Where required by law, sellers must also hold the appropriate Special Occupational Tax (SOT) designation:

- Class 3 SOT – Dealers
Sellers who do not possess the required licenses and tax status may not list NFA items.
2. Category Selection

NFA transfer approval times may vary and can take several months.

- Correct any deficiencies and relist the item, if permitted.
- Contact GunBroker Support if you believe the removal occurred in error.
State and Local Restrictions
