亚马逊物流当日达

Amazon.com 提供其最快的配送体验，使得超过100,000 件符合配送要求的商品能够通过独特的运营中心网络在短达 5 个小时内配送给买家。库存绩效指标不低于 550 的所有卖家都有资格参与该计划。目前，亚马逊不对该项服务收取任何额外费用。当某个 ASIN 符合亚马逊物流当日达条件时，亚马逊会自动将该 ASIN 的库存移至该计划的配送和运营中心，并将最快的当日达配送选项应用于 Amazon.com 上最具竞争力的商品。请参阅以下内容，了解其他资格条件。

ASIN 资格

要符合该计划的要求，卖家的库存绩效指标分数不得低于 550，并且 ASIN 必须满足以下几个条件：

• 亚马逊配送（亚马逊物流）

• 状况为新品

• 轻小、不贵重

• 未分类为危险品

• SKU 无法注册加入轻小商品计划

• 库存数量达到或超出补充库存工具中显示的目标库存范围

资格条件可能会适时改变。如果 ASIN 满足更新后的条件，便将自动符合要求，此页面也将予以更新。

ASIN 选品

可选择符合所有资格要求的 ASIN 加入该计划。我们将根据需求选择符合要求的 ASIN。所选 ASIN 的总数受该计划的运营中心的可用容量限制。我们会定期审核和更新选定的 ASIN，以便根据季节性因素和不断变化的买家需求进行调整。

ASIN 库存

当某个 ASIN 选用亚马逊物流当日达配送方式时，与最具竞争力的商品相关联的部分库存将被移入该计划的配送和运营中心。此库存主要用于在该计划的覆盖区域内配送亚马逊物流当日达商品，但也可用于配送承诺延长配送时限的其他亚马逊物流商品。如果某个 ASIN 不再符合资格条件，或者对该 ASIN 的需求发生了变化，则可以将该 ASIN 从相关计划中移除，并将库存移至亚马逊配送网络中的其他运营中心。

FBA Same-Day Delivery

Amazon.com is offering its fastest delivery experience yet, making more than 100,000 products eligible for delivery to customers in as little as 5 hours from a unique network of fulfillment centers. All sellers with an Inventory Performance Index (IPI) of 550 or higher are eligible for the program, and there is currently no additional fee for the service. When an ASIN becomes eligible for FBA Same-Day Delivery, Amazon will automatically move inventory of that ASIN into distribution and fulfillment centers for the program and apply the fastest Same-Day ship option to the most competitive offer(s) on Amazon.com. See below for additional eligibility criteria.

ASIN eligibility

To be eligible for the program, the seller must have an IPI score of 550 or higher, and the ASIN must meet several criteria:

• Fulfilled by Amazon (FBA)

• New condition

• Not large, heavy, or expensive

• Not classified as a dangerous good

• SKU cannot be enrolled in the Small and Light program

• Inventory amount meets or exceeds the target inventory range shown in the Restock Inventory tool

Eligibility criteria may shift over time. ASINs will automatically become eligible if they meet the updated criteria and this page will be updated.

ASIN selection

An ASIN that meets all eligibility requirements may be selected for the program. Eligible ASINs are selected based on demand. The total number of ASINs selected is limited by available capacity in fulfillment centers for the program. Selected ASINs are reviewed and refreshed on a regular basis to adjust for seasonality and changing customer demand.

ASIN inventory

When an ASIN is selected for FBA Same-Day Delivery, some of the inventory associated with the most competitive offers will be moved into distribution and fulfillment centers for the program. This inventory will primarily be used to fulfill FBA Same-Day Delivery offers within the program's coverage area, but the inventory can also be used to fulfill other FBA offers with an extended delivery promise. If an ASIN no longer meets the eligibility criteria, or demand for the ASIN changes, the ASIN may be removed from the program and the inventory moved to other fulfillment centers in Amazon's network.
