Isengard wouldn't need blasting powder from Rhûn when they can make their own from scratch thanks to the secrets of Númenor left in that tower. Mordor would need it, but even then, they would most likely get it as tribute from the enslaved Easterling empires. Also, if you supply Isengard, they would definitely keep you out at all costs, letting none but the Ainur and Eru himself seay them to think otherwise. There's nothi wrong with thinking of a later, more logical time.
