Hawaii hemp laws: quick overview

Hawaii aligns with the 2018 Farm Bill’s definition of hemp (Δ9‑THC ≤ 0.3% dry weight) via Act 14 (2020) and HRS Chapter 328G, treating any product above that threshold as marijuana under HRS Chapter 329 ([legalclarity.org](https://legalclarity.org/is-delta-9-legal-in-hawaii-laws-limits-and-penalties/?utm_source=openai)). In December 2024, Hawaii adopted interim rules under HAR Chapter 11‑37 (effective December 6, 2024) that impose total THC limits per serving and per container: edibles (tablets, capsules, powders, softgels, gelcaps) are capped at 1 mg total THC per serving and 5 mg per container; oil‑based tinctures at 2.5 mg per serving and 75 mg per container; beverages at 0.5 mg per container ([cannabisregulations.ai](https://www.cannabisregulations.ai/state-legality/hawaii-delta-9?utm_source=openai)). Act 269 (effective January 2026) requires retailers and distributors of manufactured hemp products to obtain a Certificate of Registration from the Department of Health’s Office of Medical Cannabis Control and Regulation ([legalclarity.org](https://legalclarity.org/is-cbd-legal-in-hawaii-thc-limits-and-state-laws/?utm_source=openai)). HAR Chapter 11‑37 also bans smokable hemp, flower, vape cartridges, foods and beverages containing cannabinoids, and synthetic/isomerized cannabinoids like delta‑8, delta‑10, HHC, THCO, CBN ([health.hawaii.gov](https://health.hawaii.gov/hempprogram/consumers-of-mhp-faq/?utm_source=openai)).

Shipping guidance

Inbound shipments of compliant manufactured hemp products are allowed, provided they meet Hawaii’s form and potency restrictions. Age verification (21+) is required at retail. Retailers must hold a Certificate of Registration to receive and sell hemp products.

All manufactured hemp products must be lab tested by a qualified laboratory. Testing must include cannabinoid content and contaminants per HAR Chapter 11‑37. Certificates of Analysis must be accessible to consumers via QR code or URL on the label. COA retention requirements follow DOH rules.

What to buy

Allowed products include manufactured hemp in the following forms: tablets, capsules, powders, softgels, gelcaps, oil‑based tinctures, beverages, and topicals for skin or hair, provided they meet THC limits and testing requirements.

What to avoid
