This Amazon FBA product research checklist runs in a deliberate order, and the order is the point. Disqualify first, then measure, then sample. Most beginners do it backwards: they fall for a product, calculate how good it could be, and only discover the gating problem or the battery rule after the money is committed.
I’d work down the list in order. Anything that fails a stage stops there, and you have saved yourself the next stage.
Stage 1: the five disqualifiers
Ten minutes each, and in my experience most candidates die here. Any single failure ends it, regardless of how good the numbers look.
- [ ] Is the category or brand gated? Search the product in Add a Product in Seller Central and look for a “Request approval” link. If it is brand-gated, walk away. Category gating is workable but adds weeks and an invoice requirement.
- [ ] Does it contain a lithium battery, liquid, aerosol, or anything flammable? All of these trigger hazmat review, which adds time and restricts your fulfillment options.
- [ ] Is it ingestible, applied to skin, or used by infants? Compliance and liability that a first product should not carry.
- [ ] Is it oversize or over about 3lb? Fees scale hard, and margins that work on a light item disappear on a heavy one.
- [ ] Is it electrical, or does it carry a safety certification requirement? Real compliance costs. Our guide to selling electronics on Amazon covers what that involves.
Two more that are not absolute but should make you pause. Seasonal-only demand, because you get one selling window a year to learn in. And anything where a single brand owns the search term, because that category is not really contestable.
I’d run this stage on twenty candidates before running stage two on any of them. It is fast, and it kills most of the list.
Stage 2: the demand and competition numbers
Now measure what survived, and I’d do it in this order too.
- [ ] Monthly search volume on the main keyword. Between roughly 3,000 and 30,000 is the useful band for a first product. Below that the market may not exist. Above it, page one is usually defended by budgets you cannot match.
- [ ] Lowest review count on page one. Under 150 is reachable within months. Over 2,000 is not.
- [ ] Lowest star rating on page one. Anything under 4.2 is an opening, because a weak rating means a fixable product problem.
- [ ] Brand concentration. If one brand holds more than about 40% of page one, someone is defending it.
- [ ] Listing quality of the top three. Amateur images and copy on page one mean those rankings came from age rather than effort.
- [ ] Price band. Between $20 and $60 is easiest. Below $20 the fees eat you; above $60 buyers deliberate and conversion falls.
- [ ] Number of competing listings. Fewer than eight is a warning, not an opportunity. Almost no competition usually means almost no demand.
The screening logic behind these thresholds, and why the rating signal matters more than the rest, is set out in our guide to finding low competition products. This checklist gives you the sequence; that page explains the reasoning.
Stage 3: the arithmetic
Do this on paper before you contact a single supplier. I’ve found sellers who skip straight to sourcing end up justifying a number rather than testing one.
Take the retail price you expect to hold. Subtract the Amazon referral fee, usually 15%. Subtract the FBA fulfillment fee for your size and weight band, which you can look up rather than estimate. Subtract your landed unit cost, meaning the product plus freight plus duty, not the factory quote. What is left is your contribution per unit.
Then subtract advertising. A new product usually needs to buy a meaningful share of its early sales, and I’d model 20 to 30% of revenue going to ads in the first months rather than the 10% a mature listing runs at.
- [ ] Contribution per unit after all fees and ads is at least $5. Below that, ordinary variance in fees or returns wipes it out.
- [ ] Margin after everything is 20% or better. Thinner than that leaves nothing for the mistakes you will make.
- [ ] You have modeled it at a pessimistic conversion rate. If it only works at 15% conversion and a premium price, it does not work.
That last checkbox is the one I’d defend hardest. In our experience the launches that lose money are almost always the ones that were only viable under optimistic assumptions, and optimism is not a business input.
Stage 4: capital and timing
The stage almost every beginner skips, and in our experience the one that causes the most damage.
- [ ] Total cash required, including samples, inventory, shipping, photography and launch advertising. Not just the inventory.
- [ ] Days from payment to first revenue. Production 30 to 60 days, freight 30 to 45, launch several weeks. Ninety to a hundred and fifty days is normal.
- [ ] You can survive that gap without this money. If you need it back sooner, this is the wrong model.
- [ ] You can fund a second order before the first sells out. Running out of stock mid-launch resets your ranking, and re-earning it costs more than the inventory would have.
I’ve found the reorder point is where first-time sellers most often come unstuck. The product works, they sell through, and the restock arrives six weeks after they went out of stock. By then the ranking has decayed and the launch has to happen twice.
Stage 5: samples
Only now do you spend money, and only a little. I’d keep this stage under a few hundred dollars.
- [ ] Samples ordered from at least three suppliers. A single sample tells you nothing about whether the quality is normal or lucky.
- [ ] Each sample checked against the specific complaint you found in competitor reviews. That complaint is your reason for entering; if your sample shares it, you have no product.
- [ ] Packaging and shipping durability tested. Ship one to yourself.
- [ ] Compliance documents requested where relevant. If a supplier cannot produce them, that is the answer.
- [ ] Minimum order quantity negotiated. The first number quoted is rarely the floor.

What I’d tell a beginner who has already picked a product
Most people find this checklist after they have fallen for something, not before. If that is you, the honest advice is different.
Do not start at stage one hoping it passes. Start at the arithmetic in stage three, using pessimistic numbers, because that is the stage most likely to kill the idea and you may as well find out in ten minutes. If the contribution per unit does not clear $5 at a realistic conversion rate, nothing in the earlier stages will save it and you have saved yourself a week.
If it survives that, then go back and run the disqualifiers, and run them honestly rather than looking for reasons to proceed. I’ve found this is genuinely hard when you are already attached to a product, and it is the main reason I’d rather people screen twenty candidates than evaluate one. Twenty candidates makes the decision comparative. One candidate makes it emotional.
The other thing worth saying: rejecting a product is a successful outcome, not a failed one. The purpose of research is to avoid committing capital to something that will not work, so a checklist that eliminates nineteen of twenty candidates is doing its job. In our experience beginners treat elimination as wasted effort and keep going on a marginal product because they have invested time in it. That is the sunk cost fallacy with inventory attached, and it is expensive.
One last note on tools. You can run every stage of this checklist without paying for software, using Amazon’s own search, the Add a Product page, the fee schedule and a spreadsheet. Paid tools make stage two faster and add nothing to the other four. I’d only buy one once the process is already a habit.
The order matters more than the items
If you take one thing from this Amazon FBA product research checklist, take the sequence rather than the boxes.
Every stage is cheaper than the one after it. Stage one costs minutes, stage five costs hundreds of dollars, and a full order costs thousands. Running them in order means the expensive checks only ever happen on products that already survived the cheap ones. Running them out of order is how people end up with a warehouse full of a product they cannot list.
Keep a record of what you rejected and why, with the date. Categories change, incumbents quit, patents lapse. In my experience a dated list of near-misses becomes more valuable than a fresh list of ideas, and it costs nothing to maintain.
FAQ
What should an Amazon FBA product research checklist cover?
Five stages in order: disqualifiers such as gating, batteries and oversize; demand and competition numbers; the fee and margin arithmetic; capital and timing; then samples. Each stage costs more than the last, so running them in sequence keeps expensive checks off products that were never viable.
What should I check first when researching an FBA product?
Gating and brand restrictions, because no amount of good margin survives being unable to list. Then batteries and hazardous materials, ingestibles and infant products, oversize or heavy items, and anything needing safety certification. These are pass-or-fail and take minutes to check.
What margin do I need for an Amazon FBA product?
At least $5 contribution per unit and 20% margin after the referral fee, FBA fulfillment fee, landed cost and advertising. Model advertising at 20 to 30% of revenue for a new product rather than the lower figure a mature listing runs at.
How much search volume should a first FBA product have?
Roughly 3,000 to 30,000 monthly searches on the main keyword. Below that the market may be too small to absorb a minimum order quantity; above it, page one is usually held by advertising budgets a new seller cannot match.
How long before an FBA product starts earning?
Ninety to a hundred and fifty days from payment is normal, covering 30 to 60 days production, 30 to 45 days freight, and several weeks of launch. Plan for the gap and make sure you can fund a reorder before the first shipment sells out.
How many supplier samples should I order?
At least three, from different suppliers. One sample cannot tell you whether the quality is typical or a good batch. Check each against the specific complaint you found in competitor reviews, since that complaint is the reason you are entering the category.
Last updated: September 10, 2026. Amazon referral and FBA fulfillment fees, size tiers, and gating rules change, so look up current figures in Seller Central and against Amazon’s seller documentation rather than relying on the bands here.
