How to Inspect Pallets: A Step-by-Step Guide

Step one is the top deck inspection. Examine the top surface of the pallet for broken, cracked, or missing deck boards. Check for boards that are loose or have shifted out of position. Look for protruding nails or fasteners that could snag packaging or injure handlers. Verify that the gap between deck boards does not exceed the maximum allowed by your specification (typically 3/4 inch for general use). Check for surface contamination including oil stains, chemical residue, mold growth, unusual odors, or evidence of pest activity such as bore holes or sawdust. Any pallet with a missing or broken top deck board in a load-bearing position should be rejected.

Step two is the stringer or block inspection. For stringer pallets, examine each stringer for cracks, splits, or breaks. A cracked stringer compromises the pallet's structural integrity and is the most common cause of pallet failure under load. Pay particular attention to the areas around notches, where stress concentrations make cracks more likely. For block pallets, check that all blocks are intact, properly attached, and free from splits or crushing. Push laterally on the pallet to check for excessive looseness in the joints, which indicates that fasteners have weakened and the pallet may not hold together during handling.

Step three is the bottom deck and overall structure inspection. Flip or tilt the pallet to examine the bottom deck boards for damage, and verify that the pallet sits flat on a level surface without rocking or wobbling. Check for warping, twisting, or bowing that could prevent stable stacking or create instability in racking systems. Verify that all components are securely fastened and that no unauthorized repairs have been made using improper materials or methods. If the pallet is required to be heat-treated, confirm that a valid IPPC stamp is present and legible.
