We have received requests for a 60- 
day extension of the comment period for 
the color additive petition. We have considered these requests and are extending the comment period for the color additive petition until September 1, 2023.

POSTAL SERVICE 
39 CFR Part 111 Intelligent Mail Package Barcode 
Compliance Quality 
AGENCY : Postal ServiceTM. 
ACTION : Proposed rule. 
SUMMARY : The Postal Service is 
proposing to amend Mailing Standards of the United States Postal Service, Domestic Mail Manual (DMM
®) to add 
an additional Intelligent Mail®package 
barcode (IMpb®) validation under the 
‘‘Barcode Quality’’ category. 
DATES : Submit comments on or before 
July 28, 2023. 
ADDRESSES : Mail or deliver written 
comments to the Director, Product Classification, U.S. Postal Service, 475 L’Enfant Plaza SW, Room 4446, Washington, DC 20260–5015. If sending comments by email, include the name and address of the commenter and send to PCFederalRegister@usps.gov, with a 
subject line of ‘‘IMpb Compliance Barcode Quality’’. Faxed comments are not accepted. 
You may inspect and photocopy all 
written comments, by appointment only, at USPS
®Headquarters Library, 
475 L’Enfant Plaza SW, 11th Floor North, Washington, DC 20260. These 
records are available for review on Monday through Friday, 9 a.m.–4 p.m., by calling 202–268–2906. FOR FURTHER INFORMATION CONTACT :

SUPPLEMENTARY INFORMATION : 
Confidentiality 
All submitted comments and 
attachments are part of the public record and subject to disclosure. Do not enclose any material in your comments that you consider to be confidential or inappropriate for public disclosure. 
In section 204.2.1.8, IMpb Compliance 
Quality Thresholds, the ‘‘Barcode 
Quality’’ compliance category checks that the barcode in the manifest passes two critical validations: 1. Valid and Certified Mailer ID in the label that is in Program Registration/Online Enrollment, 2. IMpb must be unique for 120 days. 
The Postal Service relies on the 
accuracy of the IMpb, and the data contained within the barcodes, including Service Type Codes (STCs). 
The Postal Service is proposing to add 
a third validation under ‘‘Barcode Quality’’ that will require that an IMpb must include a valid, unique 3-digit STC that accurately represents the mail class, product, and service combination on the physical label affixed to the package. Additionally, the IMpb on the package must also correspond with electronic package level details and Extra Services Code(s) contained within the Shipping Services File (SSF). Any variance in the data presented in the electronic submission of a parcel or a variance with the physical aspect of the label affixed to a parcel presented for mailing will be subject to the IMpb noncompliance fee if a mailer falls below the 98 percent threshold. 
The Postal Service is proposing to 
implement this change effective October 1, 2023. 
We believe the proposed revision will 
ensure the IMpb quality enabling the Postal Service to provide customers with a more efficient mailing experience. 
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.
