根據歐洲2092/91規定(歐洲經濟共同體,EEC),美國國家有機物管理辦法(NOP)，日本農業標準（JAS） 和CERES標準解釋
1. Group certification:
● Is a necessary tool to allow smallholders access to organic markets
● Requests a high level of commitment and knowledge by the organisation or certificate holder
● Is possible for crop production, animal husbandry, or beekeeping.
1．團體認證
● 團體認證是使小農戶得以進入有機產品市場的重要手段。
● 每個組織或通過認證標準的組織都必須熟悉團體認證的相關知識而且履行團體認證規定的責任。
● 作物生產、家畜飼養、或養蜂（業）可以通過團體認證

2. Normative framework:
● According to NOP, farmers with less than 5,000 USD annual turnovers can sell organic products without certification; this, however, refers more to smallholders in the USA, who sell directly to consumers. These producers are not allowed to display the USDA-seal.
● In 2003, the EU commission issued a "guidance" for group certification according to (EEC) 2092/91; this document, however, is not legally binding, and different EU member countries may have different positions on this; the paper limits group certification to developing countries as defined by the OECD (http://www.oecd.org/pdf/M00038000/M00038051.pdf).
