KARIYA, JAPAN, September 29, 2025 – (JCN Newswire via SeaPRwire.com) – DENSO CORPORATION (Headquarters: Kariya City, Aichi Prefecture; President: Shinnosuke Hayashi, hereinafter referred to as “DENSO”) and TÜV Rheinland Japan, Ltd. (Headquarters: Yokohama City, Kanagawa Prefecture; President: Kunihiro Okamoto, hereinafter referred to as “TÜV Rheinland Japan”) are pleased to announce that DENSO and TÜV Rheinland Japan have signed a memorandum of understanding in order to realize sustainable manufacturing for industrial products, including batteries, and to promote the Digital Product Passport*1 (hereinafter referred to as “DPP”), which contributes to the efforts.
In recent years, there has been a strong demand across entire society for achieving carbon neutrality and transitioning to a circular economy that circulates resources within the economic system, therefore it has been accelerating efforts to create sustainable products. As a part of these efforts, the EU implemented the Ecodesign Regulation*2 in July 2024, introducing a new framework that mandates environmental considerations from the design stage of products. Under this regulation, the introduction of the DPP, which electronically records information such as the manufacturer, materials used, CO2 emissions, and recyclability, is required.
Furthermore, from February 2027, under the European Battery Regulation*3, the introduction of the “Battery Passport” for battery products, including automotive and industrial batteries, is scheduled to become mandatory as the first use case of the DPP.
To support compliance with these regulations, DENSO is developing an application for the Battery Passport and, in February 2025, became the first Japanese company to obtain EcoPass certification from Catena-X*4.
In addition, TÜV Rheinland Japan is a third-party certification body that provides testing, certification, inspection, and evaluation services related to product safety and quality, and always offers the latest evaluation services in various industrial fields.
DENSO and TÜV Rheinland Japan have now agreed to comprehensively collaborate as strategic partners on verification and certification services for compliance with the Ecodesign Regulation and the European Battery Regulation, as well as on DPP initiatives.
Collaboration Details
- The two companies will cooperate in the development of DPP and related business services, including the Battery Passport.
- The two companies will collaborate on regulatory compliance and client support related to the Battery Passport.
- TÜV Rheinland Japan will provide third-party verification and certification services for DENSO’s Battery Passport application.
- The two companies will jointly create technical documentation related to the Battery Passport for clients.
Through extensive collaboration, DENSO and TÜV Rheinland Japan will promote DPP initiatives, including the Battery Passport, and contribute to the realization of a sustainable society.
