Quoted: My understanding is that if your trust or company is registered in your state, you have to notify and get permission to transport Class III weapons out of that state, but if you have an overseas trust or company, this provision does not apply.

Before BATF approves a transfer to a new owner, it must verify that the NFA item is legal in the applicant's state. If the applicant does not have a state of residence or registration, the transfer cannot be approved.

An offshore or overseas corporation with no U.S. registration may contact a U.S.-based dealer or manufacturer and arrange for an export to their home country via submission of an End User Certificate, a DSP-5 from the U.S. State Department, and BATF approval of a Form 9. However, before bringing the item back into the U.S., BATF must approve an import Form 6 and the item must first be transferred to the U.S. importer.

All NFA-Registered items must be kept in the state listed on the Form 1 of Form 4; transportation outside that state is a felony, unless the item is C&R-listed and the registrant also holds a valid C&R license.
