According to Law360 on September 8, 2026, Mesa Underwriters Specialty Insurance Company, or MUSIC, has asked the U.S. District Court for the Western District of Washington to declare that it has no duty to defend or indemnify vape distributor i5 Distribution Inc. in a product liability lawsuit involving an Elf Bar BC5000 disposable vape.
The insurance dispute stems from a serious underlying product liability case in which consumer William Kelley Courser Jr. alleges that an Elf Bar BC5000 distributed by i5 caught fire and exploded in his pants pocket, causing severe burns and ultimately requiring an above-the-knee amputation of his left leg.
Consumer Alleges Elf Bar BC5000 Exploded in His Pocket
Courser sued i5 Distribution and Satguru Ji Corporation in Washington state Superior Court in September 2025.
According to his allegations, the Elf Bar BC5000 spontaneously caught fire and exploded in his pants pocket in November 2022.
Courser says he suffered severe burns to his legs, torso and parts of his arms and that his left leg later had to be amputated above the knee.
He alleges that the product was defectively manufactured, designed and produced and that it lacked adequate instructions or warnings.
Those claims remain allegations in the underlying product liability case and have not been established by a final court ruling.
MUSIC Seeks Declaration That It Owes No Coverage
MUSIC issued i5 Distribution a commercial general liability policy covering the period from June 1, 2022, through June 1, 2023, which includes the date of the alleged incident.
The insurer is currently providing a defense to i5 under a reservation of rights.
At the same time, MUSIC has filed a separate federal declaratory judgment action seeking a ruling that it has no continuing duty to defend or indemnify i5 and owes no payment toward any judgment Courser may obtain in the underlying lawsuit.
The federal case is docketed as 3:26-cv-06008.
Policy Contains Tobacco and Nicotine Product Exclusion
One of MUSIC’s principal arguments centers on a tobacco, nicotine or nicotine replacement products endorsement in i5’s policy.
According to the federal complaint, the endorsement excludes bodily injury, property damage and personal or advertising injury arising out of the use, exposure to, existence or presence of, or contact with, tobacco, nicotine or nicotine replacement products.
The provision specifically lists a vaporizer as an example of a covered category.
MUSIC argues that Courser’s alleged injuries arose from a disposable nicotine vapor product and therefore fall within the exclusion.
The federal court has not yet ruled on that interpretation.
Premises Limitation Provides Second Coverage Argument
MUSIC is also relying on a premises limitation endorsement.
According to the insurer, the policy only covers bodily injury or property damage if the alleged occurrence takes place at a listed insured premises.
MUSIC says the explosion alleged by Courser did not occur at the premises identified in i5’s policy.
That gives the insurer a second, separate basis for arguing that the claim falls outside coverage even if the court reaches a different conclusion on the nicotine product exclusion.
Similar Exclusions Have Appeared in Other Vape Insurance Cases
MUSIC has previously relied on similar policy language in litigation involving vape-related injuries.
In August 2026, an Oregon federal court entered a default judgment in Mesa Underwriters Specialty Insurance Company v. Midway Vishions.
That dispute also involved an injury allegedly caused by a vape product. MUSIC relied on nicotine and vaporizer exclusions as well as a premises limitation to argue that the claim was outside the scope of coverage.
The court ultimately found that MUSIC had no duty to defend or indemnify in that case.
The Oregon ruling was a default judgment, however, and the facts, procedural posture and policy language are not identical to those in the i5 case, meaning it does not automatically determine the outcome in Washington.
Elf Bar BC5000 Has Separate FDA Enforcement History
Elf Bar BC5000 also has a separate U.S. regulatory history.
The U.S. Food and Drug Administration has previously issued warning letters involving the sale of unauthorized Elf Bar products and specifically identified Elf Bar BC5000 in enforcement documents.
The FDA said those products lacked the marketing authorization required for legal sale in the United States.
That regulatory issue is separate from the product liability and insurance disputes. There is currently no evidence establishing that the product’s FDA authorization status caused the explosion alleged by Courser.
Product Liability Risk Extends Into Insurance Coverage
The broader industry significance of the case is that product liability exposure may not always be fully transferred through a standard commercial general liability policy.
Where policies contain explicit exclusions for tobacco, nicotine, vapor products or incidents occurring outside listed premises, claims arising directly from a company’s core vape business may still fall outside insurance coverage.
For vape distributors and retailers, the case highlights that insurance risk depends not only on whether a business carries commercial liability coverage, but also on how the policy defines nicotine products, product liability and covered premises.
The i5 dispute remains at an early stage, and the federal court has not yet determined whether MUSIC is entitled to avoid defense or indemnity obligations.
Law360 reported that counsel for i5 Distribution and Courser had not immediately responded to requests for comment as of September 8, while a representative for MUSIC also did not immediately comment.
