Amazon Dropshipping vs FBA: The Policy Rules and Why Taiwan Brands Should Choose FBA

Amazon's dropshipping policy (Seller Central Help → Dropshipping Policy) permits dropshipping under specific conditions. The core requirement: you must be the "seller of record" on all documentation. The customer must receive a package showing you (the seller) as the seller — not your supplier or a different retailer. Amazon explicitly prohibits buying products from another retailer (e.g., Walmart or another Amazon seller) and having them ship directly to your customer.

Compliant dropshipping on Amazon looks like: you list your own product, a customer orders, your manufacturer or 3PL fulfills the order with your branding and your packing slip. The packing materials must display your company name as the seller — no third-party retailer names, logos, or promotional materials.

Commonly violated rules: sellers who source from AliExpress, DHgate, or other marketplaces and have those suppliers ship directly to Amazon customers — with the supplier's branding on the package — are violating Amazon's dropshipping policy. This can result in listing removal and account suspension.

Prime badge: FBA listings display the "Prime" badge, which signals 2-day (or faster) free delivery to Amazon Prime members. Studies consistently show Prime-eligible products convert at 3–5x the rate of equivalent non-Prime products in the same search results. Most dropshipping setups cannot offer Prime shipping, creating a significant conversion disadvantage.

Buy Box priority: Amazon's algorithm heavily favors FBA sellers for Buy Box ownership. FBA's shipping speed and reliability metrics give it a structural advantage over Merchant-Fulfilled listings, including dropshipped products. Without the Buy Box, your listing generates very few sales.

Delivery time: standard dropship fulfillment from Taiwan to US customers takes 7–25 days. FBA delivers in 1–2 days. In a market where consumers expect Prime speed, 2-week delivery for a non-Prime item generates negative reviews, A-to-Z claims, and low conversion.

Customer service and returns: FBA includes Amazon's customer service for delivery issues and a standard 30-day return policy managed by Amazon. Dropship sellers must handle their own customer service and returns. Poor customer service from dropship operations is a consistent driver of account health problems.

Testing demand: before investing in a full FBA inventory order ($5,000–$20,000+), some sellers use FBM (Fulfilled by Merchant, including dropshipping with compliant suppliers) to validate demand. If the product gets orders, move to FBA. If it does not, no large inventory investment was wasted.

Oversized and heavy products: very large products (furniture, gym equipment, large appliances) can be expensive to store in FBA due to oversize fees. For certain oversized products, a manufacturer-direct-to-customer fulfillment model (technically dropshipping) can be cost-competitive if you can maintain delivery commitments.

B2B custom orders: for large B2B orders where customization or direct factory shipment is involved, a factory-direct fulfillment model outside Amazon makes sense. These are typically not Amazon marketplace transactions anyway.

For the vast majority of Taiwan consumer brands targeting US Amazon consumers, FBA is the correct model. The conversion rate advantage from the Prime badge alone — 3–5x higher conversion — almost always compensates for FBA's fees when you model the true unit economics.
