This bill proposes to extend the authority of the United States Postal Service (USPS) to issue a special postage stamp designed to raise funds for breast cancer research. Known as a semipostal stamp , a portion of its sales price above the regular postage rate is dedicated to a specific cause. The legislation specifically amends section 414(h) of title 39, United States Code, to change the expiration date of this authority. The current authorization, which is set to expire in 2027, would be extended by an additional decade, moving the new expiration to 2037 . This reauthorization ensures the continued operation of the program, providing a dedicated funding stream for vital breast cancer research initiatives for another ten years.
