Ineligible Commodities

Commodities that did not suffer a five percent-or-greater price decline from mid-January 2020 to mid-April 2020 are not eligible for CFAP. Specifically, this includes sheep more than two years old, eggs/layers, soft red winter wheat, hard red winter wheat, white wheat, rice, flax, rye, peanuts, feed barley, Extra Long Staple (ELS) cotton, alfalfa, forage crops, hemp, and tobacco. USDA may reconsider the excluded commodities if credible evidence is provided that supports a five percent price decline.
