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.
With the growing demand for electric toys in the global market, manufacturers must ensure that their products meet the requirements of CE certification when entering the European market. CE certification is not only a recognition of product quality, but also a necessary pass to enter the European market.
In the ecosystem of electronic products, charging heads play a crucial role. As a bridge connecting the power supply and the equipment, its quality is directly related to the safety of the user and the service life of the equipment. Therefore, the manufacturer must pay attention to the quality control of the charging head, and through a professional quality inspection report to ensure that the product meets the standards.
