This paper delves into the practical application of CE certification and international standards such as ISO 9001 and ISO 14001 in laying hen cages. It focuses on how electrical safety and mechanical protection ensure access to high - end markets like the EU. Through technical requirements and the compliance advantages brought by certification, it reveals the risks and challenges faced by uncertified equipment during the export process. Supported by scientific data and industry cases, it provides authoritative guidance for farmers and procurement decision - makers in equipment selection, facilitating the establishment of an efficient and sustainable standardized laying hen farming system.
