Shipments don't fail at Amazon for mysterious reasons — they fail because one of seven checkpoint groups got skipped: receiving verification, plan settings, labeling, packaging triggers, box content, carton specs, or pallet standards. This page is the working checklist itself, organized the way our warehouse actually runs it. Use it on your own shipments — or hand it to us and we run it on every one.
Aviation figured this out decades ago: competent people forget steps under time pressure, so the fix is a list, not more competence. FBA prep has the same shape. None of the individual checks are hard; what bites sellers is the one skipped item on shipment forty-three, discovered three weeks later as a problem flag or a stranded batch.
Order matters more than most guides admit. Labeling wrong goods wastes the labels. Perfect cartons full of unbagged liquids fail anyway. And since January 2026 there is no recovery lane at the far end — Amazon no longer preps or labels in the US, and unprepped inventory that's damaged or lost is outside reimbursement. The checklist is the safety net now.
One deliberate omission: this page names no specific size or weight numbers. Amazon publishes its current carton, pallet and prep requirements in Seller Central and revises them; a checklist with stale numbers is worse than one that says 'check the live limit.' Ours says exactly that, at every point where a number lives.
The table below is the compressed version — screenshot it. The sections after expand each group into the checks our own floor runs.
| # | Checkpoint group | Pass condition |
|---|---|---|
| 1 | Receiving verification | Counted vs. PO, condition photographed, correct goods confirmed |
| 2 | Plan & ownership settings | Prep and labeling owner = seller; plan matches physical shipment |
| 3 | FNSKU labeling | Right code per variant, flat placement, every label scan-verified |
| 4 | Packaging triggers | Bags, warnings, bubble, bundles, expiration labels per SKU attributes |
| 5 | Box content data | Generated from the pack-out itself, spot-audited before sealing day ends |
| 6 | Carton compliance | Within Amazon's current caps, sound corrugate, old barcodes covered |
| 7 | Pallet standards | Built, wrapped and labeled to Amazon's current freight requirements |
The compressed table gets you oriented; these are the checks inside the checks.
Count against the PO, photograph condition, confirm variant and packaging version match the listing. Prep starts only after the goods prove they're the right goods.
Prep owner and label owner set to seller on every SKU — non-negotiable since Amazon exited US prep in 2026 — and plan quantities reconciled against what's physically on the bench.
Correct FNSKU per variant, manufacturer barcode covered, flat placement off seams, and a confirmation scan on each unit. Sampling is how variant swaps escape.
Walk each SKU's attributes against Amazon's current prep requirements: exposed → bag with warning; fragile → cushion; liquid → seal; set → bundle as one; dated → expiration label.
Record contents while packing, from what physically went in. Spot-audit a sealed carton against its data before the shipment closes. Never retype from the plan.
Cartons inside Amazon's current dimensional and weight caps with clean exteriors; freight palletized, wrapped and labeled to the current standards — checked against the live rules, not last year's notes.
Run all seven groups on your next shipment, in order, checking Amazon's live requirements wherever a number is needed. Budget real hours the first time.
Your supplier ships to our Medley, FL dock; the checklist stops being your task list and becomes our standard procedure.
PO-verified receiving, settings reconciliation, scan-verified labels, trigger-mapped packaging, pack-out box content, compliant cartons and pallets.
The checked shipment hands to the carrier within 24–48 hours of receipt — and the next one runs the identical procedure.
Group 1 skipped. Receiving verification exists precisely so labor never lands on the wrong goods — a ten-minute count-and-compare would have stopped 800 units of rework.
Group 2 skipped. Physical perfection under a wrong shipping plan still jams at check-in — since 2026 there's no Amazon-side labeling to fall back on. The settings check takes two minutes and saves the shipment.
Group 3 done halfway. Sampling catches print problems; it structurally cannot catch the box of size-M units wearing size-L labels. Per-unit scan verification can, which is why we do it.
Group 7 skipped. Pallet standards feel like trivia until a fulfillment center door closes on them. We build freight to Amazon's current spec so the door opens once, in the right direction.
Seven checkpoint groups: received inventory verified against your PO, prep and labeling ownership set correctly in Seller Central, an FNSKU labeling pass with scan verification, packaging triggers mapped per SKU (bags, bubble, bundles, expiration dates), box content data generated from the physical pack-out, cartons within Amazon's current size and weight rules, and — for freight shipments — pallets built to Amazon's standards. Miss any group and the others can't save the shipment.
Count the units against the purchase order, inspect condition with photos, and confirm the goods match the listing — right variant, right color, right packaging version. Prep applied to short-shipped, damaged or wrong goods is wasted money, and supplier claims get harder every day after delivery. This is why our receiving step always runs before our prep bench touches anything.
That prep and labeling ownership are set to seller for every SKU in the shipping plan — mandatory since Amazon discontinued its US prep and labeling services on January 1, 2026 — and that the plan's SKUs, quantities and prep categories match what will physically ship. A perfect physical prep job under a wrong plan still produces a problem shipment.
Every unit carries the correct FNSKU for its exact variant; the label covers or supersedes the manufacturer barcode so only one code scans; placement is flat, not over seams or curves; print quality survives handling; and each label is scan-verified after application. Variant mix-ups deserve special paranoia — size 'M' labels on size 'L' units pass every visual check and fail every customer.
Product attributes that obligate specific prep under Amazon's current requirements: exposed or loose product triggers poly bagging with suffocation warnings, fragile items trigger cushioning, liquids trigger sealed bagging, multi-piece sets trigger bundling as one unit, and dated goods trigger expiration labeling. The checklist question per SKU is 'which attributes does this product have, and is the matching prep applied?' — not 'does this look fine?'
The reliable method is procedural: record contents as each carton is packed, from what actually went in, and never retype data from the shipping plan afterward. Then spot-audit — open a sealed carton and compare against its declared contents. If your packer and your data-entry person are different people working at different times, you have found your mismatch factory.
Cartons within Amazon's current dimensional and weight limits, sturdy corrugate that survives stacking, no repurposed retail boxes with old barcodes uncovered, correct shipment labels on the outside, and no mixed-SKU cartons unless the plan declares them. Amazon publishes exact caps in Seller Central and revises them — check the live numbers rather than memory when building anything near the limit.
Amazon's current inbound freight standards cover pallet type and condition, stack height, overhang (none), stretch wrap, and pallet labels placed where dock workers can scan them. LTL and FTL appointments also require accurate shipment data ahead of arrival. Freight refused at the fulfillment center door costs you the round trip plus the delay — pallet compliance is cheap by comparison.
For a seller doing it manually the first time, hours — mostly spent looking up Amazon's current requirements per SKU. For an operation that runs it daily, it disappears into the workflow: our receiving, labeling, packing and pallet steps each carry their checklist items, so a compliant shipment is the output of the process rather than an inspection after it. Turnaround at our warehouse stays 24–48 hours, checklist included.
That is effectively what our service is. Every shipment through our Medley, FL warehouse gets the full sequence — PO-verified receiving with photos, settings sanity check against your plan, scan-verified labeling, trigger-mapped packaging, pack-out-generated box content, compliant cartons and pallets. Send the form with your product mix and you'll have a per-unit rate sheet within one business day. No setup fees, no minimums.
Keep this page bookmarked for your own shipments — or send us your product mix and volume, and the entire checklist becomes standard procedure on every shipment through our dock. Per-unit rate sheet within one business day, no setup fees, no minimums.
