Hemp Regulation Guide: U.S. Laws for Growing & Selling Hemp

Thinking about hemp as a crop or product line? This hemp regulation guide explains, in plain English, the U.S. rules you must follow to grow and sell hemp without risking fines or crop loss. You’ll learn the federal framework, how state plans work, what to put on labels, and the steps to get licensed fast.

Hemp Regulation Guide: U.S. Compliance at a Glance

• Hemp is federally legal if it contains no more than 0.3% delta‑9 THC on a dry-weight basis.
• Growers must be licensed under a State/Tribal plan approved by USDA or under the USDA plan where no state plan exists.
• Pre-harvest sampling and lab testing are mandatory; non-compliant crops must be remediated or destroyed.
• FDA regulates ingestible products (like CBD foods and dietary supplements); state rules vary widely.
• Interstate transport of lawful hemp and seeds is protected, but products still must meet the destination state’s rules.

Federal Laws That Shape Hemp

The 2018 Farm Bill removed hemp from the Controlled Substances Act if it meets the 0.3% delta‑9 THC limit. USDA oversees production. FDA regulates how ingestible products are marketed. States and Tribes can set additional requirements.

Core federal pillars

• USDA Production Rule: Requires producer licensing, background checks for “key participants,” pre-harvest sampling within 30 days, and testing of total delta‑9 THC (including THCA by post‑decarboxylation methods). Negligence threshold is generally at 1.0% THC.
• DEA-Registered Labs: USDA’s final rule requires DEA-registered labs for official testing; enforcement of this requirement has been temporarily delayed at times. Check current USDA notices before harvest.
• Acceptable Hemp THC Level: Labs report a measurement of uncertainty. If the result’s lower bound is at or below 0.3%, it may be considered compliant.
• Interstate Commerce: States cannot block lawful hemp shipments, but destination-state product rules apply.
• FDA & FTC: As of 2024, CBD cannot be marketed as a dietary supplement or added to conventional food at the federal level. Disease-treatment claims are prohibited. Many states allow CBD foods under their own laws—check both.

Step-by-Step: How to Get Licensed to Grow Hemp

1. Check your state or tribal plan. Find your Department of Agriculture (or Tribal authority) hemp page. If your state lacks a plan, you can apply under the USDA plan.
2. Apply for a producer license. Submit IDs for all “key participants,” maps with GPS coordinates of each growing area, and consent to inspections.
3. Clear the background check. Most felony drug convictions within 10 years disqualify key participants (with narrow exceptions).
4. Report acreage to FSA. After planting, report fields to USDA’s Farm Service Agency within required timelines.
5. Plan sampling and testing. Schedule state-approved samplers 15–30 days (state-specific) prior to harvest; use a DEA‑registered lab if required.
6. Harvest and records. Harvest within the allowed window after sampling. Keep certificates of analysis (COAs), shipping docs, and disposal/remediation records for audits.

THC Testing, Sampling, and Remediation

Compliant testing is the backbone of hemp farming laws. Get sampling right to avoid costly surprises.

• Sampling Window: Typically within 30 days before harvest. Some states differ; always confirm your plan’s timing.
• Representative Samples: Flowering tops from multiple plants and locations in the lot, per your plan’s protocol.
• Total THC: Labs must measure delta‑9 THC plus THCA conversion to reflect total potency.
• Non-Compliant Lots: If above 0.3% THC, states may allow remediation by removing and destroying flowers and retaining stalks/grain, or homogenizing and retesting. Lots exceeding 1.0% THC may trigger negligence violations.
• Paper Trail: Keep COAs, sampling forms, and any corrective action plans for inspector review.

Hemp Business Rules for Processing and Selling

Rules shift when you move from farming to products. Here’s how to stay compliant when launching SKUs or selling wholesale.

Product categories and who regulates what

• Raw plant material: Governed by USDA production rules and state transport rules; keep COAs handy.
• Ingestibles (oils, gummies, beverages): FDA says CBD is not a lawful dietary ingredient in foods or supplements federally. Some states allow CBD foods with specific labeling, testing, and registration. Comply with both state and FDA enforcement policies.
• Topicals and cosmetics: Allowed if no drug claims and product is safe. Follow cosmetic labeling rules.
• Vape and inhalable products: Highly state-specific; many restrict or ban. Age-gating (often 21+) is common.
• Intoxicating hemp derivatives (e.g., delta‑8, delta‑10): Laws vary widely; many states restrict or ban. Vet every destination state before sale or shipment.

Labeling best practices (state rules vary)

• Common requirements include product name, net quantity, batch/lot, ingredient list, manufacturer/packer info, and a QR code linking to a recent COA.
• Avoid disease-treatment claims; structure/function claims can still draw scrutiny.
• Use age warnings and keep products child-resistant where required.
• For ingestibles, follow food or dietary supplement Good Manufacturing Practices (cGMPs) as applicable under state law.

Shipping and e-commerce

• Interstate shipping of lawful hemp is protected, but products must meet the destination state’s standards.
• Keep a copy of your hemp license and the product’s COA with shipments.
• Age-gate your website for restricted products; use accurate weight and cannabinoid content on listings.

Banking, Taxes, and Insurance

• Banking: FinCEN allows banking for lawful hemp businesses. Provide licenses, COAs, and compliance docs. Expect enhanced due diligence.
• Taxes: Hemp is not subject to 280E (it applies to Schedule I/II substances), but standard federal and state taxes apply. Some states impose excise taxes on certain hemp products.
• Insurance: USDA’s Risk Management Agency offers programs like Whole-Farm Revenue Protection and, in select counties, Multi-Peril Crop Insurance for fiber/grain hemp. Check Noninsured Crop Disaster Assistance Program (NAP) for areas without MPCI.

Experience: A Real-Life Example

Maya, a fifth-generation farmer in Kentucky, switched five acres from tobacco to hemp fiber. She applied under the state plan, cleared the background check, and mapped her fields with GPS. Thirty days before harvest, she booked a sampler, used a DEA‑registered lab per state guidance, and her total THC tested at 0.19%. She attached COAs to each bale for transport to a regional decorticator.

For a side business, Maya explored CBD pet tinctures. She learned that while Kentucky permits certain hemp extracts, FDA does not allow CBD as a dietary supplement. She pivoted to hemp seed oil topicals and fiber-based products, which carried lower legal risk and simpler labeling. The shift kept her compliant and profitable.

State Check: How to Verify Your Local Rules

State hemp programs add requirements on top of federal law. Before planting or selling, confirm:

• License types (producer, processor, retailer) and fees
• Sampling windows and approved samplers
• Allowable product forms and age limits
• Label elements and COA timing (e.g., within 12 months)
• Rules for delta‑8 and other isomers

Search “[Your State] Department of Agriculture hemp program” or your Tribal authority’s site. This helps you align with your state’s hemp farming laws without guesswork.

Common Mistakes to Avoid

• Planting without a final license approval
• Missing the sampling window or using a non-approved sampler
• Assuming CBD foods are federally authorized
• Shipping intoxicating hemp products into states that ban them
• Poor recordkeeping: missing COAs, field maps, or disposal logs

Quick Compliance Checklist

• Active producer license and background checks on file
• Fields mapped with GPS and reported to FSA
• Sampling scheduled 15–30 days pre-harvest
• COAs showing total delta‑9 THC ≤ 0.3% (with MOE)
• Remediation/disposal plan for hot crops
• Product labels with QR-linked COAs and no disease claims
• Shipping docs and age-gating for restricted products
• Banking, tax, and insurance set up

Using this Hemp Regulation Guide for Your Operation

Start with licensing, then design your harvest/testing calendar, and finally build product labels and SOPs that match both your state rules and FDA/FTC expectations. Update these steps each season.

Conclusion

Hemp can be a resilient crop and a strong product category if you treat compliance as a system. Use this hemp regulation guide to license properly, test on time, label clearly, and ship only into states that allow your products. When in doubt, ask your state program or a qualified attorney before you plant or launch.
