39 CFR Part 111


Electronic Indicators for the Mailing of Hazardous Materials

AGENCY: Postal ServiceTM.

ACTION: Proposed rule for special standards; invitation to comment.

-----------------------------------------------------------------------

SUMMARY: The Postal Service proposes to provide unique electronic 
service codes and to standardize extra service options for shipments of 
hazardous materials (HAZMAT). If adopted, this proposal would amend 
Publication 52, Hazardous, Restricted, and Perishable Mail (Pub 52) by 
requiring the use of unique service type codes and extra service codes 
within the electronic data submission and tracking barcodes for 
shipments containing HAZMAT provided to the USPS by the mailers in 
their Shipping Services File (SSF). This proposal would standardize the 
acceptance and handling of shipments containing HAZMAT by collecting 
electronic data to create manifests for the Postal Service's air 
carrier suppliers and ensuring these items are handled appropriately 
with regards to the category of HAMZAT contained within the package. 
The Postal Service also proposes to amend the Mailing Standards of the 
United States Postal Service Domestic Mail Manual (DMM) that would 
alter the refund eligibility of Priority Mail Express containing 
hazardous materials.

DATES: Submit comments on or before December 30, 2022.

ADDRESSES: Mail or deliver written comments to the Director, Product 
Classification, U.S. Postal Service, 475 L'Enfant Plaza SW, Room 4446,

SUPPLEMENTARY INFORMATION: The Postal Service proposes to amend 
Publication 52, Hazardous, Restricted, and Perishable Mail (``Pub 
52''), with the provisions set forth herein. While not codified in 
title 39, Code of Federal Regulations (``CFR''), Publication 52 is a 
regulation of the Postal Service, and changes to it may be published in 
the Federal Register. 39 CFR 211.2(a)(2). Moreover, Publication 52 is 
incorporated by reference into Mailing Standards of the United States 
Postal Service, Domestic Mail Manual (``DMM'') section 601.8.1, which 
is incorporated by reference, in turn, into the Code of Federal 
Regulations. 39 CFR 111.1, 111.3. Publication 52 is publicly available, 
in a read-only format, via the Postal Explorer[supreg] website at 
https://pe.usps.com. In addition, links to Postal Explorer are provided 
on the landing page of USPS.com, the Postal Service's primary customer-
facing website, and on Postal Pro, an online informational source 
available to postal customers. If the proposal is adopted, the Postal 
Service will amend Pub 52 and the DMM with the requirements below:
    1. Require PC Postage, eVS, ePostage, and USPS Ship mailers to 
transmit a Shipping Services File (SSF), or Shipping Partner Event File 
(SPEF) to the Postal Service before, or concurrent with, the tendering 
of hazardous materials shipments, and require mailers using USPS 
generated labels (including but not limited to USPS API, WebTools, 
Click-n-Ship, or Merchant Returns Application) to indicate the shipment 
includes hazardous materials at the time of requesting a label.
    2. Require the use of unique Service Type Codes (STCs) for 
hazardous materials packages shipped domestically. At a minimum, 
mailers must use one of six unique STCs, each of which would correspond 
to the hazardous materials contained within a domestic shipment via 
Priority Mail[supreg], First-Class Package Service[supreg], Parcel 
Select[supreg], Parcel Select Lightweight[supreg], and USPS Retail 
Ground[supreg], or, if purchasing extra services, use one of sixteen 
STCs to show the product and extra service used.
    3. Require the use of unique STCs for hazardous materials for 
returns (packages using any of the USPS Return

[[Page 73511]]

products). At a minimum, mailers must use one of eight STCs, each of 
which will correspond with the hazardous materials return shipments via 
Priority Mail Return Service, First-Class Package Return 
Service[supreg], Parcel Return Service, and USPS Ground Return Service, 
or, if purchasing extra services, use one of six STCs to reflect the 
product and extra service used.
    4. Specify that Insurance and Adult Signature will be the only 
domestic Extra Services available on a package containing hazardous 
materials. The Postal Service proposes to provide a unique STC for each 
product without an Extra Service (which would include basic USPS 
``tracking provided'' as a built-in feature of these products), with 
purchases of insurance less than or equal to $500, with purchases of 
insurance over $500, with Signature Requested for Priority Mail 
Express, and with the required use of Adult Signature over 21 for 
Priority Mail Express and Priority Mail shipments of tobacco/Electronic 
Nicotine Delivery System (ENDS) products.
    5. Specify five unique STCs for Priority Mail Express[supreg] 
shipments to identify packages where the mailer is requesting a 
signature waiver, requiring a signature, Adult Signature over 21 (when 
shipping tobacco/ENDS products via PME and PM), purchasing insurance 
less than or equal to $500, or purchasing insurance over $500.
    6. Specify three unique STCs to explicitly identify Division 6.2, 
Infectious Substances, returned through the Postal Service network 
using any USPS Return Service product.
    7. Provide unique Extra Service Codes (ESC) to identify categories 
of hazardous materials with specific relevance to segregation, 
handling, and identification in the Postal Service network.
    8. Encourage adoption of the Postal Service's recommendation to add 
two (2) supplemental GS1-DataMatrix (2D) IMpbs to shipping labels to 
improve package visibility; one in the address block to the left of the 
Delivery Address and one in the lower right corner of the shipping 
label.
    9. Provide for the optional use of hazardous materials electronic 
indicators from the date of publication of the final rule until January 
21, 2023, and, if the final rule is adopted, to require their use by 
April 30, 2023.

Overview

    Due to the rapid expansion of eCommerce, the United States Postal 
Service[supreg] (Postal Service[supreg]) has encountered a significant 
increase in the number of hazardous material shipments being entered 
into the mailstream. Materials such as lithium batteries, flammable 
liquids, flammable gases, non-flammable compressed gases, and corrosive 
cleaning solutions that were typically purchased through brick-and-
mortar establishments are now routinely being purchased online and 
shipped to their destination. This increase in hazardous material 
volume has brought with it a proportional increase in instances of 
improper labelling and packaging, use of ineligible shipping services, 
and an increase in safety related incidents in Postal Service 
facilities. These incidents have increased risks to Postal Service 
employees, customers, and business suppliers, especially risks related 
to personal safety/property damage, and resulted in millions of dollars 
in losses.
    The Postal Service relies heavily on commercial cargo and passenger 
aircraft to transport mail in circumstances where the use of ground 
transportation is insufficient to meet its service standards or is 
otherwise operationally or financially impracticable. With regard to 
the transportation of hazardous materials, commercial air carriers 
observe requirements promulgated by the Federal Aviation Administration 
(FAA), and the International Civil Aviation Organization (ICAO).
    In accordance with FAA regulations, commercial air carriers are 
required to develop and maintain a Safety Management System (SMS). In 
applying the safety risk management concept of their respective SMS, 
air carriers conduct a systemic analysis to identify hazards and then 
develop and maintain processes to analyze the safety risks associated 
with the hazards identified. This process requires air carriers to 
acquire data with respect to their operations, products, and services, 
to monitor the safety performance of their operations, and to conduct 
and update their risk assessments. Previously, the Postal Service 
tendered mail, including packages containing both non-hazardous and 
marked hazardous materials, to its contracted air carriers in sacks. 
Due to the ``sacking'' of marked hazardous materials from the Postal 
Service, air carriers were often unaware of the specific marked 
hazardous materials they were accepting and transporting. Without this 
information, air carriers were unable to accurately define and address 
the risks associated with the mail. To address these issues, and 
several others related to hazardous materials shipments, the Postal 
Service promulgated an interim final rule specifying that mailers must 
separate hazardous materials from other mail when tendering to the 
Postal Service. 87 FR 34197. In a separate final rule being published 
today, the Postal Service promulgated as a final rule the changes to 
Pub 52, with some alterations from the interim final rule. The current 
proposal complements the effective implementation of both the interim 
final rule and the more recent final rule, but also is part of a 
broader effort to increase safety and security when hazardous materials 
are transported through the mail.

Proposal

    To enhance its ability to make knowledgeable decisions regarding 
the handling and disposition of hazardous materials shipments in its 
networks and better leverage the use of operational processes to 
properly segregate and tender these items, the Postal Service proposes 
to require mailers to identify and categorize their hazardous materials 
shipments through the use of specified electronic indicators.
    The Postal Service expects to use these indicators to capture 
details about the categories, volume, and weight of the hazardous 
materials contained in packages tendered to its contracted 
transportation providers, which would ensure that both the Postal 
Service and its contracted transportation providers have the required 
information to be able to handle these packages in a safe and 
operationally efficient manner. These HAZMAT-specific indicators will 
be required regardless of whether the mailpieces are entered at origin 
or in connection with destination entry.
    The Postal Service has enhanced its operational capability to 
provide piece-level tracking and visibility through the use of the 
Intelligent Mail Package Barcodes (IMpb[supreg]). These barcodes can be 
scanned by automated processing equipment and Intelligent Mail scanning 
devices. Today, mailers are required to encode certain information into 
the barcode structure of the IMpb through the use of STCs and to encode 
additional information into a USPS-Approved SSF/SPEF through the use of 
Extra Service Codes (ESCs). As part of current procedures under Postal 
Service Publication 199, mailers tendering commercial packages to the 
Postal Service are required to accurately encode their IMpb barcodes 
for each package and supply the Postal Service with a complete SSF/SPEF 
when entering their packages into the Postal Service's network.
    The Postal Service is committed to improving package visibility by 
increasing the volume and quality of scan data that is collected within 
its processing environment. Extreme curvature, fold-overs, and creased

[[Page 73512]]

shipping labels on soft packs and irregularly shaped parcels often 
distort the current/traditional one-dimensional GS1-128 IMpb barcode to 
an extent that the barcode becomes unreadable resulting in no-reads. 
This reduces overall package visibility to the customer and may require 
that the piece be re-run or manually sorted. In an effort to improve 
processing efficiency and improve package visibility, the Postal 
Service will recommend adding two (2) supplemental GS1-DataMatrix (2D) 
IMpbs to shipping labels: one in the address block to the left of the 
Delivery Address and the other in the lower right corner of the 
shipping label. The Postal Service may require this practice in the 
future. For more information on the GS1-DataMatrix (2D) IMpbs, mailers 
can view GS1 (2D) information and find barcode specifications at: 
https://www.gs1.org/docs/barcodes/GS1_DataMatrix_Guideline.pdf and 
https://postalpro.usps.com/shipping/impb/2d-impb-guide.
    As a related matter, the Postal Service proposes to amend the 
Mailing Standards of the United States Postal Service Domestic Mail 
Manual (DMM) that would alter the refund eligibility of Priority Mail 
Express containing hazardous materials. Given that shipments containing 
HAZMAT may have to be processed differently than if they did not 
contain HAZMAT. As a result, the Postal Service proposes that refunds 
for domestic Priority Mail Express would not be available for shipments 
containing live animals or hazardous materials and the item is 
delivered or delivery was attempted within 3 days of the date of 
mailing.

Restriction of Extra Services

    The Postal Service proposes to restrict the Extra Service options 
available for shipments of regulated hazardous materials, including 
restrictions on Adult Signature over 21 (used when regulations require 
restricted delivery to adults aged 21 years and older for tobacco and 
ENDS shipments), insurance over and under $500 for most mail classes or 
products, and insurance over and under $500 in addition to waiver of 
signature for Priority Mail Express. The Postal Service is proposing 
these additional restrictions to reduce the complexity for mailers 
complying with the requirements in this Federal Register Notice. The 
Postal Service expects the demand for the variety of Extra Services 
covered under this proposed restriction to be low enough for shippers 
of hazardous materials to generally be of minor concern.

PC Postage, eVS, USPS Ship, and ePostage Users or Users of USPS-
Generated Labels (USPS APIs, WebTools, Click-n-Ship, MRA)

    The generation of the flight-specific air carrier manifests and the 
other operational enhancements proposed in this Federal Register Notice 
would be possible only when the information is included in a mailer's 
SSF/SPEF and is made available to all Postal Service systems in a 
timely fashion. It is for this reason that the Postal Service is 
proposing to require impacted mailers to transmit an approved SSF/SPEF 
before, or concurrent with, the physical tendering of regulated 
hazardous materials shipments to the Postal Service regardless of the 
postage payment method used. In addition to the other postage payment 
methods, this requirement would extend to mailers using electronic 
payment systems (PC Postage, eVS, ePostage, or USPS Ship). 
Additionally, any mailer using a USPS generated label (including but 
not limited to USPS API, WebTools, Click-n-Ship, or Merchant Returns 
Application) would indicate before label generation that the shipment 
includes hazardous materials.

Legacy Postal Meters and Hard Copy Mailers

    To ensure electronic information for all hazardous materials 
shipments is available and provided to the Postal Service concurrent 
with the induction of each shipment into the Postal Service's network, 
the Postal Service proposes to restrict shipments of hazardous 
materials from mailers using postage meters not capable of 
electronically transmitting transactional data to the Postal Service, 
mailers submitting paper postage statements, and any other mailers who 
may still be using legacy package barcodes. The Postal Service urges 
these mailers to transition to newer systems or to bring their 
hazardous materials to a Postal Service retail unit for induction.

Service Type Codes and Extra Service Codes for Hazardous Materials

    The Postal Service proposes to specify six unique required STCs and 
an optional sixteen STCs to correspond with each product and extra 
service used to identify the hazardous materials contained in domestic 
originating shipments via Priority Mail Service, First-Class Package 
Service[supreg], Parcel Select, Parcel Select Lightweight, and USPS 
Retail Ground Service. The optional STCs would provide a unique STC for 
each product without an Extra Service, requests for insurance less than 
or equal to $500, requests for insurance over $500, Signature Requested 
for Priority Mail Express, and Adult Signature over 21 for Priority 
Mail Express and Priority Mail. The Postal Service also proposes to 
specify eight unique required STCs and an optional six STCs to reflect 
the product and extra service used, each to correspond to hazardous 
materials return shipments via Priority Mail Return Service, First-
Class Package Return Service[supreg], Parcel Return Service, and USPS 
Ground Return Service. The eight required STCs specify unique STCs for 
each product, and specify unique STCs to explicitly identify Division 
6.2, Infectious Substances, while the optional STCs would correspond to 
the Extra Service options described above for domestic shipments 
returned through the Postal Service network using each of these return 
services. The Postal Service proposes unique STCs to identify Division 
6.2, Infectious Substances, because hazardous materials in this 
category are the most commonly shipped hazardous materials through the 
Postal Service network via a return service. Additional visibility into 
these shipments would be beneficial to the Postal Service reducing 
incidents related to the mailing of hazardous materials.
    The Postal Service proposes to provide unique ESCs to identify 
specified categories of hazardous materials with specific relevance to 
segregation, handling, and identification in Postal Service networks. 
The Postal Service plans to specify approximately 23 ESCs, each to 
identify a category of hazardous materials that is associated with 
specific restrictions, packaging, and markings requirements, and for 
some ESCs, restrictions in air transportation. Included among the 
proposed categories to be assigned with a specific ESC, and intended 
for air transportation are:

 Air Eligible Consumer Commodity/Limited Quantity
 Air-eligible Ethanol
 Excepted Quantity
 Division 5.1, Oxidizer
 Division 5.2, Organic Peroxide
 Division 6.1, Toxic Material (Packaging Instruction 6B)
 Class 8, Corrosive
 Class 8, Nonspillable battery
 Class 9, Dry Ice
 Class 9, Magnetized Material
 Class 9, Lithium Battery (marked)
 Class 9, Lithium Battery (unmarked)

    The Postal Service has also specified one proposed ESC to indicate 
a shipment with hazardous materials to be used when requesting a USPS

[[Page 73513]]

generated label from USPS APIs or WebTools. Additionally, the Postal 
Service has specified proposed ESCs to correspond with categories of 
hazardous materials shipments intended for ground transportation, which 
will be available in Appendix G of Pub 52.
    The Postal Service expects to have these STCs and ESCs available 
for optional use by mailers before the end of the 2022 calendar year. 
If the final rule is adopted, the Postal Service intends to require STC 
adoption by April 30, 2023. The use of ESCs in domestic mail and GS1 
DotMatrix (2D) barcodes would remain optional for mailers for the 
foreseeable future. The use of the appropriate STC and ESC is 
contingent upon the mailability of the hazardous material. Mailers must 
adhere to the packaging instructions in Pub 52 for specific hazardous 
materials being shipped in order to assess mailability prior to 
finalizing the shipment.

International Shipments

    Tracking numbers for international packages include the use of an 
IMpb and would not have unique STCs for hazardous materials. However, 
international mailpieces containing hazardous materials/Dangerous Goods 
(DG) ((DG) is an international term used to identify hazardous 
materials) would be required to utilize the appropriate ESC for the 
category of hazardous materials/DG in the SSF/SPEF used by the mailer 
and transmitted to the Postal Service. The Postal Service proposes to 
require mailers to include the hazardous materials/DG ESC applicable to 
the category of material being shipped. In accordance with Mailing 
Standards of the United States Postal Service, International Mail 
Manual (IMM[supreg]) part 135, only three categories of hazardous 
materials/DG are permitted in international mail. Hazardous materials/
DG permitted in international mail are restricted to specified subsets 
of the following DG classes:

 Division 6.2, Infectious Substances (permitted only by 
authorization from Product Classification, USPS[supreg] Headquarters)
 Class 7, Radioactive Materials
 Class 9, Lithium Batteries installed in equipment (unmarked)

    The Postal Service would provide access to the ESCs applicable to 
these hazardous materials categories for use with international mail.

Systems Enhancements

    To provide greater visibility into the quantities, weights, and 
categories of hazardous materials being tendered to the Postal 
Service's contracted air carriers, the Postal Service plans to use the 
data from the STCs and ESCs to improve its identification of hazardous 
materials/DG shipments, ensure proper assignment of these shipments to 
the proper mode of transportation, acquire better data on what 
hazardous materials/DG are transiting its system, and provide increased 
safety to customer, employees, contractors, and shippers.
    These electronic indicators would also provide Postal Service 
operations personnel with the ability to identify packages containing 
hazardous materials/DG and the categories under which they fall. This 
additional information would allow the Postal Service to separate or 
handle such hazardous materials/DG packages as necessary to meet 
operational requirements and allow Postal Service operations to affix, 
when necessary, the applicable markings to a postal receptacle 
containing hazardous materials/DG.

Enforcement

    If this proposal is adopted, the United States Postal Inspection 
Service[supreg] (USPIS[supreg]) expects universal compliance by mailers 
following a reasonable period of time to communicate the new 
requirements to mailers and postage payment providers, and for them to 
make the necessary changes to their systems. Following the 
implementation period, USPIS[supreg] intends to enforce these new 
requirements using its civil penalty authority under 39 U.S.C. 3018 
and/or 39 CFR 233.12(f).
    The Postal Service is revising the Priority Mail Express refund 
policy in DMM subsection 604.9.5.5 to not allow a refund if the 
shipment contains hazardous materials and was delivered or delivery was 
attempted within 3 days of the date of mailing.
    Although exempt from the notice and comment requirements of the 
Administrative Procedure Act (5 U.S.C. 553(b), (c)) regarding proposed 
rulemaking by 39 U.S.C. 410(a), the Postal Service invites public 
comment on the following proposed revisions to Mailing Standards of the 
United States Postal Service, Domestic Mail Manual (DMM), incorporated 
by reference in the Code of Federal Regulations. See 39 CFR 111.1.
    We will publish an appropriate amendment to 39 CFR part 111 to 
reflect these changes.
    The Postal Service also proposes to adopt the following changes to 
Publication 52, Hazardous, Restricted, and Perishable Mail, 
incorporated by reference into the DMM, section 601.8.1, which is 
further incorporated by reference in the Code of Federal Regulations. 
39 CFR 111.1, 111.3. Publication 52 is also a regulation of the Postal 
Service, changes to which may be published in the Federal Register. 39 
CFR 211.2(a).

323.1 Electronic Service Type and Extra Service Codes

    Mailers tendering packages containing hazardous materials to the 
Postal Service must use a unique Service Type Code (STC) for domestic 
outbound and return packages that correspond to the appropriate product 
being shipped (i.e., Priority Mail[supreg], First-Class Package 
Service[supreg], Parcel Select[supreg], Parcel Select 
Lightweight[supreg], and USPS Retail Ground[supreg]). The STC is 
required regardless of whether the mailpieces are entered at origin or 
for destination entry. If purchasing an eligible extra service, mailers 
must use the STC indicating the product and extra service in 
conjunction with the appropriate Extra Service Code (ESC). Extra 
services permitted with hazardous materials mailings are:

a. Adult Signature
b. Insurance less than or equal to $500
c. Insurance over $500
d. Signature Requested for Priority Mail Express
e. Adult Signature over 21 for Priority Mail Express (tobacco/
Electronic Nicotine Delivery System (ENDS) products)
f. Adult Signature over 21 for Priority Mail (ENDS products)

    A list of HAZMAT STCs and ESCs can be found in Appendix G and Pub 
199.

323.2 Additional GS1 DotMatrix (2D) IMpb

    In addition to including the appropriate STC in the one-dimensional 
GS1-128 IMpb barcode on the address label, the Postal Service 
recommends adding two (2) supplemental GS1-DataMatrix (2D) IMpbs to 
shipping labels. One in the address block to the left of the Delivery 
Address and one in the lower right corner of the shipping label.

    Note:  while currently this is a recommended practice, the 
Postal Service may undertake to make this requirement mandatory in 
the future. For more information on the GS1-DataMatrix (2D) IMpbs, 
mailers can view GS1 (2D) information and find barcode
