Can any number of individual propellent grains weighing a max 30 grams or less be shipped via the US Postal Service without a Haz Mat charge?

That's what I was told by Ken at Performance Hobbies. As long as any one grain doesn't exceed 30 grams, there is no hazmat fee, regardless of quantity. It specifies on his website which reloads and SU motors require hazmat, and which ones don't.
ALL CTI requires hazmat fee.
they are not approved for USPS shipment, i believe. They can go UPS, but they carge a 35.00 fee now.(ups not the vendors or cti)
thats the way i understand it... CTI did not get the exemption for USPS shipments.
AT 29mm High power are the only hazmat free i know of. And some of them are not hazmat free.
(dumbed down)
the motor may not require hazmat, but no one got it approved to ship by USPS, so its shipped by UPS, which charges a fee for any rocket motor.
This is a guess, and only a guess, but could it be that CTI grains are in a plastic housing and AT grains are packed loose in a bag?
I believe how it's packaged plays into whether or not USPS will allow it to be shipped or not.
I know it affects DOT requirements.

With money to be made, you'd think any problems would be worked until corrected.
Keep in mind that changing the packaging would require changing their instructions, packaging, and who knows what else?
The question is how that will compare to the impact on sales. That's something I cannot even begin to hazard a guess on.

No. Not unless all the following requirements are met.Can any number of individual propellent grains weighing a max 30 grams or less be shipped via the US Postal Service without a Haz Mat charge?
AeroTech calls them "bifurcated" reloads, I believe. The F40W reload for the RMS 29/40-120 still features a grain that is similar in size to the old G64 reloads: one long propellant slug. It is a wonderful reload but if ordered online it incurs a Hazmat fee, which is a notorious hassle for that popular MPR motor in particular. Heck, even the black powder Estes E9 must be shipped by common carrier and will require payment of the fee because each one contains 35.8 grams of propellant. The one saving grace is that you only pay one fee for an entire box, so if you order in bulk the cost of the fee can be spread out over multiple motors.For example, the Aerotech G64W used to be a single 62.5 gram grain, and couldn't (or shouldn't - I don't remember always paying a fee) be shipped USPS.
Now, it is listed as 60 grams propellant weight and is split into two separate 30 gram grains which the user tapes together aligning the igniter slots.
The total impulse dropped from 120 to 112 NewtonSeconds, but they can be shipped USPS.
This is done with some of the red and green reloads as well.

Is CTI working on correcting their oversight anytime in the near future?
Is it a CTI problem? The USPS exemption is secured by the online retailer, not CTI the manufacturer. CTI reloads violate the "30 gram" rule, but to change that CTI would have to change the company from the business model down to the packaging. They built their business on being the easy reload, one piece, screw it in, fly it, screw it out, throw it away. I can't see them changing that
Another thing to bear in mind, CTI isn't even an American company. When it ships to vendors it is via Canadian post and could go to any country in which they have distributors each of which has their own shipping regulations.

bradycros said:In what manner is this information useful to USA consumers that dislike paying Haz Mat fees for low and mid powerd reloads.
"Change the company", I hardly think so.
It's black powder, not Pyrodex(R), but it doesn't change anything.I believe many of the CTI reloads use a pyrodex pellet to aid ignition. That might change things, compared to other reloads.
