Amazon FBA
Inbound placement, distributed inventory, and storage rule changes that reshape shipping plans.
Overview
Amazon's FBA inbound rules keep shifting, but the change with the broadest operational impact has been in how Amazon places inventory across its fulfillment network. Distributed inventory placement — splitting a single inbound shipment plan across multiple FCs chosen by Amazon's own placement algorithm — is now the default for most sellers, replacing the older model where a seller could simply send everything to one location. Consolidating to fewer FCs is still possible, but it now runs through a paid placement service rather than being the free, standard option it once was. For cross-border sellers who built their domestic prep and inbound logistics around shipping to a single FC, this is the change that actually reshapes freight planning — not any single fee adjustment.
Timeline
| Milestone | Window | Why it matters |
|---|---|---|
| Inbound shipment plan creation | Per shipment | Amazon's placement algorithm decides FC splits at plan creation — the seller doesn't choose the destination FCs by default |
| Distributed inventory (default) | Standard for most plans | A single shipment plan typically gets split across multiple FCs based on Amazon's network optimization, not seller preference |
| Paid consolidation option | Available per plan, fee-based | Sellers can pay a placement service fee to route inventory to fewer FCs — useful if your domestic prep center or 3PL is built around a single inbound point |
| Inbound appointment & receiving | Per FC, appointment-dependent | Each FC in a split plan needs its own inbound appointment — congestion at one FC only delays that portion of the plan, not the whole shipment |

Cross-border prep centers
If your domestic prep center is built around consolidating to one inbound point, the default distributed-inventory model now works against that setup — budget for either the placement fee or for shipping directly to multiple FCs
Large or heavy SKUs
Inbound placement fees and eligibility rules are typically steeper for oversize and heavy-bulky inventory — model placement cost into unit economics for these categories specifically
Inventory age & limits
Distributed inventory across more FCs often means inventory health metrics and storage limits get evaluated per-FC rather than as one pool — track this at the FC level, not just the account level
Prep Checklist
- ✓Confirm whether your current inbound plans run under the default distributed model or a paid consolidation option, and compare the cost of each
- ✓If your domestic prep/3PL setup assumes a single inbound destination, budget for the placement service fee rather than assuming free consolidation still exists
- ✓For oversize/heavy-bulky SKUs, check current placement eligibility and fee tiers before finalizing shipment plans — rules here change more frequently than for standard-size inventory
- ✓Track inventory health and storage limits at the FC level when inventory is split across multiple locations, not just at the account level
- ✓Re-check Seller Central program documentation each quarter — Amazon's inbound placement rules have changed more than once and don't always apply retroactively to existing plans

FAQ
Amazon's placement algorithm now splits inbound shipment plans across multiple FCs by default (distributed inventory). Consolidating to fewer FCs is still possible but now requires paying a placement service fee rather than being the free standard option.
