432.24 Certificate of Manufacturers, Dealers, and Importers
A federal firearms licensee manufacturer, dealer, or importer need not file the affidavit under 432.22, but must file with the Postmaster a statement on PS Form 1508, Statement by Shipper of Firearms, signed by the mailer that he or she is a licensed manufacturer, dealer, or importer of firearms. The mailer must also state that the parcels containing handguns, or parts and components of handguns under 432.2d, are being mailed in customary trade shipments or contain such articles for repairing or replacing parts, and that to the best of their knowledge the addressees are licensed manufacturers, dealers, or importers of firearms. Registered Mail service is recommended.
Postmasters may forward an unsatisfactory mailer statement to the PCSC for a ruling.
