How to Ship Inventory to Amazon FBA: Labels, Boxes & Pallets

Shipping to Amazon FBA begins with creating a correct shipment plan in Seller Central and ends when Amazon scans and reconciles your units at the fulfillment center. To ship to Amazon FBA you must follow Amazon's shipment creation workflow, apply the correct SKU and carton labels (or use Amazon's labeling service), meet prep and carton constraints, choose the right carrier or partner carrier service for boxes or pallets, and confirm received quantities.

This guide walks you step-by-step through the practical actions sellers take when preparing goods for FBA: what to do in Seller Central, how to label and pack, pallet-handling rules, carrier considerations, common pricing and timing factors, mistakes to avoid, and a final, actionable checklist. Always verify current requirements in your Seller Central account before booking shipments.

Create A Shipment Plan

Start in Seller Central: use the Inventory > Manage FBA Shipments (or Send/Replenish Inventory) workflow to create a shipment plan. The plan assigns destination fulfillment centers (Amazon sometimes splits your quantities across multiple centers), specifies whether items are case-packed or individually shipped, and generates required shipment IDs and transfer labels.

Key points:

• Shipment Type: Choose between individual units and case-packed units—case-packed means every carton contains identical SKUs and quantities.
• Receive Method: Select whether Amazon should receive cartons and pallets via drop-off or carrier pickup; options vary by shipment size and location.
• Labeling Options: Opt to label items yourself, or select Amazon’s “FBA Label Service” for a per-item fee (verify fees in Seller Central).

Labeling SKUs And Cartons

Labels are often the top cause of receiving delays. Every sellable unit that requires Amazon identification must have an Amazon barcode (FNSKU) that Amazon can scan. If a product uses manufacturer barcodes and qualifies, you may enable stickerless, commingled inventory—but verify eligibility.

Carton labels identify the shipment and carton contents. After creating a shipment in Seller Central, print carton labels and affix one label to each carton on a flat surface; do not cover labels with tape or place labels on carton edges.

• FNSKU/UPC Labeling: Place the barcode on the outside of the packaging where it can be scanned without opening the box.
• Carton Labels: Apply one Amazon carton label per carton and ensure the SSCC or shipment ID is visible. For pallets, ensure each carton has its carton label and the pallet has a pallet ID label if required.

Prep Requirements And Carton Constraints

Amazon sets prep rules to protect products in their network. Typical requirements include poly-bagging small items, bubble-wrapping fragile goods, and taping liquids. Dimensions, weight limits, and carton construction must meet carrier and Amazon rules—overpacked or missized cartons can be refused or incur charges.

Common constraints:

• Carton Weight Limits: Keep individual carton weights within safe manual handling limits (Amazon often enforces a maximum single-carton weight—check Seller Central for current limits).
• Dimensions: Measure and declare carton dimensions accurately; dimensional weight can affect carrier selection and cost.
• Packing Integrity: Use corrugated cartons rated for the shipment weight and void-fill to prevent shifting. Unsecure cartons increase damage risk and chargebacks.

Partnered Carriers And Carrier Selection

Amazon offers partnered carrier rates for small parcel shipments in some regions; rates and services change, so verify availability in Seller Central. Partnered carriers can simplify drop-off and pickup and provide a direct integration for tracking and invoice reconciliation.

When selecting a carrier:

• Service Level: Balance speed versus cost—expedited services reduce transit time but raise transport costs and may not improve in‑fulfillment-center processing time.
• Integration: Choose carriers that integrate well with your shipping platform or 3PL for automated label printing and tracking updates.
• Pallet Freight: For large shipments consider LTL or full-truckload freight carriers experienced with Amazon deliveries; confirm Amazon delivery appointment and routing requirements before pickup.

Pallet Deliveries And Stacking Requirements

Many FBA inbound shipments arrive on pallets. Palletized deliveries require specific stacking, pallet type, and labeling to pass Amazon receiving. Amazon may mandate shrink-wrapping, pallet corner protection, and that cartons on a pallet contain only one shipment and be completely labeled.

Practical pallet rules:

• Pallet Construction: Use standard, sturdy pallets in acceptable condition (no broken boards). Many carriers and Amazon accept 48"x40" four-way pallets, but verify dimensions with the destination center.
• Stacking: Stack cartons squarely without overhang and center the load to prevent tipping. Secure with wrap and banding if necessary.
• Labeling: Place a pallet ID label on two sides of the pallet at chest height and ensure carton labels are visible on each carton.

Reconciling Received Units And Handling Discrepancies

After Amazon scans inbound shipments, they update your inventory. Reconcile the received quantities in Seller Central. If Amazon reports fewer units than shipped, open a case in Seller Central and provide the packing list, carrier proof of delivery, and photos. Keep detailed outbound manifests and proof-of-delivery until inventory is confirmed.

Best practices:

• Documentation: Retain the shipment packing list, carrier BOL (bill of lading) for pallets, and tracking numbers until reconciliation completes.
• Timeframe: Monitor inbound shipments daily for scan updates—report discrepancies promptly as evidence windows can be limited for claim filing.

Materials Checklist

• Labels: FNSKU or manufacturer barcodes and Amazon carton labels printed from Seller Central.
• Boxes: Corrugated cartons rated for weight with internal void fill.
• Pallets: Standard, undamaged pallets and stretch wrap, corner boards, banding as needed.
• Prep Supplies: Poly bags, bubble wrap, tape, hazard labels (if applicable).
• Documentation: Packing lists, commercial invoices for cross-border shipments, BOL for freight.

Step-By-Step Packing And Shipment Setup

1) In Seller Central, create a shipment plan and confirm destinations and quantities. 2) Decide label method (self-label or Amazon label service). 3) Prep each unit per Amazon prep requirements and apply FNSKU labels. 4) Pack units into cartons, verify counts, and affix carton labels (one per carton). 5) For pallet shipments, stack, wrap, and apply pallet labels. 6) Book carrier pickup or drop-off; secure a BOL for freight. 7) Track the shipment and verify Amazon’s receiving updates; reconcile any discrepancies.

Factors Affecting Price And Delivery Speed

Cost and transit time depend on parcel size and weight, shipment density (LTL or FTL for pallets), carrier service level, distance to the fulfillment center, and whether you use Amazon-partnered carriers. Dimensional weight pricing and additional Amazon fees (labeling, prep services, or removal/return fees) also affect total cost.

Mistakes To Avoid

• Incorrect Labels: Misplaced or missing FNSKUs and carton labels cause delays and potential chargebacks.
• Inaccurate Counts: Not verifying unit counts before shipping makes reconciliation harder and claims weaker.
• Poor Packaging: Using weak cartons or loose stacking increases damage risk and rework fees.
• No Documentation: Failing to keep packing lists and BOLs complicates claims and reconciliation.

Using A 3PL To Streamline Repeat Shipments

A 3PL can prep, label, repack, palletize, and manage shipments to Amazon FBA on scale. For sellers with recurring volume, a 3PL reduces complexity by batching SKU labeling, maintaining stock for quick replenishment, and booking carriers with Amazon experience. Confirm the 3PL understands Amazon routing and labeling rules and maintains traceable records for each outbound FBA shipment.

Final Checklist

• Shipment Plan: Created and confirmed in Seller Central.
• Labels: FNSKU and carton labels printed and applied correctly.
• Prep: Items prepped per Amazon rules (poly-bagging, bubble wrap, etc.).
• Packing: Cartons packed within weight/dimension limits and sealed.
• Pallets: Pallets stacked squarely, wrapped, labeled, and BOL complete.
• Carrier: Booked appropriate carrier/service; tracking and POD secured.
• Documentation: Packing list and photos retained until reconciliation.

In short, the Shipping process to Amazon FBA combines accurate shipment planning, correct SKU and carton labeling, careful prep and packaging, and the right carrier choices to ensure units are accepted and reconciled quickly. Verify Amazon’s most recent inbound and prep policies in Seller Central before every shipment and consider a 3PL for repeat, scaled shipments to reduce handling errors and speed replenishment.
