Tannerite & Binary Explosive Targets — What You Need to Know Before You Buy
Tannerite is the brand name for the original binary explosive target — and the name that has become the generic term for the entire category. Binary targets consist of two chemical components: ammonium nitrate (an oxidizer) and aluminum powder (a fuel). Neither is explosive independently. Mixed together and struck by a high-velocity bullet traveling above approximately 2,000 feet per second, the combination produces a loud detonation and a visible cloud of vapor. No fire, no electricity, and no low-velocity impacts — including dropped targets, hammer strikes, and shotgun blasts — will detonate properly formulated binary targets.
The practical appeal is straightforward: instant, visible confirmation of a hit from long range without walking downrange. A target detonating at 200 yards provides immediate feedback that a conventional paper target cannot match. This makes binary targets popular for long-range practice, hunting zero confirmation, and recreational shooting.
Tannerite is not regulated by the ATF as sold — the separate components are not individually explosive and fall outside 27 CFR 555 in unmixed form. Once mixed, the user becomes the manufacturer of an explosive under federal law and must use the product immediately for personal, non-commercial target practice. Mixed product cannot be legally transported without a federal explosives license. Mix it, use it same session, done.
Several states and jurisdictions impose additional restrictions beyond federal law. California requires a permit in some circumstances. Maryland has enacted specific legislation targeting binary target components. Local burn bans, range policies, and county ordinances frequently restrict exploding targets regardless of state law.

Tannerite & Binary Target Frequently Asked Questions
What caliber do you need to shoot Tannerite?
Any high-velocity centerfire rifle cartridge traveling above approximately 2,000 feet per second at the target will detonate Tannerite. 5.56 NATO, .223 Rem, .308 Winchester, 6.5 Creedmoor, 7.62x39mm, and virtually all centerfire rifle calibers work reliably at appropriate distances. Pistol rounds, .22 LR, and shotgun ammunition typically do not travel fast enough to initiate detonation at safe shooting distances. For the full breakdown by caliber, see our guide to what caliber sets off Tannerite.
Is Tannerite legal to buy without a license?
Yes, in most states. Because the two components — ammonium nitrate and aluminum powder — are not individually explosive, Tannerite is not regulated as an explosive by the ATF when sold in unmixed form under 27 CFR 555. No federal license or permit is required to purchase, possess, or transport unmixed binary target components. Once mixed, federal law requires the product to be used immediately for personal, non-commercial target practice — the mixed product cannot be legally transported without a federal explosives license. Several states impose additional restrictions — always verify your state's laws before purchasing.
What is the minimum safe shooting distance for Tannerite?
The Tannerite brand's manufacturer guidelines specify minimum distances based on target weight: 100 yards minimum for half-pound and one-pound targets, 200 yards minimum for two-pound targets. Most Tannerite injuries occur from targets detonated at distances far shorter than these minimums, often with the target placed inside an object that significantly expands the debris field. Always follow the manufacturer's minimum distance guidelines — when in doubt, move further back. Never enclose Tannerite inside containers, vehicles, or any object that could become shrapnel. For the full safety breakdown, see our Tannerite safety guide.
Can Tannerite catch fire or explode without being shot?
No. Properly formulated binary targets including Tannerite brand products are specifically designed to be non-flammable and non-detonatable by any means other than high-velocity bullet impact. Dropping a mixed target, striking it with a hammer, exposing it to open flame, or running low-velocity rounds through it will not initiate detonation. The mixture requires the specific shock energy of a high-velocity bullet traveling above approximately 2,000 fps. This velocity threshold is a genuine safety design characteristic, not a marketing claim. Note that the explosion, once initiated, can ignite flammable materials in the immediate vicinity — do not use Tannerite in dry conditions near brush or vegetation.
Can I use Tannerite for a gender reveal?
Yes — Tannerite gender reveals are legal in most states and have become a popular format. Colored powder or chalk is mixed with the Tannerite components before use, producing a colored cloud on detonation. The same minimum safe distances and legal restrictions apply to gender reveal use as to any other Tannerite application. Never use Tannerite gender reveals in dry conditions near vegetation — the detonation can ignite surrounding materials. Always verify local laws and obtain landowner permission if not on your own property. See our dedicated gender reveal guides for more information.
