We order reagent grade from Fisher Scientific and mix it ourselves. We use it mostly for 5% nital solutions for metallography and 20% for macroetching.

Sure, nitric acid is a very dangerous and corrosive substance. Here in Brazil we have an ABNT (our local equivalent to ASTM) standard that rules the transportation of dangerous and flammable products. Giovanni S. Crisi Sao Paulo - Brazil
Thanks Prof. Crisi. You're exactly right. Because of these considerations, I was wondering if the suppliers previously mention can ship through the mail, or if pick-up is required.
