The ISO pallet standards are established by the International Organization for Standardization (ISO) to ensure uniformity in pallet dimensions, construction, and performance for global logistics and supply chains. The most widely recognized ISO pallet standards are part of ISO 6780, which specifies the principal dimensions for flat pallets used in international trade.
Key ISO Pallet Standards:
- ISO 6780:2003 – Flat pallets for intercontinental materials handling – Principal dimensions and tolerances
- Defines six main pallet sizes for global trade.
- Specifies tolerances for dimensions and performance.
- ISO 8611 (Parts 1-3) – Pallets for materials handling
- Part 1: Test methods – Defines durability and load capacity tests.
- Part 2: Performance requirements – Specifies maximum load limits.
- Part 3: Maximum working loads – Provides guidelines for safe usage.
- ISO 18334:2023 – Marking of pallets
- Standardizes pallet markings for traceability and compliance.
Common ISO Pallet Sizes:
| Pallet Type | Dimensions (mm) | Dimensions (inches) | Common Usage |
|---|---|---|---|
| ISO1 (EUR Pallet) | 1200 × 800 × 144 mm | 47.24 × 31.50 × 5.67 in | Europe, most common worldwide |
| ISO2 | 1200 × 1000 × 144 mm | 47.24 × 39.37 × 5.67 in | Asia, chemical industry |
| ISO3 (US Pallet) | 1219 × 1016 × 144 mm | 48 × 40 × 5.67 in | North America |
| ISO4 (EUR2 Pallet) | 1200 × 800 × 144 mm | 47.24 × 31.50 × 5.67 in | Similar to EUR but different construction |
| ISO5 | 1067 × 1067 mm | 42 × 42 in | Telecommunications, paint, drums |
| ISO6 (EUR3 Pallet) | 800 × 600 × 144 mm | 31.50 × 23.62 × 5.67 in | Retail, small shipments |
Key Features of ISO Pallets:
Interchangeability – Fits standard trucks, containers, and racking systems.
Load Capacity – Must meet ISO 8611 strength requirements (static, dynamic, racking loads).
Material Types – Wood (most common), plastic, metal, or composite.
Fork Entry – Must allow forklift access from at least two sides.
ISO vs. Regional Standards
- EUR Pallets (EPAL) follow ISO1 (1200×800 mm) but have additional quality certifications.
- US Standard (48×40 inches) aligns with ISO3 but is slightly different in exact dimensions.
- Asian Pallets (1100×1100 mm or 1200×1000 mm) often follow ISO2.
For full compliance, check ISO 6780 and ISO 8611 for testing and performance criteria.
