Securing American Agriculture Act This bill directs the Department of Agriculture (USDA) to assess, on an annual basis, U.S. dependency on critical agricultural products or inputs that could be exploited in the event that China weaponizes such a dependency. USDA must submit a report to Congress on the assessment, which must include recommendations to reduce U.S. dependency on China to supply critical agricultural products or inputs. Under the bill, critical inputs include all farm management, agronomic, and field-applied production inputs (e.g., agricultural equipment, fertilizers, veterinary drugs, and seed). The bill specifies that, in conducting the assessment, USDA may not require a private entity to provide information to USDA. Further, the bill requires USDA to comply with certain confidentiality requirements and restricts disclosures of the information.
