US SB89

Amends 18 U.S.C. § 925(d) to expand the definition of firearms and ammunition eligible for importation under "sporting purposes" to explicitly include those designed for hunting, recreational target shooting, organized competitions, and civilian rifle match competitions

Requires the Attorney General to make importation determinations within 90 days of request; if no determination is made by the deadline, importation is automatically deemed allowed

Prohibits the Attorney General from denying importation of firearms or ammunition that are "substantially similar" to those already in circulation in the United States

Mandates written denial explanations be provided to applicants and posted on the ATF website, with applicants entitled to a hearing at a convenient location and subsequent de novo judicial review in federal district court

Places the burden of proof on the Attorney General in judicial review proceedings and requires award of reasonable attorney fees if the court rules against the denial
