Michigan, USA hemp laws: quick overview

Michigan defines industrial hemp as Cannabis sativa L. with delta‑9 THC ≤0.3% dry weight, applying measurement of uncertainty (“acceptable THC level”) under MCL §333.29103 (Act 220 of 2020, effective Oct 16 2020) ([legislature.mi.gov](https://www.legislature.mi.gov/Laws/MCL?objectName=mcl-333-29103&utm_source=openai)). Growers must submit official samples 20–30 days before harvest; testing must be done by DEA‑registered labs starting Dec 31 2024 per USDA rule and MDARD guidance ([michigan.gov](https://www.michigan.gov/mdard/plant-pest/plant-health/industrial-hemp/hemp-sample-testing?utm_source=openai)). Under MCL §286.850 (Act 547 of 2014, amended), any hemp with delta‑9 THC >0.3% must be forfeited and destroyed ([legislature.mi.gov](https://www.legislature.mi.gov/Laws/MCL?objectName=mcl-286-850&utm_source=openai)). Delta‑8 THC and all THC isomers were reclassified as marijuana effective Oct 11 2021 under HB 4517, placing them under the Marijuana Regulatory Agency (now CRA) ([michigan.gov](https://www.michigan.gov/cra/resources/consumer-connection/delta-8-information?utm_source=openai)). Municipalities cannot restrict hemp businesses licensed under state law per HB 6330 §19 ([michigancannabis.org](https://michigancannabis.org/hemp?utm_source=openai)).

Shipping guidance

Inbound shipments of hemp products containing ≤0.3% THC are allowed into Michigan; business owners may legally ship hemp‑derived products into the state ([michigancannabis.org](https://michigancannabis.org/hemp?utm_source=openai)). No age verification or retailer registration is required for shipping hemp products into Michigan, though in‑state sales of intoxicating cannabinoids require CRA licensing.

Testing & COA guidance

Growers must schedule official pre‑harvest sampling 20–30 days before harvest; MDARD collects samples and tests at its Geagley Lab or other labs as needed ([michigan.gov](https://www.michigan.gov/mdard/plant-pest/plant-health/industrial-hemp/hemp-sample-testing?utm_source=openai)). After Dec 31 2024, testing must be conducted by DEA‑registered labs ([michigan.gov](https://www.michigan.gov/mdard/plant-pest/plant-health/industrial-hemp/hemp-sample-testing?utm_source=openai)). Testing reports include total delta‑9 THC and CBD percentages; noncompliant lots must be remediated or disposed ([michigan.gov](https://www.michigan.gov/mdard/plant-pest/plant-health/industrial-hemp/hemp-sample-testing?utm_source=openai)). No explicit ISO 17025 requirement found; COA retention not specified in sources.

What to buy

Hemp products with delta‑9 THC ≤0.3% dry weight: tinctures, lotions, vapes, edibles, topicals, and smokable hemp flower are legal when produced and sold by licensed entities ([michigancannabis.org](https://michigancannabis.org/hemp?utm_source=openai)).

What to avoid

Delta‑8 THC and other THC isomers are regulated as marijuana and cannot be sold without CRA licensing ([michigan.gov](https://www.michigan.gov/cra/resources/consumer-connection/delta-8-information?utm_source=openai)). Growers may not sell smokable hemp flower or finished hemp products unless licensed as processor‑handlers under Act 220 (MCL §333.29303) ([legislature.mi.gov](https://www.legislature.mi.gov/Laws/MCL?highlight=31j&objectName=mcl-333-29303&utm_source=openai)).
