Costco pallet requirements are one of the least glamorous parts of a Costco launch, and one of the easiest to get wrong. A brand can win the buyer, pass its audit and finish a successful roadshow, then watch a truck get turned away because the pallet was the wrong type, too tall or overhanging. This guide covers what has been reported about Costco pallets, where the sources disagree or go quiet, and how to check your own setup.

Today is October 24, 2026. Please read the sourcing note before relying on any number below.

A note on sources. We did not find a Costco-published pallet specification that we could open. The figures come from two third-party articles: one from iGPS, a pallet-pooling company that sells plastic pallets (page published May 1, 2020 and last modified February 15, 2024, no author listed), and one from a packaging company dated June 23, 2026 (updated July 10, 2026) that says its numbers rest on “publicly available vendor compliance guidance” without citing a specific Costco document. Treat every figure as a starting point and confirm it with your Costco buyer or vendor compliance contact.

The Reported Pallet Specifications

Where the two sources agree:

Size: 48 x 40 inches, with no product overhang.
Height: no more than 58 inches for the complete load, including the pallet.
Weight: no more than 2,500 pounds for the total pallet load.

Additional details from the iGPS page:

Type: general-use block pallets. Stringer designs are reported not to qualify for general use.
Strength: loads under 750 pounds must support 1,500 pounds on the bottom layer, and loads over 750 pounds must withstand 2,500 pounds on the lowest layer.
Condition: pallets are checked on delivery for load support, soundness and floor-use serviceability, and must be dry and uncontaminated, or they can be rejected.
Pooling providers: iGPS, CHEP and PECO are listed as accepted, and others need case-by-case approval (the page gives pallets@costco.com for inquiries).

Additional details from the 2026 packaging article:

Double-stack and clamp resistance: both described as required, meaning the corrugated must hold up to side compression from mechanical clamping.
Labeling: Costco item number, UPC and country of origin on the unit and the pallet.
Delivery model: no-touch cross-dock, floor-ready.
Chargebacks: up to 2 percent of invoice value, with repeat violations possibly leading to item deletion. This appears only in a comparison table and is not sourced to a Costco document.

What We Could Not Verify

Wrap, stacking pattern and test methods are not specified in the iGPS page.
The claim that Costco is moving to a plastic-only pallet model is unsourced on the iGPS page, which also promotes plastic pallets. Weigh it accordingly.
The 2 percent chargeback and the item deletion language are unsourced.
Pallet requirements may differ by product category, as the packaging article itself says.
Nothing here tells you how your specific depot or warehouse applies the rules.

Why Pallets Are a Brand Strategy Issue

The pallet is part of your cost structure. Costco’s model depends on high volume and low handling, and your Costco margin is thin. A pallet that holds fewer cases than it could, a box that crushes under a clamp, or a rejected delivery all eat that margin. Pallet configuration also feeds your case pack, your carton strength and your freight cost, so it belongs in the same conversation as your packaging plan, not after it.

Your Costco Pallet Requirements Checklist

Ask Costco first. Get the current written pallet and delivery requirements from your buyer or compliance contact.
Measure a real pallet. Build one with real cartons and measure total height with the pallet, and weigh it.
Stay under 58 inches and 2,500 pounds unless Costco tells you differently.
Check for overhang. Cartons should sit within the 48 x 40 footprint.
Test carton strength. Ask your packaging supplier about stacking and clamp compression.
Confirm labels. Costco item number, UPC and country of origin where required.
Decide on a pallet source. If you use a pooling provider, confirm it is approved.
Keep pallets dry and clean. Wet or contaminated pallets can be rejected.
Run a trial shipment plan with your logistics provider before the first purchase order.
Recalculate your landed cost with the final pallet configuration.

Common Pallet Mistakes

Using a pallet that works for another retailer without checking Costco.
Building the pallet tall to save freight and breaking the height limit.
Weak cartons that crush under double-stacking or clamping.
Overhang from oversized cartons.
Skipping a written confirmation of the spec.
Learning about chargebacks after the first invoice.
