Sourcing from China is how most Amazon FBA sellers build healthy margins, but the FBA model adds a layer of rules ordinary importers never face. Get the packaging wrong and Amazon rejects your shipment. Misjudge the shipping timeline and you stock out right before peak season. This guide walks through the full workflow — from demand forecast to delivered inventory — so your first (or tenth) container lands in the fulfillment center without surprises.
Forecast Demand and Plan Your Replenishment Rhythm
FBA success starts before you contact a factory. You need a realistic forecast of how many units you can sell, because ordering too much ties up cash in slow-moving inventory, while ordering too little triggers the stockouts that kill your BSR ranking. Start with your unit economics: target at least a 3x markup over landed cost, and model your break-even volume before you commit to a tooling fee.
Map your replenishment cycle on a calendar, not in your head. A typical cycle is about 90 to 120 days end to end: 30 to 45 days of production, 25 to 35 days on the ocean, plus customs and inbound processing at Amazon. If you sell 500 units a month, you must reorder when you have roughly 1,000 to 1,500 units left, not when the shelf looks low.
Pay special attention to seasonal peaks. Q4 demand can double or triple, and lead times stretch as factories fill up and ports get congested. Order your holiday stock earlier than feels comfortable — most sellers underestimate how long peak-season freight actually takes, and the penalty for missing Q4 is a year of lost ranking.
Supplier Qualification Standards for FBA Sellers
Not every factory is a fit for e-commerce. FBA sellers need suppliers who understand small test orders, private-label customization, and tight deadlines. When shortlisting, look for:
- Existing experience exporting to Amazon sellers or to your target market.
- Willingness to support an MOQ that matches your first forecast, not one tied to a full truckload.
- Ability to customize packaging, branding, and inserts to your design files.
- A QC process that lets you book a pre-shipment inspection before the balance is paid.
- Stable communication in English and realistic lead times in writing.
Always order samples before bulk production, and compare at least three suppliers on total landed cost, not just unit price.
Vetting should never stop after your first order. Track on-time delivery, defect rates, and communication quality across every shipment, and be ready to qualify a backup supplier before your main one slips. When your main factory gets busy or raises prices, having a second qualified option keeps your listings alive.
FBA Packaging, Labeling, and Prep Requirements
This is where new sellers lose the most money. Amazon has strict rules, and non-compliant shipments are rejected, relabeled at your expense, or destroyed. Before production starts, send your factory the current FBA packaging and prep guidelines and confirm they can follow them.
- FNSKU labels — every unit needs a scannable FNSKU barcode; factory-applied labels are cheaper than Amazon’s prep service.
- Carton labels and box content info — accurate shipping labels and weight/dimensions for every master carton.
- Poly bags and suffocation warnings — for any loose or plastic-packaged items, with correct warning labels.
- Set and bundle prep — multi-packs must be clearly labeled as sold as a set.
- Item protection — fragile, liquid, or battery-containing items need approved packaging that survives a long ocean trip.
Decide early whether your factory applies labels or a third-party prep service does. Factory labeling is usually cheaper and catches errors while production is still open.
Ocean Freight Timelines and Stockout Risk
Air freight is fast but can erase your margin; sea freight is cheap but slow. Most FBA sellers use sea freight for regular stock and air freight only for urgent top-ups. Build buffer into every order: a 15 to 20 percent safety stock for your best sellers absorbs port delays, customs holds, and Amazon receiving backlogs. Remember that timelines stretch around Chinese New Year and major holidays — plan those orders weeks earlier.
Never send inventory so tight that a two-week delay means an empty listing. A stockout resets your ranking and ad efficiency, and recovering takes far longer than the extra holding costs.
Common Mistakes New FBA Sellers Make
- Skipping pre-shipment inspection and discovering defects only after Amazon receives the goods.
- Choosing the cheapest supplier without checking FBA experience, leading to rejected cartons.
- Under-estimating landed costs — duties, freight, prep, and storage can add 30 to 50 percent to the factory price.
- Ordering a single huge shipment with no backup supplier, leaving no room to fix mistakes.
- Forgetting long-term storage fees and aged-inventory surcharges that Amazon charges on slow-moving stock.
