Michigan, USA hemp laws: quick overview

Michigan’s Industrial Hemp Growers Act (Public Act 220 of 2020, as amended by Act 4 of 2021, effective March 24, 2021) establishes that hemp must not exceed the “acceptable THC level,” defined as total delta‑9‑THC ≤ 0.3% on a dry‑weight basis, aligning with federal law ([sfa.senate.michigan.gov](https://sfa.senate.michigan.gov/Publications/Notes/2026Notes/NotesWin26jm.pdf?utm_source=openai)). Growers must register with MDARD; sampling by MDARD inspectors must occur 20–30 days before harvest, and growers must harvest within 30 days of sampling ([michigan.gov](https://www.michigan.gov/mdard/plant-pest/plant-health/industrial-hemp/hemp-sample-testing?utm_source=openai)). Testing must be conducted by MDARD’s Geagley Laboratory or DEA‑registered third‑party labs that are ISO 17025 accredited and use post‑decarboxylation methods, report measurement of uncertainty, and avoid sample commingling ([michigan.gov](https://www.michigan.gov/mdard/-/media/Project/Websites/mdard/documents/pesticide-plant-pest/hemp/MDARD-Hemp-Production-Plan.pdf?hash=D78465A76EC379FFE90BCCDC3F8EB506&rev=9737f64416484518b613423b6f622711&utm_source=openai)). If total delta‑9‑THC exceeds 0.3%, the lot must be remediated or destroyed under section 4 07; negligent violations (≤1.0% THC) trigger corrective action plans, while intentional violations are penalized under section 602 ([law.justia.com](https://law.justia.com/codes/michigan/chapter-333/statute-act-220-of-2020/division-220-2020-vi/section-333-29602/?utm_source=openai)).

Shipping guidance

Inbound shipments of hemp products are allowed provided they comply with federal Δ9‑THC ≤ 0.3% dry‑weight. No specific Michigan statute prohibits shipping; however, growers must be registered with MDARD, and processors must hold a Hemp Processor‑Handler license from the Cannabis Regulatory Agency (CRA) ([michigan.gov](https://www.michigan.gov/mdard/plant-pest/plant-health/industrial-hemp?utm_source=openai)). Age verification is not specified for hemp products. Retailer registration is required for growers and processors.

Testing & COA guidance

Michigan requires official regulatory testing by MDARD’s Geagley Lab or DEA‑registered, ISO 17025‑accredited third‑party labs using post‑decarboxylation total delta‑9‑THC methods, reporting measurement of uncertainty and avoiding sample commingling ([michigan.gov](https://www.michigan.gov/mdard/-/media/Project/Websites/mdard/documents/pesticide-plant-pest/hemp/MDARD-Hemp-Production-Plan.pdf?hash=D78465A76EC379FFE90BCCDC3F8EB506&rev=9737f64416484518b613423b6f622711&utm_source=openai)). MDARD charges $150 per sample for sampling and $150 per sample for testing as of January 1, 2026 ([michigan.gov](https://www.michigan.gov/mdard/plant-pest/plant-health/industrial-hemp?utm_source=openai)). Certificate of analysis must be provided to grower and department.

What to buy

Products compliant with Michigan law include hemp-derived products with total delta‑9‑THC ≤ 0.3% dry‑weight, such as CBD oils, edibles, hulled hemp seed, hemp protein powder, hemp seed oil (GRAS ingredients), and other non‑intoxicating forms processed by licensed entities ([michigan.gov](https://www.michigan.gov/mdard/plant-pest/plant-health/industrial-hemp?utm_source=openai)).

What to avoid

Avoid products exceeding total delta‑9‑THC > 0.3% dry‑weight. Forms not explicitly addressed—such as delta‑8, delta‑10, THCa, HHC—are “unknown” under Michigan law. Smokable hemp flower is not banned by statute but must comply with THC limits; if over limit, must be remediated or destroyed.

How to shop compliant, tested hemp

  • Michigan follows federal Δ9‑THC ≤ 0.3% dry‑weight baseline
  • Michigan requires DEA‑registered labs and ISO 17025 accreditation for official testing
  • Growers must register with MDARD and processors with CRA
  • Sampling must occur 15–30 days pre‑harvest; remediation/disposal required if over limit
