I dunno, if I was looking to get someone in shit sending them a large amount of illegal stuff marked as explosives would be one hell of a way to do it. That chemical name just doesn't seem like some random ass thing to mark down, like amino or other like Tanuki mentioned.
It seems like it would always bring additional scrutiny on the shipper too. Of course, a chemical company could manufacture pentaerythritol for legitimate pharmaceutical uses. But not so good if they're willing to ship bulk quantities to any individual who wants some.
