CP Chemical Pallet Dimensions: CP1 to CP9 Guide
CP chemical pallet dimensions play an essential role in securing operations throughout the chemical and petrochemical industries, which impose some of the world's strictest safety and logistics requirements.
Handling drums containing toxic chemicals, big bags filled with volatile powders or industrial octabins requires load carriers capable of minimising the risk of structural failure. The CP (Chemical Pallet) standard was developed to meet these demanding requirements.
Far more than a simple wooden platform, each chemical pallet model follows specific technical specifications adapted to a particular type of industrial packaging.
This comprehensive guide explains the dimensions, technical characteristics and load capacities of the nine CP pallet formats, helping you secure your shipments while optimising packaging costs.
CP Pallet Standards: Specifications for the Chemical Industry
Before examining the different dimensions, it is essential to understand the technical and regulatory framework governing these load carriers.
Standardisation is a key factor in ensuring smooth international supply chain operations and protecting logistics personnel.
The APME Specification: Origins and Technical Requirements
The CP pallet standard was developed in the early 1990s by the APME (Association of Plastics Manufacturers in Europe), whose industry representation is now associated with PlasticsEurope .
The objective was clear: to replace the numerous inconsistent pallet formats with nine standardised models, numbered from CP1 to CP9.
This harmonisation covers four essential areas of the technical specifications:
- Wood species: typically pine, spruce or poplar, according to the applicable manufacturing specifications.
- Board thickness: precisely defined dimensions for the wooden deck and its components.
- Nails: specified types of ring-shank or other approved fastening nails.
- Chamfered runners: bevelled lower boards designed to facilitate the entry of pallet truck and forklift forks.
Wooden Chemical Pallets: Export Treatment Requirements
As a substantial proportion of chemical products is traded internationally, wooden chemical pallets must be suitable for the customs and phytosanitary requirements of their destination markets.
Where ISPM 15 applies, wooden CP pallets must undergo an approved phytosanitary treatment and carry the corresponding official marking.
For conventional heat treatment (HT), the wood must reach a temperature of at least 56 °C for 30 continuous minutes throughout its entire profile, including its core.
The applicable requirements must be checked against the rules of the importing country. To secure international shipments and reduce the risk of customs delays, consult our guide to ISPM 15 pallet compliance and export regulations .
CP1 to CP9 Chemical Pallets: Complete Dimensions Comparison Table
The CP range consists of nine distinct formats that differ not only in their overall dimensions, but also in the construction of their bases.
Depending on the model, the pallet may feature three conventional bottom runners or a reinforced perimeter frame that distributes loads more effectively across the floor.
| Model | Dimensions (L × W, mm) | Base Structure | Main Chemical Industry Application |
|---|---|---|---|
| CP1 | 1000 × 1200 | 3 bottom runners | Bags, cartons and lightweight big bags. |
| CP2 | 800 × 1200 | 3 bottom runners | Boxes, cartons and drums. Footprint equivalent to an EPAL Euro pallet. |
| CP3 | 1140 × 1140 | 3 bottom runners | Drums, big bags and octabins. Suitable for efficient maritime container loading. |
| CP4 | 1100 × 1300 | 3 bottom runners | Bags containing bulk chemical products. |
| CP5 | 760 × 1140 | 3 bottom runners | Cartons and smaller shipments in freight containers. |
| CP6 | 1200 × 1000 | Perimeter base frame | Bagged products and intensive stacking. Reinforced base compared with CP1. |
| CP7 | 1300 × 1100 | Perimeter base frame | Bagged products. Reinforced base compared with CP4. |
| CP8 | 1140 × 1140 | Perimeter frame with discharge opening | Big bags fitted with a bottom-discharge system. |
| CP9 | 1140 × 1140 | Perimeter base frame | Drums, octabins and big bags. Reinforced base compared with CP3. |
Technical Specifications by CP Pallet Model: Dimensions and Applications
Although the previous comparison table provides an overall view of the different CP pallet formats, it is essential to examine the specific characteristics of each load carrier in detail.
The choice of pallet depends not only on its external dimensions, but above all on the construction of its base, which determines its stacking capability and its behaviour on automated conveyor systems.
CP1 Pallet Dimensions and CP3 Pallet Format: Versatile Standards
The CP1 pallet dimensions (1000 × 1200 mm) represent one of the most versatile and widely used formats in Europe, comparable to the conventional industrial wooden pallet .
Equipped with three bottom runners, the CP1 is ideal for packaging and transporting light to medium-weight loads, including bags of plastic granules, cartons and smaller chemical drums.
Its deck overhang provides effective retention of stretch film during pallet wrapping operations.
The CP3 pallet format (1140 × 1140 mm), on the other hand, has a perfectly square footprint.
This geometry is not accidental: it was calculated to optimise the use of space inside ISO maritime shipping containers, reducing the need for additional load-securing materials.
The CP3 is a key reference format for accommodating exactly four standardised 200-litre metal drums or a large-capacity octabin.
CP6 Pallet Size and CP4/CP7 Characteristics: Specialised Formats
The CP4 (1100 × 1300 mm) and CP7 (1300 × 1100 mm) models share the same overall footprint dimensions, but differ in the orientation of their boards and the construction of their bases.
The technical characteristics of CP4 and CP7 pallets primarily address the needs of the polymer industry, particularly the transport of bagged products.
Their elongated rectangular footprint prevents bags from extending beyond the edge of the pallet, helping to avoid tearing during forklift handling.
The CP6 pallet (1200 × 1000 mm) provides the same supporting area as the CP1, but differs in one major structural feature: a perimeter frame at its base.
This base consists of intersecting runners that form a closed supporting frame.
The perimeter frame distributes the weight more evenly across the supporting surface, making the CP6 particularly suitable for stacking multiple pallets of bagged products without crushing the lower layers, provided the load and stacking limits are respected.
CP8 and CP9 Pallet Dimensions: Load Carriers for Heavy Containers
Packaging engineering reaches a particularly advanced level with the CP8 and CP9 models.
The CP8 pallet measures 1140 × 1140 mm and has a unique visual characteristic: a large central opening built into its deck.
This opening is specifically designed to enable bottom discharge from big bags, also known as flexible intermediate bulk containers (FIBCs).
The product can therefore be emptied through the bottom of the container without requiring the load to be lifted or handled dangerously above a discharge hopper.
Finally, the CP9 pallet (1140 × 1140 mm) is the heavy-duty, reinforced version of the CP3.
By replacing the three conventional runners with a particularly robust perimeter frame, the CP9 significantly improves the security of maritime transport operations.
It also provides enhanced stacking stability for heavy drums and octabins filled with dense powders.
Handling and Load Resistance: CP Pallet Weight and Payload
In the chemical industry, pallet failure can result in toxic spills, production line shutdowns and major safety risks for operators.
The structural strength of CP pallet models is therefore a non-negotiable selection criterion.
CP Pallet Load Resistance: Ensuring Safe Storage
The standardised construction of these load carriers has a direct impact on their own weight.
The empty weight of a CP pallet varies significantly depending on the model. It can range from approximately 15 kg for a lightweight CP1 to around 25 to 30 kg for models equipped with a perimeter frame, such as the CP7 or CP9.
This greater quantity of wood contributes to the strength and stability of the pallet during handling and storage.
In terms of load resistance, most CP pallet formats are designed to withstand dynamic loads, meaning loads handled on forklift forks, generally ranging from 1,000 to 1,500 kg.
Under static loading conditions, when resting on a suitable floor, the supported load can sometimes reach approximately twice the dynamic capacity, depending on the model and construction.
To understand how these technical capabilities compare with other pallet standards available on the market, consult our comparative guide covering the different types of wooden pallets and their logistics applications .

B2B Sourcing: Chemical Pallet Manufacturers and the Second-Hand Market
Sourcing standardised load-handling equipment is a strategic issue for buyers in the chemical industry.
A stock shortage affecting a specific pallet format can bring a bagging line to a standstill or delay a maritime shipment.
It is therefore essential to diversify supply sources while maintaining the highest possible quality and compliance requirements.
How to Select a Reliable Chemical Pallet Manufacturer
Working with a qualified chemical pallet manufacturer helps ensure that the supplied products meet the original APME (PlasticsEurope) specifications.
When carrying out your supplier audit, carefully verify the origin of the wood species used, the consistency of their moisture content, which affects both the empty weight and the mechanical strength of the pallet, and the presence of the required identification markings on the central wooden block.
This identification marking should include the CP logo, the manufacturer's identification code and the year of production, in accordance with the applicable CP specifications.
Used CP Pallets: An Economical and Environmentally Responsible Alternative
To reduce their carbon footprint and optimise packaging costs, many industrial businesses choose to purchase used CP pallets .
This second-hand market is particularly well established. However, purchasing refurbished chemical pallets requires several strict inspection checks.
- Mechanical integrity: no deck boards should be missing, and supporting blocks must not show cracks that could compromise safe stacking.
- Absence of contamination: pallets previously used to transport hazardous chemicals must be carefully inspected and, where appropriate, cleaned and assessed before reuse to prevent any cross-contamination with your products. Pallets with suspected hazardous residue should not be reused without appropriate safety clearance.
- Phytosanitary compliance: if your used wooden pallets are intended for export destinations where ISPM 15 applies, make sure the pallet has a valid and clearly legible phytosanitary mark, and that any repairs or alterations have not invalidated its compliance.
Managing your logistics operations requires reliable load carriers that are perfectly adapted to the density of your raw materials.
Whether you want to optimise maritime container loading using CP3 pallets or secure your big bags using reinforced CP9 pallets, tailored packaging audit support is essential for keeping your packaging budget under control.

FAQ
What Is the Main Difference
Between a CP1 and a CP6 Pallet?
Although they share exactly the same floor footprint, with the CP1 measuring 1000 × 1200 mm and the CP6 measuring 1200 × 1000 mm, the main difference lies underneath the pallet.
The CP1 has three conventional longitudinal runners, while the CP6 is fitted with a perimeter frame consisting of intersecting runners forming a closed supporting structure.
This design provides a significantly larger contact area with the supporting surface, making the CP6 particularly suitable for stacking heavy loads.
Can All Chemical Pallets
Be Safely Stacked?
CP chemical pallets are made from solid wood, and their construction can allow loaded units to be stacked, provided the pallet's rated capacity and load stability requirements are respected.
However, for particularly demanding stacking operations, especially those involving heavy bags or drums, models equipped with a perimeter frame are strongly recommended.
These include CP6, CP7, CP8 and CP9 pallets, whose reinforced bases distribute weight more evenly and help prevent the goods on the lower pallet from being crushed.
