Collectors
Firearms and Ammunition Technology Division (FATD) classifications determine whether or not a firearm is regulated under the Gun Control Act or National Firearms Act (NFA). FATD also evaluates firearms (and other defense articles) for suitability to be imported and conducts examinations of ammunition.
Please be aware that FATD does not make determinations based on drawings, photographs, written descriptions, or diagrams. In order to render an appropriate classification, please ship the physical item and any supporting information to the following address:
Bureau of Alcohol, Tobacco, Firearms, and Explosives
Firearms & Ammunition Technology Division
244 Needy Road
Martinsburg, WV 25405
Please ship your item to FATD with a prepaid return shipping label with tracking for the return of your item. Providing a shipping account number instead of a trackable prepaid shipping label will not be accepted.
The U.S. Postal Service recommends that long guns be sent by registered mail and that no marking of any kind which would indicate the nature of the contents be placed on the outside of any parcel containing firearms.
You cannot ship a handgun or ammunition through the U.S. Postal Service. A commercial carrier must be used to ship a handgun. Please check with the specific carrier before shipping to ensure your package meets all of legal requirements.
Do not use packing peanuts or similar types of packing material that may become lodged into moving parts of the item or device and cause safety issues. Small parts and pieces must be placed into a sealed zip-lock type clear plastic bag to prevent loss.
FATD may be unable to return the sample if the item is classified as an unregistered NFA weapon (machinegun, silencer, short barreled rifle, short barreled shotgun, etc.), or any other legally prohibited item.

All firearms other than shotguns and rifles, and all ammunition other than ammunition for shotguns or rifles may be sold only to individuals 21 years of age or older. Licensees are bound by the minimum age requirements established by the GCA regardless of state or local law. However, if state law or local ordinances establish a higher minimum age for the purchase or disposition of firearms, the licensee must observe the higher age requirement.

Also, the parent or guardian giving the written consent may not be prohibited by law from possessing a firearm. Moreover, state law must not prohibit a person less than 18 years of age from possessing the handguns or ammunition.
[18 U.S.C. 922(x)]
Yes, provided the buyer is 18 years of age or older, and the licensee is satisfied that the ammunition is for use in a rifle. If the ammunition is intended for use in a handgun, the buyer must be at least 21 years of age.

Yes. A license is required to import or manufacture ammunition. However, a license is not required to deal only in ammunition. Ammunition includes cartridge cases, primers, bullets or propellant powder designed for use in any firearm other than an antique firearm.

A person who is prohibited from possessing, shipping, transporting, or receiving firearms or ammunition may make application to the Attorney General for relief from the firearms disability. The Attorney General may grant such relief if it is established to the Attorney General’s satisfaction that the circumstances regarding the disability, and the applicant’s record and reputation, are such that the applicant will not be likely to act in a manner dangerous to public safety and that the granting of relief would not be contrary to the public interest. See 18 U.S.C. § 925(c).
On March 20, 2025, the Department of Justice issued an interim final rule. As a result, ATF no longer has authority to process applications for relief from firearms disabilities. See https://www.federalregister.gov/documents/2025/03/20/2025-04872/withdrawing-the-attorney-generals-delegation-of-authority. For those interested in pursuing relief under Section 925(c), please note the Interim Final Rule’s statement that “the Department anticipates future actions, including rulemaking consistent with applicable law, to give full effect to 18 U.S.C. 925(c) while simultaneously ensuring that violent or dangerous individuals remain disabled from lawfully acquiring firearms.” 90 Fed. Reg. at 13,083.
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.
