Amazon Warehousing and Distribution (AWD) is Amazon’s bulk storage service. You ship cartons or pallets to an Amazon distribution center, they sit there at low-cost long-term rates, and Amazon automatically feeds stock into your FBA fulfillment centers as it sells. Think of it as the warehouse behind the warehouse.
That auto-replenishment loop is the whole appeal, and I think it solves a genuinely painful problem: FBA storage is expensive and capacity-limited, so most sellers end up renting a 3PL or a garage to hold overflow. AWD replaces that middle layer with Amazon’s own.
We manage inventory flows for client accounts, and I’ll give you the honest picture here: what AWD does well, the fee structure, and the seller profiles where I think it beats a third-party warehouse.
How does Amazon Warehousing and Distribution work?
The flow has four steps:
- Enroll from Seller Central. Go to the Inventory menu and look for the AWD (Store and Distribute) option. Enrollment itself is a few clicks for an existing professional seller.
- Ship inventory in bulk to an Amazon distribution center, either through Amazon Global Logistics or your own carrier and forwarder.
- Amazon stores it upstream. Your stock sits in the distribution network, outside your FBA storage limits, at rates well below FBA’s.
- Auto-replenishment moves it downstream. As FBA stock dips, AWD sends more to fulfillment centers on its own. You watch it happen in the shipping queue rather than building shipments by hand.
In my experience the pooled-inventory model matters more than it first appears. Your AWD stock counts as one pool that can serve FBA, and in Amazon’s multi-channel setup, other sales channels too. One inbound shipment, several destinations.
What AWD costs: the three fees
Amazon prices AWD with a simple structure, which is honestly its best feature after replenishment. I’ve found clients grasp it in one sitting, something nobody says about FBA’s fee schedule. There are three charges:
| Fee | What it covers | How it is charged |
|---|---|---|
| Storage | Holding your inventory | Per cubic foot, per month; higher rate in Q4 |
| Processing | Receiving and handling inbound stock | Per box or case, not per item |
| Transportation | Moving stock from AWD into FBA | Per cubic foot |
Exact rates change, and Amazon has adjusted them more than once since launch, so treat any blog post’s numbers (including old versions of this one) with suspicion. My advice: pull the current rate card from the AWD pricing page in Seller Central before you model a single cost.
Two structural points hold regardless of the current rates, and I’d build any comparison around them. First, AWD storage runs at a fraction of FBA’s rate, especially in Q4 when FBA storage costs spike hardest. Second, there are no long-term storage surcharges in AWD, which is exactly the fee that punishes slow movers inside FBA.
In our experience the math favors AWD most for sellers importing container loads two to four times a year: the bulk arrives, sits cheaply, and drips into FBA at the pace of sales.
AWD vs FBA: what each one is for
This confuses nearly every newer seller I talk to, so here is the clean division.
| FBA fulfillment centers | AWD distribution centers | |
|---|---|---|
| Purpose | Pick, pack, ship customer orders | Long-term bulk storage |
| Storage horizon | Weeks, ideally | Months, by design |
| Storage cost | High, plus aged-inventory surcharges | Low, no long-term surcharge |
| Capacity | Limited by your FBA capacity | Effectively unlimited for most sellers |
| Who moves stock in | You build shipments | Auto-replenishment does it |
They are not competitors. The way I explain it: FBA is the storefront shelf, AWD is the stockroom. The question is not “AWD or FBA” but “AWD or a third-party warehouse” for the stockroom role.
AWD vs a 3PL: my take
A good 3PL still wins if you need services AWD will not do: kitting, relabeling, quality inspection, returns processing, or forwarding stock to non-Amazon channels with your own branding. AWD stores and moves cases. It does not fix them. I’ve seen sellers discover that distinction at the worst possible moment.
AWD wins on integration. No coordination between your warehouse and your FBA shipments, no replenishment spreadsheet, no stockout because your 3PL’s dock was backed up during Q4. For a straightforward private-label catalog that sells mainly on Amazon, that simplicity is worth real money. If your products need inspection or prep before they are FBA-ready, that step still belongs before AWD, either at origin or through a prep and inspection workflow.
Eligibility, product rules, and size limits
AWD takes standard-size, non-perishable goods. The exclusions to know:
- Perishables and dangerous goods are out, as is anything on Amazon’s hazmat list.
- Excluded categories include jewelry, watches, shoes, gift cards, Amazon devices, groceries, and high-value items.
- Carton limits: boxes must stay under 25 x 25 x 36 inches and 50 lbs.
- Unit limits: individual SKUs under 18 x 14 x 8 inches and 20 lbs.
If your product is oversize, AWD is simply unavailable for it yet, and a 3PL remains your answer. We check these limits against supplier carton specs before every first shipment, because a two-inch overage voids the whole plan.
Who should actually use AWD?
I’d frame it as three profiles.
Strong fit: the importer. You bring in ocean freight from China several times a year, your products are standard-size, and capacity limits or Q4 fees have burned you before. AWD was practically designed for you, and in my view this profile should default to it. Pair it with our guide to shipping from China to Amazon FBA by ocean, since the container-to-AWD-to-FBA pipeline is the cleanest version of this system.
Situational fit: the multi-channel seller. If Amazon is your main channel but not your only one, pooled inventory helps, though check whether AWD’s distribution options cover your other channels the way you need before committing everything.
Poor fit: fast-turn or specialized catalogs. If your entire inventory sells through FBA within weeks of arrival, adding an AWD hop adds transportation fees and days without saving much storage. And if you need prep, kitting, or inspection, the missing services outweigh the cheap cubic feet.
Getting the inbound side right
Most AWD problems we see are really inbound problems: cartons over the size limit, mixed SKUs where the plan said single-SKU, or labels that refuse to scan. Amazon receives millions of boxes and has no patience for exceptions. Neither, frankly, do their receiving docks.
Three habits prevent nearly all of it:
- Lock your carton spec with the supplier in writing, against AWD’s limits, before production, not after.
- Inspect before it ships. A pre-shipment check at origin costs a small fee per lot and catches the packaging surprises that turn into receiving delays. This is precisely the gap our sourcing management service closes for import-heavy clients.
- Plan freight with AWD in mind. Ocean freight to a distribution center has different address and appointment requirements than FBA inbound; a forwarder who has done AWD deliveries before saves you the learning curve, and our global shipping and logistics team handles that leg end to end.
FAQ
What is Amazon Warehousing and Distribution?
AWD is Amazon’s long-term bulk storage service. You ship inventory to an Amazon distribution center at low storage rates, and Amazon automatically replenishes your FBA fulfillment stock from it as you sell.
Is AWD cheaper than FBA storage?
For storage, considerably, and AWD has no long-term storage surcharges. You do pay processing and transportation fees to move stock into FBA, so the total math depends on how long inventory sits. Slow and steady sellers benefit most.
Does AWD replace FBA?
No. FBA still picks, packs, and ships every customer order. AWD sits upstream of FBA as bulk storage and feeds it automatically. Most AWD users run both together.
What products are not allowed in AWD?
Perishables, dangerous goods, and several excluded categories including jewelry, shoes, watches, gift cards, groceries, Amazon devices, and high-value items. Cartons must be under 25 x 25 x 36 inches and 50 lbs.
How does AWD auto-replenishment work?
Amazon monitors your FBA stock levels and creates replenishment shipments from your AWD inventory automatically when levels run low. You can track the transfers in your shipping queue and adjust settings if you want more control.
Should I use AWD or a third-party warehouse?
Use AWD if your catalog is standard-size, mostly Amazon-bound, and needs no prep or kitting; the integration and pricing are hard to beat. Use a 3PL if you need inspection, relabeling, kitting, returns handling, or serious multi-channel distribution.
