NASHVILLE, Tenn. (RFD NEWS) — A pending change to the federal definition of hemp could disrupt U.S. fiber and grain hemp markets, even though those sectors are not the primary targets of the new rule. Unless delayed, the revised definition takes effect on November 12, 2026, tightening compliance standards and reshaping the broader hemp economy that supports industrial production.
The updated law shifts hemp compliance from a delta-9 THC standard to total THC, while excluding certain synthesized cannabinoids and tightening product eligibility. Although fiber and grain hemp typically test far below THC thresholds, industry leaders warn that the change could destabilize processing, financing, and infrastructure shared across hemp markets.
Fiber and grain hemp production has been rebuilding, with leading acreage in states such as South Dakota, Montana, Missouri, and parts of the Midwest. These crops support industrial uses, including animal feed, bioplastics, textiles, and construction materials, while also offering agronomic benefits such as crop rotation and soil improvement.
Concern over market disruption has prompted the introduction of the Hemp Planting Predictability Act, which would delay implementation for three years. Supporters argue the extension would protect farmers, preserve industrial investment, and allow time for clearer regulatory separation between intoxicating products and agricultural hemp.
