Amazon FBA product sourcing options include: wholesale (buying branded products to resell), private label (your own brand manufactured overseas), retail arbitrage (buying discounted retail products), and online arbitrage.
For scalable FBA businesses, private label or exclusive wholesale relationships provide the best long-term margin protection. Open-catalog wholesale creates pricing pressure from other sellers on the same listing.
When evaluating suppliers, get 3–5 competing quotes for the same spec. The lowest cost supplier is not always the best choice — evaluate minimum order quantity, lead time, payment terms, and quality consistency.
Factor your full landed cost before committing to a product. A $3 ex-factory product with high tariffs and fragile packaging may end up at $7–8 landed, which changes the FBA economics entirely.
