Top Opportunities
Critical · Quick Win
Right-size the carton: you are billed for 8.5 lb, not 2.40 lb
$0.74per unit
Amazon bills Large Standard items on the greater of unit weight and dimensional weight (L × W × H ÷ 139). Your 14.2 × 10.4 × 7.9 in carton has a dimensional weight of 8.4 lb, rounded up to 8.5 lb - more than three times the 2.40 lb product inside.
Action: Move to a 10.6 × 10.0 × 7.9 in carton with molded-pulp corners instead of loose void fill. Billed weight drops to 6.25 lb. 2026 Large Standard fee for items over $50: $7.23 + $0.08 per 4 oz above 3 lb, so $8.99 now vs $8.27 after - $9.30 vs $8.56 with the 3.5% fuel surcharge. Keep the shortest side at 8 in or less, or the unit moves to Small Bulky and costs more. Net savings: $0.74/unit.
Critical
Switch inbound shipments from Minimal split to Amazon-optimized splits
$0.73per unit
If you ship on a Minimal split (everything to one location), you pay about $1.08/unit in inbound placement fees for this size and weight. Since Jan 15, 2026, Amazon-optimized splits carry no placement fee.
Action: In Send to Amazon, choose Amazon-optimized splits. You ship to 4 locations instead of one, so carrier cost rises - about $0.35/unit for this product. Net savings: $0.73/unit.
Important
Avoid the Low-Inventory-Level (LIVE) fee - restock earlier
$0.16per unit
If both your 30- and 90-day days of supply fall into the 21-28 day band, a Large Standard 3-20 lb item pays a $0.47/unit LIVE fee. Assuming that happens on about a third of your units, it costs $0.16/unit blended.
Action: Raise your reorder point so days of supply stay above ~35 (Amazon charges below 28; the extra week is your buffer). Net savings: $0.16/unit blended.
Important
The smaller carton cuts storage too - most of all in Oct-Dec
$0.23per unit
Storage is billed per cubic foot: $0.78/cu ft in Jan-Sep and $2.40/cu ft in Oct-Dec for standard-size items. The new carton takes 0.48 cu ft instead of 0.68 (-28%).
Math: with about one month on hand per unit, storage averages $0.80/unit now vs $0.57/unit with the new carton. In Oct-Dec alone it is $1.62 vs $1.16 per unit per month. Net savings: $0.23/unit blended.
Nice to have
Optional: certify the new carton for SIPP
≤$0.23per unit
Ships in Product Packaging (SIPP) gives standard-size items a small fulfillment discount - up to about $0.23/unit for Large Standard 3-20 lb. It needs ISTA-6 testing of the carton, so it pays off only at steady volume. Not included in the savings totals.
