On June 27, 2025, the European Commission published Regulation (EU) 2025/718 in its Official Gazette (OJEU), formally revising the limits for perfluorooctane sulfonic acid (PFOS), its salts and related compounds in Annex I of the EU Persistent Organic Pollutants (POPs) Regulation (EU) 2019/1021. The revised regulations will take effect on July 17, 2025 and will be implemented from December 3, 2025.

In the battery production and sales process, many enterprises encounter such a problem: the same model of battery has passed the CCC certification, and the certification report clearly states a specific inkjet coding format, but downstream customers have put forward different inkjet coding format requirements. The core indicators such as product parameters and performance have not changed. Only the inkjet coding style is different. In this case, can the inkjet coding format be adjusted? The answer is affirmative.

In the production and circulation of battery products, CCC certification is an important threshold to ensure product safety. However, many enterprises encounter a thorny problem after completing the certification: when the battery pack has been assembled into a semi-finished product, how should the 3C marking of the individual battery cells be handled? As a professional certification service provider, Zhongrenlianke has provided a clear solution to this difficult problem.

In the production, use and circulation of battery packs, the standardized marking of warning instructions is of vital importance. It not only relates to the compliance of the product, but also directly affects the safety of users\' use. However, many enterprises and users have doubts about the relevant requirements for battery pack warning instructions. As a professional certification service provider, Zhongrenlianke is here to answer two common questions for everyone.

In the certification process of lithium-ion batteries and related products, the requirements for key components in the CCC type test report are of vital importance, directly affecting the compliance and effectiveness of the certification. As a professional certification service provider, China Certification Union Technology Co., Ltd. will provide you with an in-depth interpretation of the relevant core points.

In the international certification chain for battery products, the transition from CB certification to KC certification is an efficient path to enter the South Korean market. Compared with a brand-new application, using the CB certification foundation can significantly shorten the certification cycle, but the specific time limit still depends on the completeness of the document preparation.

In the international trade of battery products, converting from CB certification to KC certification is a crucial step to enter the South Korean market. Unlike other certifications, KC certification has strict restrictions on the certificate holder - only Korean importers or production plants are allowed to be the certificate holders. This premise determines that the preparation of materials must simultaneously meet the compliance requirements of both China and South Korea. The following is a detailed summary of the essential materials and precautions for you.

In the international trade of battery products, the change of KC certification address is an important link for enterprises to operate in compliance. The accuracy of address information not only affects the validity of the certificate, but also directly relates to the product\'s circulation qualification in the South Korean market. The following is a detailed analysis of all the materials required for the KC address change and the key points to note.
