The Back-to-School Supplies Affordability Act would prevent the federal government from imposing tariffs on school supplies and educational materials that exceed the tariff rates that were in effect on January 19, 2025. The bill specifically protects items like notebooks, backpacks, pens, pencils, crayons, keyboards, and other classroom supplies from tariff increases, as well as any items the Secretary of Commerce designates as school supplies used in elementary or secondary classrooms. Congress could block specific items from this protection by passing a joint resolution of disapproval. The legislation affects students, families, teachers, schools, and local governments by keeping the costs of educational materials affordable. The Secretary of Commerce must report to Congress every 180 days on which items are exempt from increased tariffs under this act.
