In the current era of rapid technological development, polymer batteries, with their advantages of high energy density, light weight, and good safety performance, are widely used in various electronic products such as smart phones, laptops, and power tools, becoming an important \"energy heart\" that supports modern life. However, to ensure the quality and safety of such battery products, CCC certification has become a crucial step for them to enter the market.

In the current era of rapid technological development, lithium-ion batteries, with their advantages such as high energy density and long cycle life, are widely used in portable electronic products, electric vehicles, energy storage devices and other fields, becoming an indispensable part of modern life. However, with the rapid expansion of its market size, products of varying quality have flooded the market. Some inferior batteries have caused safety accidents such as fires and explosions, seriously threatening the lives and property of consumers. Against this backdrop, the CCC certification system for lithium-ion batteries emerged, aiming to regulate the market and ensure safety.

In the era of vigorous technological development, square batteries, with their unique advantages, have been widely applied in numerous fields. However, before entering the market, it must cross the crucial threshold of CCC certification. So, what exactly is CCC certification? What significance does it have for square batteries? Let\'s explore it in depth together.

In the current era of rapid technological development, pouch batteries, with their lightness, thinness, high energy density and good flexibility, are widely used in various electronic devices and have become an important force driving the development of the industry. However, as its application scenarios continue to expand, security issues have become increasingly prominent. To safeguard consumers\' rights and interests and regulate market order, the CCC certification for pouch batteries has emerged.

Effective September 1, 2026, the new battery consumption tax policy officially comes into force. Under this policy, phased taxation is reinstated for mature batteries with large‑scale industrial application, such as lithium‑ion accumulators and all‑vanadium redox flow batteries. Cutting‑edge technical routes including sodium‑ion batteries, solid‑state batteries, fuel cells, as well as perovskite and tandem photovoltaic batteries are eligible for phased consumption tax exemption valid from September 1, 2026 to December 31, 2028.

With sodium‑ion batteries and lithium‑sodium hybrid batteries gradually achieving industrial‑scale application, major revisions have been rolled out for international aviation dangerous goods regulations. IATA Dangerous Goods Regulations (DGR) Edition 68 (2027 Version) has been officially released. This regulation incorporates all revisions of the ICAO Technical Instructions 2027‑2028 and revisions from the IATA Dangerous Goods Committee. The new rules not only complete the compliance framework for air transportation of new‑type batteries, but also significantly tighten clauses governing batteries carried by passengers. They will exert direct impacts on battery manufacturers, foreign‑trade exporters, cross‑border logistics providers and airlines. This edition is scheduled to enter into force on January 1, 2027.

Driven by the vigorous growth of energy‑storage, power‑tool and portable power‑supply industries, overseas market demand for 18650 lithium‑ion batteries keeps rising. Many domestic factories deliver well‑made products yet stumble at compliance thresholds: goods get detained upon arrival at foreign ports, key customers reject orders, and hard‑won business deals are blocked by certification requirements. Numerous practitioners have heard of CB certification but are unclear about its positioning and tangible benefits after acquisition.

As the energy storage equipment, portable energy storage and supporting power supply industries keep booming, market demand for lithium iron phosphate (LFP) batteries continues to surge. Many enterprises have completed product R&D and production yet get stuck at the market access stage. In practice, some manufacturers lack sufficient understanding of mandatory certification and encounter troubles such as product delisting and seizure or rejection in project bidding even before launching products. To enable smooth circulation of lithium iron phosphate batteries across the domestic market, mandatory CCC certification is a high priority requirement for enterprises.
