These bugs belong to the family Aradidae, the “flat bugs”.  Aradids feed on fungus and are not considered to be agricultural pests.

These were found on wood material (pallets etc.) at Andersen Airforce Base by USDA APHIS inspectors. This material came from the Naval Base and it was being shipped to Hawaii. The wood also contained termites and it was fumigated before leaving Guam.
