ATF Form 6A, Release and Receipt of Imported Firearms, Ammunition and Defense Articles - also known as the ATF Form 5330.3C or the ATF E-Form 6A - is a form you are required to fill out for most importations of firearms, defense articles, and ammunition. The form is distributed by the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) and was last updated in January 2018. The ATF Form 6A fillable version is available for download below.
Fill out this form when you import firearms, ammunition, or defense articles authorized for importation on ATF Form 6 Part I and ATF Form 6 Part II. You will receive a blank form with your approved import permit. For your items to be released from the custody of the Customs and Border Protection (CBP), you are required to present the completed ATF Form 6A and your import permit to the CBP.
The main purpose of the form is to determine that the importation has taken place, verify that the items were released and received by the importer or designated agent, and confirm that the released items were the items described in the application for importation.
