Unfortunately it's not that simple. While FDA does allow such blood to be donated, donors must pass the standard screening criteria and not all donors will qualify. Donors with hemochromatosis often must be screened by a physician at time of donation. There are additional labeling requirements for blood donated from hemochromatosis patients which add increased costs and extra steps to the manufacturing process. These additional requirements and costs make the provision of hemochromatosis donor blood too expensive for many facilities. Blood Bank of AK is not alone in this, the Red Cross is one of the highest volume suppliers in the US and doesn't accept donations from hemochromatosis patients.
From FDA: "the blood establishment must either 1) label the collected blood with the donor's disorder and have a physician examine the donor on the day of donation if less than eight weeks has passed since the previous donation, or 2) apply for the variances."
