Expands and strengthens federal buying of biobased products by adding new procurement rules, reporting, training, and verification requirements for agencies and suppliers. It requires annual procurement updates, a domestic preference statement, updates to product catalogs, new reporting items, mandatory training for procurement staff, verification duties for sellers or agencies, and directs a two-year Government Accountability Office review of implementation.

These changes increase compliance and documentation duties for federal agencies and government contractors, aim to boost purchase of domestic biobased goods, and create a near-term audit of how well the changes are being carried out.
