Three Agencies, Three Different Jobs
Hemp operators often reference DEA, USDA, and FDA interchangeably when discussing regulatory risk, but each agency has a distinct role, and understanding the division of authority helps clarify which agency's actions actually matter for a given compliance question.
USDA: The Agricultural Regulator
USDA's authority over hemp comes directly from the 2018 Farm Bill, which tasked the agency with establishing the domestic hemp production program. USDA's role centers on: approving state and tribal hemp production plans, setting sampling and testing protocols for THC compliance at the cultivation level, licensing hemp producers under a federal plan where states haven't established their own, and managing violations related to cultivation, such as hot crops that test above the legal THC threshold.
USDA's jurisdiction is primarily focused on the growing and initial processing stage, not on finished consumer products.
FDA: The Product Safety Regulator
As covered in more detail elsewhere in this publication, FDA's authority centers on the safety and marketing of hemp-derived ingredients in food, beverages, and dietary supplements. FDA does not regulate cultivation or set THC thresholds, its jurisdiction begins where the raw agricultural product becomes a consumer product.
DEA: The Enforcement Agency for Controlled Substances
DEA's role is narrower but consequential: enforcing the Controlled Substances Act, which governs substances that fall outside the legal hemp definition. DEA's practical involvement in hemp includes: enforcement action against products that exceed legal THC thresholds and are therefore treated as marijuana rather than hemp, scrutiny of synthetic cannabinoids that fall outside the naturally derived hemp definition, and the laboratory registration requirements that were part of the November 12 framework the CR extension blocked.
DEA generally does not get involved with compliant hemp operations, its enforcement authority activates when a product crosses the line into controlled substance territory.
Where the Agencies' Roles Intersect
A single hemp product can theoretically touch all three agencies' jurisdiction at different points: USDA oversees the cultivation and initial THC compliance testing, the raw material is then processed into a consumer product falling under FDA's food/beverage/supplement authority, and if THC testing at any point reveals the product exceeds legal thresholds, DEA's controlled substance authority becomes relevant.
Why This Matters for Compliance Strategy
Understanding which agency governs which stage of your product's lifecycle helps you direct compliance resources appropriately. Cultivation and initial testing compliance should be built around USDA's framework. Finished product formulation, labeling, and marketing claims should be built around FDA's framework. And maintaining clear THC compliance documentation throughout protects against DEA's enforcement authority activating unexpectedly.
Low Gravity Hemp maintains compliance documentation addressing all three agencies' relevant jurisdiction, from cultivation-level THC testing through finished product COAs. Contact us to see how our documentation covers every stage of the regulatory chain.
