在卖家自配送 Prime 计划中保持注册状态
成功通过 Prime 试用期后，您将自动加入卖家自配送 Prime 计划。
在加入卖家自配送 Prime 计划后，要保持该状态，您必须要一直满足以下标准：
从“购买配送服务”购买配送服务： 您需要通过“购买配送服务”购买至少 99% 的货件标签，可以从“管理订单”页面上的“购买配送”工具或卖家自配送 API 进行购买。
承运人取件时间： 使用至少一家已获批准的“购买配送服务”承运人：UPS、USPS、TForce 或 FedEx。
对于“标准配送”或“隔日达”订单，承运人必须在当地时间下午 4:00 或之后到卖家处取件。
此外，卖家必须达到或超过以下绩效：
Prime 订单的准时发货率至少要达到 99%
至少 99% 的 Prime 订单使用“购买配送服务”
Prime 订单的取消率不得超过 0.5%
对于通过“购买配送服务”以外的其他渠道购买配送的 Prime 订单，准时送达率至少要达到 97%
如果您的绩效指标低于要求的水平，那么您将会失去加入卖家自配送 Prime 计划的资格，但是可以继续在亚马逊上销售这些商品，但不得带有 Prime 标记。如果卖家的指标有所提高，则有资格重新申请加入卖家自配送 Prime 计划。有关失去卖家自配送 Prime 计划的参与资格以及如何重新加入该计划的更多信息，请参阅卖家自配送 Prime 注册撤销页面。
