Getting ready to sell your products on Amazon FBA is not a simple task of putting a label on a product and sending it to your buyer, but rather an elaborate procedure that can determine the success or failure of your seller. Over the years as an employee who has been two feet deep in supply chain logistics in BM Supply Chain, I have been able to witness sellers who have succeeded when they got this step right and those who have failed due to their failure to do so. When Amazon ceases to offer prep services in their FBA on January 1, 2026, it will be entirely up to you to either get it all right or outsource intelligently. Effective Amazon FBA inventory preparation will guarantee that your goods are received in the proper condition, ready to be efficiently processed, and have no quality flaws that may cause a product recall or account deduction.
Why does it matter? Get it wrong and you are facing rejections at the warehouse door, unsoftened preparation costs (which Amazon will no longer pay on behalf of) and time loss as stock is unavailable and the repetitive nature of the issues is even subject to suspension. On the other hand, by doing it right, there is faster turnaround, satisfied customers and improved margins. It simplifies to checking, labeling, filling, and strategizing your inbound shipment very carefully.
Simply put, to begin with quality verification at the origin, add the appropriate labels and protective measures, bundle when necessary, place into compatible cartons and create your shipment plan in Seller Central. Upstream management saves headaches when it comes to sellers sourcing in China, which is the case with the majority of sellers. It is time to get down to action now.
How to Prepare FBA Inventory
The process of FBA inventory preparation implies preparation of your goods to the rigorous standards of Amazon before they are deposited in the warehouse. This involves all the inspection in order to establish quality, labeling to track, secure packaging to avoid damage as well as carton set up to avoid receiving problems. Missing any part will incur fees, delays or even rejections, particularly after 2026 when Amazon ceases to provide prep help.
Proper preparation is essential since the system at Amazon is ruthless. One mislabeled box can delay all your shipments resulting to stockouts and missed sales. The old hands in the trade recognize that: We have assisted clients at BM Supply Chain save thousands of dollars in expenses by preparing in China, where they would cost less and this is easy to fix.
Summary: Look first, label correctly, wrap or polybag, fairly bundle, carton pack right, pallet big, devise listing and ship cleverly. To start with, here is a bullet-point preliminary shopping list:
- Review items: Quality, quantity and variants.
- Label with FNSKU: any manufacturer barcodes?
- Poly-bag needed products: 1.5 mil warning bags.
- Guard against it Delicate stuff: Bubble wrap or dunnage.
- Bundle sets: Label “Sold as Set.”
- Carton prep: Less than 50 lbs, named properly.
- Shipment plan: Add information in Seller Central.
- Ship: Select the approach to the time schedule.
Step 1: Inspect Products Before Sending to Amazon
The first defense is inspections. Why? Defects such as cracks, incomplete parts or wrong colors result in returns, which plunge your metrics. BM Supply Chain is a firm that will always suggest third-party checks where it is always better to identify the problems early before it is too late and spend on international shipping to correct the problems.
What to check:
- Number: Check counts are as per your order.
- Quality: Check some damage or stains or any fault made during manufacturing.
- Function: Check if there is such, such as electronics booting.
- Packaging: Supplier packaging should not be advertising in case it is limited.
- SKUs: Variants/Colors: No mix-ups.
Doing this in China vs. U.S./EU? Enormous benefits, such as access to cheaper labor, the ability to rework something fast, and same-day repairs. We have already checked thousands of deliveries, reducing the number of defects in clients by 80%.
Step 2: Apply FNSKU Labels Correctly
FNSKU labels are custom barcodes used by Amazon to keep track of your inventory- each of the sellable units requires one. Otherwise, or should it be lost, your shipment is bounced.
FBA labeling policy of Amazon: The labeling must be done on the biggest flat area and it cannot be folded or wrinkled and any existing barcodes should be covered so that scanning does not cause errors. In case your product contains any scannable manufacturer barcode then remove it or cover it fully.
One of the most popular rejection reasons is mislabeling- Amazon scans it all. Accuracy tips: Move away: Lablels will be strong and resistant to smug; print in Seller Central; place labels twice. Pro production: Expertly outsource to FBA fulfillment center in China to be accurate we have automated tools to achieve 99.9% accuracy.
Step 3: Use Poly Bags When Required
It is obligatory that Amazon FBA poly-bag for some items cannot be negotiated as it allows dangers and damage. Apply them on soft, dusty or liquid prone products.
Important regulations: Bags should be thicker than 1.5 mil of clear and sealable bags. In any opening that are more than 5 inches, put a warning in 20 point font: 20 point font: “WARNING: To prevent the risk of suffocation, keep this plastic bag out of the reach of babies and children.
What is needed: Clothing, plush toys, powders or any other item that can be dirtying to others. However, do not have sharp edges sticking out. This ensures that goods are not dusty when being transported to eliminate complaints.
Step 4: Bubble Wrap & Protective Packaging
Perishable goods require additional attention when creating an Amazon FBA package checklist. Bubble wrap or void fill will ensure that there is no breakage hence fewer returns and favorable reviews.
In the case of electronics: Wrap one by one, anti-static as required. Glass or cosmetics, Two-layer bubble, fastened in boxes. Why? Everything is jostled by transit, no protection is an arrestive.
Expert comment: Simulation of test packaging with a drop of 3 feet. We have even prepared delicate sets to our clients and the drop off has reduced to 5 percent to less than 1 percent.
Step 5: Bundle or Kit Products Properly
Bundling adds value but should be regulated. Gift sets or multipacks must be well packaged in a way that they will come as a complete package.
Instructions: On all sides write Sold as Set, or Do Not Separate. Shrink wrap or use clear tape – not something that harms things. Uninterrupted packaging means that they are not unpacked in Amazon.
E.g. charge phone case and charger- wrap, label. Loose bundles? They are separated and result in fees.
Step 6: Add Insert Cards & Branding (Optional but Recommended)
Branding can be achieved through inserts such as thank-you cards or manuals without breaking of rules. Keep them unpromotional, no outside-links or upsells.
Regulature: Do not have inserts that cause obscuring (of labels) or create hazards. Great for building loyalty. In BM Supply Chain, we insert custom inserts in the course of prep and we are assisting our clients to be noticed.
Step 7: Follow Amazon Carton Requirements
Carton requirements Amazon has in place make warehouses efficient. Maximum weight: 50 pounds per box (except single item above). Dimensions Longest side lengths less than 25 inches of some carriers.
Integrity Use boxes with doubling of walls sealed H-pattern. None of mixed SKUs except in a multi-box shipment. Seal securely—no loose flaps.
meshing Cannabox labels: include Amazon ship ment identification, Amazon FBA box number and Team Lift on body of heavy ones. This eliminates delays in processing.
Step 8: Prepare Pallets (If Required)
In the case of large loads (above 150 lbs LTL), pallets are required. Specification: Wood, 40 x 48 inches, heat-treated (ISPM-15).
Shipment details on all four sides. Stack, shrink- wrap, no overhang. Truckloads required- guarantee safe handling.
Step 9: Create an Amazon Inbound Shipment Correctly
On Seller Central, create your shipping plan: Choose the products, quantities, and warehouses. Key in carton size and weight.
Also create labels, post box contents data (SKUs in a box). Make reservations with partnering carriers at discount. This is in line with inbound shipment rules by Amazon, accelerated receipt.
Step 10: Choose a Shipping Method from China to Amazon
Sourcing from China? Choose carefully: Air (5-10 days, expensive when launching a product); sea (20-40 days, cheap when shipping a lot of products); express mailing companies (3-7 days, mid-priced); DDP (duties paid, hassle free).
Most suitable when using FBA: Sea in case of established lines, air in case of restocks. This is done by us at BM Supply Chain at the cost and speed optimization.
