Costco Wholesale is one of the most demanding retail buyers in the United States from a pallet compliance standpoint. Their warehouse-club format means pallets arrive in Costco locations fully loaded with product that is sold directly off the pallet on the warehouse floor - which means pallet appearance, structural integrity, and safety matter not just for logistics, but for the customer-facing retail experience. Suppliers who ship non-compliant pallets to Costco face stiff chargebacks, potential load rejections, and account flags that can affect future order allocations.

Get Costco-Ready Pallets →What Are Costco's Pallet Height Requirements?
A complete Costco load, pallet included, cannot exceed 58 inches in height, according to the iGPS summary of Costco pallet requirements. The same summary caps total pallet load weight at 2,500 pounds and calls for a 48 by 40 inch footprint with no product overhang. A pooled 48x40 block pallet is 5.56 inches tall on PECO's published spec, which leaves roughly 52 inches for product and cap sheet. Measure the loaded pallet after wrapping, and confirm current limits with your Costco buyer or pallets@costco.com, because iGPS notes Costco has planned changes to its guidelines.
Costco Pallet Specification (2026)
Pallet Lumber & Sawmill Operations
Stamped kiln-dried pallet lumber, bulk warehouse stock, dimensional yard inventory, raw softwood logs, and sawmill operations - the supply chain behind every custom and standard pallet we ship.
| Requirement | Specification | Notes |
|---|---|---|
| Pallet dimensions | 48 x 40 inches (GMA standard) | Non-standard sizes will be rejected at depot receiving |
| Pallet construction | Stringer or block pallet acceptable | Block pallets preferred for heavier or display merchandise |
| Pallet grade | Grade A minimum; new preferred for display items | Broken boards, split stringers, or loose blocks result in immediate chargeback |
| Wood treatment | HT (heat treated) or KD (kiln dried) only | MB-stamped pallets prohibited; CHEP pallets accepted at most depots |
| Load overhang | Max 1 inch per side | Costco is strict about overhang - product must stay within pallet footprint for floor display |
| Pallet height (loaded) | Max 58 inches, pallet included | Per the iGPS summary of Costco requirements; confirm with your buyer |
| Chemical contamination | Zero tolerance | Costco food buyers specifically audit for pallet odor and contamination |
| Pallet labels / markings | Pallet label placement per Costco Vendor Agreement | Label position on pallet corner; confirm in current vendor guide |
Display-Ready Pallet Requirements at Costco
Costco's warehouse-club format means many supplier products arrive on "display-ready pallets" - the pallet and its product shrink-wrap or display tray is placed directly on the warehouse floor for customer shopping. This creates additional requirements beyond standard retailer distribution:
- Pallet appearance matters: Costco members browse products on the pallet, so the pallet itself is visible. New or near-new Grade A pallets only - stained, patched, or clearly old pallets are not acceptable for display floor placement. Many Costco buyers specify new pallets for display-floor merchandise.
- Consistent deck board spacing: Display pallets need consistent, even deck board spacing to ensure the display tray or shrink-wrapped product sits level and stable. Avoid pallets with irregular or replaced board placement.
- No protruding nail heads: The bottom of the display sits directly on top deck boards - any raised nail head can puncture packaging. Nail heads must be flush or slightly recessed.
- Shrink-wrap compatibility: The pallet base must accept the bottom wrap layer of the display unit without snagging on rough edges or protruding fasteners. Smooth, clean top deck boards are essential.
- Maximum weight for display floor: Floor-stacked displays are limited by Costco safety rules (typically 3,000 lbs per display position). Confirm your loaded pallet weight with your buyer - very heavy loads may require direct delivery to floor-level placement by forklift only.
Costco Depot and Distribution Center Locations in Our Territory
Costco routes most inbound vendor shipments through regional depots before distribution to individual warehouse locations. Suppliers in FL, GA, NJ, MD, and DE route through these facilities:
| Depot / Location | States Served | Type | Notes for Suppliers |
|---|---|---|---|
| Morrow, GA (Atlanta area) | GA, AL, TN, SC, parts of FL | Full depot - grocery, perishables, hardlines | Primary entry for Southeast food and beverage suppliers; GFSI audit required |
| Alachua, FL (North FL) | North and Central FL | Grocery and perishables | Publix-dense market; food-grade pallet requirements strictly enforced |
| Doral, FL (Miami area) | South FL, Caribbean | Grocery, perishables, import | High produce volume; food-grade and ISPM-15 for import products |
| Robbinsville, NJ | NJ, NY, CT, DE | Full depot - all categories | Busiest East Coast Costco depot; pharma-adjacent supply chain requires Grade A documentation |
| Savage, MD (Baltimore area) | MD, VA, DC, parts of DE | Grocery and general merchandise | Government/defense corridor adjacency; documented Grade A strongly preferred |
Costco Food Safety and Organic Requirements
For food suppliers to Costco, pallet requirements overlap with food safety compliance in important ways:
| Category | Requirement | Documentation |
|---|---|---|
| Food products (general) | GMA Grade A, no contamination, HT or KD wood | Supplier conformance letter |
| Organic products | No MB-stamped pallets; KD or HT wood only | Wood treatment certification; no chemical history |
| Kirkland Signature (private label) | New pallets strongly preferred; Grade A minimum | Pallet spec on file with Costco buying team |
| Produce / fresh items | Food-grade certified; moisture <19%; no mold | Inspection documentation on supplier file |
| Pharmaceuticals / supplements | GDP-compliant; new block preferred | Batch documentation available on request |
CHEP Pallets at Costco: What Suppliers Need to Know
CHEP rental pallets (blue pallets) are accepted at Costco depots and are sometimes preferred at certain distribution channels. However, using CHEP has cost implications for the supplier:
- CHEP charges issue fees ($2.00 to $2.50 per pallet per issue), rental fees ($0.35 to $0.45 per pallet per month), and transfer fees when pallets move between locations.
- Once a CHEP pallet enters the Costco supply chain, it stays in the CHEP system - it will be returned to CHEP, not to you. Budget for replacement issue fees on every delivery.
- For display-floor merchandise specifically, many Costco buyers prefer new-looking pallets regardless of CHEP or own. A beat-up CHEP pallet on the display floor does not align with Costco's store experience standards.
- For most food and beverage suppliers who ship to Costco without a CHEP mandate, owned Grade A pallets cost significantly less over 12 months. Run your annual cost model before defaulting to CHEP.
Costco Chargeback Schedule for Non-Compliant Pallets
Costco enforces pallet compliance through chargebacks against the vendor account. Typical chargeback triggers (confirm current amounts with your vendor agreement, as Costco updates periodically):
| Violation | Typical Chargeback Range |
|---|---|
| Wrong pallet dimensions (not 48x40) | Set in your vendor agreement |
| Damaged pallet (broken boards, split stringer) | Set in your vendor agreement |
| Excessive overhang (>1 inch per side) | Set in your vendor agreement |
| Pallet height exceeds specification | Set in your vendor agreement |
| Chemical contamination / odor | Load rejection; product quarantine at supplier cost |
| MB-stamped pallet for food/organic | Load rejection + potential account flag |

Why this column does not carry dollar figures. Costco does not publish a pallet chargeback schedule. The amount is set in your individual vendor agreement and it changes, so any number printed here would be a guess dressed up as a rate. What we can give you is the channel benchmark: on our Whole Foods supplier guide the published band for pallet chargebacks is $15 to $75 per pallet, which is a different retailer's rate and is offered here only to size the exposure. As of August 2026 the practical rule for Costco vendors is that a size or grade defect is chargeable per pallet, while an MB stamp, contamination or odor is a rejection event where the real cost is the quarantined load, not the pallet.

Costco Pallet Requirements by Product Category
Costco's pallet standard tightens as the product moves from back-of-house grocery to the customer-visible warehouse floor. All food deliveries require Grade A GMA 48x40 stringer or block pallets stamped HT or KD, never MB. Kirkland Signature private label and display-floor merchandise push the bar up to new or near-new pallets. The matrix below consolidates the category rules Costco vendors are held to.
| Product category | Minimum pallet grade | Treatment / stamp | Key added rule |
|---|---|---|---|
| Dry grocery / standard CPG | Grade A GMA 48x40 (recycled acceptable if it meets spec) | HT or KD | No broken boards, split stringers, or protruding nails |
| Food and beverage | Grade A GMA 48x40 | HT or KD, never MB | Free of chemical staining and contamination for food contact |
| Organic (NOP certified) | Grade A GMA 48x40 | HT or KD stamped only (MB banned under NOP) | Treatment stamp must be legible on the pallet |
| Kirkland Signature private label | New or near-new strongly preferred | HT or KD | Buyer-visible brand standard; uniform appearance |
| Display-floor / pallet-display | New or high-grade Grade A (uniform, no patches or staining) | HT or KD | Even top deck, no protruding fasteners, overhang within 1 inch per side |
| Frozen / refrigerated | Grade A GMA 48x40, structurally sound for cold-chain racking | HT or KD | Confirm block vs stringer against the depot racking system |
Grade and treatment rules above reflect Costco vendor practice as of July 2026; always confirm current specifications with your assigned Costco buyer and depot.
One category sits outside the matrix above: imported goods that arrive on a metric footprint. Costco distribution centers work to the GMA 48x40 standard, so a container landing on 1200x1000 or EPAL Euro stock generally has to be transferred to GMA pallets at the port or a 3PL before it can be delivered to a Costco DC. The dimensional comparison, the EPAL certification question and how to plan that transfer are covered in our guide to metric pallets in the US.
Frequently Asked Questions
Total pallet load weight cannot exceed 2,500 pounds, per the iGPS summary of Costco requirements. The pallet itself is also rated by how heavy the load is: a pallet loaded with less than 750 pounds must handle 1,500 pounds of bottom layer weight, and one loaded with more than 750 pounds must withstand 2,500 pounds of bottom layer weight. Combine that weight cap with the 58 inch height limit when you build the pallet pattern, and confirm both with your buyer.
Costco accepts both CHEP rental pallets and vendor-owned pallets at most depots. They do not universally mandate CHEP the way some channels do. However, for display-floor merchandise, many Costco buyers prefer new or near-new pallets regardless of program. If your buyer has a CHEP preference, build the issue and rental fees ($2.00 to $2.50 per issue, plus $0.35 to $0.45 per pallet per month rental) into your logistics cost model before committing to CHEP as your default program.
Grade A GMA 48x40 stringer or block pallets are required for all food product deliveries to Costco. The pallet must be free of broken boards, split stringers, protruding nails, chemical contamination, and pest evidence. For organic products under NOP certification, pallets must be HT or KD stamped - never MB. For Kirkland Signature private label products, new pallets are strongly preferred. Grade A recycled pallets meeting all above criteria are generally acceptable for standard grocery and beverage items.
Yes. Display-floor pallets at Costco are customer-visible and directly affect the store experience. Costco buyers typically require new pallets or very high-quality Grade A (near-new, uniform, no visible patches or staining) for items placed directly on the warehouse floor for member shopping. Top deck boards must be even, smooth, and free of protruding fasteners. Load overhang must be within 1 inch per side of the pallet footprint. Check with your specific Costco buyer for current display-floor pallet specifications.
Costco typically allows no more than 1 inch of product overhang per side of the 48x40 pallet footprint. Overhang beyond this creates stability issues in the depot racking system and on the warehouse display floor, and is charged back to the vendor. Measure your loaded pallet before shrink-wrapping to confirm the product footprint stays within spec. If your product packaging naturally overhangs a 48x40 footprint, discuss with your buyer whether a larger custom pallet size or different stacking pattern is an option.
Yes. We supply Costco-compliant Grade A GMA pallets for vendor deliveries out of FL, GA, NJ, MD, and DE. We provide supplier conformance letters confirming pallet grade, species, and treatment type (HT/KD only, no MB). Our Grade A recycled supply is inspected before delivery and meets or exceeds Costco's structural requirements. Contact us with your weekly volume and primary depot destination - we set up standing orders for Costco vendors to ensure consistent compliance.
All Costco food deliveries require Grade A GMA 48x40 stringer or block pallets stamped HT or KD, never MB. Dry grocery accepts spec-compliant recycled Grade A. Organic (NOP certified) requires HT or KD only because methyl bromide is banned under NOP. Kirkland Signature private label and display-floor merchandise push the standard to new or near-new pallets with a uniform appearance, even top deck, no protruding fasteners, and overhang within 1 inch per side. Frozen and refrigerated loads need structurally sound Grade A confirmed against the depot racking system.
