Amazon Fulfilled vs Seller Fulfilled: 5 Ways to Get Prime in 2026
Quick answer: A Prime badge on Amazon comes from one of two places: stock held inside Amazon's US fulfillment network (FBA, or "sold by Amazon" vendor stock), or stock you ship yourself from a US location under Seller Fulfilled Prime (SFP). Amazon has also added ways to feed FBA from bulk storage, including AWD in the US and, since April 2026, a hub in Shenzhen, plus Buy with Prime to carry the badge onto your own website. Orders shipped one by one from China never get the badge. For most sellers sourcing from China, the realistic route is FBA with stock that arrives prepped and labelled.
Why the badge is worth chasing
Prime shoppers filter for it, Amazon shows fast delivery dates next to it, and on crowded listings an offer without it often goes unseen. The fulfillment choice behind it is really a choice about where your stock lives and who is responsible when a delivery promise is missed. This article compares the routes to the badge only. For the full cost comparison of FBA and seller fulfillment, see our FBA vs MFN breakdown.
The five routes
1. FBA: stock in Amazon's fulfillment centers
Eligible FBA offers get the badge automatically. Your job is getting stock in and keeping it there. Since January 1, 2026 Amazon no longer preps or labels inventory for US FBA, so units have to arrive with the right labels and packaging. Since March 31, 2026, when Amazon ended commingled inventory, sellers without the Brand Representative role in Brand Registry need an FNSKU label on every unit. Amazon also sets monthly capacity limits in cubic feet and charges a low-inventory fee when you hold less than 28 days of supply. The badge stays on as long as the stock does.
2. FBA fed from bulk storage: AWD or Amazon's Shenzhen hub
The badge still comes from FBA, but the cartons wait somewhere cheaper first. Amazon Warehousing and Distribution (AWD) stores bulk inventory in the US and replenishes your FBA stock from it. Since April 9, 2026, Amazon's Global Warehousing and Distribution (GWD) facility in Shenzhen does the same from China: you store stock there and Amazon moves it into its US network when needed, through Amazon Global Logistics. Amazon says GWD storage costs up to 45% less than AWD in the US. Either way, the same prep and labelling rules apply before the goods go in.
3. Seller Fulfilled Prime: your own US warehouse or 3PL
You keep the stock and ship each Prime order yourself, under Amazon's strictest targets: a US ship-from address, at least 93.5% on-time delivery checked weekly, under 0.5% cancellations, and, since July 6, 2026, one-day delivery dates on 40% of Prime page views for standard-size items. Our complete SFP guide covers the trial and every metric.
4. Sold by Amazon (1P vendor)
If Amazon buys your stock wholesale through Vendor Central, its own offer carries the badge. It is invitation-only, and Amazon has been trimming smaller vendors since 2024. See Amazon 1P vs 3P.
5. Buy with Prime: the badge on your own website
Buy with Prime lets Prime members check out on your Shopify or other store with Prime delivery. It is US-only and requires your stock to sit in Amazon's fulfillment network, so it builds on routes 1 or 2 rather than replacing them. The orders are filled through Amazon's off-Amazon fulfillment; read our Multi-Channel Fulfillment guide for how that side works.
The routes compared
| Route | Where stock sits | Who ships the order | Main hurdle | Fit for China-sourced sellers |
|---|---|---|---|---|
| FBA | Amazon fulfillment centers | Amazon | Arriving prepped and labelled; capacity limits | Best starting point |
| AWD / GWD to FBA | Amazon bulk storage in the US, or Shenzhen | Amazon | Extra planning layer; same prep rules | Good once volumes are steady |
| Seller Fulfilled Prime | Your US warehouse or 3PL | You or your 3PL | Weekly metrics, speed coverage, weekend shifts | Later stage, needs a US network |
| Sold by Amazon (1P) | Amazon, after buying your stock | Amazon | Invitation only | Rarely available |
| Buy with Prime | Amazon's network | Amazon | US store and Amazon-held stock required | An add-on once you use FBA |
What does not get you Prime
- Merchant fulfilled orders from China. Fine for testing products, but transit takes days, not the one or two days the badge promises.
- Premium Shipping. This is a faster delivery option for seller-fulfilled offers. It is not the Prime badge, though since mid-2026 it carries a 93.5% on-time target reviewed weekly.
- Your own 3PL without SFP approval. A fast US 3PL improves your delivery dates, but the badge only appears after you pass the SFP trial.
How to choose: four questions
- Is your stock already in the US? If not, you are choosing between FBA and FBA fed from GWD. SFP comes later.
- Do you sell more than 100 Prime packages a month, every week? If not, SFP's volume and weekly reviews will be hard to sustain. Use FBA.
- Is the product bulky, heavy or slow-moving? FBA fees and storage hurt most here. A US 3PL with SFP, or AWD as a buffer, may cost less.
- Do you also sell on your own site? Stock in Amazon's network can serve both channels through Multi-Channel Fulfillment, and Buy with Prime can put the badge on your checkout.
Keeping the badge: what breaks each route
| Route | Common way to lose the badge | Prevention |
|---|---|---|
| FBA | Stocking out, or a shipment held at check-in for missing labels or poor packaging | Reorder on lead time, not on gut feel; label and pack before the goods leave the factory |
| AWD / GWD | Replenishment not reaching FBA in time | Watch the transfer lead time; keep a buffer during Q4 |
| SFP | A bad week of late deliveries or cancellations | Buy protected labels through Amazon, hold US safety stock, staff weekends |
Most lost badges on FBA trace back to supply problems: a late reorder or a carton that fails check-in. Our guide to Amazon order management and replenishment shows how to time reorders from China.

FAQ
What is the difference between Fulfilled by Amazon and seller fulfilled?
Fulfilled by Amazon (FBA) means your stock sits in Amazon's warehouses and Amazon ships each order, handles customer service and processes returns. Seller fulfilled means you or your 3PL store the stock and ship each order; it only carries the Prime badge if you qualify for Seller Fulfilled Prime.
How can I get the Prime badge without FBA?
Through Seller Fulfilled Prime, which requires a US ship-from address, a passed trial and weekly performance of at least 93.5% on-time delivery and under 0.5% cancellations. The only other route is selling to Amazon as a 1P vendor, which is invitation only.
Do products shipped from China get the Prime badge?
Not when each order ships individually from China. To get Prime, the stock has to be in Amazon's US network through FBA, possibly staged at Amazon's Shenzhen GWD hub first, or in a US warehouse that qualifies for Seller Fulfilled Prime.
What is Amazon GWD?
Global Warehousing and Distribution is an Amazon bulk storage facility in Shenzhen that opened on April 9, 2026. Sellers store inventory there and Amazon replenishes their US fulfillment centers from it, using Amazon Global Logistics for the cross-border leg.
Is FBA or Seller Fulfilled Prime better for keeping the Prime badge?
FBA is easier to keep because Amazon handles delivery; you mainly have to stay in stock and send compliant shipments. SFP gives more control and can cost less for bulky or multichannel stock, but one bad week of late deliveries can cost you the badge.
