Optimization recommendations
What Amazon did: regional operations services
In the US, Amazon is implementing regional operations by dividing its fulfillment centers and delivery network into smaller, easier-to-serve regions, making more efficient use of inventory within each region. Shipping from regional operation centers to distribution stations helps reduce the time packages spend at distribution stations, reduces reliance on air freight, and enables products to be delivered to customers more quickly.
How sellers can optimize inbound shipping
● Create an inbound plan as recommended by Amazon, and deliver the products as planned
● To maximize the available inbound options, such as Amazon Managed Placement shipment splits (with no inbound placement fee), you can try the following:
1. Create separate shipments for standard-size products, non-sortable products, and products in each special handling category
2. Increase the number of boxes
3. For products packed in mixed boxes, ensure that all boxes have the same combination and quantity of products
● Provide an accurate estimated delivery window
How sellers can reduce costs and improve efficiency
Inbound Placement Service Fee
Amazon assesses and predicts customer demand for your products in different regions and recommends inbound placement options that will reduce your Inbound Placement Service fees
Inbound defect fee
Prevent shipments from being delivered to the wrong location
● Before shipping, carefully check whether the shipping label matches the fulfillment center and address in the system to avoid delivery to the wrong address due to mislabeling
● If you use a third-party logistics company, be sure to confirm with them and track the fulfillment center the shipment is expected to be sent to
How to avoid deleted and discarded shipments
● Try to include products with similar ship dates and transit times in the same shipment plan, and avoid sending shipments in the same shipment plan by both air and sea
● Ship as soon as possible after creating a shipment. If you are temporarily unable to ship or want to change an approved shipment plan, you must delete all shipments in that plan before any shipment in that plan arrives.
● If you use a third-party logistics company, please promptly enter an accurate delivery time window for the shipment to arrive at the fulfillment center when you create the shipment, and update it at any time based on the actual situation before the time window begins

Optimization suggestions
What Amazon did: intelligently forecast regional demand and allocate products
Amazon uses machine learning algorithms to better predict which products customers in different regions want and when they want to buy them, ensure inventory is available where needed, improve the match between products and regional fulfillment centers, place products closer to customers, and increase the ability to complete orders in one shipment from the location closest to the customer.
How can sellers keep their inventory healthy
Keep bestselling products in stock
● Create a shipment plan as recommended by Amazon, and send the products according to the plan
Reduce the cost of slow-moving inventory
● Monitor your storage capacity and act quickly to increase capacity and reduce excess
● Increase capacity: apply for additional storage capacity
● Cost cutting: Clear excess inventory
How can sellers reduce costs and increase efficiency
low inventory cost coverage fee
Amazon calculates your historical days of supply based on product sales. Keeping your historical days of supply at the required level can help you avoid being charged the low inventory cost coverage fee.
Overage fee
Sellers should monitor storage capacity and, when storage utilization exceeds 80%, promptly remove slow-moving inventory or request additional storage capacity to avoid overage fees.
Aging inventory surcharge
Sellers should monitor the age of their inventory in stock and promptly remove slow-moving inventory when it becomes too old to avoid aging inventory surcharges.
Storage Utilization Surcharge
Sellers should pay attention to how their in-stock inventory uses storage capacity and promptly remove slow-selling inventory that takes up more storage capacity to avoid the storage utilization surcharge.

Frequently Asked Questions

first-mile inbounding
Will FBA Fulfillment fees be reduced after the new inbound placement service fee is introduced?
To use the Amazon network more efficiently, Amazon charges separately for inbound and outbound activities and provides you with more flexible Inbound Placement Service options. Starting April 15, 2024, Amazon will lower Fulfillment by Amazon fulfillment fees by an average of $0.20 per item for sortable products and by an average of $0.61 per item for large bulky products. Starting on the same day (that is, 45 days after receipt of the shipment), Amazon will also begin charging for the Inbound Placement Service for the first time. You can choose from different inbound placement options, and depending on how you send products to us, you can reduce or completely avoid these inbound fees.
Pro Tips:
You can use the FBA Revenue Calculator to estimate fees for a single SKU or multiple SKUs. The new Inbound Placement Service fee and reduced FBA fulfillment fees were updated in the calculator on 3/15.
Do oversized products incur the Fulfillment by Amazon inbound placement service fee?
The FBA inbound placement service fee does not apply to oversized products. For more information, go to size bands.
Why do I only see one or two Inbound Placement Service options when creating certain shipment plans?How can I maximize the number of available inbound options?
A number of factors are taken into account when providing inbound configuration options, and the system will only display the corresponding inbound configuration options if the seller's shipment meets the requirements.
Factors that affect the number of inbound placement options include:
- Whether the shipment includes standard-size, non-sortable, or special-handling-category products
- Whether each box contains the same SKU mix and quantities
- Quantity per item and number of boxes
- The seller’s current inventory levels in FBA and where buyer demand is located.
Tips:
To maximize the number of inbound placement options, try the following:
• Create separate shipments for standard-sized products, non-standard-sized products, and products in each special handling category
• Make sure the combination and quantity of products are the same in all boxes
• Increase the number of boxes
Please note that the “ship-from address” entered when you create a shipment does not affect the inbound placement options or the assigned warehouses. We recommend using the actual ship-from address to access more logistics solutions (for example, only when you use a ship-from address in China can you choose the SEND Amazon Partnered Carrier program)
What happens if I create a shipment plan that includes standard-size items, non-standard-size items, or special-handling category items at the same time?
This may reduce the available inbound placement options. In addition, seller inventory may be sent to multiple inbound locations, even if the seller selects the minimum shipment splits placement option (for example, a receiving center for sortable products and a receiving center for non-sortable products). In this case, even if shipments are sent to multiple locations, the minimum shipment split rate will still apply to each shipment in the shipment plan.
Pro Tips:
We recommend that sellers create separate shipment plans for sortable products, non-sortable products, and products in each of the following categories:
• Apparel
• Jewelry
• Footwear
• Watches
• dangerous goods (hazmat)
What happens if I don’t send my inventory to the Amazon fulfillment center specified in the inbound plan, or if I send an incomplete shipment (remove or abandon part of the shipment)?
Amazon will charge the seller the Fulfillment by Amazon inbound placement service fee 45 days after receiving the shipment, based on the actual inbound location and quantity received. If the shipment is sent to a location different from the inbound plan (a misrouted shipment), or does not arrive at the Amazon fulfillment center within the time frame specified in the inbound policy (a deleted or abandoned shipment), Amazon will charge a Fulfillment by Amazon inbound service fee based on the shipment actually received and the inbound location, and this fee may be higher than the estimated fee at the time the shipment was created.
Quick tip:
1. After you create a shipment, ship it to the fulfillment centers assigned in the shipment plan and in the specified product quantities
2. Create products with similar ship dates and transit times in the same shipment plan
3. Ship as soon as possible after creating a shipment. If for any reason you are temporarily unable to ship, or if you want to change an approved shipment plan, you must delete all shipments in that plan before you begin shipping any shipment in that plan
Warehousing and Distribution
Why is Amazon charging a low inventory fee?
When sellers keep inventory levels too low for a long time, Amazon can’t optimally place inventory in advance at warehouses closest to customers. This will slow delivery speeds, increase Fulfillment by Amazon costs, and also affect sellers’ sales velocity and product conversion.
Do I need to pay the low inventory cost coverage fee if my product is out of stock?
No. Amazon does not charge a low inventory cost coverage fee when a product is out of stock (that is, the product has no sellable inventory in the Amazon fulfillment network).
How do inbound delays (for example, delays in receiving inbound products) affect historical days of supply?
The low inventory cost coverage fee is calculated by dividing the average daily number of inventory units by the average daily number of shipped units over the long term (past 90 days) and the short term (past 30 days). A minor inbound delay will not affect your long-term historical days of supply metric (past 90 days). Amazon recommends managing products’ long-term (past 90 days) historical days of supply to avoid this fee.
How will the low inventory level fee affect different product types (such as seasonal products)?
Different products with different sales volume may be impacted differently by the fee. However, you can minimize or avoid the fee by sending in additional units such that the product’s short-term (last 30 days) historical days of supply exceeds 28 days, or by managing your product’s long-term (last 90 days) historical days of supply. For specific seasonal product examples, go to the Seller Central Help page.
What is the relationship between Fulfillment by Amazon minimum inventory level metrics, historical days of supply, and the low inventory cost coverage fee?
Minimum inventory levels are a forward-looking metric that can help you plan future Fulfillment by Amazon inventory replenishment. We use Amazon’s inventory management and machine-learning models, while also considering factors such as demand forecasts and replenishment settings, to customize minimum inventory levels for each product. Keeping your inventory above this minimum level can help improve delivery speed and reduce the risk of incurring low inventory cost coverage fee. For more information, go to Fulfillment by Amazon Inventory Overview.
Historical days of supply is a backward-looking statistical metric that is used as the basis for the low inventory level fee. When the historical days of supply metric is low, it means the product’s inventory level has been low in the past, so the corresponding fee applies.
What should I do if capacity limits prevent me from sending in products with low inventory levels?
To manage inventory efficiently, keep the amount of inventory you hold balanced: not too much (excess), and not too little (low inventory or out of stock). If you are unable to send in products with low inventory levels due to capacity limits, we recommend taking the following actions to reduce excess inventory: increase sell-through, create liquidation orders, or request inventory returns or disposals through removal orders. Go to FBA Inventory and identify products with excess inventory.
