The ATF is on a bit of a hit streak when it comes to random reclassifications. First they arbitrarily and capriciously changed their collective mind on the pistol stabilizing brace. Then they tried to ban M855 ammunition by branding it as “armor piercing.” Now it seems that they are turning their gaze upon some of the less common items and applying their similarly capricious thought processes. The latest targets are types of projectiles which can be fired from 40mm grenade launchers, specifically parachute flares and chalk practice rounds. And their ruling could soon be expanded to include all ammunition bigger than 1/2 inch in diameter . . .
A thread on ARFCOM started it all, with the OP stating that they had been contacted by the ATF to turn in their recently purchased flare rounds. It is worth noting that these rounds had been previously classified by the ATF as non-explosives, but in this world of ever-changing definitions it seems that they have reversed themselves on that take.
