New Hampshire, USA hemp laws: quick overview

New Hampshire defines “hemp” under RSA 439‑A:2 as Cannabis sativa L. with delta‑9‑THC not more than 0.3 % on a dry weight basis; this definition took effect July 30, 2019 ([gc.nh.gov](https://www.gc.nh.gov/rsa/html/XL/439-A/439-A-mrg.htm?utm_source=openai)). A 2026 amendment (SB 461) clarifies that “total THC” includes all THC including THCA ([gc.nh.gov](https://gc.nh.gov/bill_status/legacy/bs2016/billText.aspx?id=1454&sy=2026&txtFormat=html&v=SA&utm_source=openai)). Under RSA 439‑A:4, effective October 9, 2023, the sale of hemp‑derived products containing natural or synthetic THC greater than 0.3 % dry weight—including delta‑8, delta‑9, THCA, or any THC isomer—is prohibited ([gc.nh.gov](https://www.gc.nh.gov/rsa/html/XL/439-A/439-A-mrg.htm?utm_source=openai)). SB 624‑FN (2026) further restricts hemp‑derived cannabinoid products by imposing a per‑container total THC limit of 0.4 mg, raising the purchase age to 21, and excluding non‑compliant products from the hemp definition with associated penalties ([gc.nh.gov](https://gc.nh.gov/bill_status/legacy/bs2016/billText.aspx?id=1418&sy=2026&txtFormat=html&v=SA&utm_source=openai)).

Shipping guidance

Inbound shipments of hemp products are allowed only if compliant with state THC limits (≤ 0.3 % Δ9‑THC dry weight and ≤ 0.4 mg total THC per container). Age verification at delivery is required for hemp‑derived THC products (must be 21+). Retailers must ensure products meet RSA 439‑A and SB 624‑FN requirements; no separate retailer license beyond standard agricultural or food regulations is specified.

Testing & COA guidance

Lab testing is required: products must be tested to confirm Δ9‑THC ≤ 0.3 % dry weight and total THC including THCA ≤ 0.3 % dry weight. Laboratories must be certified by the Department of Agriculture under RSA 146:22 (HB 1581‑FN, 2020) ([gc.nh.gov](https://www.gc.nh.gov/bill_status/legacy/bs2016/billText.aspx?id=1559&sy=2020&txtFormat=html&utm_source=openai)). Certificates of analysis (COAs) should be retained to demonstrate compliance; no ISO 17025 requirement is specified in statute.

What to buy

Products with Δ9‑THC ≤ 0.3 % dry weight and total THC ≤ 0.3 % dry weight, and total THC per container ≤ 0.4 mg; non‑intoxicating hemp products such as CBD, fiber, seed oil, food, textiles, etc., compliant with RSA 439‑A and RSA 146:22.

What to avoid

Any hemp‑derived product exceeding 0.3 % THC dry weight (including delta‑8, delta‑9, THCA, or other isomers), or exceeding 0.4 mg total THC per container; products sold to persons under 21; non‑certified lab tested products.
