Hawaii's hemp landscape is undergoing significant transformation as the state implements some of the nation's most restrictive Hawaii hemp interim rules 2025, targeting delta-8 and similar intoxicating cannabinoids with unprecedented precision. The Department of Health's interim rules, effective December 6, 2024, and carrying forward into 2025, establish stringent THC limits, mandatory testing protocols, and child-resistant packaging requirements that fundamentally reshape how hemp products can be manufactured and sold in the Aloha State.
Understanding Hawaii's New Hemp Product Framework
The updated interim rules represent a dramatic shift from Hawaii's previously more permissive hemp environment. Under Chapter 11-37 of Hawaii Administrative Rules, the state now permits only select oral formats with severely restricted THC content, marking one of the most conservative approaches to hemp regulation in the United States.
Allowable Product Types and THC Limits
Starting March 1, 2025, Hawaii restricts edible manufactured hemp products to six specific categories:
- Tablets (1 mg total THC per serving, 5 mg per package)
- Capsules (1 mg total THC per serving, 5 mg per package)
- Powders (1 mg total THC per serving, sealed in individual packets, 5 mg per package)
- Softgels (1 mg total THC per serving, 5 mg per package)
- Gelcaps (1 mg total THC per serving, 5 mg per package)
- Oil-based tinctures (maximum 75 mg total THC per container, 2-fluid-ounce volume limit)
- Topical products (no THC serving limits, but must remain ≤0.3% total THC)
- Beverages (0.5 mg total THC per container, 6-12 fluid ounce volume range)
Notably absent from this list are gummies, edibles in food form, and smokeable hemp products—all of which remain explicitly prohibited under Hawaii law.
The Delta-8 Crackdown Continues
Hawaii's ongoing battle against delta-8, delta-10, and synthetic cannabinoids intensifies in 2025. Under HRS §328G-3, the state maintains its ban on artificially derived and synthetic cannabinoids in manufactured hemp products, particularly food products. This prohibition specifically targets:
- Delta-8 THC products
- Delta-10 THC products
- Any synthetic cannabinoids
- Artificially derived cannabinoids
- Products intended for inhalation (vape pens, nebulizers, inhalers)
Mandatory Testing and Certificate of Analysis Requirements
All compliant hemp products must undergo comprehensive laboratory testing covering:
Required Testing Parameters
- Cannabinoid content analysis (including total THC, CBD, and other cannabinoids)
- Contaminant screening (pesticides, heavy metals, microbials, residual solvents)
- Potency verification to ensure THC limits are maintained
- Moisture content and water activity for applicable products
Manufacturers must maintain Certificates of Analysis (COA) for all products and make these readily available to consumers and regulators. The DOH strongly encourages retailers to work directly with processors, distributors, and suppliers to ensure all finished products comply with testing requirements found in subchapters 2 and 3 of HAR Chapter 11-37.
Child-Resistant Packaging and Labeling Requirements
Packaging Standards
All edible manufactured hemp products sold in multi-serving packages must meet Title 16 C.F.R. part 1700 child-resistant packaging requirements. This includes:
- Child-resistant closures for the number of openings customary for package size
- Compliance with federal special packaging standards
- Tamper-evident sealing where applicable
Mandatory Labeling Elements
Every compliant hemp product must display:
- Total THC content in milligrams per container
- Amounts of other cannabinoids (CBD, CBG, etc.) present
- Serving size information clearly marked
- Age restriction warnings (21+ for tinctures)
- Advisory statements regarding psychoactive effects
- Ingredient lists with hemp and non-hemp components identified
- Manufacturer/processor contact information
- COA accessibility information
The 2026 Registration Requirement: HB 1482
Governor Josh Green signed HB 1482 into law on July 2, 2025, establishing a comprehensive registration system for hemp product distributors and retailers. Beginning January 1, 2026, this legislation creates new compliance obligations:
Who Must Register
- All manufactured hemp product distributors operating in Hawaii
- All manufactured hemp product retailers selling hemp products
- Both in-state and out-of-state entities shipping products to Hawaii consumers
Registration Exemptions
The following entities are exempt from registration requirements:
- Hemp processors with valid Chapter 328G permits
- Retailers selling only CBD topicals
- Distributors of tinctures containing ≤0.3% THC (though age restrictions apply)
Enforcement Authority
Under the new law, the Department of Health gains significant enforcement powers:
- Inspection authority for sales and distribution facilities
- Product confiscation and seizure powers for non-compliant items
- Administrative fines up to $10,000 per violation
- Registration revocation for repeated violations
Before and After Compliance Strategy
Businesses operating in Hawaii's hemp market must implement comprehensive compliance overhauls to align with the new regulatory framework.
Current Non-Compliant Products to Phase Out:
- Gummies and food-based edibles
- Products exceeding 1 mg THC per serving
- Multi-serving packages exceeding 5 mg total THC
- Delta-8, delta-10, or synthetic cannabinoid products
- Vape products and smokeable hemp
- Tinctures exceeding 75 mg THC or 2-fluid-ounce volumes
Compliant Product Transition:
- Reformulate existing products to meet serving size limits
- Transition gummy products to compliant tablet or capsule formats
- Ensure all tinctures meet volume and potency restrictions
- Source only naturally derived cannabinoids from hemp
- Implement individual powder packet sealing
Testing and Documentation Upgrades
Enhanced Quality Control:
- Partner with Hawaii-approved testing laboratories
- Implement batch-by-batch testing protocols
- Establish COA management and distribution systems
- Create consumer-accessible COA platforms
- Document supply chain compliance from cultivation to retail
Facility and Operations Modifications
Physical Compliance Changes:
- Install child-resistant packaging equipment
- Update labeling systems for mandatory warning statements
- Create age verification systems for tincture sales (21+)
- Establish secure storage for compliant inventory
- Implement waste disposal protocols for non-compliant products
Registration Preparation (Before January 1, 2026)
Documentation Requirements:
- Compile business registration materials

- Prepare inspection readiness protocols
Enforcement Reality and Penalties
Hawaii's enforcement approach combines immediate penalties with progressive compliance support. Retailers found selling non-compliant hemp products face fines up to $10,000 per offense, including mandatory product removal from sale.
The state's enforcement priorities focus on:
- High-THC products exceeding serving size limits
- Synthetic cannabinoid products (delta-8, delta-10)
- Unlabeled or mislabeled products lacking required warnings
- Age-restricted sales violations (tinctures to under-21 consumers)
- Unregistered retailers operating after January 1, 2026
Consumer Protection and Market Impact
Hawaii's restrictive approach prioritizes consumer safety over market accessibility. The 1 mg THC serving limit represents one of the lowest thresholds in any US hemp market, effectively limiting psychoactive effects while maintaining legal compliance with federal hemp definitions.
Market Consolidation Effects
The stringent requirements are expected to:
- Reduce the total number of available hemp products
- Increase product costs due to compliance investments
- Favor established manufacturers with testing and packaging capabilities
- Eliminate smaller operators unable to meet regulatory costs
- Create barriers to entry for new market participants
Consumer Education Imperatives
Retailers must actively educate consumers about:
