 Date: July 29 th , 2026 Federal Communications Commission Office of Engineering and Technology Laboratory Division 7435 Oakland Mills Rd. Columbia MD 21046 Subject: Request for Confidentiality Ref: FCC ID numbers To whom it may concern: Pursuant to the provisions of Sections 0.457 and 0.459 of the Commission’s rules (47 CFR §§ 0.457, 0.459), Apple Inc. hereby requests confidential treatment for documents filed with the Commission in connection with the application for equipment authorization referenced above. Long-Term Confidentiality Apple Inc. requests that the Commission withholds the following documents from public viewing indefinitely: • Block Diagrams • Electrical Schematic Diagrams • Technical Descriptions, Product Specifications • Antenna Locations These documents reveal detailed technical and design information that is protected by Apple Inc. as confidential and proprietary trade secrets. This information has been disclosed to those required to maintain its confidentiality and is not customarily disclosed to the public even after commercial release of a device. As a result, disclosure of this information by the Commission would harm Apple Inc. by giving competitors an unfair advantage even after commercial release of the device. Short-Term Confidentiality In addition to the above mentioned documents, pursuant to Public Notice DA 04-1705 of the Commission’s policy, in order to comply with the marketing regulations in 47 CFR §2.803 and the importation rules in 47 CFR §2.1204, while ensuring that business sensitive information remains confidential until the actual marketing of newly authorized devices, Apple Inc. requests that the Commission withholds the following documents from public viewing for one hundred eighty days after the date the grant of equipment authorization is issued: • External Photographs • Internal Photographs Model(s)FCC ID A3439 BCG-A3439 A3440 BCG-A3440 A3531 BCG-A3531 A3532 BCG-A3532 Apple Inc. One Apple Park Way Cupertino, CA www.apple.com  • Test Setup Photographs • User Manual These documents reveal technical and design information that has not been publicly disclosed in marketing materials and is protected by Apple Inc. as confidential and proprietary trade secrets. This information has been disclosed to those required to maintain its confidentiality and is not customarily disclosed publicly prior to the commercial release of the device. As a result, disclosure of this information by the Commission prior to commercial release would harm Apple Inc. by giving competitors an unfair market advantage. Apple Inc. believes the period of confidentiality requested is necessary to protect the information until the commercial release of a device. It is our understanding that measurement test reports and FCC ID label format cannot be granted as confidential documents and this information will be available for public review once the grant of equipment authorization is issued.
