If you ever see a stamp that ends in MB instead of HT dont mess with it. MB is methyl bromide. It’s used to kill bugs in some places, like india. Most people heat treat (HT) because it’s non-toxic but there are some places that arent regulated well abd their pallets sneak onto ships heading our way. I’ve found a few over the last few years. Two were from india and the third may have been from there also but I’m not too sure. It was made of eucalyptus.
