FLEX. Logistics
We provide logistics services to online retailers in Europe: Amazon FBA prep, processing FBA removal orders, forwarding to Fulfillment Centers - both FBA and Vendor shipments.
Amazon closed its in-house FBA prep and labeling service in the US as of January 1, 2026. For brands that relied on that service to handle FNSKU labeling, polybagging, or bubble wrapping at the FC, the liability for compliant inventory now sits fully with the seller. Inventory that arrives without correct prep does not get quietly fixed anymore; it faces check-in rejection, delayed availability, or loss of reimbursement eligibility. This is not a policy footnote. It is a supply chain gap that affects every shipment scheduled for a US fulfillment center. The practical question for a brand manager is not whether prep matters, but who now owns it: the factory, a US-based prep vendor, or an Amazon seller prep service built specifically to absorb this handoff. The next 90 days decide whether that gap gets closed in a planned way or discovered at check-in.
What Amazon Actually Stopped Doing
Amazon's in-house prep service used to catch gaps before they became FC problems: a missing FNSKU label, a product needing suffocation warning bagging, a bundle that required extra packaging. Amazon would apply the fix, bill the seller, and let the unit continue into stock. That safety net is gone in the US as of January 1, 2026. Inbound inventory is now checked against Amazon's packaging and prep requirements without a fallback service to correct it on-site.
The mechanism that breaks first is receiving. A carton without correct FNSKU labeling or required polybagging is not simply flagged and passed through; it can be rejected at check-in, held pending correction, or returned at the seller's cost. Reimbursement claims for lost or damaged units also depend on documented compliant prep, so a labeling gap does not just delay a shipment. It can quietly remove a seller's ability to claim for that inventory later. Brands running thin margins per unit will feel this in claims data before they feel it in complaints.
What Must Be Confirmed Before Goods Move
Before any carton leaves the factory or a domestic 3PL, someone needs to confirm three things: which SKUs require FNSKU labeling versus which are enrolled in barcode transparency, which items trigger mandatory polybagging or suffocation warnings under current Amazon inbound packaging requirements, and which bundles need additional securing. This is not a one-time check. Amazon updates these requirements periodically, and a supplier packing list from six months ago is not a reliable source of truth today.
The audit should map every active ASIN against its current prep requirement, not assume last year's process still applies. If the factory has been applying prep without recent verification, that assumption is now a real exposure point rather than a convenience.
What Breaks When Responsibility Is Unclear
When no one owns the prep check explicitly, the failure shows up as a pattern: intermittent check-in rejections, unexplained inventory delays, and reimbursement claims that get denied for lack of prep documentation. None of these show up as a single dramatic event. They accumulate as friction, and by the time a brand manager notices the trend, several shipments are already affected.
The commercial cost is not just the rework. It is the FC availability window missed during a demand spike, and the customer-facing stockout that follows. A shipment stuck in a rework queue during Q4 does not just cost prep fees; it costs sellable days on the listing.
Factory Prep vs. 3PL Prep Hub: the Real Trade-off
Brands generally choose between two models now that Amazon's own prep option is gone: pushing prep back onto the factory, or routing inventory through a dedicated 3PL prep hub before it reaches the FC. Factory-level prep can work when the factory already has stable packaging lines and a low SKU count, but it depends on the factory staying current with Amazon's requirements, which most manufacturing partners are not set up to track closely.
A 3PL FBA compliance-focused prep hub sits between the factory and the FC specifically to catch what the factory misses: relabeling, polybagging, suffocation warning application, and bundle assembly, all inspected against the current requirement set before the carton is sealed for Amazon. This model adds a step in the chain, but it also adds a checkpoint. For brands managing multiple SKUs, private label lines, or seasonal bundles, that checkpoint is often the difference between a smooth check-in and a returned pallet. The trade-off is lead time versus risk exposure, and most brands scaling past a handful of SKUs land on the 3PL side once they've absorbed one rejected shipment.
30-Day Phase: Audit and Supplier Adjustment
- Pull the current Amazon inbound packaging requirement for every active ASIN, not a cached list.
- Identify SKUs needing FNSKU labeling versus those on barcode transparency.
- Flag items requiring suffocation warning bags or extra securing for bundles.
- Confirm with each factory or supplier whether their packaging line can meet the updated spec.
- Document gaps in writing rather than relying on verbal supplier confirmation.
60-Day Phase: 3PL Hub Onboarding and Pilot
- Select a prep hub with documented FNSKU labeling services and polybagging capability.
- Route one SKU family through as a pilot shipment before full volume commits.
- Check the pilot's FC check-in outcome, not just prep completion at the hub.
- Confirm carton labeling and pallet structure match Amazon's current inbound spec.
- Set a clear escalation contact for any rejected or held pilot units.
90-Day Phase: Full Operational Cutover
- Move all active SKUs onto the confirmed prep workflow, factory or hub.
- Retire any packaging process that has not been re-verified against current rules.
- Confirm reimbursement documentation is being generated at the prep step, not assumed.
- Set a recurring quarterly review of Amazon's inbound packaging requirements.
- Track check-in rejection rate as the primary compliance signal.
Ongoing Controls Once Cutover Is Complete
- Assign one internal owner for prep compliance, not a shared responsibility.
- Require prep confirmation before any carton is booked for FC forwarding.
- Keep a change log when Amazon updates FNSKU or bundling rules.
- Review reimbursement denial reasons monthly for prep-related patterns.
- Reassess factory-versus-hub allocation each time SKU count changes materially.
Sequencing the Decision: What to Lock First
The order of operations matters more than the individual tasks. Start with the audit, because prep decisions made before confirming current requirements just repeat the old assumption under a new label. Once the audit is complete, the factory-versus-hub decision becomes a capacity question rather than a guessing exercise: does the factory have proven, current packaging capability, or does the SKU mix and bundle complexity justify routing through a dedicated pre-FBA prep hub instead.
Brands selling into both the US and European FBA channels face a compounding version of this problem, since prep standards and FC receiving behavior are not identical across regions. A workflow built only around US requirements will not transfer cleanly to Amazon EU inbound, which is where a pan-EU prep and pre-Amazon storage partner becomes relevant for brands scaling across marketplaces rather than treating each region as a separate fire to put out. The sequencing discipline that works in the 30/60/90 window here is the same discipline that keeps a transatlantic operation from repeating this exact problem region by region.
Responsibility Owner
Assign one named person, not a team, to confirm prep compliance before any shipment books an FC appointment. Shared ownership is how gaps get missed between the factory email and the ops calendar.
Document Checkpoint
Every carton needs a paper trail: which prep spec it was checked against and when. Without this, a denied reimbursement claim has no supporting evidence to appeal.
Escalation Rule
If a shipment is held or rejected at check-in, route it to the prep hub or factory contact within 24 hours, not at the next scheduled review. Delay compounds storage cost and lost sellable days.
What to Decide Before the Next Shipment Books
The core decision is not whether prep matters now that Amazon has stepped back from it. It is whether your current supplier or in-house process can prove, shipment by shipment, that it meets today's requirement, not last year's. If that proof does not exist, the factory-only model is carrying more risk than most brands realize until a pallet gets held.
A 3PL FBA compliance hub does not remove the need for the audit; it gives the audit somewhere reliable to land. Brands running single-unit, bundled, or multi-marketplace SKUs generally get more consistent check-in outcomes once prep sits with a dedicated hub built around FNSKU labeling services and current Amazon inbound packaging requirements, rather than a factory managing it as a side task. Before your next shipment books an FC appointment, confirm which of the three phases above your operation is actually in, because the gap between where you think you are and where the packaging line actually is tends to surface at the worst possible time.
If your supplier packaging workflow has not been re-verified against current Amazon prep rules, or you are weighing factory-level prep against a dedicated hub, FLEX. can walk through the audit and pilot phases with you. Our pre-FBA prep and storage setup in Europe is built for brands managing this exact transition across transatlantic and EU FBA channels, and we can help you confirm whether your current process holds up before the next shipment books an FC appointment.
