美国果蔬产品等级规格工作是美国农业部农产品市场营销局(AMS)“果蔬项目”框架内开展的一项工作，由该项目下设的新鲜产品分部(FPB)和加工产品分部(PPB)具体负责。依托于完善的工作网络，FPB和PPB在果蔬等级规格标准化方面开展的工作主要包括：一是制定果蔬等级规格标准和分级手册；二是研究解决果蔬分等分级的技术问题；三是实施果蔬等级规格符合性认证；四是开展果蔬等级规格符合性检查。

美国果蔬等级规格标准的覆盖面较广，数量较多，内容十分丰富。目前，美国已经制定了148项新鲜果蔬标准，其中鲜食蔬菜标准62项、鲜食水果标准31项、坚果标准16项、用于加工的新鲜蔬菜标准24项、用于加工的新鲜水果标准15项；同时，制定了147项加工果蔬标准，其中水果干制品标准14项、冷冻水果标准29项、罐装水果制品标准35项、冷冻蔬菜标准28项、罐装蔬菜制品标准37项、其他果蔬制品标准4项。除果蔬等级规格标准外，AMS还制定了包括分级手册在内的多个指导性文件，供检查员执行果蔬产品检查使用。

虽然美国果蔬等级规格标准是自愿性的，但却成为促进果蔬产品销售的重要工具，在果蔬生产、加工、流通和贸易中得到广泛应用。AMS力确保这些标准在全国范围内统一协调应用，指定专门机构负责对果蔬产品实施等级规格认证和检查，并制定了新鲜果蔬产品检查证明。

目前，美国已经制定了148项新鲜果蔬标准，其中鲜食蔬菜标准62项、鲜食水果标准31项、坚果标准16项、用于加工的新鲜蔬菜标准24项、用于加工的新鲜水果标准15项；同时，制定了147项加工果蔬标准，其中水果干制品标准14项、冷冻水果标准29项、罐装水果制品标准35项、冷冻蔬菜标准28项、罐装蔬菜制品标准37项、其他果蔬制品标准4项。具体的标准如下：
