Amazon Shipping published its 2026 peak season demand surcharges earlier this month. The window runs October 25, 2026 through January 16, 2027, with the highest rates from November 22 through December 26. That is not FBA. That is Amazon’s parcel delivery service stacking temporary fees on top of whatever contracted rate you already have.
If you ship DTC, Shopify, or multi-channel orders through a 3PL, this matters even if you never touch Amazon Shipping. FedEx already has Additional Handling and Oversize peak fees starting September 28. USPS temporary holiday package prices are lined up for early October. Everyone is pricing the same crowded calendar. The brands that lose money here are usually not “on the wrong carrier.” They are shipping the wrong shape.
What Amazon Shipping actually published
Per Amazon Shipping’s own peak surcharge page, during the three holiday windows you get:
- A per-package demand surcharge: $0.50, then $0.75 in the Nov 22–Dec 26 core, then $0.50 again
- Higher temporary amounts for Additional Handling, Large Package, and Extra Heavy Package fees in those same windows (for example, Additional Handling at $11.90 and Large Package at $117.50 in the core period)
Supply Chain Dive’s Sept 3 write-up matches those dates and notes the fees are higher than last year’s holiday schedule. Amazon says the surcharges apply automatically on top of contracted rates. No drama required. The invoice just gets heavier when volume is heaviest.
I am not going to pretend a random blog can quote your exact landed cost. Pull your own rate card, your own dimensional data, and your own Nov–Dec order history. The published peak layer is knowable. Your package mix is what turns it into margin damage.
What it means if you are growing past DIY fulfillment
Once you are in the 500+ orders a month range, peak surcharges stop being a spreadsheet curiosity. They show up as:
- Dim-weight and handling fees you thought you “avoided.” A soft-packable SKU in a rigid carton that is longer or girthier than it needs to be is a quiet tax all year. In November it gets louder.
- Zone and service choices that looked fine in May. Ground residential and economy products are where peak demand fees compound across volume. That is the ShipScience point Supply Chain Dive flagged on FedEx’s residential and Ground Economy jumps, and the same calendar pressure hits every major parcel option.
- Split inventory reality. Some of your SKUs belong in FBA for Prime speed. Some belong in a West Coast 3PL for DTC, returns, kitting, or overflow. Peak is when that split needs to be intentional, not accidental. We already wrote about Amazon’s FBA peak storage window starting October 1 and peak fulfillment from October 15 — different fee stack, same season. See Amazon peak storage starts October 1.
If you are still shipping from a garage, spare room, or a mailbox-style counter operation, this post is not for you. If you are trying to protect contribution margin while Q4 volume rises, packaging and warehouse process are the levers you control this month.
What to do in the next two weeks
Do the boring work before October 25, not during Black Friday week.
- Audit your top 20 SKUs by shipped volume and by cubic inches. Note length, width, height, weight, and whether the finished pack triggers Additional Handling or Large Package rules on the carriers you actually use. Fix cartonization where a smaller mailer or a tighter box is honest, not cosmetic.
- Separate “must stay in FBA” from “should live at a 3PL.” Slow, bulky, or DTC-primary units that sit in FBA pay peak storage and still may not help Prime conversion. Removals and rework take time — start before the October storage snapshot if that is your plan.
- Ask your warehouse how they rate-shop and pack. Negotiated USPS / UPS / FedEx access helps, but only if the pack-out is clean. A 3PL that cannot tell you how a SKU ships when dim weight flips is guessing with your margin.
- Model one ugly week. Take your actual mid-November order count, apply the published per-package peak layer for the carrier you expect to use, and add a sensitivity for oversized or additional-handling share. If that number makes you flinch, change the pack or the channel mix now.
At ShipDepot in Palmdale we run ecommerce and Shopify fulfillment for brands that need pick/pack, inventory visibility, and West Coast outbound without pretending we have a warehouse at the Ports of LA or Long Beach. We also handle Amazon removals and FBA prep when the inventory needs a different home than Amazon’s network. Peak is when those two lanes should talk to each other.
