Grain sorghum has a similar energy value to corn on a dry-matter basis but contains tannins in some varieties that can reduce digestibility in poultry and swine. Feed formulators typically apply a relative feed value discount for high-tannin sorghum and may require tannin content certification. Low-tannin or white sorghum varieties are preferred for monogastric feed and food applications.

Import volumes are generally small and episodic, arising from regional logistics advantages, short-term domestic supply shortfalls, or demand for identity-preserved non-GMO sorghum varieties. Specialty food manufacturers — particularly those producing gluten-free products — may source specific sorghum varieties internationally when domestic identity-preserved supply is insufficient.
