Quoted from phil-lee:This may sound crazy, but ship with Carriers that have a Hazardous Materials endorsement and regularly ship chemicals.
Here is another idea....how about we have the distributors slap a sticker on the boxes labeling them as hazardous materials? Might raise the price a bit but they just might be a little more careful. Sure it is a little fib, well, maybe not in California. I do feel for you. Each time I have a pin delivered I give a sigh of relief when I see the box unscathed. Good luck to ya.
