How to Send Products to Amazon FBA in 2026 (Step-by-Step Walkthrough)

If you sell on Amazon, one of the smartest ways to scale your business is by using Fulfillment by Amazon (FBA). It means Amazon stores your products, packs them, and ships them to customers for you. In 2026, the process of sending your products to Amazon FBA involves four main steps: creating a shipping plan in Seller Central, labeling your items correctly, packaging them according to Amazon’s rules, and sending them to the assigned fulfillment center through an approved carrier.

Done right, this process saves you time, reduces errors, and helps your products qualify for Prime delivery, which often leads to more sales.

Key Takeaways:

What Do You Need Before Sending Products to Amazon FBA?

Before you can ship anything to Amazon FBA, you need to make sure your account, listings, and products are fully set up. This saves you time later and helps you avoid shipment issues, delays, or even inventory rejections.

Here’s what you need to have ready:

1. A Professional Amazon Seller Central Account

You must have an active Amazon Seller Central account with FBA enabled. Without this, you can’t create shipping plans or send inventory to Amazon fulfillment centers. Make sure your account is verified and approved for the regions you want to sell in.

2. A Product Listing with an ASIN or SKU

You can only send products to FBA that are connected to a live listing. This means you must either:

• Create a new listing for your product
• Or match it to an existing ASIN on Amazon

Each product must have a unique SKU (Stock Keeping Unit) for inventory tracking. This connects your physical item to the digital listing in Amazon’s catalog.

3. FNSKU Barcodes Assigned to Each Unit

Amazon uses the FNSKU (Fulfillment Network Stock Keeping Unit) to track your products inside its warehouses. Every FBA unit needs a scannable barcode that links it to your seller account.

You can:

• Print FNSKU labels yourself
• Or use the Amazon Label Service (extra cost per unit)

If you sell products with manufacturer barcodes, you must choose your barcode type in Seller Central settings.

4. Compliance with Amazon’s Product Restrictions

Amazon restricts certain product categories and items from being fulfilled through FBA. You must check whether your products:

• Require approval (like topical creams, supplements, electronics)
• Fall under hazardous materials (hazmat)
• Have any storage limitations or expiration requirements

Use Amazon’s Product Compliance Portal to check eligibility. Failing to do this may get your inventory rejected on arrival.

5. Correct Prep Requirements for Each Product

Every product you send to FBA must meet Amazon’s prep guidelines, which depend on the item type. For example:

• Liquids need to be sealed and leak-proof
• Fragile items require bubble wrap or foam
• Clothing must be folded, bagged, and labeled
• Multipacks and bundles need to be clearly marked

Amazon provides SKU-specific prep instructions in your shipment workflow. If you skip this step, you might face prep service fees or inventory delays.

6. A Valid Ship-From Address

You must enter the correct ship-from address in your shipping plan. This tells Amazon where the inventory is coming from, whether it’s your warehouse, a supplier, or a prep center. The address affects how Amazon assigns the destination fulfillment center.

How Do You Create an Amazon FBA Shipping Plan?

Creating a shipping plan is the first step to moving your inventory into Amazon’s fulfillment network. This plan tells Amazon what products you’re sending, how many units, where it’s coming from, and how it’s packed. Without it, Amazon will not receive your shipment.

The entire process happens inside your Amazon Seller Central account using the Send to Amazon workflow.

Step 1: Go to the “Send to Amazon” Section in Seller Central

Log into Seller Central and go to your Manage All Inventory page. Select the SKUs you want to send and click “Send/Replenish Inventory.” This opens the Send to Amazon tool, which is the updated shipping plan builder for 2026.

Step 2: Confirm the Ship-From Address

You’ll need to enter the ship-from address, which could be your warehouse, a supplier, or a prep center. This address helps Amazon decide which fulfillment center will receive your shipment. A valid address ensures correct routing and fewer delays.

Step 3: Choose How Your Inventory is Packed

Amazon needs to know whether your items are packed as individual units or as case-packed boxes:

• Individual units: Mixed SKUs or quantities in the same box
• Case-packed: Same product and quantity in every box

Make sure to select the right type. Incorrect selections can lead to repackaging fees or shipment rejection.

Step 4: Enter the Number of Units Per SKU

Next, tell Amazon how many units of each SKU you’re sending. Be precise. Amazon uses this data to expect and track the correct number of items at check-in. Inaccurate quantities can cause inbound shipment errors and delays.

Step 5: Review Fulfillment Center Assignments

In 2026, Amazon will use Smart Distribution, which means your inventory may be split between different fulfillment centers to improve delivery times. Based on your ship-from location and item types, Amazon will assign one or more destination warehouses.

You can choose to accept the split or pay for the inventory placement service to send everything to one center.

Step 6: Print Labels (if applicable)

If you’re applying your own FNSKU labels, this is where you download them. Each label must match the product’s SKU and barcode type. If you selected Amazon Label Service, Amazon will label the products for a small fee per unit.

Step 7: Approve and Confirm the Shipment Plan

Once all the details are correct, review your summary. Amazon will generate a shipment ID, assign destination centers, and allow you to continue with box-level details. Click “Work on Shipment” to move forward with packaging and shipping.

Key Things to Remember

• Always double-check your SKUs, quantities, and packaging type
• Be sure the ship-from address is accurate
• Understand that Smart Distribution may split shipments
• Select the correct labeling option based on your workflow
• Download or print the FNSKU labels before you pack

How Should You Label Products for Amazon FBA?

Every product you send to Amazon FBA must have a scannable label that links it to your seller account. Amazon uses these labels to track, receive, and store your inventory inside their fulfillment centers. If your products are not labeled correctly, they may be rejected, delayed, or misrouted during check-in.

The most important label Amazon uses for FBA is called the FNSKU.

What is an FNSKU Label?

FNSKU stands for Fulfillment Network Stock Keeping Unit. It’s a barcode that Amazon requires for all FBA products. This label connects your inventory to your seller account, not just to a general product listing.

Each FNSKU is unique to your offer. Even if multiple sellers list the same product, Amazon uses FNSKU to separate your stock from others.

How Can You Apply FBA Labels?

You have two options:

1. Apply Labels Yourself
   You can download FNSKU labels directly from your shipping plan. Print them using a laser printer and place each label on a flat, visible surface of the product. The barcode must be easy to scan and not covered by shrink wrap or seams.
2. Use Amazon Label Service
   If you prefer, Amazon can label your products for you. This service costs around $0.30 per unit, and you must choose it during shipment creation.

Label Placement Rules You Must Follow

Amazon has strict requirements for label placement:

• Labels must cover any existing manufacturer barcodes
• Use a white label with black ink (standard barcode format)
• The label must be on the outside of the product or packaging
• Do not place labels over corners, curves, or seams
• If using poly bags, place the label on the bag surface, not the product inside

If a product is missing a readable FNSKU, it cannot be received into inventory.

What If You’re Using Manufacturer Barcodes?

You can choose to use manufacturer barcodes (UPC or EAN) if your product qualifies. In this case, Amazon tracks your inventory using the product’s existing barcode instead of FNSKU. However, this setting must be enabled in your FBA account under Barcode Preferences.

Keep in mind:

• Manufacturer barcode tracking can mix your inventory with other sellers’ stock
• FNSKU is preferred for private label and brand-controlled products

Common Labeling Mistakes to Avoid

Avoid these errors to prevent delays and fees:

• Printing blurry or smudged barcodes
• Placing labels over seams or wrapping
• Forgetting to remove or cover old barcodes
• Sending units with missing labels
• Using inkjet printers for barcode labels

How Do You Prepare and Package Products for Amazon FBA?

Before you send your products to Amazon FBA, you need to make sure every unit is packed according to Amazon’s FBA prep and packaging requirements. These rules protect your items during storage and shipping, reduce damage rates, and ensure Amazon can receive them without delays.

Failing to follow the correct prep steps can lead to extra fees, shipment rejection, or inventory delays.

Why Proper Prep Matters

Amazon scans and checks each unit when it arrives at the fulfillment center. If your product isn’t packed safely or doesn’t meet Amazon’s prep standards, it might be flagged for repackaging, delayed during check-in, or even returned.

Well-prepped products:

• Move faster through Amazon’s receiving process
• Avoid damage during handling and transport
• Meet Prime shipping and quality standards

How to Know What Prep is Required for Your Product

Amazon gives you SKU-specific prep instructions inside your shipping plan. These instructions tell you exactly what each product needs based on:

• Product category
• Material type
• Shape and weight
• Risk level (e.g., fragile or sharp items)

If you’re not sure what prep your product needs, use the FBA Prep Requirements Tool in Seller Central.

Common FBA Prep Types and When to Use Them

Below are the most common prep requirements Amazon expects, along with when they apply:

Prep Type	Use Case	Required Materials
Poly Bagging	Apparel, loose items, powder-based goods	Clear poly bags, suffocation label
Bubble Wrap	Fragile items like glass or electronics	Bubble wrap, tape
Boxing	Heavy or sharp items that need extra support	Cardboard boxes, edge protectors
Taping	Liquids and items with open lids	Tape that fully seals the item
Labeling	Multipacks, bundles, expiration-dated items	“Sold as set” or expiration label

Packaging Rules to Follow for All Products

Amazon has strict packaging guidelines. Here are the key rules to follow for any item:

• Every unit must be protected and enclosed (no exposed parts)
• Poly bags must be at least 1.5 mil thick and fully sealed
• Poly bags larger than 5 inches need a suffocation warning
• Boxed items must not collapse under pressure
• No packaging should obstruct scannable barcodes
• Each unit must be prepared for individual sale unless it’s part of a bundle

What If You Don’t Want to Do the Prep Yourself?

You can choose to use Amazon’s FBA Prep Service. Amazon will prepare, bag, and label your items for you. This saves time, especially for high-volume shipments.

Here’s what to know:

• Fees range from $1.00 to $2.30 per unit, depending on prep type
• You must enable this option when creating your shipping plan
• Amazon applies prep based on your selected SKU settings

Products That Need Special Packaging Attention

Some products need extra care when being prepped for FBA:

• Glass or ceramic items: Must be fully wrapped in bubble wrap and boxed
• Sharp objects: Blades and tools need to be fully covered and secured
• Liquids: Must be double-sealed and leak-proof
• Clothing: Should be folded, placed in a poly bag, and labeled with size
• Multipacks or bundles: Need clear “Sold as Set” labels

Not following these specific rules can cause Amazon to hold, return, or rework your shipment.

How Do You Ship Your Products to Amazon Fulfillment Centers?

Once your products are labeled and prepped, the next step is getting them safely to the right Amazon fulfillment center. This part of the process involves choosing a shipping method, preparing your boxes or pallets, and generating the correct labels in Seller Central.

Amazon offers different inbound shipping options, and each one has its own requirements.

Choose the Right Shipping Method for Your Inventory

Amazon allows three main shipping options for FBA inventory:

1. Small Parcel Delivery (SPD) – Use this when you’re sending boxes individually, often through carriers like UPS or FedEx. Each box is labeled and tracked separately.
2. Less Than Truckload (LTL) – Choose this if you’re sending multiple boxes on a single pallet. This is ideal for medium to large shipments.
3. Full Truckload (FTL) – Best for large shipments that fill an entire truck. FTL shipments must follow Amazon’s pallet and delivery rules strictly.

Use Amazon Partnered Carriers for Cost Savings

Amazon has partnerships with major carriers like UPS and FedEx. These carriers offer discounted rates to FBA sellers through the Amazon Partnered Carrier Program.

If you choose a partnered carrier:

• Rates are often lower than market shipping prices
• You can print prepaid labels directly from Seller Central
• Tracking updates are automatically sent to Amazon

This option works best for SPD shipments, especially if you don’t have your own freight account.

Know the Box Requirements Before Shipping

Amazon has clear box requirements for all FBA shipments. Boxes that don’t meet these rules may be delayed or rejected at the fulfillment center.

Key rules include:

• Each box must weigh no more than 50 lbs, unless it contains one oversized item
• The maximum box dimensions are 25 inches on any side, unless approved
• Use strong, corrugated boxes in good condition
• No box should have old shipping labels or branding
• Barcodes must be visible and not covered

For shipments with multiple SKUs, be sure to include box content information during shipment creation.

Shipping Labels and Placement

After you complete your shipping plan in Seller Central, Amazon will generate box labels. These labels help Amazon identify each shipment and route it to the correct receiving dock.

Here’s how to handle them:

• Download and print the labels directly from your shipment summary
• Use a laser printer for clean, scannable barcodes
• Attach one label to each box on a flat surface
• Avoid placing the label over seams or corners
• Place the label next to the FNSKU barcode, not over it

If you’re shipping via LTL or FTL, you’ll also need pallet labels placed on each side of the pallet.

Pallet Guidelines for LTL and FTL Shipments

If you’re shipping on pallets, you must follow Amazon’s pallet configuration requirements:

• Use standard 40 x 48-inch wooden pallets
• Pallet height must not exceed 72 inches, including the pallet
• Stretch wrap each pallet securely
• Label each pallet on all four sides
• No overhanging boxes or unstable stacking

Amazon requires scheduled delivery appointments for all LTL and FTL shipments. You can book these through the Carrier Central portal or your freight provider.

What Are the Common Mistakes to Avoid When Sending to FBA?

Many sellers run into avoidable problems when sending products to Amazon FBA. These mistakes can delay check-in, cause added fees, or result in rejected shipments.

• Missing or inaccurate box content information can slow down receiving and trigger manual checks. Always confirm SKUs, unit counts, and box dimensions match your shipping plan.
• Using the wrong barcode type, such as UPC instead of FNSKU, may cause your inventory to be misrouted or rejected. Every unit must have a clear, scannable FNSKU label.
• Skipping product prep, like bubble wrapping fragile items, sealing liquids, or applying suffocation warnings on poly bags, leads to damaged goods or non-compliance fees.
• Exceeding the 50-pound box limit without a “Team Lift” or “Heavy Package” label causes safety violations. Follow Amazon’s box weight and size requirements strictly.
• Mixing SKUs in a case-packed box violates packaging policies. Use individual product type if sending multiple SKUs in the same shipment.
• Shipping to the wrong fulfillment center causes delays or shipment rejection. Always follow the assigned warehouse address from your shipping plan.
• Poor shipping label placement, such as covering seams or placing labels over the FNSKU, prevents scanning. Apply labels on a flat, visible surface using a laser printer.

Avoiding these issues helps your inventory get checked in faster, prevents extra fees, and protects your FBA performance metrics.

What Costs Are Involved in Shipping to Amazon FBA?

Shipping products to Amazon FBA comes with several costs that affect your margins. The most common fees include inbound shipping, labeling, prep, storage, and removal.

• Inbound shipping costs vary by method. Using Amazon Partnered Carriers for Small Parcel Delivery (SPD) typically costs between $0.15 and $0.35 per unit. LTL and FTL rates depend on pallet size, weight, and zones.
• Labeling fees apply if you let Amazon apply FNSKU labels. This service costs around $0.30 per unit and is added to your account automatically.
• If Amazon handles product preparation, you’ll pay FBA Prep Service fees, ranging from $1.00 to $2.30 per unit based on prep type like bubble wrap, poly bagging, or taping.
• Monthly storage fees are charged based on your inventory volume. Standard-size items cost around $0.87 per cubic foot. These increase during Q4, reaching up to $2.40 per cubic foot.
• Amazon also charges long-term storage fees for units stored over 365 days. This is $6.90 per cubic foot or $0.15 per unit, whichever is higher.
• If you remove unsold inventory, removal fees range from $0.50 to $0.60 per unit. Disposal fees are similar.

Here’s a quick breakdown:

Fee Type	Average Cost (2026)
Inbound Shipping	$0.15 – $0.35 per unit (SPD)
Labeling	$0.30 per unit
Prep Service	$1.00 – $2.30 per unit
Storage (Standard)	$0.87 per cubic foot/month
Storage (Q4)	Up to $2.40 per cubic foot/month
Long-Term Storage	$6.90/cu ft or $0.15 per unit
Removal	$0.50 – $0.60 per unit

Managing these costs starts with choosing the right shipping method, labeling products yourself, prepping items correctly, and keeping inventory turnover high to avoid long-term fees.

What Tools Can Help Automate Amazon FBA Shipments?

If you’re sending products to Amazon FBA regularly, using the right tools can save you time, reduce errors, and make your shipping process smoother. These tools help with shipment creation, label printing, inventory tracking, and restocking decisions.

• Send to Amazon is Amazon’s built-in tool that lets you select SKUs, confirm labeling, print box labels, and choose partnered carriers—all in one place. It’s ideal for standard FBA shipments.
• InventoryLab connects directly to your Seller Central account. It helps you create shipments, print FNSKU labels, and track profitability per SKU. Many sellers use it to manage both inventory and margins.
• RestockPro is great for planning. It forecasts when you need to restock based on sales, supplier lead times, and current inventory. It can also generate purchase orders and track shipments.
• ShipStation works well if you sell on multiple channels like Amazon, eBay, or Shopify. It helps you compare carrier rates, print labels in bulk, and manage all shipments from one dashboard.
• Jungle Scout’s Inventory Manager is made for private label sellers. It shows sales trends, predicts when stock will run out, and helps plan reorders in time to avoid stockouts.

Here’s a quick comparison:

Tool	Best For	Key Feature
Send to Amazon	Shipment creation	Amazon’s native tool
InventoryLab	Profit tracking	FNSKU labels, ROI, shipment builder
RestockPro	Restock planning	Forecasting and lead time tracking
ShipStation	Multi-channel shipping	Carrier rate comparison
Jungle Scout	Private label sellers	Sales forecasts and reorder alerts

For smaller volumes, Amazon’s built-in tools may be enough. But if you ship often or manage a lot of SKUs, automation tools like these can help you stay accurate and save time.

FAQs About Sending Products to Amazon FBA

What happens if I send inventory to FBA without a listing?

You cannot send inventory to Amazon FBA without linking it to a product listing. Every item must have an active ASIN or SKU in Seller Central. Without it, Amazon will not know how to process or store your inventory.

Can I use a 3PL or prep center to send shipments directly to Amazon?

Yes, you can use a third-party logistics (3PL) provider or prep center to prepare and ship products to Amazon FBA. Just make sure you use the correct ship-from address when creating the shipping plan in Seller Central.

How do I handle expired or short-dated products in FBA?

If your products have an expiration date, Amazon requires the date to be clearly labeled on each unit. Products must have at least 90 days of shelf life remaining when they arrive at the fulfillment center. Expired items will be removed or disposed of by Amazon.

Can I send inventory from multiple suppliers in one shipment?

Yes, but you must combine the products into one shipping plan and provide accurate box content information for each box. Each unit must follow FBA prep and labeling rules, regardless of where it was sourced.

What is Amazon’s inventory placement service?

Inventory Placement Service lets you ship all your inventory to a single Amazon fulfillment center, instead of multiple ones. This reduces shipping complexity but comes with extra fees per unit. You can enable it in your FBA settings under Inbound Settings.

Does Amazon allow reusable packaging or boxes for FBA shipments?

No, Amazon requires new, single-use shipping boxes that are clean, undamaged, and strong. Reused or branded boxes are not allowed for inbound shipments and may be rejected at the warehouse.

How long does Amazon take to make inventory available after delivery?

After delivery, it can take 1 to 3 business days for Amazon to check the inventory. During peak seasons or if there are prep issues, this may take longer. You can monitor status updates in the Shipping Queue in Seller Central.
