How to Start an Amazon FBA Business with Liquidation & Surplus Inventory
Sourcing, prepping, and shipping liquidation and surplus goods into Amazon FBA — including which lots qualify, what gets rejected, and how to model fees before you buy.
Key takeaways
- · FBA rewards new, sealed, and shelf-pull inventory far more than raw customer returns.
- · Model referral fees, fulfillment fees, and monthly storage before you commit to a lot.
- · Gated brands and categories are the most common reason a profitable-looking pallet stalls.
- · Buy narrow and deep: one strong ASIN in quantity outperforms a mixed pallet of singles.
Decide whether FBA is the right channel for the lot
Amazon FBA is a condition-sensitive channel. New, factory-sealed overstock and clean shelf pulls move through it easily. Raw, untested customer returns rarely do — they require testing, repackaging, and often a used-condition listing that FBA restricts for many categories.
Before buying a pallet for FBA, ask a simple question: can every unit be listed as New, or do I have a legitimate used-condition path for it? If the answer is unclear, the lot belongs on a marketplace where you control the condition description.
Understand gating before you buy, not after
Many brands and categories require approval before you can list. Grocery, topicals, automotive, and a long list of individual brands are commonly restricted. Approval usually requires invoices from a supplier that Amazon accepts, and liquidation invoices are not always sufficient.
Check gating on the specific ASINs in the manifest while the lot is still available. A pallet of great product you cannot list is a total loss of working capital until you find another channel.
Model the fee stack honestly
The three recurring FBA costs are the referral fee (a percentage of sale price, commonly 8-15% depending on category), the fulfillment fee (driven by size tier and weight), and monthly storage (charged by cubic foot, rising sharply in Q4).
Add inbound freight from your facility to the fulfillment center, your prep labor, and an allowance for returns. Products under roughly $15 retail rarely survive that stack unless they are small, light, and fast-moving.
Prep requirements that cause rejections
Poly-bagged items need a suffocation warning on bags with a 5-inch opening or larger. Sets must be labeled as sets so they are not separated. Liquids and powders may require double-bagging. Sharp items need protective packaging. Every unit needs a scannable FNSKU label placed over the original barcode.
Remove or cover retailer stickers and clearance tags. Inbound shipments arriving with retail markings are a frequent source of buyer complaints and condition claims.
Choosing lots that suit FBA economics
Single-SKU or single-category lots are worth a premium for FBA sellers. They compress prep labor, produce one inbound shipment plan, and let you build real depth on an ASIN rather than a scattering of one-offs.
Small appliances, tools, home goods, and sealed consumables from overstock and shelf-pull grades are typically the most FBA-friendly liquidation categories. Mixed general-merchandise returns are typically the least.
Your first 90 days
Start with one pallet, not a truckload. Track actual time spent on unloading, sorting, prepping, and labeling, and convert it to an hourly cost. Track actual sell-through by week, not by hope.
After three lots you will have real numbers for your own operation: units salable per pallet, prep minutes per unit, and days to sell. Those numbers, not estimated retail value, tell you what to pay for the next lot.
Frequently asked questions
+Can I send liquidation customer returns into FBA as New?
No. An item can only be listed as New if it is unused and in original, sealed packaging. Opened or used returns must be listed under an appropriate used condition, and many categories restrict used listings entirely.
+Will Amazon accept a liquidation invoice for ungating?
Sometimes, but not reliably. Approval requirements vary by brand and category, and a liquidation invoice does not establish an authorized distribution relationship. Verify gating before purchase rather than assuming.
+What condition grades work best for FBA?
Overstock and shelf pulls, because units are typically unused and often still sealed. Salvage and raw returns are the weakest fit.
+How much should freight be as a share of the lot price?
Most buyers aim to keep freight under roughly 25-35% of the lot price. Beyond that, the per-unit landed cost usually erodes FBA margins to the point where another channel is more sensible.
+Do I need a resale certificate?
You need one to purchase for resale without paying sales tax in most states, and many suppliers require it before selling to you at all. Requirements are set by each state's revenue department.
