Overview

Amazon is introducing a distinct “extra‑large” storage tier for Fulfillment by Amazon (FBA) inventory, separating it from the broader oversize category. The split takes effect this quarter and gives each tier its own capacity limits, which can change how many units sellers are allowed to send to fulfillment centers. Sellers with very big items—such as furniture, appliances, or large outdoor gear—need to understand the new limits to avoid unexpected shortfalls or excess.

Key Points

• New tier definition — Items that meet Amazon’s extra‑large dimensional criteria (greater than 108 inches on any side or over 150 pounds) are now classified separately from standard oversize products.
• Separate quantity caps — Each seller receives an independent inventory‑limit pool for extra‑large and for oversize items, instead of a single shared pool.
• Automatic re‑classification — Amazon’s system moves qualifying ASINs into the extra‑large tier without any action required from the seller.
• Performance‑driven allocations — The size of each pool is calculated from the seller’s recent sales velocity, forecasted demand, and the available space at the relevant fulfillment centers.
• Dashboard updates — Both the Inventory Performance Dashboard and the Restock Inventory page now display limits and usage broken out by the two large‑item tiers.

How the New Tier Works

1. Identify qualifying products — Amazon scans every FBA listing for dimensions and weight. For example, a 72‑inch‑wide patio table that weighs 120 pounds will be flagged and shifted from the generic oversize bucket to the extra‑large tier.
2. Allocate separate caps — After classification, Amazon computes two distinct caps. A seller who sold 5,000 units of a 30‑inch‑wide kitchen gadget last quarter might receive a 12,000‑unit oversize limit, while the same seller’s 2,000‑unit shipment of industrial shelving could generate a 4,000‑unit extra‑large limit.
3. Update seller dashboards — The next time the seller logs into Seller Central, the Inventory Performance Dashboard shows “Oversize Limit: 12,000 / Used: 8,500” and “Extra‑Large Limit: 4,000 / Used: 2,200.” The Restock Inventory page then suggests replenishment quantities based on the separate ceilings.
