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.

If a vacuum cleaner is to enter the South Korean market, the KC certification of the battery is an unavoidable threshold. This is a mandatory certification promoted by the Korea Institute of Standards and Technology (KATS), which focuses on the safety and electromagnetic compatibility of electronic and electrical products. As the battery of a vacuum cleaner is a portable lithium battery, it has been explicitly included in the scope of mandatory certification.

Why can the battery of a sweeper purchased online remain safe in complex environments when transported across regions? This is inseparable from UN38.3 certification. It originates from Article 38.3 of the United Nations Manual of Tests and Criteria for the Transport of Dangerous Goods and is a mandatory requirement for the air transportation of lithium batteries. After the 66th edition of the International Air Transport Association\'s (IATA) Dangerous Goods Regulations came into effect in 2025, restrictions were also imposed on the transportation capacity of lithium battery-containing equipment such as vacuum cleaners. This requirement will be officially enforced from 2026.
