For about 1.1 million Amazon sellers in the US, January 1, 2026 closed the door on a service they had taken for granted: FBA prep. FNSKU labeling, poly bagging, bubble wrapping, suffocation warning labels. Amazon's announcement, dated July 28, 2025, gave the market five months to rebuild a function that used to come bundled with the fulfillment fee. US FBA inbound policy has shifted from “drop it off and forget it” to active supply chain management, with the cost of getting it wrong now landing in the seller's account, not Amazon's.
Importers feel it too. Amazon Global Logistics, AWD, and SEND used to fold prep into the inbound flow. That bundle is gone. Sellers now coordinate freight, customs, and prep separately, juggling three providers, three invoices, and three different levels of transparency. Freight exchange interfaces are gaining traction precisely for this reason. Through a reverse auction, carriers bid on inbound shipments, and the seller sees landed cost before the container leaves Asia. Carriers on the platform deliver and AiDeliv stays an interface for market-driven rates.
Who took the biggest hit
Small and mid-size sellers shipping 100 to 500 units per month carry most of the weight. A Distribution Alternatives survey from September 2025 found 64% of sellers expecting major operational impact. The pressure shows up in another number: 165,000 new sellers registered in 2025, the lowest count in a decade and a 44% drop from 2024. FBA compliance now demands real operational infrastructure from day one, covering everything from FNSKU labeling to poly-bagging requirements and suffocation warning labels.
Model | Per-unit cost | Best for | Compliance error rate |
Old Amazon FBA Prep (pre-Jan 1, 2026) | $0.55 to $1.50 | all sellers | ~1% |
3PL prep center | $0.40 to $1.50 (volume-dependent) | 200+ units/month | ~1% |
DIY (self-prep) | $1.20 to $1.80 (with labor) | <200 units/month | ~15% |
Inbound Defect Fee | $0.60 per defective unit | non-compliance penalty | n/a |
DIY looks cheap on paper. Run the math with 10 hours of labor per week at $25 an hour plus a 15% compliance error rate, and the Inbound Defect Fee swallows the savings.
“This is one of the most significant operational shifts Amazon has made in recent years. Getting ahead of it now will be key to maintaining smooth replenishment and avoiding compliance issues next year,” Charles Williams of Blue Wheel told Supply Chain Dive in August 2025.
What's actually ending and what penalties replaced it
Amazon labeling policy 2026 ended every prep service offered through the US marketplace: FNSKU labeling, poly bagging, bubble wrapping, carton prep, kitting, double-boxing for fragile items, and suffocation warning labels on poly bags. Before the shutdown, Amazon charged $0.55 per FNSKU label, $0.70 for basic poly-bagging, and $0.80 to $1.50 for bubble wrapping. The fees crept up in February 2025 ahead of the final wind-down.
Replacing those old fees is a single, blunt penalty: the Inbound Defect Fee at $0.60 per unit. For certain non-compliance categories, the financial impact runs 10 to 80 times higher than before. A 500-unit shipment with a labeling defect now costs $300 in penalties alone. Suffocation warning labels on apparel and plush items are entirely the seller's job. Even at the API level, AMAZON is no longer accepted as a value for prepOwner or labelOwner. The optional handoff to Amazon is technically closed.
3PL prep centers as the new standard
The 3PL prep center is now the default channel for seller-sent shipments. AMZ Prep starts at $0.40 per unit for high-volume sellers (2,500-plus units per month) and bundles receiving, labeling, and poly bagging. Pattern brings proprietary warehouse tech with transparent pricing. ShipBob covers the SMB end with multi-channel fulfillment across Amazon, Walmart WFS, and Shopify from one location.
What sellers are actually buying from 3PL prep centers in 2026:
Receiving and QC for inbound containers and domestic LTL deliveries
FNSKU labeling at item level and carton level
Poly bagging, bubble wrapping, and specialty packaging for fragile or oversized SKUs
Suffocation warning labels for apparel, plush toys, and textiles
Kitting and bundling for multi-pack and subscription SKUs
Multi-channel fulfillment that layers on top of Amazon FBA
Outsourcing is not the only path. Sellers increasingly push prep upstream, asking their manufacturer in China or Vietnam to apply FNSKU at the time of packing for $0.05 to $0.15 per unit, well below the $0.40 to $0.70 charged by US prep centers. The SIPP program (Ships in Product Packaging) shaves another $0.04 to $1.32 per unit. A hybrid model has also become the norm for merchants between 200 and 1,000 units per month: DIY on simple SKUs, 3PL on the complex ones.
What ending prep means for inbound freight
For importers, the end of prep services rewrote the path from factory to Amazon shelf. The AGL to AWD to FBA stack used to be a single track with prep already baked in. Today's chain has four independent links: international freight forwarder, customs broker, 3PL prep center, and the final hop into an Amazon FC. Landed cost transparency stops being a nice-to-have. It becomes a planning input.
Two choke points dominate this architecture. The first sits on the Asia-to-US port leg of freight forwarding. Rates run opaque, spot prices swing week to week, and DDP terms require duty math finalized before the container loads. The second sits between the port and the 3PL prep center. A seller needs either direct drayage from LA, Long Beach, Newark, or Savannah to the prep warehouse or shipment aggregation with other cargo to bring per-unit costs down.
Reverse auction platforms address that first choke point directly. A shipper posts a request for an inbound container or an LTL load on a freight exchange interface, carriers bid, and the seller picks a market rate with transparent DDP math. The interface only provides the comparison engine. Shipment aggregation at the platform layer pushes per-unit costs lower for sellers moving less than a full container.
“For millions of FBA sellers,'What do I do next?' is suddenly a front and center question. Disruption always brings opportunity. Sellers who take proactive steps now to adapt to Amazon's prep service changes will be best placed to thrive in 2026 and beyond,” Rob Hahn, Chief Operations Officer at Pattern, wrote on the Pattern blog in August 2025.
Four months into the new model, the picture is clear. 3PL prep centers are running at capacity. DIY survives only at the small end. The combination of a 3PL prep center plus transparent inbound freight is now the operating standard for any serious Amazon business. Amazon FBA prep services left behind a fragmented ecosystem, but a more competitive one.
