Pallets are an essential component of the global supply chain, facilitating the storage, handling, and transportation of goods. While they might seem like simple wooden or plastic platforms, the world of pallets is much more complex and varied than it first appears. Understanding the terminology associated with pallets can help consumers make informed decisions, whether they are purchasing pallets for business use, recycling them, or simply trying to navigate the logistics world. In this comprehensive guide, we’ll explore the most common pallet-related terms every consumer should know.
1. Pallet
At its core, a pallet is a flat structure that provides a stable base for stacking, storing, and transporting goods. They are typically made from wood, plastic, or metal and are designed to be lifted by forklifts, pallet jacks, or other handling equipment. Pallets are ubiquitous in warehouses, factories, and shipping centers around the world.
2. Standard Pallet Sizes
Pallets come in various sizes, but some dimensions are more common than others:
- 48×40 Pallet: Often referred to as the “GMA Pallet,” this is the most common pallet size in North America. It measures 48 inches by 40 inches and is widely used in the grocery and retail industries.
- 1200×1000 mm Pallet: Commonly used in Europe and Asia, this pallet size is equivalent to 47.24 inches by 39.37 inches.
- ISO Pallet Sizes: The International Organization for Standardization (ISO) recognizes six standard pallet dimensions to accommodate global shipping needs.
3. Block Pallet
Block pallets are built with blocks between the top and bottom deckboards, providing a strong and durable structure. They are four-way entry pallets, meaning they can be lifted from all four sides by forklifts and pallet jacks. This design offers more flexibility in handling and is often preferred for heavy loads.
4. Stringer Pallet
Stringer pallets, also known as “two-way entry” pallets, use stringers (lengthwise supports) to provide structure. Unlike block pallets, stringer pallets can typically only be lifted from two sides unless they have notches cut into the stringers, allowing for four-way entry.
5. Deckboards
Deckboards are the horizontal components on the top and bottom of the pallet that provide the surface area for supporting goods. They can be solid, slatted, or spaced, depending on the pallet’s design and intended use.
6. Pallet Jack
A pallet jack is a manual or powered tool used to lift and move pallets. Manual pallet jacks rely on human effort, while electric or powered pallet jacks use a battery-operated motor. They are commonly used in warehouses and retail environments for moving pallets over short distances.
7. Forklift
A forklift is a powered industrial truck used to lift and move materials over short distances. Forklifts are essential for handling pallets in warehouses, manufacturing facilities, and shipping yards. They come in various sizes and capacities, depending on the weight and size of the pallets they need to move.
8. Pallet Racking
Pallet racking is a storage system designed to hold pallets in an organized and efficient manner. It maximizes vertical space in warehouses and allows for easy access to pallets by forklifts. Common types of pallet racking include selective racking, drive-in racking, and push-back racking.
9. Load Capacity
Load capacity refers to the maximum weight a pallet can safely support. It is a crucial factor in selecting the right pallet for a particular application. Overloading a pallet can lead to structural failure and accidents.
10. Pallet Pooling
Pallet pooling is a system in which pallets are shared among multiple users, typically in a closed-loop supply chain. Instead of purchasing and managing their pallets, companies rent or lease pallets from a pooling provider, who handles the maintenance, repair, and redistribution of the pallets. This system can reduce costs and environmental impact.
11. Heat Treatment (HT)
Heat treatment is a process used to sterilize wooden pallets to prevent the spread of pests and diseases across borders. The International Standards for Phytosanitary Measures No. 15 (ISPM 15) require that wooden pallets used in international shipping be heat-treated and marked with an official stamp. This process involves heating the wood to a specific temperature for a set period, effectively killing any pests.
12. Kiln Drying
Kiln drying is a process used to reduce the moisture content of wooden pallets. By drying the wood in a kiln, manufacturers can prevent mold growth, improve the strength and stability of the pallet, and reduce the weight of the pallet. Kiln-dried pallets are often preferred in industries where hygiene is a concern, such as food and pharmaceuticals.
13. Recycled Pallets
Recycled pallets are those that have been used, repaired, and resold. They are a cost-effective and environmentally friendly option for businesses looking to reduce their carbon footprint. Recycled pallets are often as strong and durable as new ones, making them a popular choice in many industries.
14. Custom Pallets
Custom pallets are designed and manufactured to meet specific requirements that standard pallets cannot fulfill. This might include unique dimensions, specialized materials, or specific load capacities. Custom pallets are common in industries with unique products or shipping needs.
15. Pallet Grades
Pallet grades refer to the condition and quality of recycled pallets:
- Grade A Pallets: Also known as “premium” or “first-grade” pallets, these are in excellent condition with minimal wear and tear. They are typically used for retail or food-grade applications.
- Grade B Pallets: These pallets may have more signs of wear and repair but are still functional and safe. They are often used in industrial applications where aesthetics are less important.
- Grade C Pallets: These are the lowest grade of pallets, often heavily repaired or showing significant wear. They are typically used for one-way shipping or for heavy-duty industrial use.
16. Nestable Pallets
Nestable pallets are designed to stack inside one another when not in use, saving space in storage and transportation. They are often made from plastic and are ideal for industries where space efficiency is critical.
17. Stackable Pallets
Stackable pallets are designed to stack on top of one another when loaded with goods. This design allows for efficient use of vertical space in warehouses and during transportation.
18. Plastic Pallets
Plastic pallets are an alternative to traditional wooden pallets. They are lightweight, durable, and resistant to moisture and chemicals. Plastic pallets are often used in industries where hygiene is a concern or where pallets are reused frequently.
19. Metal Pallets
Metal pallets, typically made from steel or aluminum, are used in applications that require high durability and strength. They are often used in the automotive, aerospace, and heavy machinery industries. Metal pallets are resistant to extreme conditions and can support very heavy loads.
20. Pallet Recycling
Pallet recycling involves refurbishing and reusing pallets that are no longer fit for their original purpose. This can include repairing broken boards, replacing damaged stringers, or dismantling the pallet to use the wood for other purposes. Recycling pallets reduces waste and conserves resources.
21. Pallet Repair
Pallet repair involves fixing damaged pallets to extend their lifespan. This can include replacing broken boards, reinforcing weak areas, and ensuring the pallet is safe for use. Many companies prefer to repair pallets rather than purchase new ones, as it is more cost-effective and environmentally friendly.
22. One-Way Pallet
A one-way pallet is designed for a single use, typically for shipping goods from one location to another. These pallets are often made from low-cost materials and are not intended to be returned or reused.
23. Two-Way Pallet
A two-way pallet can only be lifted from two opposite sides, typically the front and back. This design limits the handling flexibility but can be sufficient for many applications.
24. Four-Way Pallet
A four-way pallet can be lifted from all four sides, offering greater handling flexibility and ease of use in tight spaces. This design is common in block pallets and some stringer pallets with notches.
25. Pallet Rental
Pallet rental is a service where companies lease pallets instead of purchasing them outright. This can be a cost-effective option for businesses that do not want to invest in owning and maintaining a large pallet inventory.
26. Pallet Exchange
Pallet exchange is a system where pallets are exchanged at the point of delivery. For example, when a shipment arrives at a destination, the receiving party provides an equal number of empty pallets in exchange for the loaded ones. This system helps maintain a balanced pallet inventory and reduces the need for purchasing new pallets.
27. EPAL (European Pallet Association)
EPAL is a certification body that sets standards for the production and repair of Euro pallets, ensuring they meet specific quality and safety requirements. EPAL pallets are widely used in Europe and are recognized for their durability and reliability.
28. CHEP

They provide pallets and containers to companies worldwide, managing the logistics of pallet distribution, retrieval, and maintenance. CHEP pallets are known for their quality and consistency, making them a popular choice for businesses of all sizes.
29. Palletizing
Palletizing is the process of stacking and securing goods on a pallet for transport or storage. This can be done manually or with the help of automated machinery. Proper palletizing ensures that goods are stable and protected during transit.
30. Shrink Wrapping
Shrink wrapping involves covering a palletized load with plastic film and then applying heat to shrink the film, creating a tight seal around the goods. This helps protect the load from moisture, dust, and damage during shipping.
31. Stretch Wrapping
Stretch wrapping is similar to shrink wrapping but does not involve heat. Instead, a stretchable plastic film is wrapped tightly around the palletized load, securing the goods in place. Stretch wrapping is commonly used in warehouses and shipping centers.
32. Pallet Tags
Pallet tags are labels or markers attached to pallets to identify their contents, destination, or ownership. They can include barcodes, RFID chips, or printed information and are essential for tracking and managing pallets in the supply chain.
33. Pallet Dispenser
A pallet dispenser is a machine that automatically dispenses pallets one at a time, reducing the need for manual handling. This equipment is commonly used in automated warehouses and production lines to improve efficiency and safety.
34. Load Securing
Load securing refers to the methods used to stabilize and secure goods on a pallet during transport. This can include strapping, stretch wrapping, shrink wrapping, and the use of corner protectors or load bars. Proper load securing is critical to preventing damage and ensuring the safety of the goods.
35. Pallets in E-commerce
In the e-commerce industry, pallets play a crucial role in the fulfillment and distribution process. With the rise of online shopping, the demand for efficient palletization and pallet management has increased.
