Amazon Rebuilds FBA Large-Item Size Tiers for 2027 — 4 Bulky and 6 Oversize Tiers Replace Extra-Large, Overmax Fee Ends, Flat Product and Overhang Handling Fees Added
As part of its 2027 US fee update, Amazon is replacing its current two bulky tiers and four weight-based extra-large tiers with ten tiers: four bulky tiers and six oversize tiers defined largely by the item's longest side. The Overmax handling fee no longer applies from January 15, 2027; instead, oversize items that are flat (shortest side under 4 inches with a median side of 25 inches or more) pay a flat product handling fee, and the largest oversize tiers can also pay an overhang handling fee when the median side exceeds 43 inches. The net effect is mixed: some heavy but compact items get cheaper, while long or flat items can cost considerably more to fulfill.
Real-World Impact
Using PPC Land's worked examples (non-apparel, excluding the 3.5% fuel and logistics surcharge): a 65×20×7-inch, 62 lb TV drops from $48.57 to $36.55 per unit as it moves into medium oversize, while a 97×14.5×2-inch, 20 lb bulletin board rises from $50.93 ($33.93 plus the $17 Overmax fee) to $69.75 in long oversize — and a 70×44×3-inch, 50 lb tabletop panel goes from $70.32 to $97.48 once the $10.48 flat product and $3.45 overhang fees are added.
Key Points
- From January 15, 2027, the two bulky tiers become four (small, medium, large and extra-large bulky, all up to 50 lb and 130 in length + girth), with dimension limits of 28×24×20, 37×28×20, 52×28×28 and 59×33×33 inches
- The four weight-based extra-large tiers are replaced by six oversize tiers: small (longest side 72 in, 50 lb), medium (78 in, 70 lb), large (96 in, 150 lb), long (108 in, 150 lb, 165 in length + girth), special oversize light and special oversize heavy (over 150 lb)
- The Overmax handling fee, introduced January 15, 2026 for items over 96 inches long or 130 inches length + girth, no longer applies from January 15, 2027
- New flat product handling fee on oversize tiers when the shortest side is under 4 inches and the median side is 25 inches or more: $8.40 (small), $8.65 (medium), $9.42 (large), $10.48 (long), $21.67 (special light), $29.53 (special heavy)
- New overhang handling fee when the median side exceeds 43 inches, listed only for long oversize ($3.45), special oversize light ($5.23) and special oversize heavy ($10.45); items meeting both conditions pay both fees
- The 2026 tiers apply through January 14, 2027
What You Should Do Now
