Inbound Placement Service Fee (IPSF)
The Inbound Placement Service Fee (IPSF) is the per-unit charge introduced in 2024 for shipping FBA inventory to a small number of Amazon receiving centres instead of splitting it across multiple fulfilment centres. It rewards split shipments and penalises consolidated ones.
The Inbound Placement Service Fee (IPSF) is a per-unit charge Amazon introduced in March 2024. It covers the internal cost of distributing inventory across Amazon's fulfilment-centre network when the seller ships to fewer receiving centres than Amazon would prefer.
The economic intent: shift the work (and cost) of network distribution back onto sellers who refuse to split inbound shipments.
How it works
When you create an FBA shipment, Amazon proposes one or more placement options:
| Option | Sellers ship to | IPSF |
|---|---|---|
| Amazon-Optimised Shipment Splits | 4–5 FCs, distributed by Amazon | $0 |
| Partial Shipment Splits | 2–3 FCs | Reduced |
| Minimal Shipment Splits | 1 FC | Highest IPSF |
The seller picks; the IPSF is a per-unit charge added at receipt.
Indicative IPSF (US, standard size)
| Placement type | Standard-size unit | Large bulky |
|---|---|---|
| Optimised splits | $0.00 | $0.00 |
| Partial splits | $0.21–$0.30 | $1.30–$1.65 |
| Minimal splits (1 FC) | $0.27–$0.47 | $2.04–$3.50 |
For oversize, the per-unit IPSF can exceed the FBA fee. For standard-size, it is a small but persistent line item.
The trade-off
| Choice | Pro | Con |
|---|---|---|
| Optimised (free) | $0 IPSF | Multiple shipments, more pallets, more freight cost |
| Minimal (1 FC) | Single shipment, cheapest freight | Per-unit IPSF compounds across every unit |
For most mid-size sellers, optimised splits are cheaper end-to-end — the freight overhead of one extra pallet is less than the IPSF on the consolidated alternative. For tiny shipments (<100 units), the consolidated option can win.
Common mistakes
- Defaulting to minimal splits on autopilot. Adds 1.5–4% to landed cost on most orders.
- Not modelling IPSF into landed cost. Per-unit FBA cost analysis that ignores IPSF understates by $0.20–$0.50.
- Re-routing post-receipt. Once Amazon receives at fewer FCs, it does the redistribution work and bills you — there is no refund path.
- Treating IPSF as one-time. It applies to every inbound shipment, not once per SKU.
