You can pick the right product on Alibaba, vet the supplier properly, negotiate a unit price you are happy with, and still lose money on Amazon. The quote you agreed to is only the first line of the cost stack: freight, import duty, Amazon's referral cut, the fulfillment fee, and storage all land on top of it, and most sourcing guides stop before anyone adds them up. So this guide walks the sourcing process in order and then does the arithmetic, which gives you two numbers before you commit any cash: what a unit costs you landed in a US fulfillment center, and what is left when it sells at your target price.
Alibaba is a wholesale platform that connects buyers with manufacturers, suppliers, and wholesalers across most consumer categories, from electronics and apparel to home goods and everyday household products. Prices are quoted by the unit, they move with order quantity, and every listing carries a minimum order quantity (MOQ) the supplier sets. Treat both the price and the MOQ as opening positions.
If you have not settled on Alibaba yet, our rundown of global alternatives to Alibaba for sourcing compares the other major platforms, and our overview of sourcing strategies for Amazon selling covers wholesale, private label, arbitrage, and the rest of the models you could be running instead. Everything below assumes you have chosen Alibaba and are working an actual order.
Six steps, in this order. The expensive mistakes almost all come from running them out of sequence, usually by wiring a deposit before the sample has arrived or before the shipping terms are settled.
1. Search and shortlist. Search your product, filter by the MOQ you can afford, and contact five to ten suppliers before you choose one. Quotes for the same written specification vary more than most first-time buyers expect, and a shortlist that size gives you a real price range instead of one number with nothing to compare it against.
2. Vet before you spend. For each supplier on the shortlist, check the verification status on the listing (the Gold Supplier badge and Alibaba's verified-supplier program), whether they accept Trade Assurance, their transaction history on the platform, and how quickly and how precisely they answer questions. A supplier who will not answer a direct question about materials or tolerances in writing does not get better after your deposit clears.
3. Order samples. Order from your top two or three, pay for them yourself, and test each one the way a customer will actually use it. This is also where you check that the packaging survives shipping and that what arrives matches the listing photos, because the sample is the only look you get at the real product before you commit to a production run.
4. Negotiate unit price and MOQ together. The two trade against each other: a larger order buys a lower unit price, and a smaller first run usually carries a premium. Get the final quote in writing with the specification attached to it, including materials, dimensions, packaging, and labeling, so there is a document to hold the production run against.
5. Settle the Incoterms before you pay. An FOB quote covers the goods delivered to the port of origin, which leaves you to arrange and pay for freight, insurance, customs entry, duty, and the inland leg to the fulfillment center. A door-to-door or delivered-duty-paid quote folds all of that into one number your supplier or their forwarder owns. Neither one is automatically cheaper, and comparing an FOB quote from one supplier against a door-to-door quote from another is how an apparent price advantage disappears at the port. Ask everyone to quote on the same terms.
6. Place the order and choose the shipping mode. Sea freight is the cheapest way to move volume and takes one to two months, air freight brings that down to one or two weeks, and express couriers like DHL and FedEx deliver in three to five days while costing the most by weight. The mode also has to fit the size of the order: shipments above roughly 200kg (440lbs) generally move as freight through a forwarder instead of going out with an express courier, so if your first run is sized above that line, have a forwarder engaged before the goods are ready to leave the factory.
Landed cost is what one unit costs you sitting in an Amazon fulfillment center ready to sell. You want that number before the deposit goes out, while you can still walk away from the quote. The figures in the example below are illustrative and round so the structure stays visible, and the exercise only pays off once you substitute your own quote, your own freight number, and your own duty rate.
Say a supplier quotes $4.20 per unit FOB on an MOQ of 500 units, so the production order comes to $2,100. Your forwarder then quotes $700 to move and clear that shipment by sea, which spreads to $1.40 a unit and puts you at $5.60 a unit before duty.
Duty is the one line you look up instead of estimating. The rate depends on how your product classifies under the Harmonized Tariff Schedule, and it varies widely between categories that look similar to anyone who is not a customs broker. Search your product at hts.usitc.gov, find the heading that genuinely describes it, and apply that rate to the customs value of your shipment. Any general-purpose duty percentage you read in a sourcing article was written about somebody else's product.
Now the Amazon side. Assume a target retail price of $24.99 for an item that weighs 15 ounces packed and ships as small standard-size:
| Line | Per unit |
|---|---|
| Supplier price (FOB) | $4.20 |
| Inbound freight and clearance | $1.40 |
| Import duty | your HTS rate |
| Amazon referral fee (15%) | $3.75 |
| FBA fulfillment fee (14 to 16 oz, small standard) | $3.70 |
| Fuel and logistics surcharge (3.5%) | $0.13 |
| Storage | about $0.08 |
| Total cost before duty | $13.26 |
| Left from a $24.99 sale | $11.73 |
Four of those lines come straight from Amazon's published schedules, and each of them moves for a different reason as your product changes:
That leaves $11.73 a unit before duty, before advertising, and before returns, on a product costing $5.60 to land. Two sanity checks are worth running on your own version of the table. First, whatever margin you calculate still has to absorb your duty rate and your ad spend, so a table that only just clears your bar before those lines is already under water. Second, the MOQ decides how much cash the SKU ties up: 500 units at $5.60 landed is $2,800 committed to inventory that has not sold yet, and that number matters as much as the margin percentage when you are choosing between two products. This table also leaves out your selling-plan subscription, which our guide to setting up an Amazon seller account covers along with the rest of the registration process.
Trade Assurance is the platform feature to understand before anything else, because it is the payment protection. It works like escrow: Alibaba holds your payment until the order has been fulfilled, which leaves you with leverage if what arrives does not match what you ordered. Keep the order inside Alibaba's own order flow so the protection applies, and treat a supplier who pushes for a bank transfer off the platform as a supplier asking you to give that protection up.
The rest of what the platform gives you is ordinary but useful: sample requests handled through the same order flow, supplier messaging that puts your specification in writing where it can be referenced later, and a visible transaction history for every seller. Use the messaging deliberately, because a written thread covering materials, tolerances, packaging, and labeling is the record you will point at if the production run comes back wrong, and it costs nothing to build while you are negotiating anyway.
The table you build before the deposit is also the tool you run the product with afterward, since most of the decisions that follow are the same arithmetic with updated inputs.
Let lead time set the reorder date. Production time plus one to two months at sea means that by the time inventory looks low, anything you order now lands well after you have already run out. Work backwards instead: add your supplier's stated production window to the transit time for the mode you use, convert that into units at your current sell-through rate, and reorder when inventory drops to that level.
Renegotiate at the next quantity break. After the first run sells through you have something the supplier did not have when they quoted you, which is a real sell-through rate and a repeat order to place. Ask for the price at the next quantity tier then, and run the new figure back through the table, because anything you take off the FOB line drops through to every unit you sell after it.
Time inventory against the storage window. The October through December rate is roughly three times what you pay the rest of the year, so a shipment that lands in September and sits gets billed at the peak rate for its last three months in the warehouse. Size the pre-peak shipment to what you expect to sell inside the window, and let the rest arrive after the rate drops in January.
Know when to drop the SKU. If the table leaves only a thin margin before duty and advertising, walk away while the decision still costs you nothing but a sample order, because once the deposit clears and the container lands you own the whole run and the cash stays locked up until the units sell or get liquidated. Ordering more of a unit that barely covers its own fees only puts more cash into the same problem. Our guide to building an Amazon FBA business covers how this fits alongside the rest of the operation.
