Pennsylvania's effort to control which vaping products can be sold within its borders is facing another legal challenge, and recent federal appeals court decisions could make the road ahead more difficult for the retailers fighting the law.
A federal judge has asked the businesses challenging Pennsylvania's product directory to explain why two recent rulings involving similar state laws should not lead to the rejection of their case. The dispute centers on Act 57 of 2025, a Pennsylvania law that establishes a directory of nicotine-containing electronic cigarettes eligible for sale in the state.
Supporters view the registry as a way to bring greater oversight to the vape market, while opponents argue that it gives state officials too much authority over a process already governed by federal regulators.
At the heart of the disagreement is a question with implications beyond Pennsylvania: Can a state restrict the sale of vaping products through its own registry without improperly stepping into the federal government's role in regulating tobacco products?
What Pennsylvania's Product Directory Requires...
Under Act 57, manufacturers must meet specific requirements for their products to qualify for inclusion in Pennsylvania's directory. Generally, products must have authorization from the U.S. Food and Drug Administration or satisfy limited conditions associated with a timely submitted premarket tobacco product application, commonly known as a PMTA.
The directory identifies qualifying manufacturers and products, including product categories and flavors. Retailers and wholesalers are given a limited period to remove products that do not appear on the list. Once that period expires, unlisted products can be treated as contraband and may be subject to seizure or destruction. The law does not technically prohibit specific flavors across the board.
However, its practical impact could still be significant. Because relatively few vaping products have received FDA marketing authorization, particularly outside tobacco and menthol categories, the registry could substantially narrow the selection available to Pennsylvania consumers.
State officials have also emphasized that businesses must follow Pennsylvania's licensing and distribution requirements. Guidance from the Department of Revenue states that retailers must obtain tobacco products through licensed wholesalers, with products purchased outside the required system potentially subject to seizure.
Why Retailers Are Challenging the Law
The lawsuit, MMA Group 1 Inc. v. Sunday, was filed on May 20, 2026, in the U.S. District Court for the Middle District of Pennsylvania. The plaintiffs include businesses operating dozens of Tobacco Hut stores, 101 Distributors LLC, and related companies. They are challenging Attorney General Dave Sunday and Revenue Secretary Patrick Browne, with U.S. District Judge Julia K. Munley overseeing the case.
The retailers argue that Pennsylvania's directory effectively requires businesses to enforce federal premarket application requirements.
Their concern is that the FDA controls the federal authorization process and applies its enforcement policies selectively, while the state registry could prevent products from being sold regardless of how federal regulators have approached individual products. Pennsylvania takes a different position.
State officials argue that the law regulates sales within Pennsylvania rather than attempting to enforce federal tobacco law directly. In their view, the fact that state requirements overlap with federal product standards does not automatically make the directory unconstitutional.
This distinction matters because federal preemption can limit a state's ability to regulate an area where Congress has established controlling federal rules. The lawsuit asks whether Pennsylvania has crossed that line or is exercising authority it retains over products sold within its borders.
Two Appeals Court Decisions Complicate the Case
The legal outlook changed on July 30, 2026, when two federal appeals courts issued decisions involving similar product registry laws. The Fourth Circuit upheld North Carolina's registry in a 2–1 decision. The majority concluded that the state was regulating which products could be sold within its borders rather than directly enforcing the federal Food, Drug, and Cosmetic Act.
Pennsylvania was among 28 states that supported North Carolina's position. On the same day, the Eighth Circuit reversed an injunction that had blocked Iowa's registry. That court found that the challengers were unlikely to succeed in demonstrating that federal law preempted the state's requirements.
These decisions create a substantial obstacle for Pennsylvania's challengers because their arguments relied partly on the earlier injunction against Iowa's law. With that injunction reversed and the North Carolina law upheld, the retailers must now explain why their Pennsylvania case should proceed differently.
The rulings do not automatically decide the Pennsylvania lawsuit. However, they provide legal reasoning that Pennsylvania can use to defend its own registry and may influence how Judge Munley evaluates the competing arguments.
What Happens Next?
Judge Munley previously converted the plaintiffs' request for a preliminary injunction into a motion for summary judgment, shifting the immediate focus toward whether the dispute can be resolved based on the legal arguments and record before the court.
Both sides submitted additional briefs following the July 30 appeals decisions. The retailers were asked to address why those rulings should not undermine their challenge, while state officials continue to argue that the registry falls within Pennsylvania's authority.
The central issue remains whether the directory is a permissible state sales regulation or an impermissible attempt to impose federal product-authorization requirements through state law. The answer could influence how Pennsylvania's registry operates and how similar laws are challenged elsewhere.
Why the Case Matters for Pennsylvania's Vape Market
The outcome could affect manufacturers, distributors, retailers, and consumers. If the law survives, businesses may need to review their inventories and supply chains carefully to ensure that the products they sell appear in the state directory and come through approved distribution channels.
Manufacturers could also face greater pressure to secure the documentation and authorizations needed to qualify for state registries. For retailers, a narrower list of eligible products could mean changes to purchasing decisions and the selection available in stores. For now, the recent appeals decisions have strengthened Pennsylvania's legal position, but they have not ended the dispute.
The case remains an important test of how far states can go when regulating vaping products alongside an existing federal framework. Its eventual resolution could help clarify the balance between state sales restrictions and federal oversight of the nicotine market.
