Hawaii hemp laws: quick overview

Hawaii defines hemp and manufactured hemp products under Hawaii Administrative Rules Chapter 11‑37 (interim rules effective December 6 2024, updated January 28 2026) implementing HRS Chapter 328G (Act 269, SLH 2025) ([health.hawaii.gov](https://health.hawaii.gov/medicalcannabis/statutes-and-rules/?utm_source=openai)). The state limits total THC (sum of Δ9‑THC and THCA × 0.877) to no more than 0.3% by weight in any crude extract or manufactured hemp product ([health.hawaii.gov](https://health.hawaii.gov/medicalcannabis/statutes-and-rules/?utm_source=openai)). Specific per‑serving and per‑container THC limits are codified in HAR §11‑37‑5: gummies/tablets/capsules/powders/softgels/gelcaps limited to 1 mg THC per serving and 5 mg per container; oil‑based tinctures (from March 1 2025) max 2 oz container, 2.5 mg per serving, 75 mg per container; beverages 6–12 fl oz, max 0.5 mg per container ([law.cornell.edu](https://www.law.cornell.edu/regulations/hawaii/Haw-Code-R-SS-11-37-5?utm_source=openai)). The rules also prohibit sale of hemp flower, seeds, leaf material, vape cartridges, concentrates, foods or beverages containing cannabinoids outside defined MHP forms, and any products containing synthetic or artificially derived cannabinoids such as delta‑8, delta‑10, HHC, etc. ([health.hawaii.gov](https://health.hawaii.gov/hempprogram/consumers-of-mhp-faq/?utm_source=openai)).

Shipping guidance

Raw hemp biomass (flower, leaf, live plants, viable seeds) requires a transportation report to HDOA at least three business days before movement; processed hemp products are exempt ([hdoa.hawaii.gov](https://hdoa.hawaii.gov/hemp/?utm_source=openai)). Inbound shipments of manufactured hemp products are allowed but retailers/distributors must hold a valid Certificate of Registration (effective Jan 1 2026) ([health.hawaii.gov](https://health.hawaii.gov/hempprogram/?utm_source=openai)). Age verification (21+) is required for oil‑based tinctures; other products require child‑resistant packaging and warning labels but not age checks unless specified ([health.hawaii.gov](https://health.hawaii.gov/hempprogram/consumers-of-mhp-faq/?utm_source=openai)).

Testing & COA guidance

All manufactured hemp products must undergo batch testing for cannabinoid content (including total THC) and contaminants (solvents, pesticides, heavy metals, microbials, mycotoxins) ([health.hawaii.gov](https://health.hawaii.gov/hempprogram/consumers-of-mhp-faq/?utm_source=openai)). Testing labs must meet state requirements (ISO 17025 not explicitly stated; unknown) and each package must include a batch number and QR code or web link to COA ([health.hawaii.gov](https://health.hawaii.gov/hempprogram/consumers-of-mhp-faq/?utm_source=openai)). COA retention duration not specified in sources (null).

What to buy

Allowed products are manufactured hemp products in forms: gummies, tablets, capsules, powders (sealed packets from March 1 2025), softgels, gelcaps, oil‑based tinctures (with dropper/spray), topicals, and beverages (6–12 fl oz) ([health.hawaii.gov](https://health.hawaii.gov/hempprogram/consumers-of-mhp-faq/?utm_source=openai)).

What to avoid

Prohibited: hemp flower, leaf, viable seeds, pre‑rolls; vape cartridges, concentrates; foods or beverages containing cannabinoids outside defined MHP; synthetic or artificially derived cannabinoids (delta‑8, delta‑10, HHC, etc.) ([health.hawaii.gov](https://health.hawaii.gov/hempprogram/consumers-of-mhp-faq/?utm_source=openai)).
