What the Fba Checklist Top 10 Actually Looks Like in Practice
I used to skip most of this stuff. That was before my first three shipments got rejected at an FBA warehouse and I had to repack everything over a weekend just to keep inventory flowing. Now I go through the list religiously. Here is what actually matters. 1. Verify your product labels match exactly what Amazon expects. Each unit needs a scannable FNSKU barcode. Some people slap the manufacturer barcode on there because it looks cleaner. Do not do that. Amazon scans what you tell them it is. If the label does not match the SKU in your shipment plan, it gets flagged. 2. Confirm your prep requirements before you pack a single box. Some products need polybagging. Some need bubble wrap. Some need both. Amazon has a prep requirements page for every SKU. Check it. I once sent a six-pack of glass candles without bubble wrap because I assumed Amazon would handle it. They did not. Every one cracked, and I paid the return disposal fee.
3. Weight and dimensions must be accurate, not estimated. Weigh each box on a calibrated scale. Measure length, width, and height with a tape measure, not by eyeballing it. If you underestimate, Amazon will re-weigh and re-measure everything, apply their fees, and charge you the difference. It adds up fast across hundreds of units. 4. Box weight should stay between 25 pounds and 50 pounds per side. Amazon has a 50-pound limit per box for single-box shipments, and for team lifts it is higher but you need special labeling. I learned this when a box of dense ceramic mugs hit 62 pounds. The receiving clerk made me reopen and redistribute two dozen units across extra boxes. 5. Use the right box size. Amazon charges for dimensional weight. A 12x12x12 box full of small items costs more to store and fulfill than it should. Downsize or right-size. I switched from using 16-inch boxes for medium products to 14-inch boxes and cut my storage fees by roughly 11 percent across the board. Small savings that compound over quarters.
6. Ship-to facility codes matter more than most sellers realize. Not all Amazon fulfillment centers are equal. Some are near your suppliers and cheaper to send to. Others handle your category better and restock faster. Run a quick cost comparison between two nearby FCs using Amazon's in-route tool. Sending to the wrong one once cost me an extra three days and $400 in inbound shipping. 7. Case pack quantities must be consistent inside each box. If you are case packing, every box of the same SKU needs the exact same count. Mixed case packs require special handling and often get stuck in Amazon's review queue. I once accidentally shipped a box with 12 units instead of the standard 24. Amazon held the entire shipment for 11 days while they verified the case pack. 8. Tracking numbers need to be uploaded before the shipment deadline. Amazon requires valid tracking for every box in your shipment plan. Missing or invalid tracking pushes your shipment into a delayed state and can trigger a late delivery flag on your account. Double-check tracking before closing the shipment.

9. Pallet standards are strict if you are shipping freight. Pallets must be 48x40 inches, non-overhanging, stackable, and properly wrapped. You cannot use heterogenous pallets with multiple SKUs unless they are labeled correctly. I had a pallet rejected because I used 48x48 sheets that were slightly warped. The receiving dock would not accept them. I drove it back, restacked, and reshipped at my own cost. 10. Keep your shipment creation and labeling order correct. Create the shipment plan first, then print labels, then apply them, then box, then weigh, then close the shipment. The order matters because some label types change based on box weight and dimensions entered during creation. I reversed the order once and ended up with 80 mismatched labels that needed reprinting. One edge case that catches people: products with variants. If you have the same product in different colors or sizes, each variant needs its own FNSKU. They share the same parent ASIN but Amazon treats them as separate SKUs in the warehouse. I merged two color variants into one box by mistake and Amazon split them on arrival, adding two days of processing time and a small reconciliation fee. Always keep variants separated in your packing plan.
The biggest downside to this whole process is that Amazon changes their requirements periodically without much notice. Last year they changed their expiry date labeling rule for food and consumables. Shoppers who had already labeled according to the old rule had to relabel hundreds of units before shipping. There is no perfect workaround other than checking Amazon's seller help pages every month or two. If you want a downloadable version, Amazon's Seller Central has a built-in Fulfillment by Amazon Shipment Settings page where you can export your shipment details. Third-party tools like Helium 10 or Jungle Scout also offer checklist overlays that sync with your Seller Central account and flag incomplete steps before you submit. Those save maybe 20 to 30 minutes per shipment cycle depending on how complex your catalog is.
