Cannabis Product Liability Insurance

What Does Cannabis Product Liability Insurance Cover?

Product liability pays defense costs and damages when someone claims a cannabis product harmed them, for example through contamination, faulty vape hardware or inadequate warnings. It does not pay to recall or replace product.

In the ISO Commercial General Liability form, product claims fall under the products-completed operations hazard: bodily injury and property damage occurring away from premises the insured owns or rents and arising out of its product or work. That hazard carries its own aggregate limit. Cannabis businesses often place the exposure as a dedicated product liability policy or review it as a separate part of the general liability placement.

Product claims generally rest on three kinds of defect:

• Design defect: the product is unsafe as designed, before anything is made.
• Manufacturing defect: something goes wrong in production, such as contamination.
• Marketing defect: improper instructions or a failure to warn of hidden dangers, which in cannabis often means labeling.

Claims can be brought in negligence, strict liability or breach of warranty. There is no federal products liability law, so the rules come from each state.

The standard CGL form excludes the cost of withdrawing or recalling products. Those costs are addressed by product recall insurance.

Why Is Product Liability Different For Cannabis Businesses?

Cannabis product claims can reach every business that touched the product, contamination and recall events are documented by state regulators, and many policies exclude cannabis. The NAIC calls products liability one of the thorniest insurance issues for cannabis businesses.

Products liability law allows claims against each party in the chain of distribution, from component and product manufacturers to wholesalers and retailers. The NAIC's 2023 regulatory guide notes that product claims may be made against any, and potentially all, entities in the cannabis supply chain: retailer or distributor, manufacturer, tester or cultivator.

Documented events show how the exposure plays out:

• During the 2019 to 2020 EVALI lung injury outbreak, the FDA reported that THC-containing vaping products, particularly from informal sources, were linked to most cases, and that vitamin E acetate was strongly linked to the outbreak.
• Michigan's Cannabis Regulatory Agency has published recall and safety bulletins on vitamin E acetate, lead in vape cartridges and unreliable lab test results, and continued to issue recalls in 2025.
• California's Department of Cannabis Control issued a mandatory recall in January 2022 for flower contaminated with Aspergillus niger mold.

Policy wording matters. ISO's CG 40 14 cannabis exclusion applies to both the CGL and the Products/Completed Operations Liability Coverage Part. Cannabis law firm Harris Sliwoski also warns that an absolute health hazard exclusion can remove coverage for almost any adulterated product that causes bodily injury.

Which Cannabis Businesses Commonly Carry It?

Any business whose name is on the product or in its chain of custody commonly carries product liability: manufacturers, processors, cultivators, brands, distributors and retailers. Massachusetts and Michigan set minimum requirements.

• Manufacturers and processors: extraction, edibles, beverages, vapes and topicals.
• Cultivators: flower and pre-rolls sold under their name or supplied to others.
• Brands and white-label partners: companies whose name appears on the package.
• Distributors and retailers: businesses that sell or move product they did not make.
• Testing labs: named by the NAIC among supply chain entities that may face product claims.

State requirements include:

• Massachusetts: 935 CMR 500.105(10) requires product liability of no less than $1,000,000 per occurrence and $2,000,000 in aggregate, annually, with a deductible no higher than $5,000 per occurrence, or a $250,000 escrow when insurance cannot be obtained.
• Michigan: MCL 333.27408 requires proof of financial responsibility of at least $100,000 per license for bodily injury from adulterated marijuana products, through a policy issued by an insurer or captive licensed in Michigan. The Cannabis Regulatory Agency's September 2023 bulletin states that adult-use licensees may use a constant value bond instead.

Requirements change, so verify current rules with the state cannabis regulator before relying on this page.

How Are Limits Typically Structured?

Product liability is typically written with an each occurrence limit and a products-completed operations aggregate that caps total product claims for the policy period. The NAIC reports that most insurers offer $1 million per occurrence and $2 million aggregate policies in commercial and general liability, which matches the Massachusetts product liability minimum.

The per occurrence limit caps what the policy pays for one incident. The aggregate caps what it pays for all product claims in the policy year, so a contamination problem affecting many buyers can erode it quickly. Deductibles or self-insured retentions apply per claim or per occurrence depending on the policy.

The NAIC's 2023 guide reports that a common complaint in cannabis is constrained limits, for example $1 million per occurrence and $2 million aggregate. Operators with larger product volume commonly look at excess or umbrella layers above the primary policy.

Additional insured status is part of the structure. Michigan's Cannabis Regulatory Agency states that the only additional insureds permitted on the required policy are the municipality, parent company, landlord, managerial employees, approved brand, or a lease or rental equipment company.

What Do Carriers Ask For When Quoting Product Liability?

Underwriters focus on testing compliance, operational maturity, management experience, written standard operating procedures, and any prior recalls or regulatory infractions. Product type and where product is sold also shape the review.

The Connecticut Insurance Department's 2022 report lists twelve product liability rating considerations. Among them:

• Compliance with testing protocols.
• Operational maturity of the business.
• Management experience in the industry.
• Existence and quality of documentation of standard operating protocols.
• Existence of prior product recalls or regulatory infractions.

Because labeling and testing rules differ by state, underwriters also look at which markets a product is sold in.
