ATF Form 6 is the official application and permit required by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) for importing firearms, ammunition, tobacco, explosives, or certain defense articles into the United States. ATF Form 6 must be filed and approved before importing regulated firearms, ammunition, or defense articles into the United States when a permit is required. Form 6 is the approved ATF form that captures all details needed to evaluate and authorize an import shipment.
Required information includes:
- Importer name, address, and federal firearms license number
- Foreign shipper name and country of origin
- Item description including type, model, caliber or gauge, and quantity
- Serial number for each firearm where applicable
- Intended use of the imported items such as commercial sale, demonstration, or competition
A Form 6 import permit application is required in the following scenarios:
- Commercial importation of firearms, ammunition, or defense articles by a licensed FFL importer
- Sample imports of federal firearms for demonstration or evaluation
- Return of goods originally exported under armed forces or government authority
- Temporary imports for competitions, trade shows, or short-term use
- Any import of a destructive device or item requiring additional review under federal law
Understanding the difference between ATF Form 6 and Form 6A
Form 6 and Form 6A serve distinct but complementary roles in the firearms import process. Form 6 authorizes the import before a shipment departs. Form 6A documents what was actually received once the shipment clears Customs. Together, they create a closed-loop compliance record governed by 27 CFR Part 478 Subpart G.
Form 6 | Form 6A | |
Purpose | Authorizes and permits the import | Documents release and receipt from Customs |
Timing | Filed before shipment departs | Form 6A is partially completed at the time of Customs release (Section I), and must be finalized by completing Section III and submitting it to ATF within 15 days after release. |
Content | Intended import details | Actual shipment details matching what was released |
Submitted to | ATF for approval | Customs officer (original); copy retained by FFL |
Form 6A must capture exact item data including manufacturer, country of origin, type, model, caliber, serial number, and quantity that precisely matches what is released from Customs custody. Once the Customs officer accepts the original Form 6A, they forward the certified copy to the ATF as required by law.
How to import firearms and ammunition using ATF Form 6
The overall import process for FFLs and authorized importers flows through five key stages covering the application, approval process, Customs release, marking, and final recordkeeping.
- Application: Complete and submit Form 6 via ATF eForms before the shipment departs the country of origin.
- Approval: Based on current ATF processing data, Form 6 applications average approximately 3 days via eForms and 11 days via paper submission. However, ATF still recommends submitting applications up to 60 days in advance, as complex or incomplete applications can take significantly longer.
- Customs release: Present the approved Form 6 to U.S. Customs and Border Protection along with Form 6A (Section I completed). At the time of importation, the importer must also provide either a copy of the export license from the country of exportation authorizing the shipment or a certification under penalty of perjury that no export license is required. CBP will release the shipment once satisfied it was authorized by ATF.
- Marking: The importer must mark each firearm within 15 days of release from Customs custody with required identifying information, including the serial number, model, caliber or gauge, manufacturer, country of origin, and the importer’s name, city, and state, in accordance with 27 CFR 478.112 and 478.92. This requirement applies unless the firearm already bears compliant markings.
- Recordkeeping: Retain all import documentation in your official FFL records, including the approved Form 6 and completed Form 6A.
Temporary vs. Permanent Imports
- Temporary import. For short-term use, competitions, or demonstration only. No permanent transfer of ownership occurs, and items must be re-exported after the approved period.
- Permanent import. Results in transfer of ownership and requires stricter scrutiny, full marking compliance, and complete acquisition and disposition recordkeeping.
Preparing and Submitting Form 6
Accuracy at submission is the single biggest factor in a smooth approval process. ATF recommends electronic submission through the eForms system because electronic submission reduces errors, enables application status tracking, and generally speeds up review.
Required information for a complete Form 6 submission includes importer and foreign vendor details, item descriptions, country of origin, model, caliber or gauge, and serial numbers where applicable. Clear firearm photos matching how items are physically marked should also be attached to reduce ATF questions and delays.
Incomplete or illegible submissions are the most common cause of rejection. Missing signatures, unclear item descriptions, and absent photos will delay or deny your application.
Step-by-Step Submission Workflow:
- Gather all required documents: importer and foreign vendor details, item descriptions, serial numbers, country of origin, and photos of item markings.
- Log in to the ATF eForms portal and select Form 6.
- Complete all fields including importer, foreign shipper, item descriptions, and intended use. Match descriptions exactly to the physical markings on each item.
- Attach clear photos and labels that correspond to how each item is marked, to minimize additional information requests from ATF.
- Review every field, signature, and attachment for accuracy before submitting. Incomplete forms are a leading cause of delays in the approval process.

Receiving Approval and Handling Form 6A
Once ATF issues the approved form and permit, it is valid for the specific shipment described in the application. When that shipment arrives at the U.S. border:
- Present the ATF-approved Form 6 to the Customs officer. Border protection officers will not release the goods without a valid import permit on file.
- Complete Form 6A in duplicate at the time of Customs release, not after.
- Provide the original Form 6A to the Customs officer and retain your copy for FFL records.
- Ensure Form 6A lists every imported item with manufacturer, country, type, model, caliber or gauge, serial number, and quantity exactly as released from Customs custody.
- The Customs officer will forward the certified original Form 6A to the ATF as required by law.
Filing and Recordkeeping Requirements For Imported Items
FFLs and authorized importers must retain all import documentation in their official records. U.S. marking rules under 27 CFR 478.92 require the importer to properly mark all firearms within 15 days of release from Customs custody, unless the foreign manufacturer already applied compliant markings.
Recordkeeping checklist for every import:
- Approved ATF Form 6 import permit
- Completed and certified Form 6A
- Acquisition and disposition records (bound book)
- Photos and item manifests submitted with the Form 6 application
- Firearm markings documented within 15 days of Customs release
- Organized file storage covering all approvals, shipment docs, and supporting images

Legal Requirements and Compliance for Importers
Only compliant FFL importers operating under 27 CFR Part 478 Subpart G may initiate the import process. The relevant legal authority covers all aspects of the importation of firearms, ammunition, and implements of war into the United States. Core compliance obligations include:
- Submit complete and accurate forms with no missing fields, signatures, or attachments
- Ensure timely firearm marking within 15 days of Customs release
- Maintain all required records and avoid unauthorized changes to any approved ATF form or application
- Address any Special Occupational Tax (SOT) obligations for NFA items where applicable. See the ATF Ruling 2016-1 compliance checklist and ATF Ruling 2021R-05F checklist for related guidance.
- Cooperate promptly with any background checks or additional information requests from ATF or Customs
Failure to comply, including late filing, inaccurate records, or improper marking, can result in shipment seizure, fines, or license revocation.
Common Pitfalls and How to Avoid Delays at Customs
The most common reasons ATF imports are delayed or rejected come down to incomplete paperwork, mismatched item data, and late submission of Form 6A. Addressing these proactively keeps shipments moving and prevents non-restricted firearms from being held unnecessarily in Customs custody.
Issue | Fix |
Incomplete Form 6 | Check every required field, signature, and attachment before submission |
Serial number, model, or caliber mismatch | Validate all markings against shipping manifests before filing |
Missing sporting status or lawful sporting purposes documentation | Include sporting configuration evidence for all applicable firearms |
Missing photos or item labels | Attach clear photos matching physical markings on each item |
Late or absent Form 6A | Complete Form 6A in duplicate at the moment of Customs release, not after |
Unauthorized changes after approval | Submit a new Form 6 for any changes to the approved shipment details |
If Customs or ATF issues a request for additional information, respond immediately. Documentation commonly reviewed includes sporting configuration details, markings photos, and your acquisition and disposition bound book. Importers handling non-immigrant alien clients or customers should also be prepared to provide relevant background checks documentation as part of the review.
