Yes, and Amazon says so itself: its Multichannel Fulfillment page names MCF as one example of a 3PL. MCF uses the stock you already hold in FBA to ship orders placed on your own website or other channels, in 2 business days on Expedited or 3 on Standard.

Is Amazon a 3PL or a 4PL?

Amazon's fulfillment services are 3PL services from a seller's side: FBA, MCF and AWD all store and move your goods through Amazon's own buildings. A 4PL does a different job, managing several 3PLs and carriers on a shipper's behalf without running a warehouse floor itself.

Is FBA the same thing as an Amazon fulfillment center?

No. FBA is the program you enroll products in, and fulfillment centers are the buildings where Amazon stores and ships them. One seller's FBA stock is usually spread across several of those buildings near customers, which is the work Amazon's inbound placement fee pays for.

Does Amazon still prep and label inventory for FBA?

Not in the US. The service ended on January 1, 2026, and a shipment created after that date that turns up unprepped loses reimbursement for any units that are damaged or cannot be traced. Sellers now prep in-house, have the manufacturer do it, or hire a prep provider.

Can a 3PL send inventory into FBA for me?

Yes. A 3PL can receive your containers, prep and label units to Amazon's rules, hold the bulk stock and ship replenishment into FBA on a schedule you set. Amazon also keeps a list of vetted FBA prep providers, and its own AWD service stores bulk stock and refills FBA automatically.

Can I use FBA inventory for orders from my own website?

Yes, through Multichannel Fulfillment. Amazon offers more than 100 prebuilt integrations, Shopify and WooCommerce among them, and both channels then draw on 1 pool of stock. MCF fulfillment fees rose by $0.30 per unit on average in 2026.

How much does FBA charge per order?

It depends on size tier, shipping weight and price. Outside peak in 2026 the fee starts at $2.43 for a small standard item of 2 oz or less priced under $10, and a large standard item of 1 to 1.25 lb priced $10 to $50 pays $5.04, both before the 3.5% surcharge. Storage and the referral fee come on top.

Is FBA cheaper than a 3PL?

Sometimes, and only a like-for-like comparison tells you. FBA's per-unit fee already includes postage, so set it against a 3PL's pick and pack fee plus the postage it bills. Prime eligibility on FBA listings and the fees for slow or aged stock both belong in that comparison.

Is Amazon FBA a 3PL? What It Does and Where It Stops

Yes, Amazon FBA is a 3PL for the orders you sell on Amazon: you send stock to Amazon's fulfillment centers, and Amazon stores it, picks, packs and ships each order, and handles customer questions and returns. What sets it apart is that Amazon also runs the store and writes the rules. Below: what FBA covers, its 2026 fees, how MCF and AWD extend it, and when an independent 3PL fits better.

FBA does a 3PL’s job for your Amazon orders

Amazon describes Fulfillment by Amazon as a program that lets sellers hand order fulfillment to Amazon and offer free 2-day shipping through Prime. You send products into Amazon’s network, and Amazon picks, packs and ships each order, then handles the customer service and returns that follow. Amazon’s FBA page puts that network at hundreds of fulfillment centers worldwide.

That list is the job description of an independent third-party logistics provider: take in a brand’s stock, keep it on shelves, turn each order into a labeled parcel and deal with what comes back. On the work alone, FBA is a 3PL. The differences sit in whose orders it ships and who sets the terms.

Job	FBA	An independent 3PL
Receiving stock	Into Amazon’s fulfillment centers, booked through Send to Amazon	Into the 3PL’s building, counted against your advance ship notice
Storage	Billed monthly on cubic feet, with surcharges on aged stock	Billed by pallet, bin or shelf on the 3PL’s rate card
Pick, pack and ship	Amazon orders, with postage inside the fee	Every channel you connect, with postage usually its own line
Customer service	Amazon answers buyers about FBA orders	Stays with you
Returns	Amazon processes them	The 3PL receives and grades them under your rules
Prep and labeling	Your job since January 1, 2026	Usually sold as a service
Orders from other channels	Through MCF, a separate service	Part of the standard setup
Packaging	Amazon’s, or the product’s own box under SIPP	Your boxes, inserts and tape

The last 3 rows carry the real difference. A 3PL works for you across every channel and packs to your spec. FBA was built for the Amazon store, and Amazon, as the store’s operator, writes the rules, sets the fees and decides which products it accepts.

Sellers who would rather ship Amazon orders themselves use what Amazon calls Fulfilled by Merchant, and plenty of them split their catalog between the two, keeping compact, quick-selling items in FBA and bulky or slow ones on FBM.

MCF, AWD and Amazon’s other fulfillment services

Amazon sells FBA as one part of a wider set it calls Amazon Supply Chain Services, and registering for FBA opens 3 more straight away: Multichannel Fulfillment (MCF), Amazon Warehousing and Distribution (AWD) and Multichannel Distribution (MCD).

Service	What it does	Orders it serves	2026 pricing
FBA	Stores, picks, packs and ships; handles customer service and returns	The Amazon store	FBA fees up $0.08 per unit sold on average
MCF	Ships orders out of your FBA stock	Your website and other sales channels	Fulfillment fees up $0.30 a unit on average
AWD	Bulk storage that refills FBA and distributes to other channels	Feeds FBA and non-Amazon channels	Storage $0.48 per cubic foot a month in the East and South, $0.57 in the West

MCF is where Amazon’s own wording settles the question. Its Multichannel Fulfillment page lists the usual ways to fulfill ecommerce orders and names MCF as one example of a 3PL. It draws on the units already in FBA and delivers in 2 business days on Expedited or 3 on Standard.

Amazon lists more than 100 prebuilt integrations for MCF, Shopify and WooCommerce among them. On a Shopify store the platform routes each order and the warehouse behind the app does the physical work, the same split as with any 3PL a merchant connects.

AWD sits one step upstream: bulk storage with pay-as-you-go pricing and no seasonal surcharges, refilling FBA automatically for a 2026 transport fee of $1.40 per cubic foot. For brands on FBA, that is the job a 3PL’s reserve storage has long done.

What FBA charges in 2026

Amazon’s FBA cost list has 6 fee lines: a fulfillment fee per unit that pays for the pick, the pack and the postage, plus customer service and returns; monthly storage on your daily average volume in cubic feet; an aged inventory surcharge on stock held more than 181 days; a returns processing fee where Amazon offers free return shipping; per-item charges for removal, disposal and liquidation; and the inbound placement fee for spreading stock across fulfillment centers near customers.

Amazon’s 2026 fee summary put the average FBA rise at $0.08 per unit sold from January 15, 2026, after no increase in 2025, with no new fee types. Later in the year came 2 more changes: a 3.5% fuel and logistics surcharge on fulfillment fees from April 17, 2026, and holiday peak rates from October 15, 2026 to January 14, 2027.

The fulfillment fee follows size tier, shipping weight and price. Small standard items are charged on unit weight; large standard and bigger tiers on unit weight or dimensional weight, whichever is greater. These are Amazon’s 2026 fulfillment rates for products priced $10 to $50, before the surcharge:

Size tier and shipping weight	January 15 to October 14, 2026	Peak, October 15, 2026 to January 14, 2027
Small standard, 2 oz or less	$3.32	$3.51
Small standard, 2+ to 4 oz	$3.42	$3.61
Large standard, 4 oz or less	$3.73	$3.97
Large standard, 12+ to 16 oz	$4.60	$4.89
Large standard, 1+ to 1.25 lb	$5.04	$5.34
Large standard, 2+ to 2.25 lb	$5.92	$6.29

Products priced under $10 pay less: a small standard item of 2 oz or less costs $2.43 outside peak. Selling fees sit outside all of this: the Professional plan is $39.99 a month, and the referral fee is 15% of the sale price, with a $0.30 minimum, in categories such as Home and Kitchen and Pet Supplies.

Here is one non-peak month for a kitchen brand selling a $28 silicone baking set that ships at 1.1 lb, 1,000 orders of 1 unit each. The fee and surcharge are Amazon’s 2026 rates; storage, freight and prep are example ranges.

Sample month on FBA, 1,000 Amazon orders

FBA fulfillment fee (1,000 units at $5.04)	$5,040
Fuel and logistics surcharge (3.5%)	$176.40
Monthly storage (about 150 cubic feet)	$115 to $360
Inbound freight to Amazon (2 pallets)	$150 to $300
Prep and labeling by a provider (1,000 units at $0.40 to $1.00)	$400 to $1,000
Total	$5,881 to $6,876, or $5.88 to $6.88 an order

The $5.04 already pays for postage, so hold it against a 3PL's pick and pack fee plus postage, never the pick fee alone. The 15% referral fee, $4,200 on these sales, is owed whether FBA or you ship the order. In November the same unit costs $5.34 to fulfill.

Postage is what decides most attempts at comparing FBA with a 3PL’s rate card. A 3PL quoting $3.00 to pick and pack the same baking set has not yet bought the label, and on a parcel of that weight the label is usually the larger number.

Rules FBA sets that an independent 3PL does not

A 3PL signs a contract with you and adapts its floor to your products. FBA publishes a single set of rules for every seller, and the 2026 versions carry 3 that change how a brand plans.

Prep and labeling moved to you on January 1, 2026

Amazon’s prep service page sets out the change: from January 1, 2026, Amazon stopped prepping and labeling units bound for US FBA, and that covers stock arriving through AWD and Amazon’s other inbound services too. If a shipment created after that date turns up without the required prep and labels, units that are damaged or cannot be traced are not reimbursed. Every unit needs a scannable label that stays visible once prep is done.

Amazon offers 3 routes: prep in-house, hire a provider from its vetted list or one of your own, or certify eligible products for Ships in Product Packaging (SIPP), which can reduce prep and lowers the fulfillment fee on standard-size units.

Products FBA will not take

Under FBA’s product restrictions, a product Amazon lets you list can still be barred from its fulfillment centers. Most products the US Department of Transportation regulates as hazardous materials cannot go through FBA, and dated or temperature-sensitive goods must meet extra requirements. Breaking the rules can get inventory refused, disposed of or sent back, block future shipments, or lead to the selling account being deactivated. The dangerous goods FBA does accept carry their own fulfillment fees.

Fees for holding too little stock and too much

Once a product falls below 28 days of supply relative to customer demand, Amazon adds a low-inventory-level fee to each unit shipped, and from 2026 it measures that per variation (FNSKU) rather than per parent listing. At the other end, the aged inventory surcharge starts after 181 days. In 2026, items 12 to 15 months old pay the greater of $0.30 a unit or $6.90 per cubic foot a month, and a new tier past 15 months charges $0.35 a unit or $7.90 per cubic foot.

Amazon also sets FBA capacity limits, and it pitches AWD’s automatic refills as the way around both those limits and the low-inventory fee. A 3PL’s contract can carry long-term storage charges too, but those are terms negotiated with you.

When a separate 3PL fits better than FBA

An independent 3PL earns its fee where the work falls outside what FBA was built for:

Wholesale and retail accounts are growing. Retail accounts bring routing guides, case labels and delivery appointments, and a 3PL ships those alongside your parcels.
Your products are hazmat, dated or temperature-sensitive. Most DOT-regulated hazardous materials are barred from FBA, and a 3PL equipped for them can take what Amazon turns away.
The unboxing is part of the brand. Branded mailers, inserts, gift notes and kits are routine at a 3PL pack station, while FBA ships in Amazon’s packaging unless the product is certified to ship in its own.
You import by the container. A 3PL can receive 1,800 cartons, prep and label them to Amazon’s rules and send FBA what it needs every few weeks, which keeps you clear of both the 28-day and the 181-day lines.
You want terms you can negotiate. Minimums, storage rates and claim windows are agreed with a 3PL, while FBA’s fees change on Amazon’s notice, as the April 2026 surcharge showed.

FBA on its own stays the simpler choice when:

Amazon is most of your revenue. FBA listings are eligible for free 2-day Prime shipping, and the fee already covers postage and customer service.
Your catalog is small, light and quick-selling. Small standard items priced $10 to $50 pay $3.32 to $3.96 a unit outside peak in 2026, postage included.
Your manufacturer can ship prepped cartons straight in. A middle warehouse would add a fee and an extra transit leg with nothing to show for it.

Brands that run both have to tell the 3PL exactly when to ship into FBA and how much.

Getting stock into FBA in 2026

Whether the units leave your own room, a factory or a 3PL, the first shipment into FBA goes better when these are settled before the cartons are taped.
