In the field of consumer electronics and medical devices, button or coin batteries are widely used due to their small size, portability, and high energy density. However, the safety performance and quality control of these batteries have been the focus of manufacturers.

As the e-bike market continues to grow, lithium-ion batteries as core components are facing more stringent quality and safety requirements. The implementation of GB/T 36972-2018 \"lithium-ion battery for electric Bicycles\" national standard provides a clear technical specification and development direction for manufacturers. This paper analyzes the key impact of this standard from the perspective of production.

In the process of TWS headphone export to the Korean market, KC certification, as a mandatory access standard, has become a technical threshold that manufacturers must cross. The certification system implemented by the Korean Institute of Technology and Standards (KATS) puts forward strict requirements for the safety and electromagnetic compatibility of lithium batteries, which directly affects whether the products can legally enter the circulation channels in South Korea.

In the context of the accelerated integration of the global electronic products trade, the competition in the TWS headphone industry chain has shifted from a single product performance to a full-system certification layout. As a core component of lithium batteries, its CB certification is becoming a key threshold for manufacturers to break through the international market.

In the TWS headphone industry chain, battery safety is always the core lifeblood of product quality. As a passport to connect to the global market, UN38.3 certification is not only a simple compliance requirement, but also an intuitive reflection of the technical strength of the manufacturer. This mandatory standard, established by the United Nations Dangerous Goods Transport Recommendation, builds a safety line through eight rigorous test items, from vibration shock to extreme temperature changes, to verify the reliability of batteries in the transport process.

In the TWS headphone industry chain, the battery is a core component, and its compliance directly affects the market access and brand reputation of the product. According to data from the State Administration for Market Regulation, consumer complaints caused by battery problems in 2023 accounted for 23.6%, most of which involved lack of certification. For manufacturers, 3C certification is not only a legal entry threshold, but also a key line of defense to build market competitiveness.

On January 13th, 2025, the working group of pollution prevention standards for electrical and electronic products in China issued an explanatory notice on the coordinated implementation of the two standards, namely, Requirements for Labeling of Hazardous Substances Restricted in Electrical and Electronic Products (SJ/T11364-2024) and Requirements for Limited Substances in Electronic and Electrical Products (GB/T26572-2011).

On April 25th, 2024, the Ministry of Information and Communication (MIC) of Vietnam issued an announcement and a draft technical regulation QCVN 134:2024/BTTTT. The draft technical regulations stipulate the limits and methods for measuring the specific absorption rate (SAR) of mobile phones, which will be applicable to entities engaged in the manufacture, import, trade and operation of mobile phones in Vietnam.
