亚马逊物流库存仓储限制
注意： 自 2020 年 8 月 16 日起，仓储限制额度的库存绩效指标分数阈值将从 400 调整为 500。
为更好地管理运营中心的仓储空间，以便更快地接收商品并配送至买家，我们可能会实行库存仓储限制。仓储限制额度基于体积（以立方英尺为单位）计算，且不同仓储类型算法也不一样。 您的当前和潜在仓储限制和使用情况将显示在“仓储监视器”上，以便您在库存绩效控制面板和货件处理进度中查看。
仓储限制标准
【个人销售账户】具有固定的仓储限制额度，即 10 立方英尺，该值不会改变。个人销售账户的仓储限制额度不会提高。
【专业销售账户】是否具有仓储限制以及具体限制额度取决于以下标准：
对于库存绩效指标 (IPI) 分数在上述任一分数检查周中保持在 500 或以上的卖家，其标准尺寸商品、大件商品以及服装和鞋靴类商品就将获得无限仓储容量。（请参见下面仓储限制时间表中的分数检查时间安排。）
销售时间不足 26 周的新卖家，或者在两个分数检查周都没有足够的销售数据来生成库存绩效指标分数的卖家，将没有仓储限制。
对于标准尺寸、大件、服装或鞋靴类商品，具有仓储限制的专业账户仍将拥有至少 25 立方英尺的仓储空间。
专业账户持有人可以在库存绩效控制面板中追踪其库存绩效指标，并在库存绩效指标帮助页面上了解库存绩效指标。该控制面板是您的亚马逊物流业务优化中心，可以为您提供量身定制的建议来帮助您提高销量和降低成本。您的库存绩效指标分数将根据您的日常库存管理情况每周更新一次。
我们使用多种因素计算仓储限制额度，其中包括：
您的销量（包括季节性销量）
您的历史库存绩效指标分数
可用的运营中心容量
对于持续拥有较高库存绩效指标分数的卖家，我们会根据销量和可用容量进行调整，设置比较高的仓储限制额度。设置下个季度的仓储限制额度时，亚马逊会考虑您近期的销量和上一年的季节性销量。
仓储限制时间表
仓储限制按体积设置。我们将根据您在两个分数检查周的库存绩效指标分数来确定您 2020 年剩余的仓储限制：2020 年 7 月 12 日那周（29 周）和 2020 年 8 月 10 日那周（33 周）。只要您的库存绩效指标分数在任一分数检查周达到 500 或以上，您就将拥有无限量的仓储空间。
仓储类型
仓储限制适用于六种仓储类型：标准尺寸商品、大件商品、服装、鞋靴、易燃物和气溶胶。 您可以使用亚马逊物流库龄页面和库龄报告查看您的商品被归为哪种仓储类型及其占据多少立方英尺的空间。
如果您未在仓储监视器中看到仓储类型，则是因为您未对此仓储类型实行限制。
危险品仓储限制调整（易燃物和气溶胶）与其他仓储类型分开处理。有关更多详情，请参阅亚马逊物流危险品计划。
注意： 亚马逊根据商品特征确定您库存的仓储类型。仓储类型不是卖家可以调整的分类。商品不按多种仓储类型进行分类。
由立方英寸换算为立方英尺
长 x 宽 x 高（以英寸为单位）得出体积。
用体积数除以 1,728，即 12 立方英寸。
示例： 将 47 x 12 x 10 英寸所得的值除以 1,728 = 3.3 立方英尺。
注意： 亚马逊可能会使用代表性样本验证商品的重量和尺寸。如果亚马逊的信息与卖家的信息存在差异，我们将使用亚马逊关于商品重量和尺寸的信息来计算费用。亚马逊可能会不时更改关于商品重量和尺寸的信息，以反映更新后的测量结果。根据商品的重量和尺寸计算费用，并在计算时使用亚马逊关于商品重量和尺寸的信息。
超出您的亚马逊物流仓储限制额度
根据亚马逊物流库存仓储限制政策，只有当您的库存水平低于相应仓储类型的仓储限制额度时，您才能为该仓储类型创建发往亚马逊的新货件。
例如，如果您的标准尺寸库存的当前限制额度为 25 立方英尺，而您已在亚马逊运营中心拥有 26 立方英尺的标准尺寸库存，则您将无法创建新的标准尺寸商品货件。 但是，如果您大件商品的库存水平低于仓储限制额度，则可以创建大件商品的货件。
如果您发送的库存超过仓储限制额度所允许的数量，运营中心可能会拒收多余的库存。有关更多信息，请参阅运输和路线安排要求。
对于任何仓储类型，如果您的现有库存在给定月份中的任何一天超出限额，您将需要支付仓储超量费。请访问仓储超量费帮助页面了解更多信息。
减少库存
您可以通过以下三种方式减少您存放在亚马逊运营中心内的库存量：
销售更多库存。管理冗余库存提供了有关如何提高销量的建议。
通过创建移除订单，请求退回库存。
通过创建移除订单，请求弃置库存。
有关更多信息，请参阅移除库存（概览）。
重要： 当您提交移除订单或进行类似更改时，库存仓储监视器会在您的请求处理完毕后显示此类更改，通常是在第二天显示。另外，买家退货会计入您的整体库存数量。
追踪 ASIN 限制
我们可能还会针对特定 ASIN 创建仓储限制。如果特定 ASIN 限制适用于您的卖家账户，您可以在可下载的【库存状况】报告中的 【ASIN 限制】标题下找到详细信息。在线【库存状况】报告中不提供这些信息。请参阅亚马逊物流 ASIN 数量限制 。
常见问题
我能否购买仓储空间？
目前，亚马逊的仓储空间不提供购买途径。
我能否更改商品的仓储类型？
不能，仓储类型是由亚马逊根据商品特征确定的。
您可以在亚马逊物流库龄页面上查看您的商品被归为哪种仓储类型及其占据多少立方英尺的空间。
我能否用一种仓储类型的空间抵换另一种仓储类型的空间？
不能，不同仓储类型的库存仓储空间无法抵换。
危险品仓储类型有何变化？
之前称为“危险品”的仓储类型已转换为两个新仓储类型 – 气溶胶和易燃物。调整后，气溶胶和易燃物仓储类型的仓储限制额度有单独的计算规则。有关更多详情，请参阅亚马逊物流危险品计划。
如果我没有库存绩效指标分数，或者我是新加入的亚马逊物流卖家，会怎么样？
大多数具有专业销售账户的卖家都会有库存绩效指标分数，但有些账户没有，原因可能是我们没有充足的数据为这部分账户（例如新亚马逊物流卖家或亚马逊物流库存量较小）生成分数。
在您首次获得库存绩效指标分数后，在两个完整的仓储限制周期里，亚马逊不会对您实行任何仓储限制。
您可以点击库存绩效指标分数颜色条下方的【显示详情】链接，查看您获得第一个库存绩效指标分数的日期。这将显示您的【历史绩效指标】，而您的第一个库存绩效指标分数日期将在图表上方显示。
大多数卖家将在亚马逊物流收到其首件商品之后的大约 15 周后获得第一个库存绩效指标分数。
请访问库存绩效控制面板，了解有关管理库存的建议。

FBA inventory storage limits
Note: Effective August 16, 2020, the IPI threshold for storage limits is 500 (previously 400).
To better manage fulfillment center storage space, so that products are received and delivered to buyers more quickly, inventory storage limits can be applied. Storage limits are based on volume (measured in cubic feet) and are set for each storage type. Your current and potential storage limits and usage are shown on the Storage Monitor display, which you can view in your Inventory performance dashboard and Shipping Queue.
Storage limits criteria
Individual selling accounts have a set storage limit of 10 cubic feet; this value does not change. Individual selling accounts are not subject to storage limit increases.
Professional selling accounts may or may not have storage limits, depending on the following criteria:
Sellers who maintain an Inventory Performance Index (IPI) of 500 or above on either of two score checkpoints will not be subject to storage volume limits for standard-size, oversize, apparel, and footwear items. (See the checkpoints in the storage limits schedule below.)
New sellers that have been active for less than 26 weeks, or sellers without enough sales data to generate an IPI score during both of the two score check weeks will not receive storage limits.
Professional accounts that do have storage limits will still have a minimum of 25 cubic feet for standard, over-size, apparel, or footwear sort types.
Professional account holders can track your Inventory Performance Index in the Inventory Performance Dashboard and learn about IPI on the IPI Help page. The dashboard provides a hub for optimizing your FBA business, including customized recommendations to grow your sales and reduce costs. Your IPI score is updated weekly based on your ongoing inventory management.
Storage limits are calculated using several factors including:
Your sales volume (including your sales' seasonality periods)
Your historical IPI scores
Available fulfillment center capacity
Sellers with consistently higher IPI scores will receive higher storage limits, adjusted for sales volume and available capacity. When setting limits for an upcoming quarter, Amazon considers both your recent sales volume and seasonal volume from the last year.
Storage limits schedule
Storage limits are set by volume. Your remaining 2020 storage limits will be determined based on your IPI during two score check weeks: the week of July 12, 2020 (Week 29) and the week of August 10, 2020 (Week 33). You are not subject to storage volume limits if your Inventory Performance Index is 500 or above on either one of these score check weeks.
Storage types
Storage limits are applicable for six storage types: standard-size, oversize, apparel, footwear, flammable, and aerosol. You can see which storage types your products are categorized as and how much cubic feet they occupy using the FBA Inventory Age page and the Inventory Age report.
If you do not see a storage type in your Storage Monitor, it is because you have a limit of zero for that storage type.
Dangerous goods storage limit adjustments (flammable and aerosol) are handled separately from other storage types. See FBA dangerous goods (hazmat) program for more details.
Note: Amazon determines the storage type of your inventory based on the characteristics of the product. Storage type is not a category that can sellers can adjust. Products are not classified by more than one storage type.
Calculating cubic feet from inches
Multiply length x width x height in inches to get the volume.
Divide the volume by 1,728, which is 12 cubic inches.
Example: A unit measuring 47 x 12 x 10 inches divided by 1,728 = 3.3 cubic feet.
Note: Amazon may verify the weight and dimensions of a product using representative samples. Amazon’s information about a product’s weight and dimensions will be used to calculate fees if there is a difference between Amazon’s information and a seller’s information. Amazon may change its information about a product’s weight and dimensions from time to time to reflect updated measurements. Fees based on the weight and dimensions of a product are calculated using Amazon’s information about the weight and dimensions of that product at the time the fee is calculated.
Exceeding your FBA storage limit
Under the FBA inventory storage limits policy, you will not be able to create a new shipment to Amazon for a storage type until your inventory level drops below your limit for that storage type.
For example, if your current limit for standard-size inventory is 25 cubic feet and you have 26 cubic feet of standard-size inventory at an Amazon fulfillment center, you will not be able to create a new standard-size inventory shipment. However, if you are below your storage limit for oversize inventory, you will be able to create shipments of oversize inventory.
If you send more inventory than your storage limit allows, the extra inventory may be refused at the fulfillment center. For more information, see Shipping and routing requirements.
Storage overage fees will be charged if your existing inventory exceeds your storage limit for any sort type on any day within a given month. Please visit the Overage fee help page to learn more.
Important: Storage overage fees will be charged if your existing inventory exceeds your storage limit for any sort type on any day within a given month. Please visit the Overage fee help page to learn more
Reducing inventory
There are three ways to decrease the amount of inventory you have in an Amazon fulfillment center:
Sell more inventory. Manage Excess Inventory provides recommendations to increase sales.
Request to have inventory returned to you by creating a removal order.
Request to have inventory disposed of by creating a removal order.
For more information, see Remove inventory (overview).
Important: When you submit a removal order or make similar changes, the inventory Storage Monitor won't reflect the changes until your request has been processed, typically on the following day. Also, customer returns contribute to your overall inventory count.
Tracking ASIN limits
We may also create storage limits for specific ASINs. If an ASIN-specific limit is applied to your seller account, you can find the details in the downloadable Inventory Health report under the header asin-limit. This information is not available in the online Inventory Health report. See ASIN quantity limits for FBA.
Frequently asked questions
Can I purchase storage space?
At this time, Amazon does not offer the ability to purchase storage space.
Can I change the storage type of a product?
No. Storage types are determined by Amazon based on characteristics of a product.
You can check which storage type your products are categorized as and how much cubic feet they occupy on the FBA Inventory age page.
Can I trade space for one storage type with space in another storage type?
No. Inventory cannot be traded between storage types.
What happened to the hazmat storage type?
The storage type previously referred to as “hazmat” has been converted into two new storage types – aerosol and flammable. Storage limit adjustments for aerosol and flammable storage types are handled separately. See FBA dangerous goods (hazmat) program for more details.
What if I do not have an IPI score or am a new FBA seller?
Most sellers with Professional selling accounts have an IPI score, but some do not because we do not have enough data to generate a score for the account (for example, sellers who are new to FBA or have small quantities of FBA inventory).
After you first receive an IPI score, you will not be subject to storage limits for two full storage limit cycles.
You can view the date you received your first IPI score by clicking the Show details link under the IPI score color bar. This will reveal your Historical performance index and your First IPI score date will be visible above the graph.
Most sellers will receive their first IPI score approximately 15 weeks after their first product is received by FBA.
