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.

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 |

| 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) | Typically max 60 inches total | Allows forklift placement in warehouse racks; confirm with your buyer |

| 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 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 |

| 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 (market rate-2.50 per pallet per issue), rental fees (market rate-0.45/pallet/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) | current market price per pallet |
| Damaged pallet (broken boards, split stringer) | current market price per pallet |
| Excessive overhang (>1 inch per side) | current market price per pallet |
| Pallet height exceeds specification | current market price per pallet |
| Chemical contamination / odor | Load rejection; product quarantine at supplier cost |
| MB-stamped pallet for food/organic | Load rejection + potential account flag |

Frequently Asked Questions
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 (market rate-2.50 per issue, plus monthly 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.
