New Hampshire, USA hemp laws: quick overview

New Hampshire defines hemp under RSA 439‑A:2 (2019, eff. July 30 2019) as Cannabis sativa L. with Δ9‑THC ≤ 0.3 % on a dry weight basis ([gc.nh.gov](https://gc.nh.gov/RSA/html/XL/439-A/439-A-mrg.htm?utm_source=openai)). In 2023, RSA 439‑A:4 was amended (Chapter 237, Laws of 2023, eff. Oct 7 2023) to prohibit sale of hemp‑derived products containing any THC isomer variant (including Δ8, Δ9, Δ10) above 0.3 % dry weight ([gc.nh.gov](https://gc.nh.gov/RSA/html/XL/439-A/439-A-mrg.htm?utm_source=openai)). In 2026, SB 461 amended RSA 439‑A:2 to redefine hemp to include total THC (sum of Δ9 + THCA) ≤ 0.3 % dry weight; effective ~60 days after passage (likely August 2026) ([gc.nh.gov](https://gc.nh.gov/bill_status/legacy/bs2016/billText.aspx?id=1454&sy=2026&txtFormat=pdf&v=current&utm_source=openai)). Additionally, SB 485‑FN establishes a new regulatory framework under Chapter 179‑A for hemp‑derived cannabinoid products (HDCPs), including packaging, serving limits, brand registration, and child‑resistant packaging; effective January 1 2027 ([gc.nh.gov](https://www.gc.nh.gov/lsr_search/billText.aspx?id=1238&type=3&utm_source=openai)).

Shipping guidance

Inbound shipments of hemp (≤ 0.3 % Δ9‑THC) are allowed if compliant with RSA 439‑A. No specific age verification or retailer registration required for raw hemp. For hemp‑derived cannabinoid products, starting Jan 1 2027, brand registration with the Liquor Commission will be required for wholesalers and retailers under Chapter 179‑A ([gc.nh.gov](https://www.gc.nh.gov/lsr_search/billText.aspx?id=1238&type=3&utm_source=openai)).

Testing & COA guidance

Hemp growers must be licensed under RSA 433‑C and submit crop samples for THC testing at independent labs designated by the Department of Agriculture; results must be shared with licensee, commissioner, and safety commissioner ([gc.nh.gov](https://gc.nh.gov/legislation/2007/hb0424.html?utm_source=openai)). No ISO 17025 requirement specified. For HDCPs under Chapter 179‑A (effective 2027), testing requirements are not yet detailed in statute; rules to be developed by commission ([gc.nh.gov](https://www.gc.nh.gov/lsr_search/billText.aspx?id=1238&type=3&utm_source=openai)).

What to buy

Products derived from hemp with Δ9‑THC ≤ 0.3 % dry weight and total THC (Δ9 + THCA) ≤ 0.3 % are legal. Hemp‑derived CBD products meeting these thresholds are permitted ([legalclarity.org](https://legalclarity.org/is-cbd-legal-in-new-hampshire-nh-laws-and-regulations/?utm_source=openai)).

What to avoid

Avoid any hemp‑derived products containing Δ8, Δ9, Δ10, THCA, or other THC isomers above 0.3 % dry weight—these are prohibited under RSA 439‑A:4 ([nh.gov](https://www.nh.gov/liquor/enforcement/documents-reports/documents/delta9-delta8-2023-01.pdf?utm_source=openai)). Smokable hemp flower with total THC > 0.3 % is also banned. THCA is included in total THC calculation under SB 461 ([gc.nh.gov](https://gc.nh.gov/bill_status/legacy/bs2016/billText.aspx?id=1454&sy=2026&txtFormat=pdf&v=current&utm_source=openai)).
