Sending your first shipment to Amazon FBA is a clear sequence of steps — but the difference between a cheap, smooth shipment and an expensive, delayed one comes down to a few decisions most guides never mention: how Amazon splits your inventory across fulfillment centers, and whether you pay an inbound placement fee. This guide covers the full process and the placement, box-content, and fee-avoidance details that actually save you money in 2026.

Before you start

Have three things ready: an active FBA listing, the physical inventory on hand, and a laser or thermal printer (inkjet smudges and won't scan). Also decide up front whether you'll send case-packed stock (identical units, same count per box — simpler and cheaper) or individual units (mixed boxes, more handling). This one choice affects your fees later.

Step 1: Create your shipping plan

In Seller Central, open Manage Inventory → Send/Replenish Inventory. Confirm your ship-from address, pick the product, and enter your quantities. This is where the important decisions begin — because right after this, Amazon shows you your placement options, and that's where sellers quietly overpay.

Step 2: Understand shipment splits & the placement fee

Amazon no longer sends all your inventory to one place. When you create the plan, it offers placement options that trade off convenience against a per-unit inbound placement service fee:

• Minimal shipment splits — Amazon sends your stock to just 1–2 fulfillment centers. Simpler and cheaper on freight, but you pay an inbound placement fee (roughly $0.21–$3.95 per unit depending on size tier in 2026; about $0.30–$0.40/unit for standard-size items).
• Amazon-optimized shipment splits — Amazon spreads your inventory across 4+ centers and waives the placement fee entirely ($0). The catch: you're now creating more shipments to more destinations, so your freight and handling go up.

The right choice is a math problem, not a default: compare the placement fee you'd pay (units × per-unit fee) against the extra freight of shipping to more locations. For small, light, high-value items the placement fee is usually cheaper; for bulky, low-cost items, optimized splits often win.

How to qualify for $0 placement fees

You don't have to just accept the fee. Here's how sellers get inbound placement down to $0:

• Send 5+ identical boxes (or pallets) per SKU. Amazon-optimized placement generally requires at least five identical cartons per item — so consolidating a SKU into fuller, standardized case-packs unlocks the $0 option.
• Use Amazon Warehousing & Distribution (AWD). Inbound to AWD is exempt from placement fees — Amazon auto-distributes your stock to FCs and even waives storage-utilization surcharges. Ideal for bulk/wholesale sellers.
• Ship by pallet (freight). With the post-pack method, shipping 5+ pallets (LTL) can bring placement fees to near $0.
• Join SIPP (Ships in Product Packaging). Eligible products earn a fulfillment discount of about $0.04–$1.32/unit — which can offset or cancel out the placement fee.

Note: Amazon's fees and thresholds change periodically — always confirm the current rates and requirements in Seller Central before you commit a plan.

Step 3: Choose your barcode & prep

Choose the Amazon barcode (FNSKU) option so your inventory is tracked separately, not commingled with other sellers' stock. Confirm the prep each unit needs (poly-bag, bubble wrap, bundling). New to FNSKUs? See our FNSKU guide.

Step 4: Prep, pack, and protect

Apply the FNSKU to every unit (covering any existing barcode), poly-bag loose or soft items with a suffocation warning where required, bubble-wrap anything fragile, and assemble bundles as single labeled units — all to Amazon's current spec. Our prep requirements checklist has the full detail.

Step 5: Box up & provide box content info

Boxing has rules that carry their own hidden fees:

• Sturdy boxes, each under 50 lb (heavier needs a "Team Lift" label; over ~100 lb, "Mechanical Lift").
• Provide box content information — the exact SKUs and quantities in each box — via manual entry, a flat-file upload, or 2D barcodes. Skip this and Amazon charges a manual processing fee per unit.
• Case-packed shipments (identical SKU and count per box) are faster to enter, easier to receive, and help you hit the 5-box threshold for optimized placement.

Step 6: Print labels, book a carrier & ship

Amazon generates a box ID/shipment label for each box (apply it flat and scannable) and a carrier label. For small-parcel, the Amazon Partnered Carrier program usually gives the best rates and integrates tracking automatically. For pallets, arrange LTL freight. Then track everything under Inventory → Manage FBA Shipments until your units are checked in and live.

How a prep center makes all of this cheaper

A good prep center doesn't just label and box — it structures your shipment to minimize fees. We consolidate your SKUs into standardized case-packs (helping you qualify for $0-fee optimized placement), enter accurate box content to avoid manual processing fees, palletize for freight when that's cheaper, and can route bulk inventory through AWD. Combined with an under-1% error rate, that means your first shipment arrives compliant and costs less than doing it alone. Explore our FBA prep service to see what's included.
