Kansas Hemp Laws: Licensing, Testing, and Penalties

Kansas hemp laws now split responsibility between two governments: since January 1, 2025, hemp producer licenses are issued by the USDA rather than the Kansas Department of Agriculture, while Kansas keeps its own rules on prohibited products, processor registration, and inspections. The state still defines hemp as cannabis with no more than 0.3% delta-9 THC on a dry weight basis, but a federal amendment signed in November 2025 will replace that with a broader total-THC standard about a year later. If you grow, process, or move hemp in Kansas, both layers apply to you.

How Kansas Defines Hemp

Under the Kansas Commercial Industrial Hemp Act, industrial hemp is all parts and varieties of Cannabis sativa L., whether growing or not, containing a delta-9 THC concentration of no more than 0.3% on a dry weight basis.¹ That matches the federal standard set by the 2018 Farm Bill.² Anything above 0.3% is treated as marijuana, which is illegal in Kansas.

For hemp products rather than raw plant material, the concentration is measured on a percentage-by-weight basis rather than dry weight.¹ Which method applies affects which products clear a compliance check.

The Total THC Standard Coming in Late 2026

A federal law signed on November 12, 2025, changes the hemp definition to a total-THC standard. Total THC includes THCA, delta-8 THC, delta-10 THC, and THCO, and the 0.3% ceiling is measured against that combined figure.² The amendment takes effect 365 days after enactment, placing the transition in late 2026.³

This is a real tightening. Varieties that currently pass a delta-9-only test can fail a total-THC test because THCA, which converts to THC when heated, is counted. Kansas Senate Bill 292, introduced in the 2025 session, would keep the delta-9-only standard at the state level, but federal requirements still apply to any producer licensed through the USDA program.⁴ The FDA has 90 days from enactment to publish lists of naturally occurring cannabinoids, THC-class cannabinoids, and cannabinoids with THC-like effects, and those lists will shape how the new rule works in the field.³ USDA has indicated it is delaying enforcement of certain requirements through December 31, 2026.⁵

Getting a License to Grow

Kansas producers apply for and receive a hemp license from the USDA before planting.⁶ Applications go through the USDA’s Hemp eManagement Platform (HeMP) and are accepted on a rolling basis, so there is no annual deadline.⁵ A USDA license is valid through December 31 of the third year after the year it was issued.

Every applicant must pass a criminal background check. Anyone convicted of a felony related to a controlled substance within the past ten years is ineligible under the 2018 Farm Bill.⁶ The application also requires GPS coordinates and a map for each field or lot where hemp will be grown.

The KDA still monitors production. State law authorizes it to maintain land records for hemp sites, conduct annual inspections of a random sample of producers, and set procedures for testing and disposal of non-compliant crops.⁷ Expect oversight from both agencies.

Sampling, Testing, and Harvest

Every hemp lot and every producer must be sampled and tested before harvest. A trained sampling agent collects samples within 30 days before the anticipated harvest date. Producers cannot sample their own crop.⁸ The protocol is designed to achieve 95% confidence that no more than 1% of plants in the lot exceed the acceptable THC threshold.

Harvest must be completed within 30 days of sample collection.⁸ Under Kansas administrative regulations, a licensee may not harvest until receiving notice that test results show delta-9 THC below 0.3%.⁹ In practice you wait for clearance, then move quickly.

All labs doing USDA-program testing must be registered with the DEA.⁸ You can send samples to a private lab at any time for your own information, but private results do not substitute for the official program test, and you pay for those out of pocket.⁹ Testing typically runs $75 to $750 per sample depending on the lab and analysis.

When a Crop Tests Hot

A failed test does not automatically destroy your entire crop. The USDA program offers two remediation paths before disposal.

The first is to separate and remove all flowers, buds, and floral material from the stalks, leaves, and seeds. The floral material must be destroyed, but the remaining plant parts can potentially be used. The second is to shred the entire lot into a uniform biomass, then resample and retest. If the biomass passes, it can enter commerce. If it fails again, it must be destroyed.¹⁰

When disposal is required, approved methods include plowing under, composting, disking, bush mowing, deep burial, and burning. The producer pays all costs of resampling, remediation, and disposal, must notify the licensing authority of the chosen path, and must submit documentation proving completion. Inspectors can review those records during normal business hours. One detail catches growers off guard: seeds recovered from non-compliant hemp during remediation cannot be used for replanting.¹⁰

Penalties for Violations

Federal Negligent Violations

A negligent violation happens when a producer fails to comply without intent. Common examples include growing a crop that tests above 0.3% despite reasonable efforts, or missing a required report. For each negligent violation, USDA issues a Notice of Violation and requires a corrective action plan spelling out the fix, the deadline, and how compliance will be shown. Corrective action plans remain in place for at least two years.¹¹

A second negligent violation while a plan is already in effect requires a new plan with stricter quality-control measures and staff training. Three negligent violations within a five-year period trigger license revocation, and the producer becomes ineligible to grow hemp for five years from the date of the third violation.¹¹

Kansas Sanctions

Kansas administrative regulations separately list violations that can bring license revocation and denial of future applications, including growing cannabis over 0.3% THC, refusing inspections, and failing to pay assessed fees.¹² If a crop must be destroyed for exceeding the THC limit, the producer pays.

For prohibited hemp products, Kansas imposes criminal penalties. A first conviction for manufacturing, selling, or distributing a prohibited hemp product is a Class A nonperson misdemeanor. A second or later conviction is a severity level 9 nonperson felony.¹³ The criminal track applies to product violations, not to a field crop that simply tests hot.

Prohibited and Restricted Hemp Products

Kansas bans several hemp product categories outright. The following may not be manufactured, sold, or distributed in the state:

Cigarettes, cigars, and chew or dip containing hemp
Liquids, solids, or gases containing hemp intended for use in vaporizing devices
Hemp teas
Any hemp product intended for human or animal consumption containing an ingredient banned under the Kansas Food, Drug and Cosmetic Act or the Commercial Feeding Stuffs Act

CBD oil is expressly carved out from that last restriction and may still be used as an ingredient in hemp products.¹⁴

A second category is restricted rather than banned. Hemp buds, ground floral material, ground leaf material, and any hemp extract above 0.3% delta-9 THC that will be further processed may only be sold to someone holding a KDA cultivation license or registered as a hemp processor.¹⁴ Selling those materials outside the licensed industry carries the same misdemeanor and felony penalty tiers.

Processor Registration Through the State Fire Marshal

Growing hemp and processing hemp require separate authorizations. In Kansas the State Fire Marshal handles processor registration, not the KDA or USDA. A processor is anyone who accepts harvested hemp plants and dries, grinds, separates, or extracts cannabinoids from them.¹⁵

Annual registration fees depend on the work performed:

$1,000 per year for processors that extract cannabinoids or process extracted cannabinoids
$500 per year for processors that only dry, grind, or separate plant parts without extraction

Registrations expire June 30 each year, renewal applications are due by June 1, and fees are nonrefundable. Every employee involved in hemp processing must pass a background check, and the facility must meet building code requirements reviewed by the Fire Marshal’s office.¹⁵ A processor whose Kansas registration is revoked cannot reapply for three years from the date of revocation.¹⁶

Moving Hemp Across State Lines

The 2018 Farm Bill protects the interstate movement of legally produced hemp. No state or tribal territory may prohibit the transportation or shipment of hemp or hemp products produced in compliance with the federal program.¹⁷ Some states still impose their own documentation or inspection rules on shipments passing through, so the federal shield is not a guarantee of a smooth trip.

At a minimum, any shipment should travel with a certificate of analysis from a USDA-approved lab confirming THC concentration, a copy of the producer’s or distributor’s license, and a bill of lading. Some states require advance permits or enclosed vehicles for hemp transport, so check the rules of every state along the route before shipping.

Inspections and Records

Kansas and federal regulations both require detailed records and broad inspector access. Each licensee must allow the KDA to reach all land identified for hemp cultivation and all records related to hemp production, including seed acquisition, planting dates, harvest dates, and testing documentation. Inspectors have unrestricted access to growing areas, adjacent areas, buildings, motor vehicles, and other structures used for hemp activities, with or without advance notice.¹⁸

Licensees also consent to KDA sharing information about their operations, including GPS coordinates, with the USDA, the Kansas Bureau of Investigation, the DEA, and other law enforcement agencies.¹⁸ At the federal level, every licensee’s premises and records are subject to at least one annual inspection.

What’s Changing at the State Level

Senate Bill 292, introduced in the 2025 session, would expand the definition of industrial hemp to explicitly include derivatives, extracts, cannabinoids, isomers, acids, and salts, while keeping the delta-9 THC threshold at 0.3% on a dry weight basis. It would also update the list of prohibited hemp products and require that no seed or clone be considered authorized unless it meets USDA-adopted standards.⁴ Between SB 292 at the state level and the total-THC transition federally, growers who evaluate their genetics and testing arrangements ahead of the 2026 season will have room to adjust; those who wait may find themselves scrambling.
