Effective for shipments created on or after January 1, 2026, Amazon no longer prepares or labels your products inside its FBA warehouses. You handle prep yourself, or you use a third-party prep center. Six months in, the change stuck, the real enforcement turned out to be the inbound defect fee, and a second deadline (the March 31 commingling end) made FNSKU labeling near-universal for resellers. This page is the six-months-later report.
Per Supply Chain Dive's reporting on Amazon's seller announcement:
“The company said the change, which will take effect at the start of 2026, is due to improvements in sellers' packaging capabilities.”
Amazon's statement, in its own words:
“The vast majority of Amazon sellers now handle their own packaging, including prep and item labeling, either on their own, through their own manufacturing partners or through third-party service providers.”
Industry response has been direct. Charles Williams, senior manager of marketplace operations at the omnichannel agency Blue Wheel, called it “one of the most significant operational shifts Amazon has made in recent years.” Reddit's /r/FulfillmentByAmazon thread “So… Amazon just dropped FBA prep” ranks top-10 on the relevant SERPs.
The fulfillment centers themselves are unchanged. Only the inbound prep step moved out of Amazon. For the network you still ship inbound to, see our Amazon fulfillment center directory.
Amazon tells sellers by email that US FBA prep and item-labeling services will end. First trade-press coverage lands August 1 (Supply Chain Dive). Amazon does not pin a public announcement day, so neither do we.
The end date. No prep or labeling for shipments created on or after this date, across FBA, Amazon Warehousing and Distribution, Amazon Global Logistics, Amazon Send, and Supply Chain Portal. Shipments created before the date still got prepped even if they arrived later: the trigger is creation date, not arrival.
A separate squeeze begins: a bulky packaging fee (reported around $1.51 to $4.04 per unit, about $2.07 average) for Small and Large Bulky items not enrolled in Ships in Product Packaging.
Commingling ends. Brand Registry brand owners may switch to manufacturer barcodes; resellers must apply an FNSKU to every unit. Combined with the prep shutdown, labeling work became near-universal for arbitrage and wholesale sellers.
No walk-back, no extension, no reversal. A policy tracker updated July 11, 2026 records none, and every current industry source treats the change as permanent.
The story since January is not that a convenience disappeared. It is that the price of arriving non-compliant went from trivial to punitive. In 2025, the inbound defect fee ran roughly $0.02 to $0.07 per unit, and Amazon would quietly fix prep problems for a fee. In 2026 the reported defect-fee range is $0.32 to $5.72 per unit depending on the problem and size tier, with bulky items highest. Published figures conflict on the exact schedule (some sources describe a flat consolidated fee, others the full range), so treat these as industry-reported numbers and check Amazon's official 2026 fee schedule for your category. The magnitude is not in dispute: a labeling defect across a 500-unit shipment now costs on the order of $300 where it used to cost a few dollars.
And there is no fix-it-at-the-door option at any price. Non-compliant inventory is refused, returned at the seller's expense, or disposed of. Two things Amazon has told sellers directly in its own Seller Central forum: units damaged because they were improperly prepped “aren't eligible for reimbursements,” and if you use a third-party prep provider, “all contracts and transactions are managed between you and the service provider”: your prep partner's mistakes are your liability at receiving. That is exactly why the checklist below now asks whether a prep center will put defect-fee responsibility in writing.
No. Through July 2026 there has been no reversal, no extension, and no announced plan to restore in-house prep. Plan as if it is permanent, because every signal says it is.
Industry coverage agrees third-party prep absorbed significant volume in the first quarter, but nobody publishes a market-share number, so here is what we can measure first-hand. Our census tracks 715 prep-labeled operations (July 2026 count). Roughly half are general 3PLs wearing the prep label, about a fifth are dead, and 107 have cleared our 4-point verification and are published in the directory, up from 66 in early June. Across the hand-verified public rate cards in our 2026 Pricing Index, the median US entry price is $1.30 per unit, consistent with the $0.75 to $1.50 range industry sources quote for standard prep.
The churn number is the one sellers should sit with: about a fifth of the prep-center universe we track is dead. Operators enter and exit this market constantly, which is why every listing in our directory carries a last-verified date and why dead businesses get flagged instead of silently lingering. The full census, with the exact partition and a downloadable dataset, is at The State of FBA Prep 2026.
Most affected proportionally. In-house prep was a real cost cushion. Either accept ~$1–$2/unit on a third-party prep service or build a kitchen-table prep workflow at home. Many small sellers also qualify for Amazon's Ships in Product Packaging program for already-retail-ready items.
Sweet spot for third-party prep. Volume is enough to negotiate per-unit pricing under the listed rate. Multi-channel sellers should look at hybrid prep + 3PL providers; FBA-only sellers should look at pure FBA prep specialists for the per-unit pricing edge.
Likely already using third-party prep or your own warehouse. Amazon's in-house service rarely served your volume cleanly. Some large sellers will accelerate moving to full 3PL relationships now that the in-house option is closed.
Amazon's own seller guidance describes packaging, labeling, and inspection requirements per category. Workable if you have low SKU count, simple products, and physical space. Bottleneck risk on scale: once you're past 500–1,000 units/month, your time is worth more than the per-unit prep savings.
A small focused prep shop charges $1–$2 per unit for standard prep and handles inspection, labeling, polybag, kitting, and inbound FC routing. Most US prep centers turn shipments around in 24–72 hours. We maintain a verified directory: every published center cleared our 4-point operator standard before listing.
Eligible items shipped to Amazon FBA in their retail packaging can be exempted from many prep requirements. Eligibility depends on package durability, SKU labeling, and category. Best for items already manufactured retail-ready (consumer electronics, books, certain CPG). Since January 15, 2026 SIPP does double duty: certified items also avoid the new bulky packaging fee that hits non-certified Small and Large Bulky products.
The six questions a verified prep center should answer plainly:
Urva Prep Center is a multi-service Amazon FBA and Walmart WFS prep operation in tax-free Newark, Delaware, running a primary 25,000 sq ft facility at 301 Ruthar Drive plus a 10,000 sq ft site in Bear. FBA and WFS prep is the productized core, with wholesale prep from $1.00 down to $0.55/unit by volume and online-arbitrage prep from $1.50 down to $1.00/unit. Alongside prep it offers FBM and DTC order fulfillment (same-day before the 7am EST cutoff), two-step dropshipping, FTL inbound consolidation at $0.20 to $0.50/lb, shrink-wrap, and a software dashboard. Storage is free for 14 days then $0.01/unit/day. Hazmat is accepted. Because it runs fulfillment alongside prep, confirm scope directly if you want a prep-only relationship.
Delta Prep Solutions is a family-operated, home-based FBA prep service in Northern California. Prep runs in a dedicated climate-controlled structure of about 1,200 sq ft on the operators' residential property, with locked access and security cameras (operator-confirmed by email, 2026-08-15). The rate card is one of the more transparent we have reviewed: a flat $1.50 per unit covering FNSKU labeling, standard polybagging, expiration-date labeling, 2-3 item bundling, and a final quality check, with no order minimums and a stated 1-2 day turnaround. The stated specialty is online-arbitrage sellers shipping roughly 1,000-1,500 units per month, which fits the operation's scale. What a buyer should weigh: the business is young (operating since mid-2025 by domain evidence), we could not find customer reviews or any third-party footprint for it, and contact runs through a Gmail inbox and a single phone line. The website's warehouse imagery is stock photography, not the facility itself.
FBA Champs is a New Jersey prep center handling Amazon FBA inspection, FNSKU labeling, polybagging, bundling, bubble wrap, and box packing, located about 35 minutes from Amazon's ABE8 warehouse in Florence, NJ. Per-unit prep runs $0.45 to $1.00 by volume with no contract, no sign-up fee, and no minimums, and they accept new sellers with low quantities. They also offer FBM multi-channel pick-and-pack, FBA returns processing, box and pallet forwarding, and monthly storage; FBA prep is the core service and these are add-ons. Turnaround is stated at 24 to 72 hours.
Express Prep and Ship is a family-scale FBA prep operation in Columbus, Montana, a sales-tax-free state, operating since late 2022 (domain and site history) and registered as Express Prep And Ship LLC (Montana SoS C1405820, Active-Good Standing, agent Sandra June Croft, registered December 2023). The card is published and per-unit: $1.25 per unit received, including inspection, label removal, damage photos, and FNSKU, fragile, and suffocation labeling; books $2.00 with poly bag; shoes $2.50; oversize $4.00; bundles $1.25 per item for the first two items, $1.00 at three or more. A $50 one-time registration fee applies, with billing on the 1st and 15th. Onboarding runs through Seller Central user permissions (Inventory and Shipments). Cautions, plainly: the ship-to address sellers are given is a residential property with no outbuildings on record, and the state registry lists no principal business address at all (mailing address only), so where the work physically happens is unconfirmed (the common Montana cottage-operator pattern), the published phone is a personal mobile line, the signup page shows two different Gmail addresses (the homepage address is canonical), and third-party reviews are absent beyond one dated on-site testimonial.
Express Prep Center is a New Jersey Amazon FBA prep service in Pennsauken. Per-unit prep runs $0.65 to $0.85 per unit by volume and covers receiving, exterior inspection, FNSKU labeling, poly bagging, dunnage, barcode removal, and ship-to-Amazon in 24 to 48 hours, with 14 days of free storage included. It also offers FBA returns processing, longer-term storage ($15/box or $50/pallet per month), and freight forwarding with optional inspection. Domain registered May 2024; listed as accepting new clients.
