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.

The CB certification system implemented by the International Electrotechnical Commission (IECEE) has built an access network covering 54 countries for lithium battery products through the mutual recognition mechanism of "one test, global recognition". For TWS headphone battery manufacturers, obtaining this certification not only means the authoritative endorsement of safety performance, but also represents the elimination of repeated testing in the target market. Taking the European CE certification as an example, enterprises holding CB certificates can reduce the certification cycle by about 40%, significantly reducing the cost of testing.

The certification process focuses on three technical dimensions: the reliability verification of the cell overcharge/overdischarge protection system, the stability testing of the thermal runaway protection design, and the mechanical shock resistance test in the transport environment. Actual cases show that some enterprises ignore the compatibility test of the soft pack battery sealing process, resulting in repeated failures in the IP protection level verification link. It is recommended that manufacturers introduce laboratories with CBTL qualification at the early stage of certification to carry out structural design and testing verification simultaneously, which can shorten the rectification cycle by more than 30%.

It is worth noting that the current major importing countries are gradually upgrading certification requirements. The new battery regulations of the EU have clearly included cycle life indicators into the evaluation system, and the US market has proposed more stringent testing standards for wireless charge-discharge compatibility. Manufacturers who complete the CB certification layout in advance can not only quickly respond to changes in regulations, but also optimize product design through the technical data accumulated in the certification process, forming a differentiated market competitive advantage.

For enterprises planning to expand overseas markets, it is recommended to establish a certification strategy map: CB certification as a basic framework, simultaneous planning of the target market extension certification (such as PSE in Japan, KC in South Korea). This three-dimensional certification layout can shorten the time to market for new products to 60% of the regular process, especially for ODM projects that need to be listed in multiple countries simultaneously.
