What Are Hemp Industry Regulations?
Hemp is federally legal in the U.S. under the 2018 Farm Bill if it contains no more than 0.3% delta-9 THC on a dry-weight basis. Hemp industry regulations set the guardrails for licensing, crop testing, remediation, transport, processing, and labeling.
These rules protect consumers and keep supply chains consistent. They also reduce legal risk for growers, processors, and brands operating in a complex, state-by-state framework.
Who Regulates Hemp in the U.S.?
- USDA sets national standards for cultivation under approved state and tribal plans, including sampling and testing rules.
- States and Tribes run their own approved programs: licensing, inspections, reporting, and enforcement vary by jurisdiction.
- FDA oversees food, dietary supplements, cosmetics, and drug claims. As of today, CBD cannot be lawfully marketed as a dietary supplement or added to conventional food under federal law.
- DEA enforces controlled substances law and is tied to the lab registration requirement for hemp testing.
- EPA regulates pesticides under FIFRA and the Worker Protection Standard; only approved products may be used on hemp.
- OSHA governs workplace safety for farms, processors, and labs.
- FinCEN and Banks provide banking guidance; banks may require documentation to demonstrate legal hemp activity.
State vs. Federal Hemp Industry Regulations
Federal law sets the floor; state or tribal plans add detail. Always follow the most stringent applicable rule. For example, your state may require more frequent sampling, specific label elements, or tighter recordkeeping than USDA.
Licensing & Registration: Start Here
Before you plant or process, make sure you’re legally covered. A straightforward approach reduces delays and audit risk.
- Choose your jurisdiction. Confirm whether you’ll operate under a state/tribal plan or the USDA plan (for jurisdictions without approved plans).
- Apply for licenses. Submit grower, handler/processor, and (if applicable) nursery licenses. Expect maps, GPS coordinates, legal descriptions, and fees.
- Background checks. Most plans require that key participants have no disqualifying felony drug convictions within the last 10 years.
- Register lots and varieties. Identify each lot/field/greenhouse and intended cultivars; keep seed certificates or clone provenance.
- Compliance plan. Draft SOPs for sampling, testing, pesticide use, sanitation, and recall. This satisfies audits and trains staff.
- Insurance and contracts. Secure crop insurance where available, and add quality specs in supply contracts (THC limits, sampling windows, remediation rights).
- Recordkeeping system. Implement a system to track lots from planting through sale. Keep records for at least three years (or longer if required).
Pre-Harvest Sampling and THC Testing
Passing pre-harvest testing is central to farming compliance. Here’s what to expect under the USDA final rule and most state plans:
- Sampling window: Typically within 30 days before harvest.
- Sampling method: Collected by an authorized sampler using plan-approved procedures, often flower/top third cuttings.
- Lab requirements: Labs must test for total delta-9 THC (including THCA via decarboxylation or equivalent). The USDA final rule requires DEA-registered labs; enforcement has been periodically extended—confirm current status with your state and USDA.
- Measurement uncertainty: Labs report THC with an uncertainty range; a result is compliant if the top of the range does not exceed 0.3% (plan-specific).
Best practice: stagger plantings, use day-length appropriate genetics, and monitor cannabinoid development so you harvest before THC exceeds limits.
Handling Non-Compliant (“Hot”) Crops
If your crop tests above 0.3% total THC:
- Negligence threshold: Many plans treat results below 1.0% as a negligent violation, not a criminal matter (subject to corrective action).
- Remediation: Some programs allow shredding and re-testing or removing and testing fiber material only. Follow your plan’s procedures exactly.
- Disposal: If remediation fails or is not allowed, disposal must follow plan-approved methods and be documented.
- Corrective actions: Update SOPs, genetics, and sampling timing to prevent repeat issues.
Processing, Manufacturing, and Labeling Rules
Processor and brand compliance focuses on safety, traceability, and truthful marketing aligned with industry standards:
- Facility compliance: Follow cGMPs (21 CFR Parts 111/117 as applicable), sanitation, pest control, and allergen controls.
- Labeling: Include product identity, net contents, ingredients, manufacturer info, batch/lot number, and a scannable COA/QR code where required by your state.
- Claims: Avoid disease or drug claims. Structure/function style statements must be truthful, not misleading, and substantiated.
- CBD status: FDA’s current position is that CBD cannot be marketed as a dietary supplement or added to conventional foods under federal law. States may allow certain products; federal law still applies.
- Hazards and testing: Implement a risk-based testing plan (potency, residual solvents, heavy metals, pesticides, microbes, mycotoxins, and stability for shelf life).
Transportation, Recordkeeping, and Reporting
Interstate transport of compliant hemp is protected under the Farm Bill. However, documentation must be airtight to satisfy hemp oversight and law enforcement checks.
- Documents to carry: Copy of license, pre-harvest COAs, shipping manifest, and invoices with lot identifiers.
- Interstate movement: States cannot prohibit transit of lawful hemp; still, follow state-specific notices or stop requirements.
- Reporting: Many plans require acreage reports, harvest reports, and disposal reports within set timeframes.
- Retention: Keep all records (seed-to-sale) for at least three years.
Common Pitfalls and How to Avoid Them
- Planting genetics not suited to your latitude, causing THC spikes.
- Missing the sampling window or using an unapproved sampler.
- Relying on a non-DEA lab when your plan still requires DEA registration.
- Inadequate pesticide documentation and WPS training.
- Marketing products with disease claims or missing COAs.
- Weak traceability, making recalls or audits painful.
Real-World Example: Cutting Compliance Risk by 80%
In 2023, a 60-acre Colorado farm failed two pre-harvest tests after an unusually hot August. The team paused harvest, swapped to earlier-flowering genetics for the next cycle, and installed weekly in-house potency checks on sampled tops starting week six. They also tightened irrigation and nitrogen in late flower to reduce stress-related THC rises.
Results the following season: zero hot lots, harvest COAs averaging 0.21% total THC, and an 80% drop in re-sampling costs. Their updated farming compliance SOPs (genetics selection, staged harvest plan, and lab scheduling) made the difference.
Practical, Step-by-Step Compliance Plan
- Map fields/rooms and register lots with your regulator.
- Select region-appropriate genetics with verified COAs.
- Train staff on sampling, sanitation, and pesticide safety.
- Schedule pre-harvest sampling 20–25 days before target harvest; adjust based on in-house monitoring.
- Use authorized samplers and confirm lab capacity and requirements.
- Prepare remediation and disposal SOPs before you need them.
- Implement cGMPs for processing with batch records and CAPA logs.
- Build labels and COAs to meet state rules; verify claims and substantiation.
- Assemble a shipping packet: license, manifests, COAs, and invoices.
- Audit quarterly against your plan; document findings and fixes.
Tools and Templates
- Sampling checklist and chain-of-custody form
- Lot traceability spreadsheet or seed-to-sale software
- Labeling checklist aligned to your state
- Supplier qualification questionnaire (for labs, extractors, and co-packers)
- Internal audit template and corrective action log
Conclusion
With a clear plan and verified SOPs, you can navigate hemp industry regulations confidently, pass audits, and protect your brand. Focus on genetics, timely sampling, validated labs, and transparent labeling to minimize risk and maximize market access.
FAQs
What does the 0.3% THC limit actually mean?
Regulators use total delta-9 THC (including THCA via decarboxylation or equivalent). If the reported value plus measurement uncertainty exceeds 0.3% on a dry-weight basis, the lot is non-compliant under most plans.
How is hemp different from marijuana in the eyes of the law?
Legally, hemp is cannabis with no more than 0.3% delta-9 THC by dry weight. Marijuana exceeds that threshold and remains a Schedule I substance under federal law.
Do I need a DEA-registered lab for testing?
The USDA final rule requires DEA-registered labs; enforcement has been extended at times due to lab capacity. Check your state plan and the latest USDA notices before sampling.
How long should I keep records?
Keep lot, sampling, test, and sales records for at least three years, or longer if your state or contracts require it.
Can I ship hemp across state lines?
Yes, compliant hemp can move interstate under the Farm Bill. Carry your license, COAs, manifests, and invoices to streamline law enforcement checks.
