Recently, the Civil Aviation Administration has implemented stringent regulations concerning "power banks," prohibiting passengers from carrying units without a valid 3C mark, those with unclear 3C marks, or recalled power banks on domestic flights, effective June 28. The 3C certification, also known as China Compulsory Certification, ensures product safety and quality. Following the enforcement of these new regulations, a concerning trend has emerged on e-commerce platforms: the sale of counterfeit 3C certification label stickers.
