Fineness Requirements
Under IRS Publication 590-A, precious metals in an IRA must meet minimum purity standards: gold must be 99.5% pure (0.995 fine), silver must be 99.9% pure (0.999 fine), platinum must be 99.95% pure, and palladium must be 99.95% pure. The sole exception is the American Gold Eagle, which is specifically permitted at 91.67% purity (22 karat) despite falling below the general 99.5% threshold.
Approved Products
Eligible products must be produced by a national government mint or by a refiner/assayer/manufacturer accredited by NYMEX, COMEX, or an equivalent international authority. Bars must meet minimum weight and fineness standards. Coins must be non-collectible bullion coins — proof coins may qualify if in original mint packaging with certificate of authenticity.
Storage Requirements
IRA-held precious metals must be stored at an IRS-approved third-party depository. Home storage is not permitted and constitutes a taxable distribution. SD Bullion ships directly to approved depositories including Delaware Depository (Wilmington, DE) and Brink's Global Services. Segregated storage (your metals stored separately from others) is available at a modest additional fee.
