How to Source Products for Amazon FBA from China

Sourcing products for Amazon FBA from China works when three things line up: a product with real margin after fees, a supplier who understands Amazon's prep rules, and a shipping plan that doesn't eat the profit. Most failed FBA imports trace back to one of those three breaking down. A factory can make a great product and still sink your listing if the FNSKU labels are wrong, the polybags are too thin, or the cartons arrive mixed.

China remains the dominant supply base for private-label FBA sellers. Factories in Guangdong and Zhejiang have handled Amazon-bound orders for over a decade, and many now offer FBA prep as a standard line item. The challenge is not finding a supplier. It is finding one whose work survives Amazon's receiving dock, and knowing enough to check. CN Ally helps sellers do both: shortlisting factories with genuine FBA experience, verifying they can meet prep specs, and coordinating quality checks before the goods leave China.

This guide walks the full sequence: choosing a product with real margin, vetting suppliers for FBA competence, the prep and labeling rules they must follow, supplier prep versus prep centers, shipping options to the fulfillment center, and the landed-cost math that decides whether to order at all.

What makes a product worth sourcing for FBA?

A product is worth importing when its landed cost plus Amazon's fees leaves a margin you can live with after ads and returns. Sellers who pick products on factory price alone often discover the math collapses at checkout.

Filter candidates through these checks before talking to any supplier:

• Price band. Products selling between roughly $20 and $70 tend to work best for private label FBA. Below that, fees and shipping absorb too much of the price. Above it, conversion gets harder. A rule of thumb, not a law.
• Size and weight. Small, light, non-fragile products keep fulfillment fees manageable and survive ocean freight without special packaging. Every size-tier jump in Amazon's fulfillment fee table is margin gone forever.
• Simplicity. Moving mechanical parts, battery-powered electronics, and anything ingestible multiply compliance and return risk. A simple product with no power source is the calmest first import.
• Differentiation potential. If the product is identical to forty listings, you are buying a price war. Private label means changing something: better materials, a bundle, improved packaging, an accessory the factory can add cheaply.
• Stable demand. Confirm the category sells year-round, not in a two-month spike. Seasonal products can work, but ordering one as your first container is how sellers end up warehousing holiday stock until July.

Also check restricted categories early. Some products need Amazon approval before listing, and items like ingestibles or children's products carry testing and certification costs. Confirm gating and compliance before you fall in love with a product.

How do you find suppliers that actually understand FBA?

Search Alibaba for your product and you will find hundreds of suppliers claiming FBA experience. "We have many Amazon customers" is the most common sentence in China export sales, and it is almost never verified. The interview is what separates real competence from a sales script. Ask these in writing, before ordering samples:

• What is FNSKU, and where does it go? A supplier with real FBA work answers without hesitation: Amazon's fulfillment network stock keeping unit, a barcode on every unit, placed on a flat surface, never on a seam. Vague answers are disqualifying.
• What polybag thickness do you use, and do you print suffocation warnings? The correct answer: 1.5 mil minimum, sealed, with a printed warning on bags whose opening measures 5 inches or more. A supplier offering 1.0 mil bags "to save cost" has never cleared Amazon receiving.
• One SKU per carton, or can you mix? Correct answer: one SKU per master carton. Mixed cartons cause receiving errors and are a classic rookie-supplier mistake.
• Can you send photos of a previous FBA shipment's cartons and labels? Experienced suppliers have these photos: cartons with Amazon shipment labels, correctly placed FNSKU stickers, clean packing. No photos, no claimed experience.
• How do you handle prep errors? Listen for specifics rather than "very good quality." Suppliers who track their defect rate are the ones worth paying.

Response quality matters as much as content. Suppliers who answer precisely and attach photos unprompted are almost always easier through a full production run than the cheapest bidder answering in one-liners.

What should the supplier's quote include beyond unit price?

An FBA quote showing only a unit price is incomplete. By the time goods reach the warehouse, the real cost includes line items the factory controls. Get each one in writing before comparing suppliers:

• Unit price at your target quantity, with price breaks at the next two tiers.
• FBA prep line items. Polybagging per unit, FNSKU label printing and application, carton labeling, any bundling or kitting. Some factories include basic prep free; others charge a few cents per unit. Get the number.
• Export carton specs. Dimensions, units per carton, gross weight per carton. You need this to plan the shipment and check Amazon's carton rules.
• Packaging. What the retail packaging is, and what an upgrade costs. Amazon-bound products take more handling than domestic retail stock, and thin color boxes arrive crushed.
• Payment terms and lead time. First-order terms are usually 30% deposit with the balance before shipment; lead times run several weeks from deposit to cargo-ready. Confirm both.
• The Incoterm. EXW, FOB, or DDP to the Amazon warehouse. A DDP quote covering freight, duties, and delivery is easiest to compare against FOB plus separate logistics, as long as you compare like with like.

How do samples and quality control work for FBA orders?

Never place a production order without an approved sample. For FBA, the sample review has an extra dimension: you are checking Amazon-readiness, not just the product.

Check the product first: materials, finish, function, dimensions against your spec sheet. Then check the Amazon layer. Is there a flat, clear area on the packaging for the FNSKU label? Does the polybag meet the 1.5 mil rule with a printed suffocation warning? Is the retail packaging sturdy enough to survive a container and a fulfillment center? Request a second sample if the first fails any of this. Sample cost is trivial next to a rejected shipment.

Before the production run, arrange a pre-shipment inspection: a statistical sample of finished, packed cartons checked against your requirements for product quality, labeling accuracy, polybag compliance, carton markings, and quantities. For first orders with a new supplier, this is the highest-return money in the process. Third-party inspections catch the labeling errors and mixed cartons that Amazon penalizes at receiving.

One specific FBA trap: suppliers sometimes produce the order correctly but pack it wrong. The product is fine; the cartons are the problem. Mixed SKUs, FNSKU labels on seams, missing warnings. These defects are invisible in product photos and catastrophic at the Amazon dock, which is exactly why the inspection exists.

What are Amazon's FBA prep and labeling rules?

Amazon rejects or penalizes shipments that break its prep rules, and "close enough" is how inventory ends up stranded or sent to Amazon's own prep service at your expense. The key requirements, per Amazon's published prep guidance and current seller guides:

• FNSKU on every unit. Each sellable unit needs its FNSKU barcode on the outer packaging, scannable, on a flat surface, never on a seam or edge. Cover or remove other barcodes so the scanner reads the right one.
• Polybags: 1.5 mil minimum. Items requiring bagging, such as textiles, liquids, or multi-piece sets, must be in sealed transparent polybags at least 1.5 mil (0.0015 inches) thick. Bags with an opening of 5 inches or more, measured flat, need a printed suffocation warning.
• Carton labels from your shipment plan. Every carton needs the Amazon shipment label generated in Seller Central when you create the inbound shipment.
• One SKU per carton. Do not mix products in the same box; it causes receiving errors.
• Heavy package markings. Cartons over 50 lb need a "Heavy Package" label; over 100 lb need "Team Lift." Plan carton weights accordingly.
• Expiration dates where applicable. Grocery, health, and beauty products need clear dates on both the unit and the outer packaging.

The table below covers the most commonly missed rules. Send it to your supplier as a checklist before production finishes.

Requirement · The rule · Common failure

• FNSKU label: Scannable barcode on every unit, flat surface · Label on a seam, or old barcode not covered
• Polybag thickness: Minimum 1.5 mil, sealed · Supplier uses 1.0 mil to save money
• Suffocation warning: Printed warning when bag opening is 5+ inches · Warning missing entirely
• Carton contents: One SKU per master carton · Mixed SKUs in one box
• Carton labels: Amazon shipment label on each carton · Labels from an old shipment reused
• Weight markings: "Heavy Package" over 50 lb, "Team Lift" over 100 lb · Overweight cartons unmarked

Two references worth bookmarking: SellerSonar's 2026 FBA packaging guide and Zbao Logistics' polybag requirements guide. Amazon keeps tightening prep enforcement, so confirm the current requirements in Seller Central before each shipment, especially your first.

Should the supplier handle prep, or should you use a prep center?

Three realistic options, and the right one depends on your supplier's competence and order size.

Option · How it works · Best when · Watch out for

• Supplier prep: Factory applies FNSKU, polybags, and carton labels · Supplier has proven FBA experience with photo evidence · No independent check before goods leave China
• China prep warehouse: Goods go to a China warehouse for inspection, labeling, repacking · You want QC plus prep in one stop near the factory · Adds handling time and a second handoff
• US/EU prep center: Goods ship bulk to a prep center near Amazon, which preps and forwards · Supplier can't do prep reliably, or you consolidate from several factories · Highest per-unit cost; adds domestic transit

For a first order with a new supplier, the China prep warehouse route is often the sweet spot: an independent pair of eyes on labeling and packaging before the container sails, cheaper than fixing problems from across the ocean. Once a supplier has delivered two or three clean shipments, moving prep back to the factory saves money without much added risk.

Direct-to-Amazon shipping from the factory is cheapest and riskiest. It works with suppliers you trust deeply. With a new supplier, it is a gamble where the downside is a rejected shipment sitting in a foreign warehouse.

How do you ship from China to an Amazon fulfillment center?

Most sellers choose between three modes, and the decision is mostly speed versus cost per unit.

• Express (DHL, FedEx, UPS). Three to seven days door to door. For samples and small urgent restocks, never for a full inventory order; the per-unit cost destroys margin.
• Air freight. Roughly one to two weeks. Sensible for mid-size restocks of light, high-value products when a stockout would cost more than the freight premium.
• Sea freight. Thirty to forty days port to door on US routes, sometimes longer. The default for initial orders and planned restocks. LCL (shared container) suits shipments up to about 15 CBM; above that, a full container usually costs less per unit.

With DDP shipping, the forwarder handles export clearance, freight, import customs, duties, and final delivery to the Amazon warehouse in one quoted price. Ask specifically whether it includes Section 301 duties for US-bound goods; these apply to many China-origin products and are a common source of surprise charges.

One sequencing detail that matters: create the shipment plan in Seller Central before the goods leave China. Amazon assigns inventory to specific fulfillment centers, and the carton labels applied in China must match that plan. Shipping first and planning later leads to misdirected freight.

How do you check the margin math before ordering?

Build a simple landed-cost model before committing to anything. This is the step that kills bad products early.

Cost component · What to include

• Product cost: Unit price x quantity
• FBA prep: Polybagging, labeling, kitting per unit
• Freight: Sea, air, or express quote, allocated per unit
• Import duties: Duty rate for your HS code x customs value; include Section 301 for the US
• Amazon referral fee: Percentage of sale price; varies by category, often 15% in many categories
• FBA fulfillment fee: Based on size tier and weight; check Amazon's current schedule
• Storage: Monthly per cubic foot; higher in Q4
• Returns and ads: A realistic reserve based on your category

Total everything per unit, subtract from your planned sale price, and look at what remains. A common target is 25 to 30 percent net margin after all costs, leaving room for ad spend and the occasional bad month. If the model only works at a sale price the market won't support, the product is wrong, not the math.

Two mistakes show up constantly. First, forgetting import duties entirely, which is easy when the supplier quotes DDP and the duty hides inside the forwarder's number. Second, modeling fees on today's numbers while ignoring that storage fees spike in the fourth quarter. If you hold inventory through the holidays, model Q4 storage.

What are the most common FBA sourcing mistakes?

• Ordering before the listing exists. Create the listing and secure any required category approvals first. Inventory arriving for a listing you cannot activate is dead capital.
• Skipping the sample. Every experienced seller has a story about the order placed on photos alone. It never ends well.
• Letting the supplier choose the packaging. Factories optimize for cost, not for surviving Amazon's inbound process. Specify polybag thickness, warning print, and carton strength yourself.
• Shipping without a pre-shipment check. The inspection costs a fraction of one rejected shipment. First orders with new suppliers should always be inspected.
• Underestimating total lead time. Production plus inspection plus sea freight plus Amazon check-in can easily total two to three months. Order before you need the stock.
• Ignoring compliance. Electronics, toys, cosmetics, and children's products carry certification and testing requirements in the US and EU. A product that cannot legally be sold is not a bargain at any price.

Frequently asked questions

Can a Chinese supplier ship directly to Amazon FBA?

Yes, and many do it routinely. The supplier applies your FNSKU labels, polybags to spec, labels cartons with your Amazon shipment labels, and hands the freight to a forwarder shipping DDP to the fulfillment center. It works well with suppliers who have proven FBA experience. For a first order with a new supplier, route through an inspection or prep warehouse instead, so labeling errors get caught before the goods sail.

What is FNSKU and how is it different from a UPC?

A UPC is the manufacturer barcode identifying the product globally. An FNSKU is Amazon's own identifier tying your inventory to your seller account, so Amazon tracks your stock separately from other sellers' identical products. You print FNSKU labels from Seller Central; the supplier or prep center applies one to each unit.

How much does FBA prep cost per unit in China?

It varies by product and service level, but basic prep, polybagging plus FNSKU labeling, typically runs from a few cents to around half a dollar per unit at Chinese factories and prep warehouses. Kitting, bundling, and fragile-item protection cost more. Get it as a written line item on the quote rather than accepting "prep included."

Do I need a prep center if my supplier offers FBA prep?

Not necessarily. If the supplier has documented FBA experience and you verify the first shipment with an inspection, supplier prep is cheaper and simpler. A prep center earns its fee when the supplier is unreliable at prep, when you consolidate from several factories, or when you want an independent quality check built into the workflow.

How long does it take to get products from China to Amazon?

Plan on two to three months end to end for a first order: several weeks of production, days for inspection and prep, thirty to forty days of sea freight to the US, plus customs, delivery, and Amazon check-in. Air freight cuts transit to one to two weeks but costs far more per unit.

What happens if my shipment fails Amazon's prep requirements?

Amazon may refuse the shipment at the dock, send it to its own prep service and bill you, or flag inbound defects against your account. Repeated defects can restrict your ability to send inventory. This is why the pre-shipment inspection matters: every one of these outcomes costs more than catching the problem in China.

A decision rule before you place the order

Place the order only when four boxes are checked: the margin model clears your target after fees, duties, freight, and a returns reserve; the sample passed both product and Amazon-prep checks; the supplier proved FBA competence with photos and precise answers rather than claims; and a pre-shipment inspection is scheduled before the balance payment. Miss any one and you are not saving money, you are scheduling a problem.

Getting this right once creates a reusable template: the same supplier interview, the same prep checklist, the same cost model. CN Ally runs this process for sellers end to end, from shortlisting FBA-experienced factories to coordinating inspections and factory audits before goods ship.
