Questions and Answers

Applying for a Federal Explosives License

The Safe Explosives Act (SEA) requires ATF to act on a properly completed application within 90 days. ATF usually considers an application to have been properly completed when all required information has been provided to ATF in writing. This includes submission of the correct number of legible fingerprint cards, the correct fee, etc.

If material changes have to be made to an application (e.g., a change from one license type to another or the addition of or changes to the responsible persons, different business name, premises address, hours of operation, EIN, etc.) after its initial receipt by the Federal Explosives Licensing Center (FELC), then the 90-day processing period may re-start.

The FELC generates licenses and permits every day based on the receipt of field recommendations. Licenses and permits are sent first class mail to an applicant’s mailing address of record from the FELC in Martinsburg, West Virginia.

ATF Form 4473

No. ATF Form 4473 is required only for transfers by a licensee.   [27 CFR 478.124]

No. The ATF Form 4473 is required only for sales or dispositions by a licensed manufacturer, importer, or dealer.

[18 U.S.C. 923(g); 27 CFR 478.124]

If the buyer or transferee is unable to read and/or write, the answers (other than the signature) may be written on the form by another person, excluding the seller. Two persons not directly involved in the firearms transaction (excluding, for example, the licensee and employees of the licensee) must sign as witnesses to the buyer’s answers and signature.

[27 CFR 478.21]

Auctioneers

Generally no, because most auctions do not qualify as a gun show or qualifying event and therefore a licensee would not be permitted to conduct business away from the licensed premises.

[18 U.S.C. 923(j); 27 CFR 478.100]

In a consignment auction, firearms may be displayed at an auction site away from the auctioneer’s licensed premises and sales of the firearms can be agreed upon at that location, but the firearms must be returned to the auctioneer’s licensed premises prior to transfer. The simultaneous sale and delivery of the auctioned firearms away from the licensed premises would violate the law, for example, engaging in business at an unlicensed location.

However, if the auctioneer is assisting an estate in disposing of firearms, the estate is the seller of the firearms and the estate is in control and possession of the firearms. In this situation, the firearms may be sold by the estate at the auction site.

[18 U.S.C. 923(a); 27 CFR 478.50]

Collectors

Licensed collectors are required to comply with written notification to unlicensed individuals upon delivery of a handgun. However, the sign posting requirement does not apply to licensed collectors.

[27 CFR 478.103]

Conduct of Business

A licensee may not allow an individual who is a prohibited person to receive or possess firearms or ammunition, including persons employed by the licensee.

[18 U.S.C. 922(g) or (n), and 2]

No. A frame or receiver is a type of firearm “other than a shotgun or rifle” and the transfer by a licensee to an individual less than 21 years of age would be prohibited.

[18 U.S.C. 921(a)(5) and (7) and 922(b)(1); 27 CFR 478.11 and 478.99(b)]

No.

[18 U.S.C. 922(b)(3); 27 CFR 478.99(a)]

The following steps must be followed prior to transferring a firearm:

1. The licensee must have the transferee complete and sign ATF Form 4473, Firearms Transaction Record.

2. The licensee must verify the identity of the transferee through a government–issued photo identification.

3. Unless an exception applies, the licensee must contact NICS through either the FBI or a State point of contact (POC). A licensee may not transfer a firearm unless the licensee receives a “proceed” response, or three business days have elapsed since the licensee contacted National Instant Criminal Background Check System (NICS), and the system has not notified the licensee that the receipt of a firearm by such other person would violate the law. Licensees contacting the FBI directly and receiving a “delayed” response will receive information from the FBI indicating when the 3 business day time period elapses. A licensee may not transfer a firearm where a “denied” response is issued by NICS.

Final Rule - 2021R-05F

The final rule clarifies that the definition of “firearm” includes a weapon parts kit that is designed to or may readily be completed, assembled, restored, or otherwise converted to expel a projectile by the action of an explosive. It also clarifies that the term “firearm” does not include a weapon, including a weapon parts kit, in which the frame or receiver of such weapon is “destroyed” as described in the definition “frame or receiver.” The final rule also explains that persons engaged in the business of selling or distributing weapon parts kits cannot avoid licensing, marking, recordkeeping, or other requirements to which federal firearms licensees (FFLs) are subject ‘‘by selling or shipping the parts in more than one box or shipment to the same person, or by conspiring with another person to do so.’’

Licensees who require a determination whether a weapon parts kit is a regulated firearm may contact ATF’s Firearms and Ammunition Technology Division (FATD) for a determination.

No. In cases where the acquiring FFL is contracting out marking services of PMFs to a licensed gunsmith (or unlicensed engraver), the gunsmith or engraver may only perform such engraving services on the spot under the direct supervision of the requesting FFL. The marking FFL need not record the PMF in his/her A&D records.

Fireworks

Any fireworks defined as "display fireworks" in 27 CFR 555.11 may be lawfully received or transported only by persons who hold a valid license or permit. No ATF license or permit is required to receive or transport "consumer fireworks" or "articles pyrotechnic".

[18 U.S.C. 842(a)(3); 27 CFR 555.26, 555.141(a)(7)]

Yes. Display fireworks include, but are not limited to, salutes containing more than 2 grains (130 mg) of flash powder, aerial shells containing more than 40 grams of pyrotechnic compositions (excluding the lift charge), and other display pieces which exceed the limits of explosive materials for classification as "consumer fireworks". These fireworks are classified as fireworks UN0333, UN0334, or UN0335 by regulations of the U.S. Department of Transportation at 49 CFR 172.101. Display fireworks also include fused set pieces containing components which together exceed 50 mg of salute powder. Any fireworks defined as “display fireworks” in 27 CFR 555.11 may be lawfully received or transported only by persons who hold a valid license or permit. No ATF license or permit is required to receive or transport “consumer fireworks” or “articles pyrotechnic”.

[18 U.S.C. 842(a)(3); 27 CFR 555.26, 555.141(a)(7); 27 CFR 555.11: definition of "display fireworks"]

General

Yes, a person who —

(1) Has been convicted in any court of a crime punishable by imprisonment for a term exceeding 1 year;

(2) Is a fugitive from justice;

(3) Is an unlawful user of or addicted to any controlled substance;

(4) Has been adjudicated as a mental defective or has been committed to a mental institution;

(5) Is an alien illegally or unlawfully in the United States or an alien admitted to the United States under a nonimmigrant visa;

(6) Has been discharged from the Armed Forces under dishonorable conditions;

(7) Having been a citizen of the United States, has renounced his or her citizenship;

(8) Is subject to a court order that restrains the person from harassing, stalking, or threatening an intimate partner or child of such intimate partner issued after a hearing

at which notice was given to the person and at which the person had an opportunity to participate, and includes a finding that the person subject to the order represents a credible threat to the intimate partner or child or the intimate partner OR explicitly prohibits the use, attempted use, or threatened use of force against the partner; or

(9) Has been convicted of a misdemeanor crime of domestic violence cannot lawfully receive, possess, ship, or transport a firearm or ammunition,is prohibited from shipping, transporting, possessing, or receiving firearms and ammunition.

A person who is under indictment or information for a crime punishable by imprisonment for a term exceeding 1 year cannot lawfully ship, transport, or receive a firearm or ammunition. Such persons may continue to lawfully possess firearms and ammunition obtained prior to the indictment or information, but cannot do so once the conviction becomes final.

[18 U.S.C. 922(g) and (n); 27 CFR 478.32]

Persons convicted of a disabling offense may seek to have their firearms rights restored by means other than a federal relief from firearms disabilities pursuant to 18 U.S.C. § 925(c). Other means of restoring firearms rights include:

A person convicted of a federal offense may apply for a presidential pardon. 28 CFR Part I specifies the rules governing petitions for obtaining presidential pardons. You may contact the Pardon Attorney’s Office at the U.S. Department of Justice to inquire about the procedures for obtaining a presidential pardon.

A person convicted of a state offense may contact the State Attorney General’s Office in the state of their conviction for information concerning the availability of expungements, set asides, pardons and civil rights restoration.

Any pardon, expungement, set aside, or restoration of civil rights must completely remove the effects of a prior conviction, including any restrictions on the shipment, transportation, receipt, and possession of firearms, for firearms rights under federal law to be restored.

Because black powder firearms are considered antique firearms, the possession of a black powder firearm by a person subject to federal firearms disabilities is not prohibited by the GCA. However, a person subject to federal firearms disabilities may not receive and/or possess black powder firearms that can be readily converted to fire fixed ammunition by replacing the barrel, bolt, breechblock, or any combination thereof which are classified as "firearms." Additionally, state law may prohibit the possession of a black powder firearm by persons who are not federally prohibited from possessing them. Please contact your state's Attorney General’s Office for information regarding black powder firearms.

[18 U.S.C. 921(a)(3) and (16); 27 CFR 478.11 and 478.141(d)]

General Questions - Explosives

Yes. No person shall knowingly distribute explosive materials to any individual listed in 27 CFR 555.26, or to an individual who is under 21 years of age.

[18 U.S.C. 842(d); 27 CFR 555.26(d)]

Yes. The law prohibits the receipt or possession of explosive materials by any person listed in 27 CFR 555.26.

[18 U.S.C. 842(i); 27 CFR 555.26, 555.49(b)]

No. Every person who receives explosive materials must first obtain a federal explosives license or permit. Distribution of explosive materials to persons who do not hold a license or permit is unlawful. Also, see 18 U.S.C. 845 and 27 CFR 555.141 for exemptions.

[18 U.S.C. 842(a), 842(b); 27 CFR 555.26(a), 555.106]

Generally, any person who has knowledge of the theft or loss of any explosive materials from his/her stock must report such theft or loss within 24 hours of discovery to ATF and to appropriate local authorities.

This theft/loss reporting requirement in the federal explosives laws at 18 U.S.C. § 844(p) and 27 CFR 555.30 refers to explosive materials when the owner, authorized possessor or operator has unintentionally lost possession, care, or control of the explosives materials and cannot account for their absence, even if there is reason to believe that the theft or loss occurred prior to receipt of an explosive materials shipment (e.g., during transportation or packing at the manufacturer’s premises).

Any licensee or permittee who has knowledge of the theft or loss of any explosive materials from his or her stock shall, within 24 hours of discovery, report the theft or loss by telephoning our toll-free number 800-461-8841 during business hours (Monday-Friday, 8 a.m.-5 p.m. Eastern Time) or our nationwide toll-free hotline 888-283-2662 (after hours and weekends) and then submitting ATF Form 5400.5, "Report of Theft or Loss—Explosive Materials", in accordance with the instructions on the form. The theft or loss shall also be reported to appropriate local authorities.

The same requirements are imposed upon persons other than licensees and permittees, except that non-licensees and non-permittees, other than carriers, need not report a theft or loss on Form 5400.5, but must report the theft or loss by telephone, using the same numbers listed above, and in writing to the nearest ATF office. The theft or loss shall also be reported to appropriate local authorities.

Carriers of explosive materials who have knowledge of the theft or loss of any explosive materials must report such theft or loss within 24 hours of discovery to ATF and to appropriate local authorities. Carriers need not make the report on the ATF form or in writing.

See 27 CFR 555.30 for the specific information required to be reported in connection with a theft or loss.

[18 U.S.C. 842(k), 18 U.S.C. 844(p); 27 CFR 555.30]

Black powder is an explosive material for purposes of federal explosives laws and regulations.

However, the law exempts from regulation commercially manufactured black powder in quantities not exceeding 50 pounds (as well as percussion caps, safety and pyrotechnic fuses, quills, quick and slow matches, and friction primers) intended to be used solely for sporting, recreational, or cultural purposes in antique firearms as defined in 18 U.S.C. 921(a)(16) or in antique devices exempted from the term "destructive device" in 18 U.S.C. 921(a)(4).

Regardless, persons engaged in the business of importing, manufacturing, or dealing in black powder in any quantity must have a federal explosives license, and comply with recordkeeping, storage and conduct of business requirements.

[18 U.S.C. 841(c), 841(d), 845(a)(5); 27 CFR 555.11: definitions of "explosives" and "explosive materials", 555.141(b)]

Yes. Federal explosives law prohibits any person from distributing explosive materials to persons under 21 years of age. However, it does not prohibit the delivery to or possession of explosive materials by persons under the age of 21 who are receiving or using the materials on behalf of their employers to whom the materials were lawfully sold.

[18 U.S.C. 842(d), (i); 27 CFR 555.11 (definition of "distribute"), 555.26, 555.106(b)(1)]

Yes. A license or permit will not be issued to any person who:

(a) Is under indictment for, or who has been convicted in any court, of a crime punishable by imprisonment for a term exceeding one year;

(b) Is a fugitive from justice;

(c) Is an unlawful user of or addicted to any controlled substance (as defined in section 102 of the Controlled Substances Act, 21 U.S.C. § 802);

(d) Has been adjudicated a mental defective or who has been committed to a mental institution;

(e) Is an alien (with certain exceptions);

(f) Has been discharged from the armed forces under dishonorable conditions; or,

(g) Having been a citizen of the United States, has renounced his citizenship.
