Michigan, USA hemp laws: quick overview

Michigan defines “industrial hemp” as Cannabis sativa L. and derivatives with a delta‑9‑THC concentration of 0.3% or less on a dry‑weight basis, per MCL 333.27953 under the Michigan Regulation and Taxation of Marihuana Act, effective December 6, 2018 ([michigan.gov](https://www.michigan.gov/-/media/Project/Websites/mdard/documents/pesticide-plant-pest/hemp/MDARD-Hemp-Production-Plan.pdf?rev=d8b106947ded4468aede817236b8a86c&utm_source=openai)). Public Act 220 of 2020 (Industrial Hemp Growers Act), effective October 16, 2020, requires growers to register with MDARD and mandates pre‑harvest sampling and testing; non‑compliant lots must be remediated or destroyed ([archive.legislature.mi.gov](https://archive.legislature.mi.gov/documents/mcl/archive/2021/March/mcl-Act-220-of-2020.pdf?utm_source=openai)). Delta‑8 THC and other hemp‑derived intoxicating cannabinoids were reclassified as marijuana under Public Act 56 of 2021, effective October 11, 2021, placing them under MRA regulation ([michigan.gov](https://www.michigan.gov/cra/resources/consumer-connection/delta-8-information?utm_source=openai)).

Shipping guidance

Inbound shipments of hemp into Michigan must comply with federal and state THC limits. Growers must be registered with MDARD; processors must hold a Hemp Processor‑Handler license from the Cannabis Regulatory Agency (CRA) to receive or ship processed hemp products ([michigan.gov](https://www.michigan.gov/cra/sections/hemp-processing/hemp-processing-faqs?utm_source=openai)). Age verification is not specified for hemp shipments, but delta‑8 and similar cannabinoids require MRA licensing and adult‑use restrictions apply.

Testing & COA guidance

MDARD requires official pre‑harvest sampling by trained inspectors; samples tested at MDARD’s Geagley Laboratory with certified reports before harvest (PA 220 of 2020) ([michigan.gov](https://www.michigan.gov/mdard/-/media/Project/Websites/mdard/documents/pesticide-plant-pest/hemp/tech_bulletin_preharvest_sampling_process.pdf?hash=84297F94973DAD6335354C4835550569&rev=366edf532f3c46c690157c3140738e00&utm_source=openai)). Labs must be DEA‑registered as of December 31, 2022, per USDA-aligned rules ([michigan.gov](https://www.michigan.gov/mdard/plant-pest/plant-health/industrial-hemp/resources?utm_source=openai)). Certificate of Analysis must accompany compliant lots; growers must retain records. No explicit ISO 17025 requirement stated.
