Hmm, I don't know. 8.5.1 clearly establishes that you need to be certified in order to buy them, but after that it gets muddy. Yes, as written, only motors sold from the manufacturer to a certified user gets logged, but if motor dealers are considered an agent of the manufacturer, they may inherit the manufacturer's restrictions.
I'd have to ask a lawyer on that one.
Maybe this is why TRA doesn't allow the sale of EX motors for profit.
The reason the TRA doesn't allow the sale of EX motors, is it is against the regulations in NFPA 1125 and the DOT. EX motors have no "EX" number which verified the DOT has tested the EX motor.
An EX number, preceded by the prefix "EX–", is issued and used by the Department of Transportation (DOT) to identify an explosive which has been tested and classified by DOT. See U.S. Department of Transportation regulations at 49 CFR 171.8 and 49 CFR 173.56.
Even though the BATFE has conceded that APCP is not an explosive, each APCP propellant variation has to have an EX number assigned, and then assigned an explosives classification , like 1.3C or 1.4S,etc for shipping & transportation purposes.
EX motors, aren't tested by DOT hence they don't receive an EX number nor an explosives classification.
So how are EX motors legally transported?
And if you read the NFPA codes carefully, they state that their purpose is to prevent people from making to their own motors.
How does TRA reconcile that?
Now before you jump on my case, let me say that I'm all for research experimental rocketry.
I personally believe that if a person makes their own motors they should be able to sell them.
Perhaps only at TRA or yes, even NAR sanctioned events.sign a waiver from the seller and sell only to adults.
One of the major problems this country has is over regulation on just about everything.
