Last updated: August 2026 dataMilitary weapon components — covering parts for artillery, military rifles, shotguns, and suppressors under heading 9301 — are among the most tightly controlled imports in the US tariff schedule, governed by both ATF and the State Department's Directorate of Defense Trade Controls (DDTC) under the International Traffic in Arms Regulations (ITAR). The United Kingdom and Germany are the leading suppliers, consistent with NATO allied-nation defense procurement channels. The six 10-digit lines distinguish between artillery parts (9305913010), military suppressors (9305913020), and parts for military rifles (9305911000) and shotguns (9305912000), each potentially subject to different ITAR licensing requirements. Importers must determine whether a specific component appears on the US Munitions List before attempting entry.

In most cases, yes. Components for military weapons that appear on the US Munitions List (USML) require a DDTC import license under ITAR, separate from any ATF Form 6 permit. The two regulatory regimes operate in parallel: ATF controls the import as a firearm or firearm part, while DDTC controls the transfer as a defense article. Importers should conduct a USML review and consult with an ITAR-registered broker before shipment.
Military suppressors classified under 9305913020 as parts of heading 9301 weapons are subject to both NFA registration requirements and ITAR controls, making their import pathway more restrictive than commercial suppressors under heading 9305. Only entities with appropriate ATF SOT/Class III licensing and active DDTC registration may import them, and end-use certificates are typically required to satisfy both agencies.
