For manufacturers of automotive emergency start power supplies planning to enter the EU market, CE certification is an indispensable key step. The CE marking, as a mandatory safety symbol stipulated by EU law, directly affects whether a product can circulate freely in EU member states.

Button batteries have become common power supply components for various electronic consumer products due to their small size. However, manufacturers exporting to the United States must pay attention to a hard requirement - UL 4200A-2023 certification, which is a mandatory safety rule clearly defined by the U.S. Consumer Product Safety Commission (CPSC).

Button batteries are named for their resemblance to small buttons. Their diameters typically range from 4.8mm to 30mm, and their thicknesses are between 1.0mm and 7.7mm. As a battery category classified by shape, they are distinguished from cylindrical and prismatic batteries and are divided into rechargeable and non-rechargeable types. They are widely compatible with various small electronic devices. For producers of such products, CB certification is an important step to open up the global market.

If you want Bluetooth headphones to enter the Japanese market, TELEC certification is an unavoidable threshold. As a mandatory certification stipulated in Japan\'s Radio Law, it is similar to the domestic SRRC certification and is supervised by the Ministry of Internal Affairs and Communications (MIC). The GITEKI technical standard suitability certificate is issued by institutions such as TELEC. Uncertified products not only cannot be listed on platforms like Amazon, but may also face recalls and fines.

For enterprises planning to introduce Bluetooth headphones to the Japanese market, TELEC certification is not an \"option\" but a \"hard threshold\" that must be crossed. This requirement is not an industry practice but a clear stipulation of Japan\'s Radio Wave Law - all equipment with wireless transmission functions can only legally enter the Japanese market after passing the TELEC certification.

Many friends who are engaged in the export of pouch batteries or international logistics have encountered the situation where their goods were rejected - most likely because they haven\'t obtained the UN38.3 certification. In fact, this is not an additional requirement but a clear stipulation in the United Nations\' Recommendation on the Transport of Dangerous Goods: Due to their high energy density and thin casings, pouch batteries may pose risks of leakage and fire during transportation due to compression and temperature changes. They must pass the UN38.3 test to prove their safety in extreme environments. Otherwise, international logistics providers will not dare to accept them, and customs will also intercept them.

On August 15, 2025, the new version of the \"Compulsory Product Certification Implementation Rules\" was officially implemented, marking an important adjustment to the CCC certification for pouch batteries. As a core component of consumer electronics such as mobile phones and laptops, the safety certification of pouch batteries has become a hard threshold for market access.

For small desktop fans to enter the South Korean market, the KC certification of batteries is an unavoidable threshold. As a mandatory safety certification system in South Korea, KC certification is based on the Electrical Appliance Safety Management Act, ensuring that batteries comply with South Korean national standards in terms of safety, environmental protection, and electromagnetic compatibility. It can be regarded as the \"entry ticket\" for products to enter the market legally.
