ATF evaluates air guns on a case-by-case basis. A pre-charged pneumatic rifle with a bore exceeding 0.50 caliber and capable of expelling a projectile with significant force may be classified as a destructive device under the National Firearms Act, triggering registration and transfer requirements. Importers of large-caliber PCP rifles should seek an ATF classification ruling before importation.

Yes. The CPSC, in coordination with the industry standard ASTM F589, requires that non-powder guns sold in the US carry specific safety warnings on the product and packaging. Importers are responsible for ensuring that labeling meets these requirements before the goods enter retail channels, and non-compliant products may be subject to recall or civil penalties.
