The GMA pallet, codified by the Grocery Manufacturers Association, became the dominant 48x40 pallet specification in US commerce. This article covers its dimensions, construction, and supply chain role.
Origin of the GMA Pallet
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.
The GMA pallet originated from member-driven specifications of the Grocery Manufacturers Association (now CBA) in the 1960s, designed to standardize US grocery distribution at a single 48x40 inch dimension. The standard reduced supply chain friction by aligning pallet, truck trailer, and warehouse rack systems around a common pallet footprint.
GMA Pallet Construction
A standard GMA pallet has 7 top deck boards (5/8 inch thick), 5 bottom deck boards, and 3 stringers (1-1/2 inch thick, with 9-inch fork notches). The construction is documented in the NWPCA Uniform Standard. Total pallet weight typically ranges 30-40 pounds for hardwood mix construction.
Performance Characteristics
GMA pallets tested per ASTM D1185 typically support: 4,600 pounds static load, 2,800 pounds dynamic load, and 2,800 pounds racked load. Performance varies with wood species, fastener pattern, and deck-board count.
Retailer Receiving Compliance
Major US retailers - members of Retail Industry Leaders Association - have GMA-aligned receiving specifications. Walmart, Target, Costco, Home Depot, Lowe's, and similar receiving DCs explicitly require GMA-compliant pallets at inbound. Non-conforming pallets may be rejected, charged-back, or downgraded.
GMA vs Other Specs
While GMA is dominant in US grocery and consumer goods, alternative specs include: 42x42 (chemical drum), 48x48 (beverage), 36x36 (retail display), and 60x40 (international). Per MHI guidance, applications outside the GMA dominant flow benefit from custom specs that match unit-load geometry.
