The North Carolina Court of Appeals recently issued a decision strengthening the “sealed container” defense available to non‑manufacturing sellers in products liability cases. In Weaver v. AMV Holdings LLC, the court found in favor of a vape retailer and distributor after a lithium‑ion battery malfunctioned in a customer’s pocket, causing serious burns. For retailers and distributors — particularly those dealing with lithium‑ion batteries — this decision underscores the continued viability of sealed container defenses.
The plaintiff, a flooring contractor, used a vaping device powered by removable lithium‑ion cylindrical cells. He purchased the batteries from MadVapes retail stores owned and operated by AMV Holdings LLC and MVRB2, LLC. The batteries were sold in plain white boxes; he contended he received no warnings that they could catch fire or explode. While at a job site, the plaintiff experienced a “thermal runaway event” whereby one of the batteries in his pocket ignited and caused significant burns to his leg and hand. Expert testimony established that the event was caused by a latent, internal manufacturing defect that could not be detected through visual inspection and would require advanced testing to identify.
The plaintiff filed suit against the retailer MadVapes and later joined as a defendant Medusa Distribution, LLC (Medusa), the distributor that supplied the batteries to MadVapes.
The plaintiff asserted a broad array of claims against the defendants, including negligence and gross negligence, failure to warn under North Carolina’s Products Liability Act, and breach of implied warranties of merchantability and fitness for a particular purpose.
A trial court ruled in favor of the defendants by finding that the defect was latent and internal, and the defendants had no reasonable opportunity to discover the defect through inspection. The plaintiff appealed.
On appeal, the court confirmed that the plaintiff’s claims fell within the scope of North Carolina’s Products Liability Act. The statute shields non‑manufacturing sellers and distributors from liability if they acquire and sell the product in a sealed container, or acquire and sell the product under circumstances that afford no reasonable opportunity to inspect in a way that, using reasonable care, would reveal the alleged defect. Because the defect was internal and detectable only through CT scanning and expert analysis, the court concluded that there was no reasonable expectation that the defendants would perform such testing.
Notably, the defense does not apply if the product manufacturer is not subject to North Carolina jurisdiction or has been judicially declared insolvent. The court found that the exception to the defense operates as a statutory carve‑out, and the burden rests on the plaintiff to prove it. Evidence that a Chinese distributor was involved and that the batteries were shipped from overseas was not enough for the plaintiff. The plaintiff did not establish the manufacturer’s identity or its forum contacts with sufficient specificity to show that North Carolina courts lacked jurisdiction. As a result, the court found that the exception did not apply, and the sealed container defense remained available.
The court also rejected several additional theories advanced by the plaintiff:
- “Reputable manufacturer” argument: Older case law referencing “reputable manufacturers” did not create a separate requirement to defeat the sealed container defense, particularly where the manufacturer here was effectively unknown, not affirmatively disreputable.
- More than a “mere conduit”: MadVapes employees recommended the vape device, showed the plaintiff how to use it, and inserted the battery. The court held this basic sales assistance did not transform MadVapes into a manufacturer or assembler akin to cases involving complex installation work.
- Knowledge of general risks/failure to warn: Evidence that MadVapes knew lithium‑ion batteries can be dangerous did not defeat the defense where the specific defect was latent and undetectable by reasonable inspection.
- Counterfeit/misrepresentation theory: The plaintiff’s allegations that the battery was not truly a Samsung cell did not overcome the defense absent a clear causal link between the alleged misbranding and the defect that caused the injury.
Why It Matters
Sealed container defenses provide important protection for retailers, distributors, and other non-manufacturing sellers in product liability litigation by recognizing their limited ability to inspect sealed products. Several other states offer similar statutory defenses (e.g., Delaware, Idaho, Kentucky, Maryland, and Wisconsin). And over half the states offer innocent seller defenses that operate in a similar manner. Thus, any business that sells products with components like batteries intended for use in vaping devices should be aware of these laws and defenses.
