Pallet guides

Eight short guides, each answering one question a dock lead asks, with the answer in the first sentence and the source at the bottom.

How these are written

Each guide answers its question first and then explains. Claims about standards or rules link their source and show the date they were last reviewed. Where a number comes from a calculation, the guide shows the working. Where something is not known, the guide says so rather than guessing.

How the guides are checked

Each guide ends with its sources and the date they were read. Where a figure comes from a vendor, it is worded as the vendor's claim. Where sources disagree, the guide gives the range. If you spot a number that no longer holds, tell us through the request page and name the guide.

What the guides do not cover

Prices, legal advice and contracts. The guides explain the pallets, the sizes and the rules in plain terms. For a contract or a compliance question, consult the right professional.

Updates

Guides are reviewed on the date shown at the bottom of each page.

New to pallets? Read the repairs guide, then the weight guide. Shipping abroad? Read the stamp guide and the Canada guide. Packing a trailer? Read the trailer guide. Worried about damp wood? The mold guide covers storage, airflow and warning signs, with a moisture line to stay under.
