亞馬遜物流庫存倉儲限制

注意： 自 2020 年 8 月 16 日起，倉儲限制額度的庫存績效指標分數閾值將從 400 調整為 500。

為更好地管理運營中心的倉儲空間，以便更快地接收商品并配送至買家，我們可能會實行庫存倉儲限制。倉儲限制額度基于體積（以立方英尺為單位）計算，且不同倉儲類型算法也不一樣。 您的當前和潛在倉儲限制和使用情況將顯示在“倉儲監視器”上，以便您在庫存績效控制面板和貨件處理進度中查看。

倉儲限制標準

【個人銷售賬戶】具有固定的倉儲限制額度，即 10 立方英尺，該值不會改變。個人銷售賬戶的倉儲限制額度不會提高。

【專業銷售賬戶】是否具有倉儲限制以及具體限制額度取決于以下標準：

• 對于庫存績效指標 (IPI) 分數在上述任一分數檢查周中保持在 500 或以上的賣家，其標準尺寸商品、大件商品以及服裝和鞋靴類商品就將獲得無限倉儲容量。（請參見下面倉儲限制時間表中的分數檢查時間安排。）

• 銷售時間不足 26 周的新賣家，或者在兩個分數檢查周都沒有足夠的銷售數據來生成庫存績效指標分數的賣家，將沒有倉儲限制。

對于標準尺寸、大件、服裝或鞋靴類商品，具有倉儲限制的專業賬戶仍將擁有至少 25 立方英尺的倉儲空間。

專業賬戶持有人可以在庫存績效控制面板中追蹤其庫存績效指標，并在庫存績效指標幫助頁面上了解庫存績效指標。該控制面板是您的亞馬遜物流業務優化中心，可以為您提供量身定制的建議來幫助您提高銷量和降低成本。您的庫存績效指標分數將根據您的日常情況每周更新一次。

我們使用多種因素計算倉儲限制額度，其中包括：

• 您的銷量（包括季節性銷量）

• 您的歷史庫存績效指標分數

• 可用的運營中心容量

對于持續擁有較高庫存績效指標分數的賣家，我們會根據銷量和可用容量進行調整，設置比較高的倉儲限制額度。設置下個季度的倉儲限制額度時，亞馬遜會考慮您近期的銷量和上一年的季節性銷量。

倉儲限制時間表

倉儲限制按體積設置。我們將根據您在兩個分數檢查周的庫存績效指標分數來確定您 2020 年剩余的倉儲限制：2020 年 7 月 12 日那周（29 周）和 2020 年 8 月 10 日那周（33 周）。只要您的分數在任一分數檢查周達到 500 或以上，您就將擁有無限量的倉儲空間。

倉儲類型

倉儲限制適用于六種倉儲類型：標準尺寸商品、大件商品、服裝、鞋靴、易燃物和氣溶膠。 您可以使用亞馬遜物流庫齡頁面和庫齡報告查看您的商品被歸為哪種倉儲類型及其占據多少立方英尺的空間。

如果您未在倉儲監視器中看到倉儲類型，則是因為您未對此倉儲類型實行限制。

危險品倉儲限制調整（易燃物和氣溶膠）與其他倉儲類型分開處理。有關更多詳情，請參閱亞馬遜物流危險品計劃。

注意： 亞馬遜根據商品特征確定您庫存的倉儲類型。倉儲類型不是賣家可以調整的分類。商品不按多種倉儲類型進行分類。

由立方英寸換算為立方英尺

1. 長 x 寬 x 高（以英寸為單位）得出體積。

2. 用體積數除以 1,728，即 12 立方英寸。
   

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

注意： 亞馬遜可能會使用代表性樣本驗證商品的重量和尺寸。如果亞馬遜的信息與賣家的信息存在差異，我們將使用亞馬遜關于商品重量和尺寸的信息來計算費用。亞馬遜可能會不時更改關于商品重量和尺寸的信息，以反映更新后的測量結果。根據商品的重量和尺寸計算費用，并在計算時使用亞馬遜關于商品重量和尺寸的信息。

超出您的亞馬遜物流倉儲限制額度

根據亞馬遜物流庫存倉儲限制政策，只有當您的庫存水平低于相應倉儲類型的倉儲限制額度時，您才能為該倉儲類型創建發往亞馬遜的新貨件。

例如，如果您的標準尺寸庫存的當前限制額度為 25 立方英尺，而您已在亞馬遜運營中心擁有 26 立方英尺的標準尺寸庫存，則您將無法創建新的標準尺寸商品貨件。 但是，如果您大件商品的庫存水平低于倉儲限制額度，則可以創建大件商品的貨件。

如果您發送的庫存超過倉儲限制額度所允許的數量，運營中心可能會拒收多余的庫存。有關更多信息，請參閱運輸和路線安排要求。

對于任何倉儲類型，如果您的現有庫存在給定月份中的任何一天超出限額，您將需要支付倉儲超量費。請訪問倉儲超量費幫助頁面了解更多信息。

減少庫存

您可以通過以下三種方式減少您存放在中心內的庫存量：

• 銷售更多庫存。管理冗余庫存提供了有關如何提高銷量的建議。

• 通過創建移除訂單，請求退回庫存。

• 通過創建移除訂單，請求棄置庫存。

有關更多信息，請參閱移除庫存（概覽）。

重要： 當您提交移除訂單或進行類似更改時，庫存倉儲監視器會在您的請求處理完畢后顯示此類更改，通常是在第二天顯示。另外，會計入您的整體庫存數量。

追蹤 ASIN 限制

我們可能還會針對特定 ASIN 創建倉儲限制。如果特定 ASIN 限制適用于您的賣家賬戶，您可以在可下載的【庫存狀況】報告中的 【ASIN 限制】標題下找到詳細信息。在線【庫存狀況】報告中不提供這些信息。請參閱亞馬遜物流 ASIN 數量限制 。

常見問題

我能否購買倉儲空間？

目前，亞馬遜的倉儲空間不提供購買途徑。

我能否更改商品的倉儲類型？

不能，倉儲類型是由亞馬遜根據商品特征確定的。

您可以在庫齡頁面上查看您的商品被歸為哪種倉儲類型及其占據多少立方英尺的空間。

我能否用一種倉儲類型的空間抵換另一種倉儲類型的空間？

不能，不同倉儲類型的庫存倉儲空間無法抵換。

危險品倉儲類型有何變化？

之前稱為“危險品”的倉儲類型已轉換為兩個新倉儲類型 – 氣溶膠和易燃物。調整后，氣溶膠和易燃物倉儲類型的倉儲限制額度有單獨的計算規則。有關更多詳情，請參閱亞馬遜物流危險品計劃。

如果我沒有庫存績效指標分數，或者我是新加入的亞馬遜物流賣家，會怎么樣？

大多數具有專業銷售賬戶的賣家都會有庫存績效指標分數，但有些賬戶沒有，原因可能是我們沒有充足的數據為這部分賬戶（例如新亞馬遜物流賣家或亞馬遜物流庫存量較小）生成分數。

在您首次獲得庫存績效指標分數后，在兩個完整的倉儲限制周期里，亞馬遜不會對您實行任何倉儲限制。

您可以點擊庫存績效指標分數顏色條下方的【顯示詳情】鏈接，查看您獲得第一個庫存績效指標分數的日期。這將顯示您的【歷史績效指標】，而您的第一個分數日期將在圖表上方顯示。

大多數賣家將在亞馬遜物流收到其首件商品之后的大約 15 周后獲得第一個庫存績效指標分數。

請訪問庫存績效控制面板，了解有關管理庫存的建議。

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

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.

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.
