Certified Agricultural Standards (CAS)

CAS is a certification registered by the Ministry of Agriculture, Executive Yuan with the Intellectual Property Office, Ministry of Economic Affairs. 

It promotes domestically produced high-quality and safe agricultural produce and their processed products, enhances the added value of products, and protects the rights and interests of producers and consumers and was introduced by the Ministry of Agriculture in 1978. Only certified products can use the CAS label. Since the certification system was introduced, it has become widely recognized and trusted in Taiwan and is synonymous with high-quality and safe produce, while also being differentiating produce from imported agricultural produce.

At present, there are two categories of CAS; "CA " and "CAS Organic." Although both use design patterns, their meaning is different (compare the table below). All CAS labeled products have been checked by verification institutions and quality is guaranteed. When purchasing agricultural produce, pay more attention to purchasing.
