Industry Resources & Standards

The pallet industry is governed by several international standards and trade organizations. Here are the key references every pallet buyer should know.

NWPCA

nwpca.com

National Wooden Pallet & Container Association

The primary trade association for the US wood packaging industry. Sets voluntary quality standards, provides industry data, and advocates for sustainable forestry practices. Their Pallet Design System (PDS) software is the industry standard for pallet engineering.

ISPM-15

ippc.int

International Standards for Phytosanitary Measures No. 15

The international regulation governing wood packaging materials in international trade. Requires heat treatment or fumigation of solid wood packaging to prevent the spread of invasive insects and plant diseases. Enforced by 180+ countries.

IPPC

ippc.int

International Plant Protection Convention

The United Nations body that developed ISPM-15 and oversees its global implementation. The IPPC logo on a pallet stamp certifies that the treatment facility is registered and audited by the national plant protection organization.

GMA

consumerbrandsassociation.org

Grocery Manufacturers Association

Established the 48x40-inch pallet as the US standard. Now known as the Consumer Brands Association. The GMA pallet specification defines dimensions, construction methods, and quality standards for pallets used in grocery and consumer goods distribution.

ISO 6780

iso.org

International Organization for Standardization

Defines the six standard pallet sizes recognized worldwide: 1219x1016mm (48x40"), 1000x1200mm (EUR), 1165x1165mm (AUS), 1067x1067mm (42x42"), 1100x1100mm (Asia), and 800x1200mm (EUR half). Essential reference for international shipping.

ASTM D1185

astm.org

ASTM International Pallet Testing Standard

Standard test methods for pallets and related structures. Defines testing procedures for compression, bending, impact, and vibration resistance. Used by engineers to validate custom pallet designs meet performance requirements.

Terminology

Pallet Industry Glossary

The pallet industry uses specialized terminology. Here is a comprehensive reference to help you communicate effectively with suppliers and logistics partners.

Block Pallet

A pallet that uses solid wood blocks at the corners and center to support the deck boards. Allows true 4-way forklift entry without notching. Standard in European logistics (EUR pallets).

Stringer Pallet

A pallet that uses long boards (stringers) running between the top and bottom deck boards. The most common pallet type in North America. Can be notched for 4-way entry.

GMA Pallet

The standard 48x40-inch pallet defined by the Grocery Manufacturers Association (now Consumer Brands Association). Accounts for approximately 30% of all new pallets produced in the US.

Dynamic Load

The maximum weight a pallet can safely support while in motion -- being lifted by a forklift or pallet jack. Always lower than static load rating due to additional forces during movement.

Static Load

The maximum weight a pallet can support while at rest on a flat surface. Typically 2x the dynamic load rating. Applies when pallets are floor-stacked in a warehouse.

Racking Load

The maximum weight a pallet can support when placed on warehouse racking beams with the center span unsupported. The most demanding load condition and always the lowest rating.

Deck Board

The horizontal boards that form the top and bottom surfaces of a pallet. Top deck boards support the load directly. Bottom deck boards (bottom deck) contact the floor or racking.

Chamfer

An angled cut on the bottom edge of a stringer or lead board that creates a tapered entry point for forklift forks. Reduces fork entry damage and makes handling easier.

Wing Pallet

A pallet where the deck boards extend beyond the stringers or blocks, creating overhanging wings. Used when loads are wider than the pallet base or for certain racking systems.

Flush Pallet

A pallet where deck boards are cut flush with the outer edge of the stringers or blocks. The most common configuration for standard pallets.

Notched Stringer

A stringer with rectangular cutouts that allow forklift forks to enter from the sides (perpendicular to the stringer direction), enabling partial 4-way entry on a stringer pallet.

ISPM-15

International Standards for Phytosanitary Measures No. 15. The global regulation requiring heat treatment or fumigation of wood packaging materials used in international trade.

Heat Treatment (HT)

A thermal process where the core temperature of wood is raised to 56 degrees Celsius for at least 30 minutes. Kills insects and pathogens. Required for ISPM-15 compliance.

Board Foot

A unit of lumber measurement equal to a volume of 1 foot x 1 foot x 1 inch (144 cubic inches). Used to calculate the amount of raw lumber in a pallet.

Pallet Pooling

A system where pallets are rented rather than purchased. Companies like CHEP (blue) and PECO (red) maintain pools of standardized pallets that circulate between users for a daily rental fee.

Closed-Loop System

A pallet management approach where pallets circulate between specific points in a supply chain and are returned to the shipper after delivery. Maximizes reuse and minimizes waste.

Dunnage

Blocking, bracing, and cushioning materials used to fill voids and stabilize loads on pallets, in containers, or on trailers. Includes airbags, foam, wood blocks, and corrugated dividers.

Unitizing

The process of consolidating multiple items into a single pallet load using stretch wrap, strapping, or other containment methods. Creates a stable, handleable unit for efficient transportation.
