迟发率
迟发率 (LSR) 是在 10 天或 30 天的时间段内，预计发货时间之后确认发货的订单数占订单总数的百分比。迟发率仅适用于卖家自配送订单。
在预计发货日期前确认订单发货十分重要，这样买家才能在线查看他们的已发货订单的状态。订单延迟确认发货可能会对买家体验产生负面影响，并导致索赔、负面反馈和/或买家联系次数增加。
注意： 预计发货日期会根据国家法定假日进行调整。
我们的政策规定，卖家应将迟发率维持在 4% 以下，这样才能在亚马逊商城销售商品。迟发率高于 4% 可能会导致账户停用。
要查看您的迟发率并下载迟发率报告，请执行以下操作：
前往账户状况页面。
在【配送绩效】部分，点击【查看详情】。
选择【迟发率】选项卡。 向下滚动并点击【下载报告】按钮。

Late Shipment Rate
The Late Shipment Rate (LSR) represents orders ship confirmed after the expected ship date as a percentage of total orders, over both a 10-day or a 30-day period. LSR only applies to seller-fulfilled orders.
It's important to confirm the shipment of orders by the expected ship date so that customers can see the status of their shipped orders online. Orders that are ship confirmed late may negatively impact customer experience and lead to increased claims, negative feedback and/or customer contacts.
Note: Expected ship dates are adjusted for national holidays.
Our policy is that sellers should maintain an LSR under 4% in order to sell on Amazon. An LSR above 4% may result in account deactivation.
To view your LSR and download your LSR report:
Go to the Account Health page.
In the Shipping Performance section, click View details.
Select the Late Shipment Rate tab. Scroll down and click the Download Report button.
