These two letters indicate that the pallet is debarked according to IPPC regulations/stamps. Many pallets have this stamp. It does not matter if your pallet has this stamp or not. Many pallets do not have it. \newline % Row Count 7 (+ 5)
The process of "debarking" wood is to remove the bark (rough outer layers of wood) using a cutting tool or a planer, and the pallet wood remains untreated. This procedure is done to allow for a more thorough treatment of wood before being approved for transport (aside from smoothing the wood). Pallets marked with the letters DB only are chemical-free and safe to use. Newer pallets no longer require this stamp by the IPPC regulations, as most modern wood treatment procedures require "debarking" as a standard part of their process.% Row Count 18 (+ 11)

This coding system is a means to control warping, fungal growth, and other quality features. The kilns or ovens used to dry the wood do not necessarily reach the sustained temperature of 133 degrees Fahrenheit (56 Celsius) that would qualify as heat treated.  Many lumber mills are processing their timber to meet the heat treatment requirements; thus you will see "KD-HT" incorporated in the wood grade stamp.% Row Count 11 (+ 11)
