The expansion of the Prevent All Cigarette Trafficking (PACT) Act to include electronic nicotine delivery systems (ENDS) transformed the regulatory landscape for vaping products in the United States. What was once a statute focused on cigarettes now applies broadly to vapes, e-liquids, and even components, pulling online sellers, distributors, and manufacturers into a complex compliance framework. Businesses operating in this space must now navigate a combination of federal registration requirements, state tax obligations, and strict shipping rules. The challenge is not simply understanding the law, but operationalizing compliance across multiple jurisdictions with different enforcement priorities.
The first step in the compliance map is identifying who is covered. The PACT Act applies to any person who sells, transfers, or ships ENDS products in interstate commerce. ATF guidance has interpreted this to include those who advertise interstate sales, though the statutory text at 15 U.S.C. § 375 is focused on sellers, transferors, and shippers. This broad framework means that most participants in the vaping supply chain, including online retailers and wholesalers, are subject to the law. The law applies regardless of where the business is located, focusing instead on where products are shipped and sold.
Registration is the foundation of PACT Act compliance, and it is one of the most common areas where businesses fall short. The law requires sellers to register with the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) and with the tobacco tax administrator of each destination state into which they ship products. Importantly, PACT Act registration is a distinct obligation from state-level vape-specific licensing or permits, which many states have layered on top of the federal framework and which carry their own separate requirements. This creates a multi-jurisdictional compliance burden that can quickly become complex, especially for businesses operating nationwide. Federal guidance emphasizes that registration must occur before engaging in interstate sales, making it a prerequisite rather than a formality.1
Once registered, businesses must comply with ongoing monthly reporting requirements, which are often underestimated in practice. The PACT Act mandates that sellers file reports with each state detailing all shipments made during the prior month, including customer information and product quantities. These reports are intended to give states visibility into interstate sales and ensure proper tax collection. Even businesses with limited sales activity are subject to these requirements, making reporting a continuous compliance obligation rather than a one-time task.
Tax compliance is another central pillar of the PACT Act framework. Delivery sellers must comply with all applicable state and local excise tax laws, effectively treating each shipment as if it occurred within the destination jurisdiction. This requires businesses to track varying tax rates, product classifications, and filing deadlines across multiple states. Federal authorities have made clear that failure to comply with state tax obligations is a direct violation of the PACT Act, increasing the stakes for businesses that do not maintain accurate tax systems.
Shipping restrictions represent one of the most significant operational changes under the amended law. The PACT Act, as applied to ENDS, prohibits the use of the United States Postal Service (USPS) to deliver vaping products to consumers, with only very limited exceptions that do not apply to standard commercial distribution. Federal postal guidance confirms that most vaping products are considered nonmailable under the USPS Final Rule effective March 27, 2021. Critically, finding a compliant private carrier is not straightforward—both FedEx and UPS have publicly announced policies declining to ship vaping products, significantly narrowing the available options for businesses and requiring careful vetting of any carrier relationship.
Age verification requirements further complicate compliance by imposing obligations at both the point of sale and the point of delivery. Sellers must verify the age of customers before completing a transaction, and carriers must confirm that an adult is present to receive the shipment. These dual requirements are designed to prevent underage access to vaping products, but they require coordination between businesses and logistics providers. Failure to implement proper verification procedures remains a frequent enforcement issue.
Despite the clarity of the statutory framework, several recurring compliance failures continue to surface. One of the most common mistakes is incomplete registration, particularly in states with evolving vape tax laws or additional licensing requirements. Businesses also frequently struggle with reporting, either failing to file monthly reports or submitting inaccurate data. Tax compliance presents another challenge, as companies often underestimate the complexity of calculating and remitting excise taxes across multiple jurisdictions.
Shipping practices are another major source of risk. Some businesses attempt to use prohibited mailing methods or rely on carriers that do not fully comply with federal requirements, exposing themselves to enforcement action. Others fail to properly label shipments or ensure that age verification occurs at delivery. Federal authorities have emphasized that these types of violations undermine the purpose of the PACT Act and will be subject to enforcement.
The consequences of noncompliance can be severe. The ATF has authority to inspect businesses engaged in delivery sales and enforce both civil and criminal penalties for violations. In addition, noncompliant businesses may face operational disruptions, including the inability to ship products through compliant carriers. These enforcement tools make PACT Act compliance a threshold requirement for participating in the vaping market.
Ultimately, the PACT Act creates a clear but demanding compliance map built on three core obligations: register in every jurisdiction where products are shipped, report all interstate sales accurately and consistently, and ensure that shipping practices meet federal requirements. Businesses that fail to integrate these obligations into their operations often encounter enforcement issues not because the rules are unclear, but because they are not consistently followed. As federal and state authorities continue to coordinate enforcement efforts, companies that do not take a proactive approach to compliance risk being excluded from the market altogether.
