE TDG) dated December 21, 2018
(ST/TG/AC.10/C.3/108). You note that while most data loggers are powered by small or
excepted batteries and fuel cells, the number of data loggers in consignments often exceeds the
amounts authorized for hazard communication exceptions specified in § 173 .185( c )(3 ).
Specifically, you ask whether data loggers used to track or monitor packages are subject to the
requirements of the HMR. ·
The answer is yes. Data loggers offered as part of consignments are subject to all applicable
requirements of the HMR. As stated in your letter, the HMR provide exceptions for smaller
lithium cells or batteries as specified in § 173 .185( c ). However, consignments of data loggers
containing lithium batteries that exceed the quantity limits in§ 173.185(c)(3) are subject to the
marking requirements in the HMR. The provisions adopted by the UNSCOE TDG have not
been adopted into the HMR and, therefore, do not apply to your scenario.
When data loggers are in use, they must be in compliance with all applicable Federal Aviation
Administration (FAA) requirements, including those in 14 CFR § 91.21 that address the
operation of portable electronic devices aboard aircraft. Information and guidance to assist with
the compliance of this requirement can be found in Advisory Circular (AC) 91.21-lD, titled Use
of Portable Electronic Devices Aboard Aircraft. For additional information regarding the FAA
requirements, or if you seek an interpretation of whether your particular devices meet the
electronic transmission requirements contained in 14 CFR § 91.21, you may contact the FAA at
the following address:

Dear Mr. Kelley,
COSTHA would like to request a formal letter of interpretation regarding the
provisions for equipment used to track or monitor packages in transport and
adopted by the United Nations Subcommittee of Experts on the Transport of
Dangerous Goods (UNSCOE TDG). Specifically, COSTHA would like to confirm that
equipment used to track or monitor packages are considered part of the packaging
or conveyance. Further, if the devices contain dangerous goods, such as lithium
batteries or fuel cells, then these devices are not subject to regulation as long as
they meet a few minimum requirements.
The Fifty-fourth (54th) session of the United Nations Sub-Committee of Experts on
the Transportation of Dangerous Goods (UNSCOE) was held in Geneva,
Switzerland November 24 through December 4, 2018. The final report of the
meeting includes the adoption of provisions to Paragraph 5.5 of the UN Model
Regulations indicating that equipment used to track or monitor packages are
considered part of the packaging or conveyance.
General Counsel
Richard Schweitzer, PLLC
Data loggers have become an essential tool in preventing spoilage in foods and
pharmaceuticals, theft of medical equipment and other high value items and
maintaining efficiency in all aspects of the supply chain. Most data loggers are
powered by lithium batteries or fuel cells, items currently subject to labeling and
documentation requirements in the 49 CFR.
Many shippers using data loggers as part of their daily operations would not
otherwise fall under the provisions of the Hazardous Materials Regulations (HMR).
While most data loggers are powered by small or excepted batteries and fuel cells,
the number of loggers in a consignment often exceeds the hazard communication
exceptions in § 173.185( c)(3) forcing shippers to label packages and overpacks and
provide adequate instruction to employees preparing the shipments.

<<<PAGE 6>>>

During the UNSCOE meeting, it was agreed that data loggers powered by lithium batteries and
fuel cells do not present a safety risk during transportation. To date, there are no recorded
incidents that were caused by data loggers or indications that data loggers contributed to the
severity of an incident.
We believe the UN Subcommittee made a clarification of the applicability of the regulations to
data loggers with the adoption of Section 5.5.4 of the UN Model Regulations and would like to
confirm PHMSA's position on whether equipment used to track or monitor packages are not
subject to the requirements of the HMR when they are in use or intended for use during
transport.
COSTHA requests PHMSA consider this request expeditiously due to the cost impacts to
industry. If you have any questions, please do not hesitate to contact us.
Sincerely,
~~JP.Ji~
