AWD (Amazon Warehousing and Distribution) - Amazon Glossary

Amazon Warehousing and Distribution (AWD) is a bulk storage and auto-replenishment service that keeps inventory "upstream" in Amazon’s supply chain. It allows sellers to bypass FBA capacity limits by storing stock in secondary facilities that automatically transfer units to fulfillment centers based on real-time consumer demand.

Why Does AWD Matter?

AWD provides a critical buffer against stockouts and volatile FBA storage costs. By utilizing AWD, sellers can avoid aggressive Q4 surcharges, maintain a lean Inventory Performance Index (IPI), and ensure their products remain "buyable" even while in transit, directly stabilizing long-term cash flow.

How is AWD Storage Calculated?

As of January 15, 2026, AWD fees are split primarily between regional storage and transportation. To calculate the monthly cost of holding inventory in AWD versus FBA, use the following formula:

$$Monthly\ Cost = (V_{cuft} \times R_{Storage}) + (V_{cuft} \times R_{Transport}) + (N_{boxes} \times F_{handling})$$

Where:

• $V_{cuft}$ is the total volume in cubic feet.

• $R_{Storage}$ is the regional rate ($0.57/cu ft for West, $0.48/cu ft for East/South).

• $R_{Transport}$ is the base transportation rate ($1.40/cu ft).

• $F_{handling}$ is the box handling fee ($0.05 per box).

Why Use AWD Instead of Standard FBA Storage?

The primary advantage of AWD in 2026 is the avoidance of seasonal price spikes. While FBA storage rates can triple during the holiday peak, AWD rates remain steady year-round.

Real-World Scenario: The 2lb Silicone Spatula

A seller in the Home & Kitchen category has 5,000 units (approx. 200 cubic feet) of silicone spatulas.

• Correct Approach: The seller ships the 5,000 units to an AWD facility in the East Region in September. They pay a flat $0.48 per cubic foot. As units sell, Amazon automatically moves 500 units at a time to an FBA fulfillment center. The seller avoids the $2.40/cu ft FBA peak fee and ensures they never hit their FBA capacity limit.

• Common Mistake: A seller ships all 5,000 units directly to FBA in October. They are immediately hit with high peak storage fees and a low-inventory-level fee because their "days of supply" is too high for the FBA footprint, significantly eroding their net margin.

FBA vs. FBM Context

AWD is designed as a direct extension of the Fulfillment by Amazon (FBA) ecosystem. While it now supports Multi-Channel Distribution (MCD) for shipping to other retailers like Walmart or Target, its core value is the seamless auto-replenishment to FBA. Fulfillment by Merchant (FBM) sellers typically do not use AWD, as the system is optimized for Amazon’s internal logistics flow rather than individual customer parcel shipping.

What Are the Key 2026 AWD Updates?

Why did West Region fees increase?

Effective January 15, 2026, Amazon increased West Region AWD storage to $0.57 per cubic foot to account for higher operational costs in California and Washington. East and South regions remain the most cost-effective at $0.48 per cubic foot.

How does AWD affect IPI and Capacity?

In 2026, the IPI threshold for standard capacity was lowered to 350. Inventory stored in AWD does not count against your FBA capacity limit until it is moved to an active fulfillment center. This allows high-volume sellers to maintain massive "buyable" reserves without being penalized for "excess inventory" in the FBA network.

Is AWD inventory "Buyable" during transit?

Yes. One of the most powerful features of AWD is that listings remain active and "buyable" while inventory is moving from an AWD hub to an FBA center. This prevents the "out of stock" ranking death spiral that often occurs during traditional carrier delays.

SoldScope Expert Tip

In 2026, "Regional Rebalancing" is the most effective way to save on AWD. If your manufacturer is in Asia, the default is to ship to the US West Coast. However, by instructing your freight forwarder or Amazon Global Logistics (AGL) to route to an East or South AWD hub, you save $0.09 per cubic foot every single month. For a standard 40ft container's worth of volume, this rebalancing can save your business over $6,000 annually in storage costs alone.

FAQ

How to lower Amazon AWD fees?

The most direct way to lower fees is to enroll in the Smart Storage (10% discount) or Managed Storage (20% discount) programs. These require consistent sales velocity and volume commitments but effectively offset the 2026 price increases.

What are the box requirements for AWD?

Boxes must not exceed 25 inches on any side or weigh more than 50 lbs. AWD is strictly a palletized or case-packed service; small parcel deliveries (SPD) are not accepted at AWD upstream hubs.

Can I ship lithium batteries to AWD?

As of April 2026, Amazon expanded AWD eligibility to include certain lithium battery products (UN3480, UN3481, etc.). Sellers must ensure their Hazmat documentation is approved before creating an inbound shipment.
