ShippingCowAmazon Seller Fulfilled Prime for items over 50 lb: qualification requirements
Items over 50 lb can hold the Prime badge through Seller Fulfilled Prime (SFP), but they sit in Amazon's extra large size tier, which has its own delivery-speed targets. To qualify, you need a Professional selling account with a US address and a passed 30-day trial, then you must keep meeting Amazon's published on-time delivery, valid tracking and cancellation minimums. A 3PL can do the shipping for you, but the performance bar stays on your account.
What the program asks of a heavy-item seller
Prequalify, pass a 30-day trial, then hold Amazon's performance bar every month. Heavy items add one wrinkle: they are measured in their own size tier, so a weak extra-large result does not pull down your standard-size offers.

Questions
Does Amazon let items over 50 lb into Seller Fulfilled Prime at all? +
Yes. SFP has three size tiers: standard-size, oversize and extra large. Heavy items, roughly 50 lb and up, sit in the extra large tier. Amazon measures each tier's performance independently, so a weak extra-large score does not pull down your standard-size offers (Amazon Seller Central, "Seller Fulfilled Prime performance requirements," G202072550, accessed 2026-10-15).
What are the qualification steps? +
Two steps, both documented on Amazon's public program page: prequalify, then pass a 30-day trial. To prequalify you need an Amazon Professional selling plan, a US address as your default shipping address, and a history of meeting prequalification performance requirements for late shipment, valid tracking and cancellation. To pass the trial you ship for 30 days and meet the full performance requirements (Amazon, sell.amazon.com "Seller Fulfilled Prime," accessed 2026-10-15).
What are the exact prequalification numbers? +
Amazon's public page names the categories but does not publish exact figures, and secondary sources report different numbers. Treat any figure you read elsewhere as unconfirmed and check the current bar in Seller Central before you commit inventory.
What performance must I keep once I'm in? +
Amazon's published bar covers on-time delivery, valid tracking and pre-fulfillment cancellations, shipping six days a week (Saturday included), and routing nearly all Prime orders through Amazon Buy Shipping. Read the current minimums on the Seller Central performance requirements page (G202072550, accessed 2026-10-15).
What delivery-speed targets apply to heavy items? +
Amazon sets targets per size tier, measured as a share of orders delivered in 1, 2 or 5 days. The extra large tier has the loosest targets and no 1-day requirement. Oversize items face stricter ones. Read the current figures on the performance requirements page (G202072550, accessed 2026-10-15).
Is there a minimum monthly volume? +
Yes. If you ship fewer than 100 SFP packages a month, or ship them inconsistently, Amazon limits your daily Prime order volume until you resume consistent shipping of at least 100 SFP packages a month (Amazon Seller Central, "Seller Fulfilled Prime program policy," G201812300, accessed 2026-10-15).
Can heavy items realistically hit these numbers? +
It depends on your warehouse location and carrier mix. Extra-large items get the loosest speed targets of the three tiers, but you still need six-day operations, same-day pickup discipline and Buy Shipping on nearly every order. That is why heavy-item sellers often run SFP through a 3PL that already operates on a weekend schedule rather than staffing it themselves.
