Amazon FBA Shipping Requirements and Prep Guide
Amazon FBA Shipping Requirements and Prep Guide
Fulfillment by Amazon (FBA) lets you store your products in Amazon’s warehouses and have Amazon handle picking, packing, shipping, and customer service. But getting your inventory into Amazon’s fulfillment centers requires following strict prep and shipping requirements. Missing a single step can result in rejected shipments, additional fees, or inventory being returned at your expense.
Shipping rates and delivery times are estimates and may vary. Verify current rates directly with carriers.
How Amazon FBA Works
- You source or manufacture products
- You prep and label products according to Amazon’s requirements
- You ship inventory to Amazon fulfillment centers using Amazon’s partnered carriers or your own
- Amazon stores, picks, packs, and ships orders to customers
- Amazon handles customer service and returns for FBA orders
FBA products are eligible for Prime shipping, which can significantly increase your sales. However, FBA comes with storage fees, fulfillment fees, and strict prep requirements.
FBA Product Prep Requirements
Every product you send to Amazon must meet specific prep standards. Failure to comply results in extra fees or rejected inventory.
Labeling Requirements
| Label Type | When Required | Specifications |
|---|---|---|
| FNSKU barcode label | All FBA products (unless commingled) | Printed clearly, scannable, covers original UPC |
| Suffocation warning | Poly-bagged items | ”WARNING: To avoid danger of suffocation…” |
| Sold as set | Multi-item bundles | ”Sold as set --- do not separate” |
| Made in [Country] | Required by US customs for imports | Country of origin label |
FNSKU labels are unique Amazon identifiers that link each unit to your seller account. You can print them from Seller Central or use a thermal label printer. For printer recommendations, see Best Thermal Label Printers for Shipping Labels.
Packaging Requirements by Product Type
| Product Type | Prep Required |
|---|---|
| Fragile items | Bubble wrap + “Fragile” sticker + box with 2” cushioning |
| Liquids | Sealed in poly bag + upright orientation + “This side up” |
| Small items | Poly bag (min 1.5 mil thickness) with suffocation warning |
| Sharp items | Wrapped securely with blade/point protected |
| Apparel | Poly bag with suffocation warning, folded neatly |
| Glass | Bubble wrap + box-in-box packaging |
| Sets/bundles | Poly-bagged or shrink-wrapped together with “Sold as set” label |
| Expirable products | Expiration date visible on outside of packaging |
Box Requirements for Shipping to Amazon
| Requirement | Specification |
|---|---|
| Box dimensions | No side longer than 25 inches (standard) |
| Box weight | Maximum 50 lbs per box |
| Box condition | New or like-new boxes only (no heavy damage or staining) |
| Packing materials | No packing peanuts, shredded paper, or styrofoam |
| Void fill | Air pillows, full sheets of paper, or foam padding |

Creating an FBA Shipment in Seller Central
Follow these steps to create a shipping plan:
- Log into Seller Central and go to Inventory > Manage FBA Shipments
- Select products and specify quantities for each SKU
- Choose prep and labeling: Indicate whether you will prep/label or pay Amazon to do it
- Review shipping plan: Amazon assigns your inventory to one or more fulfillment centers
- Select carrier: Choose Amazon Partnered Carrier (discounted UPS rates) or your own carrier
- Print box labels: Apply Amazon-generated FBA shipment labels to the outside of each box
- Ship inventory: Drop off at UPS or schedule a pickup
Amazon Partnered Carrier vs. Your Own Carrier
| Factor | Amazon Partnered Carrier (UPS) | Your Own Carrier |
|---|---|---|
| Cost | Heavily discounted | Standard/negotiated rates |
| Ease of use | Integrated into Seller Central | Requires separate label |
| Tracking | Automatic in Seller Central | Manual entry required |
| Carrier options | UPS only | Any carrier |
| Best for | Most sellers | Sellers with better negotiated rates |
For most sellers, Amazon’s partnered carrier rates through UPS are the cheapest option. Rates are estimated at 50-70% below standard UPS retail rates.
FBA Fees Overview
| Fee Type | Typical Range | Notes |
|---|---|---|
| Fulfillment fee | $3.22-$6.00+ per unit | Based on size and weight |
| Monthly storage fee | $0.87-$2.40 per cubic foot | Higher Oct-Dec (peak season) |
| Long-term storage fee | $6.90 per cubic foot | For inventory stored 271-365+ days |
| Removal/disposal fee | $0.97-$1.78 per unit | To have Amazon return or dispose of inventory |
| Prep service fee | $1.00-$2.20 per unit | If Amazon preps your products |
| Label service fee | $0.55 per unit | If Amazon applies FNSKU labels |
Keeping inventory levels lean and avoiding long-term storage fees is critical to maintaining healthy margins.
Common FBA Shipping Mistakes to Avoid
-
Sending to the wrong fulfillment center: Always follow the shipping plan Amazon generates. Sending inventory to an unassigned warehouse results in rejection.
-
Using prohibited packing materials: Packing peanuts and shredded paper are not allowed.
-
Missing FNSKU labels: Units without proper labels get set aside and you are charged a labeling fee.
-
Exceeding box weight limits: Boxes over 50 lbs are rejected. Overweight boxes also risk damage during transit.
-
Shipping commingled inventory unintentionally: Unless you specifically opt into commingling, every unit needs an FNSKU label.
-
Not inspecting products before shipping: Quality issues discovered by Amazon can lead to stranded inventory and account health warnings.
Reducing Your FBA Shipping Costs
- Use Amazon Partnered Carriers for the deepest discounts on inbound shipping
- Optimize box sizes to minimize dimensional weight charges
- Send full pallets when possible (Amazon offers pallet-level discounts for large shipments)
- Use third-party prep centers if you lack warehouse space --- they can be more cost-effective than Amazon’s own prep fees for high-volume sellers
- Monitor inventory levels to avoid long-term storage fees while keeping stock levels sufficient to avoid stockouts
