KC certification is a mandatory certification system implemented in South Korea for electronic and electrical products, aimed at ensuring that products comply with South Korea\'s safety and electromagnetic compatibility standards. The Korean market has strict quality control over imported goods, and smart rings, as electronic products, must pass KC certification in order to be legally sold in the Korean market.
CE-RED certification is a mandatory compliance requirement of the European Union for wireless devices. For smartwatches with wireless functions such as Bluetooth and Wi Fi, its importance is mainly reflected in the following three aspects.
The Brazilian market has enormous potential, but in order to successfully enter, ANATEL certification is an essential first step. As an authoritative standard certified by the Brazilian Communications Authority, ANATEL certification is not only a guarantee of product quality, but also a legal entry threshold into the Brazilian market.
