Hawaii hemp laws: quick overview

Hawaii Revised Statutes Chapter 328G (effective June 21, 2019) defines industrial hemp as Cannabis sativa L. with delta‑9 THC concentration not more than 0.3% on a dry‑weight basis (HRS §328G‑1) ([hempdata.io](https://hempdata.io/states/hawaii?utm_source=openai)). Under Hawaii Administrative Rules Chapter 11‑37 (interim rules effective December 6, 2024), manufactured hemp products must comply with per‑serving and per‑container total THC limits and are subject to lab testing, labeling, and packaging requirements ([health.hawaii.gov](https://health.hawaii.gov/medicalcannabis/statutes-and-rules/?utm_source=openai)). HAR 11‑37 also prohibits sale of smokable hemp flower, pre‑rolls, vapes, raw leaf, seed, and any products containing synthetic or isomerized cannabinoids such as delta‑8, delta‑10, HHC, THC‑O, etc. ([health.hawaii.gov](https://health.hawaii.gov/medicalcannabis/statutes-and-rules/?utm_source=openai)). Act 269 (HB 1482), signed July 2, 2025, requires retailers and distributors of manufactured hemp products to obtain a Certificate of Registration from the Office of Medical Cannabis Control and Regulation (OMCCR) by January 1, 2026; the DOH may fine non‑compliant businesses and seize products ([atlrx.com](https://www.atlrx.com/blogs/delta-9/is-delta-9-legal-in-hawaii/?utm_source=openai)).

Shipping guidance

Inbound shipments of raw hemp materials (live plants, floral material, leaf, viable seed) require submission of an HP‑1 Transportation Report to HDOA at least three business days prior to transport; processed hemp products are exempt ([dab.hawaii.gov](https://dab.hawaii.gov/hemp/?utm_source=openai)). Retailers/distributors shipping manufactured hemp products into Hawaii must hold a Certificate of Registration unless exempt (e.g., tinctures, topicals, GRAS seed products, industrial hemp) as of January 1, 2026 ([health.hawaii.gov](https://health.hawaii.gov/hempprogram/?p=507&utm_source=openai)). Age verification: hemp‑derived tinctures and other manufactured hemp products are restricted to purchasers aged 21+ ([atlrx.com](https://www.atlrx.com/blogs/delta-9/is-delta-9-legal-in-hawaii/?utm_source=openai)).

Testing & COA guidance

Under HAR 11‑37, all manufactured hemp products must undergo lab testing for total THC (sum of delta‑9 THC and THCA × 0.877) and contaminants; testing must be conducted by a qualified lab, results must be accessible via QR code or website on the label ([health.hawaii.gov](https://health.hawaii.gov/medicalcannabis/statutes-and-rules/?utm_source=openai)). ISO 17025 accreditation is implied by requirement for qualified labs but not explicitly stated; Certificate of Analysis (COA) must be retained and made available to consumers via label ([health.hawaii.gov](https://health.hawaii.gov/medicalcannabis/statutes-and-rules/?utm_source=openai)).

What to buy

Allowed products include manufactured hemp products containing naturally occurring cannabinoids in forms such as topicals (skin/hair), edibles (gummies, tablets, capsules, powders, softgels, gelcaps), oil‑based tinctures, and beverages, provided they meet THC limits and labeling/testing rules ([health.hawaii.gov](https://health.hawaii.gov/hempprogram/?p=507&utm_source=openai)).

What to avoid

Prohibited items include smokable hemp flower, pre‑rolls, raw leaf or seed, vapes, foods/beverages not in allowed forms, and any products containing synthetic or isomerized cannabinoids (delta‑8, delta‑10, HHC, THC‑O, etc.) ([health.hawaii.gov](https://health.hawaii.gov/medicalcannabis/statutes-and-rules/?utm_source=openai)).
