7.1 Explosives and Never-Fly Items

7.1 Explosives and Never-Fly Items

Quick answer: On TSA's live Flammables and item pages, bang snaps, blasting caps, dynamite, fireworks, firecrackers, sparklers, flares, flare guns, gun powder (including black powder and percussion caps), hand grenades, and realistic replicas of explosives or incendiaries are No carry-on / No checked. They are never-fly items: they do not travel in the cabin and they do not travel in the hold. TSA's Civil Enforcement page groups blasting caps, dynamite, gunpowder over 10 oz., hand grenades, plastic explosives, and other high explosives at $10,230–$17,062 plus criminal referral. Consumer fireworks, novelty fireworks, professional display fireworks, flares, and gunpowder of 10 oz. or less are $450–$2,570. The final decision rests with the TSA officer.

This section is public prohibited-item knowledge for the Transportation Security Officer (TSO) Assessment Battery (TAB) and for the job. It is not a construction lesson. Do not treat this chapter as instruction in improvised explosive devices, detonator wiring, firing trains, or unpublished component lists. TSA's Sensitive Security Information program protects information that, if publicly released, would be detrimental to transportation security, as defined by 49 C.F.R. Part 1520. Officers and other covered persons must not disclose SSI. What you study here is what TSA already publishes to the traveling public: named items, carry-on versus checked results, and civil-penalty categories.

Never-fly means both columns are No

Knives, bats, and unloaded firearms have a checked path. Explosives in the public What Can I Bring catalog generally do not. Bang snaps are No / No. Blasting caps are No / No. Dynamite is No / No, with TSA sending regulatory questions to the FAA PackSafe list. Fireworks and firecrackers are No / No. Sparklers are No / No. Flares and flare guns are No / No. Gun powder, including black powder and percussion caps, is No / No. Hand grenades are No / No.

A traveler who says "it is only a bang snap" or "it is only a sparkler for the holiday" is describing a never-fly item. There is no published cabin exception for a small quantity, a spent casing, or a souvenir that is still the listed item. If the object is the listed object, both columns are No. If the traveler has no other bag, the item still does not fly. Surrender, disposal under local procedure, or not traveling with it are the public outcomes — not a sterile-area exception.

Do not confuse gun powder with ammunition. Small-arms ammunition has a checked packing path (Chapter 5). Gun powder, including black powder and percussion caps, is a different listing: No / No. A flare gun is also No / No, unlike a conventional firearm that may travel unloaded in a locked hard-sided checked case after airline declaration. Learn the item page, not a family resemblance.

Realistic replicas of explosives are No / No. Realistic replicas of incendiaries are No / No. Civil enforcement treats realistic replicas of explosives, inert hand grenades, and intact vehicle air bags as $850–$4,250 plus criminal referral, including when they are found in checked baggage. A replica is not a loophole because it "cannot go off." The public listing is the same as a live never-fly item: it does not fly.

Never-fly versus checked-only

The table below is the public map for this chapter. Never-fly means No / No. Checked-only candidates (purged engines) belong to section 7.2. Generally permitted tobacco is listed so you do not treat cigarettes as explosives.

The final decision rests with the TSA officer on whether an item is allowed through the checkpoint. Even a generally permitted item may receive additional screening or be refused if it alarms, appears tampered with, or poses other security concerns.

TSA security rules and FAA PackSafe are both in force

TSA's Security Screening page states that most hazardous materials are forbidden in carry-on and checked baggage, with a few exceptions for some personal items such as toiletries, medicines, battery-powered electronics, and assistive devices. For transporting hazardous materials, TSA points travelers to the Federal Aviation Administration PackSafe list.

PackSafe is the dangerous-goods safety overlay. It states that some items packed in baggage may be hazardous material; most dangerous goods are forbidden in carry-on and checked baggage; and limited exceptions exist for some personal items such as toiletries, medicines, and assistive devices. PackSafe lists common dangerous-goods classes: explosives, gases, flammable liquids and solids, oxidizers, toxic and infectious materials, radioactive materials, corrosives, and other items that can endanger the traveling public when not handled correctly. Vibrations, static electricity, and temperature and pressure changes can cause items to leak, generate toxic fumes, start a fire, or explode. PackSafe also states that TSA security rules on prohibited items are separate from FAA dangerous-goods safety rules, even when the lists overlap, and that dangerous goods that are improperly packaged, not permitted, leaking, or hidden / artfully concealed are subject to civil and criminal penalties.

A TSO candidate should hold both maps: What Can I Bring is the checkpoint security listing; PackSafe is the hazmat safety listing. Neither map lets dynamite, blasting caps, fireworks, or gun powder onto the aircraft.

Civil enforcement categories, not a DIY recipe

TSA may impose civil penalties of up to $17,062 per violation per person. Repeat violations draw higher penalties. Proposed amounts are generally set at the low end of a category; aggravating facts can raise them. Learn the buckets, not a promised dollar amount.

At the checkpoint, sterile area, or onboard, and in checked baggage:

• Blasting caps; dynamite; gunpowder (more than 10 oz.); hand grenades; plastic explosives; all other high explosives — $10,230–$17,062 + criminal referral
• Consumer fireworks, novelty fireworks, professional display fireworks; flares; gunpowder (10 oz. or less) — $450–$2,570
• Realistic replicas of explosives; inert hand grenades; intact vehicle air bags — $850–$4,250 + criminal referral

The 10 oz. gunpowder figure is a penalty-band split, not a packing allowance. Gun powder remains No / No whether the quantity is a pinch or a can. Fireworks remain No / No whether they are labeled consumer, novelty, or professional display.

A Notice of Violation is a civil matter. Criminal referral is separate. Local or state charges are separate from TSA's civil process. Officers at the lane cannot promise a traveler that no civil penalty will issue; screening personnel forward the incident, and the regulatory process decides later.

Artful concealment of a prohibited item is its own published concern. TSA's other-violations table includes tampering with, interfering with, compromising, modifying, or attempting to circumvent a security system, measure, or procedure, including the artful concealment of prohibited items. The sanction amount is based on the underlying security requirement. This section does not teach how to hide a threat. It teaches that concealment does not create a packing exception.

Image aptitude without unpublished components

The TAB evaluates x-ray / image-interpretation aptitude. TSA does not publish a dual-energy color SOP on TSA.gov. Some commercial object-recognition training decks describe an organic mass with wires as a general public threat-awareness cue. Treat that phrase as general public threat-awareness, not as SSI, not as an official component list, and not as a wiring diagram. Do not memorize unpublished initiator, switch, or power-source inventories.

What is public: if the object matches a listed never-fly item — dynamite, a blasting cap, fireworks, a grenade shape, a flare — it does not fly. If the image is a realistic replica, it still does not fly. If the image is unclear because of overlap or clutter, section 7.3 covers the public duty to resolve the image, not to guess it is "probably a souvenir."

Realistic scenario

A traveler puts a handful of bang snaps and a sparkler pack in a toiletry bag "because they are novelty items" and a replica grenade keychain in the same pouch "because it is inert." Bang snaps are No / No. Sparklers are No / No. Realistic replicas of explosives are No / No. None of those items has a checked path on the live listings. The officer does not split the difference for a holiday, a campsite, or a "it's fake" story. High explosives and live blasting caps, if present, sit in the highest civil-penalty band plus criminal referral. Fireworks and flares sit in a lower published band, still prohibited. The replica grenade is still never-fly and still a published civil-penalty item. The final decision rests with the TSA officer.
