Treated pallets are marked with the International Plant Protection Convention logo and letters indicating what type of treatment was used. Pallets with “MB” in the logo have been fumigated with methyl bromide, a poisonous, ozone-depleting gas that has been phased out for most agricultural uses. Pallets marked “MB” should never be used for gardening or fuel, while those with the letters “HT” (shown below) were heat treated or kiln dried and are safe to reuse.
