Interdasting….I’ve seen a lot pallets,unless blue ones are for specific things..you don’t see them very often..those appear to be blue. The ones on the ship are also blue on the sides… intercepted cargo?
Did a little digging…
Here’s what the colors mean.
There are four main pallet pool companies in the world that you can differentiate by the color:
Red pallets: pool LPR (La Palette Rouge from Europe)
Red pallets: pool PECO (The Pallet Exchange Company from the USA)
Blue pallets: pool CHEP (Commonwealth Handling Equipment Pool from Australia)
Brown pallets: pool IPP (IPP Logipal from Europe)
Note: No chemical treatments or hazardous materials are used on PECO pallets (Red Pallets), and all lumber products used to construct and repair PECO pallets receive regular testing by an independent third party inspector. You can find more information at PECO Pallet. So, the red pallets from PECO should be safe to use for your DIY project.
