Hawaii hemp laws: quick overview

Hawaii defines “hemp” in HRS §712‑1240 (Act 14, 2020) as cannabis with delta‑9‑THC concentration not more than 0.3% on a dry‑weight basis, measured post‑decarboxylation, aligning with federal law ([data.capitol.hawaii.gov](https://data.capitol.hawaii.gov/hrscurrent/Vol14_Ch0701-0853/HRS0712/HRS_0712-1240.htm?utm_source=openai)). Under Hawaii Administrative Rules Chapter 11‑37 (interim rules, amended through Jan 28 2026), “manufactured hemp products” must contain total THC ≤ 0.3% by weight, with per‑serving limit of 1 mg and per‑container limit of 5 mg total THC; rules effective Jan 2026 ([health.hawaii.gov](https://health.hawaii.gov/hempprogram/consumers-of-mhp-faq/?utm_source=openai)). Act 263 (2023) and HRS §328G‑4 require testing protocols, labeling (including origin of hemp), and prohibit synthetic or artificially derived cannabinoids, smokable hemp, inhalable products, and non‑oral routes except topicals ([data.capitol.hawaii.gov](https://data.capitol.hawaii.gov/sessions/sessionlaws/Years/SLH2023/SLH2023_Act263.pdf?utm_source=openai)).

Shipping guidance

Inbound shipments of compliant manufactured hemp products are allowed. Retailers (including online sellers) must obtain a Certificate of Registration from DOH‑OMCCR starting January 2026 to sell hemp products ([health.hawaii.gov](https://health.hawaii.gov/hempprogram/consumers-of-mhp-faq/?utm_source=openai)). Age verification: minimum age not explicitly stated in hemp rules; general adult‑use cannabis remains illegal, but hemp‑derived delta‑9 is legal for adults (21+) per commentary ([legalclarity.org](https://legalclarity.org/is-delta-9-legal-in-hawaii-laws-limits-and-penalties/?utm_source=openai)). No special shipping restrictions beyond registration and compliance.

Testing & COA guidance

Lab testing is required for cannabinoid content (including total THC) and contaminants per Act 263 and HRS §328G‑4 ([data.capitol.hawaii.gov](https://data.capitol.hawaii.gov/sessions/sessionlaws/Years/SLH2023/SLH2023_Act263.pdf?utm_source=openai)). Rules require certification by state or independent third‑party laboratories; ISO 17025 not explicitly named but certification implied ([data.capitol.hawaii.gov](https://data.capitol.hawaii.gov/sessions/sessionlaws/Years/SLH2023/SLH2023_Act263.pdf?utm_source=openai)). Certificates of Analysis (COAs) must be available to consumers via labeling or online access ([health.hawaii.gov](https://health.hawaii.gov/hempprogram/consumers-of-mhp-faq/?utm_source=openai)).

What to buy

Allowed products: manufactured hemp products in forms of topicals (skin/hair), edibles (gummies, tablets, capsules, powders, softgels, gelcaps), oil‑based tinctures, beverages, and liquid forms ([health.hawaii.gov](https://health.hawaii.gov/hempprogram/consumers-of-mhp-faq/?utm_source=openai)).

What to avoid

Prohibited: hemp flower, leaf, seeds, pre‑rolls; vape cartridges, concentrates; foods with cannabinoids (e.g., chocolate, candies); synthetic or artificially derived cannabinoids (e.g., delta‑8, HHC, CBN); smokable hemp; inhalable products; non‑oral routes except topicals ([health.hawaii.gov](https://health.hawaii.gov/hempprogram/consumers-of-mhp-faq/?utm_source=openai)).
