**I. Introduction**
On April 8, 2026, the Postal Service filed a notice of rates not of general applicability for Inbound Letter Post Small Packets (Inbound E-format Letter Post), and a notice of minor classification changes to the *Mail Classification Schedule* (MCS) concerning Inbound Letter Post Small Packets, both of which will take effect on January 1, 2027. [^1] The Postal Service requests that the Commission favorably review the proposed rates so that the Postal Service may submit the rates to the Universal Postal Union (UPU) before the May 1, 2026 deadline. Notice at 12. The Postal Service also requests that the Commission adopt the proposed minor classification changes to the MCS. *Id.*
[^1] Notice of the United States Postal Service of Rates Not of General Applicability for Inbound E-Format Letter Post, Notice of Minor Classification Changes, and Application for Non-Public Treatment, April 8, 2026, at 1 (Notice).
**II. Contents of Filing**
In its Notice, the Postal Service proposes new rates for the Inbound Letter Post Small Packets product. *Id.* at 3-4. Under the Universal Postal Convention (as amended by the UPU Dubai Congress in 2025), designated operators must submit any self-declared inbound E-format rates that would take effect on January 1, 2027 to the UPU International Bureau (IB) by May 1, 2026. [^2] The Postal Service states that the proposed rates comply with 39 U.S.C. 3633. Notice at 7. To support its proposed Inbound Letter Post Small Packets rates, the Postal Service filed the proposed rates, a copy of the certification required under 39 CFR 3035.105(c)(2), and a redacted copy of Governors' Decision No. 19-1. *Id.* at 5-6; *see id.* Attachments 2-4. The Postal Service also filed redacted financial workpapers. Notice at 6. In addition, the Postal Service filed an unredacted copy of Governors' Decision No. 19-1, the unredacted new rates, and unredacted financial information under seal. *Id.* at 5-6. The Postal Service also provided an application for non-public treatment of materials filed under seal filed pursuant to 39 CFR part 3011. *Id.* at 5; *see id.* Attachment 1.
[^2]*Id.* at 3; Universal Postal Union, Decisions of the 2025 Dubai Congress, at 49, Second Additional Protocol to the Universal Postal Convention, Article XV (Article 29 amended), paragraph 1.4, available at *https://www.upu.int/UPU/media/upu/files/aboutUpu/acts/07-actsAndOtherDecisions2025DubaiCongress/2025DubaiCongressDecisionsEn.pdf* . (Decisions of the 2025 Dubai Congress).
The Postal Service also proposes minor classification changes to various MCS sections concerning Inbound Letter Post Small Packets, pursuant to 39 CFR 3040.190. *Id.* at 7-8. The Postal Service explains that the proposed changes should result in the MCS more accurately representing the Postal Service's offerings as of January 1, 2027, and they are also mandated by amendments to the Universal Postal Convention that were adopted by the UPU Dubai Congress in September 2025. *Id.* at 8. These UPU amendments require that, “effective January 1, 2027, the `E' format of UPU letter post shall consist only of `small packets' and not also `bulky letters.' [^3] Therefore, the Postal Service proposes “to remove the `Bulky Letters' term from the product name in MCS sections 2000, 2300.2, 2340.1.1, 2340.2, 2340.3, 2340.4, 2515.10.1, 2515.10.2, and 2615.4.1.” Notice at 8; *see id.* Attachment 5. The Postal Service also proposes to make two other changes for consistency, by replacing “prices” with “rates” in MCS section 2340.6, and by adding a new subsection “f” to MCS section 2340.1.1 to acknowledge that the product is subject to the UPU Convention and its Regulations. Notice at 8-9; *see id.* Attachment 5. The Postal Service states that the proposed changes are minor instead of material in nature. Notice at 9-11. The Postal Service submits the proposed changes to the MCS in legislative format in Attachment 5 to the Notice. *Id.* at 8; *see id.* Attachment 5.
