Tennessee HB 0403 Takes Effect, Imposing Total-THC Limit on Hemp Products
Tennessee’s HB 0403 — a 2024 hemp regulation law that imposes a total-THC limit, 21+ age-gating, and retailer licensing on consumable hemp products — took effect at the end of 2024, reshaping the state’s THCA flower market.
Nashville, Tenn. — December 26, 2024. Tennessee’s HB 0403, signed earlier in 2024, took effect with provisions that brought the state’s hemp market under a tighter regulatory framework than the federal 2018 Farm Bill baseline.
The law’s central change is its definition of “hemp-derived cannabinoid product.” Under HB 0403, products sold at retail in Tennessee must comply with a total-THC calculation rather than the federal delta-9-only threshold. The Tennessee Department of Agriculture, designated as the implementing agency, was given authority to set product-category rules and test methodologies.
In addition to the total-THC standard, HB 0403 includes:
- A 21+ age requirement for purchase of consumable hemp products.
- A retailer licensing regime administered by the state Department of Agriculture, with annual fees and renewal requirements.
- Labeling and packaging standards including child-resistant packaging, serving-size disclosures, and a prohibition on packaging designed to appeal to minors.
- A prohibition on synthetic conversion of cannabinoids — closing the in-state market for delta-8 produced via CBD-to-delta-8 chemistry.
- Tax provisions levying additional excise on hemp-derived cannabinoid products at retail.
According to Marijuana Moment and Hemp Industry Daily, implementation has been uneven. Several large national brands geofenced specific SKUs from Tennessee, while others reformulated to meet the new total-THC ceiling. Local retailers have generally complied with licensing and age-gating provisions; enforcement of the total-THC standard at point of sale has lagged behind the legal effective date.
A challenge filed by the Tennessee Growers Coalition argues that HB 0403 is preempted by federal hemp law and impermissibly burdens interstate commerce. As of this writing, the case had not produced a definitive injunction; the law remained in effect.
What it means for consumers
If you live in Tennessee, expect a narrower selection of THCA flower than was available in 2024. Brands that previously shipped raw flower with high THCA content above the new total-THC ceiling have geofenced the state. Brands with lower-THCA / higher-CBG cultivars or compliant reformulated products continue to ship.
You must be 21 to purchase. Products at brick-and-mortar Tennessee retailers should display a license number and meet packaging requirements. If a retailer can’t show licensing, that’s a compliance red flag.
