库存仓储超量费

如果您的现有库存在特定月份超出了仓储限制，那么除了月度库存仓储费和长期仓储费（如适用）之外，您还需要支付【库存仓储超量费】。仓储超量费取决于超出仓储限制额度的天数。即使后来您的库存水平降回到当月分配的仓储限制额度之内，也仍然需要支付该费用。仓储超量费将按照每立方英尺 $10 的标准每月收取一次，并基于您的库存在中心占用的超出仓储限制额度的所有空间的日平均体积（以立方英尺为单位）计算。有关更多信息，请访问亚马逊物流库存仓储限制。

体积基于已根据和要求妥善包装且准备配送的商品的尺寸测量得出。亚马逊保留测量或称重已包装商品或代表性样本的权利，以及确定仓储类型的权利。如与卖家提供的信息有冲突，将以亚马逊的测量结果为准。

时间表和示例

以下示例说明了此费用的评估和收取方式：

确定仓储限制状态

您可以随时查看库存绩效控制面板或货件处理进度中的“仓储监视器”，来判断自己是否超出限制。如果超出限制，您将看到一个提醒图标。如果您超出限制，您可以用当前使用值减去当前限制值，来计算该仓储类型的当前超量值。如果您超出了每种仓储类型的限制，并且您将产生库存仓储超量费，我们还会每周向您发送提醒。

库存仓储超量费报告

库存仓储超量费报告按仓储类型和日期提供您在中心内超出仓储限制额度的库存的预计库存仓储超量费。此报告在月末生成，从次月第二天开始可供下载。您可以在【报告】菜单中选择【配送】，然后在结果页面的左侧选择【付款】下的库存仓储超量费。

计算月度库存仓储超量费估算值

我们会使用以下公式按仓储类型提供月度库存仓储超量费估算值：

预计的月度超量费 =（当前超量值 x 每日超量费率 x 月剩余收费天数) + 截至目前产生的月度超量费

当前超量值 = 当前使用量 - 当前限制量

每日超量费率 = $10/当月天数

月剩余收费天数 = 当前月份天数 - 当日日期数值 + 1

示例：

标准尺寸商品仓储限制值 = 100 立方英尺

库存 = 110 立方英尺

今天 = 7 月 12 日

当月收费天数 = 31 - 12+1 = 20

每日超量费率 = $10/31 = $0.322581

当前超量值 = 10 立方英尺

截至目前产生的月度超量费 = $50（第 1-11 天已经产生的超量费）

预计的月度超量费 = (10 * $0.322581 x 20) + $50 = $114.5162

重要： 当您的库存在本月产生超量费时，此估算值适用于所有仓储类型。这是假定未针对当前超出仓储限制的库存采取任何措施的情况下预计的月度超量费。预计值应仅用于参考目的。应付费用将在每月结束后确定。

根据英寸计算立方英尺

1. 长 x 宽 x 高（以英寸为单位）得出体积。

2. 用体积数除以 1,728，得出 12 立方英寸。

示例：将 47 英寸 x 12 英寸 x 10 英寸所得的值除以 1,728 = 3.3 立方英尺。

常见问题

如何知道我是否需要支付库存仓储超量费？

如果您拥有专业销售账户，那么您在给定月份任意一天结束时超出了给定仓储类型的当前限制额度，则需支付仓储超量费。即使后来您的库存水平降回到当月分配的仓储限制额度之内，也仍然需要支付该费用。

我如何确定当前有哪些 SKU 占用了特定仓储类型的仓储空间？

当前使用量是从现有库存中减去所有待移除库存得出的实时数据。亚马逊物流库龄页面提供了所有在售的亚马逊物流商品列表，其中标注了商品的仓储类型（标准尺寸、大件、服装、鞋靴、易燃物或气溶胶），以及 ASIN 占用的空间体积（在售商品数量 x 每件商品的体积 = 立方米）。您也可通过库龄报告获取此信息。

虽然使用库龄数据估算当前使用量是一种好方法，但是估算值可能因为多种原因与仓储监视器上显示的当前使用量值不同。

1. 当前使用量值是实时的数据源，而库龄报告数据可能因数据处理时间而延迟最多 72 小时。

2. 当前使用量值包含不可售库存，但不包含任何待移除商品，而库龄数据和相关报告中不包含这些值。

3. 没有在售商品的库存可能会计入当前使用量（例如无在售信息的）。

亚马逊何时向我收取库存仓储超量费？

如果某个月份产生了库存仓储超量费，亚马逊将在该月结束后收取这笔费用。例如，假设您在 7 月 1 日超出了仓储限制额度，并在 7 月 5 日之前移除部分库存，使库存水平降回到仓储限制额度之内。在 8 月 1 日，您将需要为超出 7 月份限制量的 4 天缴纳超量费。

库存仓储超量费是否适用于易燃物质和气溶胶？

否，如果您超出了易燃物质或气溶胶仓储限制，不需要支付超量费。超量费仅适用于标准尺寸、超大尺寸、服装和鞋类仓储类型。

FBA inventory storage overage fees

If your existing inventory exceeds your storage limits for a given month, you will be charged an inventory storage overage fee in addition to monthly inventory storage fees and, if applicable, long-term storage fees. The overage fee is based on how many days your storage limits are exceeded. This charge will occur even if your inventory is subsequently reduced to a level below your storage limits allocated for that month. It will be charged monthly at $10 per cubic foot based on the daily average volume (measured in cubic feet) for any space your inventory occupies in Amazon fulfillment centers beyond your storage limits. For more information, visit FBA inventory storage limits.

The volume measurement is based on unit size when properly packaged and ready to ship in accordance with  policies and requirements. Amazon reserves the right to measure or weigh packaged units or representative samples and to determine the storage type. In the event of any conflict between an Amazon measurement and information provided by the seller, Amazon's measurement will govern.

Timeline and example

The following example illustrates how this fee is assessed and charged:

Event with sample date	Sample values
Inventory storage overage fee accrues on July 1
The seller’s inventory exceeds their standard-size storage limit by 100 cubic feet, so they will incur an overage fee of $10 per cubic foot, or $1,000 total, if no action is taken (to be assessed and charged in August).	Standard-size storage limit	1,000 cubic feet
Space taken by existing standard-size inventory	1,100 cubic feet
Current standard-size overage	100 cubic feet
Potential storage overage fee	$1,000
Seller reduces inventory exceeding limit on July 5
The seller creates a removal order for 80 cubic feet of standard-size inventory on July 5. No other standard-size inventory is sold or removed during July.	Standard-size overage, July 1 – 4	100 cubic feet
Standard-size removal, July 5	80 cubic feet
Standard-size overage, July 5 – 31	20 cubic feet
Inventory storage overage fee billed in August
The July seller’s average overage was 30.322 cubic feet. They will be charged $10 per cubic foot for a July total of $303.22.	July average standard-size overage	30.322
Storage overage fee per cubic foot	$10
Total July storage overage fee	$303.22

Determining storage limit status

You can check if you are over your limit at any time by viewing the Storage Monitor on the Inventory Performance dashboard or in the Shipping Queue. You will see an alert icon if you are over your limit. If you are over your limit, you can calculate your current overage for that storage type by subtracting your current usage from your current storage limit. We will also send you weekly alerts if you are over your limit for each storage type and you will incur inventory storage overage fees.

Inventory storage overage fees report

The Inventory storage overage fees report provides the inventory storage overage fees for each storage type and day your inventory in Amazon fulfillment centers exceeded your storage limits. This month-end report is available for download starting the second day of the following month. It is available from the Reports menu by selecting Fulfillment and on the resulting page selecting Inventory storage overage fees under Payments on the left.

Calculating the monthly inventory storage overage fee estimate

We provide an estimate of your monthly inventory storage overage fee by storage type using the following formula:

Estimated monthly overage fee = (current overage x daily overage rate x charge days remaining in month) + monthly overage fees incurred to date

Current overage = current usage – current limit

Daily overage rate = $10 / number of days in current month

Charge Days Remaining in Month = number of days in current month – current day number + 1

Example:

Standard-size storage limit = 100 cubic feet

Inventory = 110 cubic feet

Today = July 12

Charge days in current month = 31 – 12 + 1 = 20

Daily overage rate = $10 / 31 = $0.322581

Current overage = 10 cubic feet

Monthly overage fees incurred to date = $50 (calculated from overage already incurred in days 1-11)

Estimated monthly overage fee = (10 * $0.322581 x 20) + $50 = $114.5162

Important: This estimate applies to any storage type when your inventory has incurred overage fees in the current month. It is a monthly estimate and assumes that no action has been taken on any inventory that currently exceeds your storage limits. The estimate should be used for reference only. Charges are not finalized until after the end of each month.

Calculating cubic feet from inches

1. Multiply length x width x height in inches to get the volume.

2. 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.

Frequently asked questions

How do I know if I am subject to the inventory storage overage fee?

If you have a Professional selling account, you are subject to the overage fee if you have exceeded your current limits for a given storage type by the end of the day for any day in a given month. This charge will occur even if your inventory was subsequently reduced to a level below your storage limits allocated for that month.

How can I determine which SKUs are contributing to my current usage for a storage type?

Current usage is a real-time representation of your on-hand inventory minus any pending removals. FBA Inventory Age provides a list of all of your active FBA listings, along with their storage type (standard-size, oversize, apparel, footwear, flammable, or aerosol) and how much volume the ASIN is taking up (Available units x volume per unit = cubic feet). This information is also available via the Inventory Age report.

While the Inventory Age data is good way to approximate current usage, it may not match your current usage value displayed on the Storage Monitor for a few reasons.

1. Current usage is a real-time data source, and the Inventory Age report data may be delayed up to 72 hours due to data processing times.

2. Current usage includes unsellable inventory and excludes any units pending removal, and these values are not included on the Inventory Age and the associated report.

3. Inventory that does not have an active listing may be counted in current usage (such as stranded inventory).

When will I be charged inventory storage overage fees?

You will be charged applicable inventory storage overage fees after the end of the month in which the fees were incurred. For example, let’s say that you exceeded your storage limit on July 1 and removed inventory to a level below your limit by July 5. On August 1, you would be charged for the four days you were over the limit in July.

Do inventory storage overage fees apply to flammable and aerosol storage?

No, overage fees are not charged if you exceed your flammable or aerosol storage. Overage fees apply only to standard-size, oversize, apparel, and footwear storage types.
