The classes in one line each
- New: unused, light, chamber-dried to a maximum of 22% moisture.
- Class A: used, mainly light, no adhesions beyond residue, no twisted blocks.
- Class B: used, mainly dark, otherwise similar structural criteria.
- Class C: heavily used; labels and tape allowed, blocks may protrude by up to about 1 cm.
- Not fit for use: any disqualifying defect.
Machine handling
EPAL's poster marks new, A and B as suitable for machines, conveyors and high-bay racking; C is not marked that way.
Status
The poster we use is EPAL's 08/2023 edition. It says the classification is a recommendation; without an agreement the Terms of Exchange apply, under which new and used pallets in classes A, B and C are exchangeable without restriction. Our grade pages give the full criteria with sources.
