The Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) published a series of firearms, ammunition, explosives and defense article regulatory updates on May 6, 2026. While some are final rules now in effect or taking effect soon, others are proposed rules with open comment periods.
For importers, manufacturers, federal firearms licensees and companies handling regulated defense articles, these notices are important because they may affect import permit review, product classification, marking requirements, recordkeeping obligations and country-of-origin restrictions.
Key Updates
Plastic explosives import filings: ATF issued a final rule removing the requirement that importers submit the required written attestation in triplicate when importing plastic explosives. The written statement is still required, but the three-copy filing requirement is being removed as an administrative burden. The rule is effective June 5, 2026.
Machine gun definition: ATF issued a final rule revising the regulatory definition of “machine gun” following the Supreme Court’s decision in Garland v. Cargill. The rule removes language that had incorporated bump-stock-type devices into the regulatory definition. The rule became effective May 6, 2026.
AECA component definitions: ATF proposed adding definitions for “component,” “accessories and attachments,” and “part” under regulations implementing the Arms Export Control Act for permanent imports. Comments are due July 6, 2026.
NFA firearm markings: ATF proposed allowing makers of National Firearms Act firearms to adopt certain existing markings already placed on the firearm to satisfy NFA marking requirements. Comments are due July 6, 2026.
Firearm records retention: ATF proposed replacing indefinite retention requirements for certain federal firearms licensee acquisition and disposition records with a specific retention period, and is considering either 20 or 30 years. Comments are due August 4, 2026.
Training rounds: ATF proposed clarifying that certain training rounds do not meet the Gun Control Act definition of “ammunition” and are not regulated under the Arms Export Control Act. ATF also noted that less-than-lethal ammunition remains distinct and generally continues to be treated as ammunition. Comments are due August 4, 2026.
Proscribed countries: ATF proposed updating its import restriction rules by removing an outdated list of proscribed countries and instead referencing the Department of State’s list. The proposal would also remove the list of former Soviet countries currently restricted for most firearms and ammunition imports, leaving only the Russian Federation as the proscribed country of origin for those imports. Comments are due July 6, 2026.
What Importers Should Watch
These updates signal a broader effort by ATF to modernize, clarify and streamline firearms-related regulations. Importers should review whether any pending or future transactions involve regulated firearms, ammunition, defense articles, explosives, components, training rounds or products from restricted countries.
Companies should also confirm that product descriptions, country-of-origin documentation, ATF Form 6 submissions, recordkeeping practices and internal compliance reviews align with the applicable rule status. Proposed rules are not yet final, but affected businesses may want to evaluate operational impacts and consider submitting comments before the applicable deadlines.
