Massachusetts, USA hemp laws: quick overview

Massachusetts General Laws Chapter 128, Section 116 (as amended by Chapter 55 of the Acts of 2017) defines hemp as cannabis with a delta‑9‑THC concentration not exceeding 0.3 % on a dry‑weight basis; this aligns with the 2018 Farm Bill baseline and is enforced via MDAR’s regulation 330 CMR 32.00, effective August 5, 2022, which governs licensing, testing, and certification of hemp production ([mass.gov](https://www.mass.gov/guides/hemp-in-massachusetts-faqs?utm_source=openai)). Massachusetts does not impose a separate state total‑THC percentage or per‑serving limit beyond the federal 0.3 % Δ9‑THC threshold; no statute or regulation establishing a lower or additional limit could be found ([mass.gov](https://www.mass.gov/guides/hemp-in-massachusetts-faqs?utm_source=openai)). In December 2022, MDAR issued guidance under M.G.L. c.128 §117 clarifying that synthetically derived cannabinoids such as delta‑8 THC remain controlled substances and are prohibited from sale or manufacture in the Commonwealth ([mass.gov](https://www.mass.gov/doc/delta-8-thc/download?utm_source=openai)).

Shipping guidance

Inbound shipments of hemp and hemp‑derived products are allowed if sourced from producers licensed under USDA or a USDA‑approved state plan; MDAR requires licensing and compliance with 330 CMR 32.00 for processing and cultivation ([mass.gov](https://www.mass.gov/guides/hemp-in-massachusetts-faqs?utm_source=openai)). There is no specific age‑verification requirement for hemp shipments under state law. Retailer registration is required: any grower or processor must hold a valid MDAR license.

Testing & COA guidance

Massachusetts requires testing of hemp crops prior to harvest to ensure Δ9‑THC ≤ 0.3 % dry weight, under 330 CMR 32.00; remediation and disposal protocols apply if over limit ([mass.gov](https://www.mass.gov/guides/hemp-in-massachusetts-faqs?utm_source=openai)). The regulation does not explicitly mandate ISO/IEC 17025 accreditation, but certification of hemp for production is required. COA retention and specific panel requirements are not detailed in publicly available MDAR guidance.

What to buy

Non‑intoxicating hemp products containing ≤ 0.3 % Δ9‑THC by dry weight are legal, including CBD, hemp seed oil, fiber, and other derivatives compliant with federal and state definitions ([mass.gov](https://www.mass.gov/guides/hemp-in-massachusetts-faqs?utm_source=openai)).

What to avoid

Avoid hemp‑derived intoxicating cannabinoids such as delta‑8 THC, THCA, and other synthetically derived THC isomers—they are prohibited outside the regulated cannabis system ([mass.gov](https://www.mass.gov/doc/delta-8-thc/download?utm_source=openai)).
