What’s the difference between 1.4G and 1.3G fireworks, and do I need a different license?

I keep seeing fireworks labeled 1.4G and some labeled 1.3G. I get that 1.3 is “professional” but what’s the actual difference in the product itself? Like is it just the amount of explosive material or is there something else going on?

Also, if I’m a hobbyist who wants to get into 1.3G stuff ??what kind of license or permit do I actually need? I’ve heard conflicting things. Some people say you need a federal permit, others say it depends on the state.

Appreciate any clarification. Getting kinda confused with all the different classifications.

Great question. The difference is mainly the net explosive weight and how they’re classified by DOT/ATF. 1.4G is consumer grade ??less explosive content, stricter limits on how much powder per shell. 1.3G is for professional use ??bigger payloads, more flash powder.

For the license part ??you’ll need an ATF Type 20 FEL (Federal Explosives License) for 1.3G. Plus most states require additional permits. It’s not impossible to get but it takes time and paperwork.

There’s some good info in the Rules section here if you search around ??I remember a thread that went deep into the ATF requirements.
