Wisconsin’s New Hemp Vape Registry: Is hemp going to be Illegal in Wisconsin?

Wisconsin has introduced new requirements for hemp-derived electronic vaping devices, changing which products may legally be sold throughout the state.

As of July 2, 2026, hemp-derived vaping devices must be listed in the Wisconsin Department of Revenue’s Electronic Vaping Device Directory before they can legally be sold or offered for sale in Wisconsin.

These changes may affect the products available at vape shops, hemp retailers, dispensaries and convenience stores across the state. Some businesses may need to remove products from their shelves, while others may decide to discontinue vaping products entirely.

For consumers, the new law creates an important question:

Is the product you are purchasing registered for legal sale in Wisconsin?

What Is the Electronic Vaping Device Directory?

The Electronic Vaping Device Directory is a public database maintained by the Wisconsin Department of Revenue.

The directory identifies electronic vaping devices that manufacturers have certified under Wisconsin law. Consumers and retailers can search the directory using information such as:

• Manufacturer name

• Brand name

• Product name

• Product description

• Universal Product Code, or UPC
  

The directory covers more than traditional nicotine vapes. Wisconsin’s definition of an electronic vaping device can also include hemp-derived disposable devices, vape pens, cartridges, components and substances intended to be vaporized or inhaled.

The directory gives retailers and consumers a way to verify whether a specific vaping product has gone through the state’s required certification process.

What Changed for Hemp-Derived Vaping Products?

Wisconsin previously allowed additional time for manufacturers of hemp-derived vaping products to meet the state’s directory requirements. That temporary extension has now ended.

Manufacturers of qualifying hemp electronic vaping devices were required to submit their product certifications by July 1, 2026.

Beginning July 2, 2026, hemp vaping devices that are not listed in the directory can no longer legally be sold or offered for sale in Wisconsin.

Unlisted products may also be subject to seizure or destruction.

Additional enforcement provisions begin on September 1, 2026. At that point, manufacturers and retailers that continue selling unlisted devices may face significant financial penalties.

These requirements mean that products previously sold throughout Wisconsin may no longer be legally available unless the manufacturer completed the registration process.

Is Wisconsin Banning Hemp Vapes?

No. The new law does not create a complete ban on hemp-derived electronic vaping devices. Instead, Wisconsin has created a registration and certification system.

Hemp-derived vaping products may continue to be sold when the applicable device has been properly certified and appears in the state directory.

Products that are not listed may no longer be legally sold.

This distinction is important because customers may hear that certain stores are removing products or closing their doors and assume that all hemp vaping products have been banned.

The reality is that product availability will depend largely on whether manufacturers and retailers have taken the necessary steps to comply with the new law.

What Must Manufacturers Do?

Manufacturers cannot simply submit a company name and have every product automatically approved.

The certification process generally applies to individual devices and product variations. Different flavors, concentrations or product types may require separate submissions.

Manufacturers must provide product information to the Wisconsin Department of Revenue and pay the applicable certification fees.

For hemp-derived vaping devices, manufacturers must also submit documentation such as an independent Certificate of Analysis.

The laboratory testing is used to demonstrate that the product:

• Contains hemp as defined under Wisconsin law

• Does not contain nicotine

• Meets the applicable delta-9 THC concentration requirements

• Matches the specific product being submitted for certification

Manufacturers must also renew or recertify qualifying devices annually to keep them listed. This creates an ongoing responsibility for manufacturers rather than a one-time registration.

What Does the Registry Mean for Product Safety?

The new registry provides additional product identification, documentation and accountability.

Requiring manufacturers to submit product information and laboratory documentation can help regulators, retailers and consumers better understand what products are being offered in the state.

However, consumers should also understand what directory placement does—and does not—mean.

A product appearing in the directory means the manufacturer completed the applicable certification process under Wisconsin’s electronic vaping-device law.

It does not necessarily mean that the State of Wisconsin has independently tested, approved or endorsed every aspect of the product.

Consumers should still purchase from reputable businesses, review available product information and follow all product warnings and instructions.

What Does This Mean for Wisconsin Retailers?

Retailers are now responsible for making sure the hemp vaping devices they offer appear in the state directory.

A retailer should not assume that a product is compliant simply because it was previously available, came from a familiar distributor or is sold by another business.

The exact product should be checked.

This is especially important because separate flavors, formulations and device variations may have different directory listings.

Retailers carrying unlisted devices may need to:

• Remove the products from their sales floor

• Stop offering them online

• Return them to the manufacturer or distributor

• Dispose of them according to applicable requirements

• Replace them with properly listed products

Businesses that have not prepared for the changes could experience inventory shortages or interruptions in their ability to sell vaping products.

What Should Consumers Look For?

Customers purchasing hemp-derived vaping devices in Wisconsin should ask whether the specific product is listed in the Electronic Vaping Device Directory.

Consumers can also search the public directory themselves here: Wisconsin DOR Electronic Vaping Device Directory

When checking a product, look for the exact:

• Brand

• Product name

• Flavor

• Concentration

• Device description

• UPC

Checking only the manufacturer or general brand name may not be enough. One product from a brand could be registered while another flavor or variation is not. Customers should be cautious when a retailer cannot confirm whether a product appears in the directory.

Why Might Some Businesses Stop Selling Hemp Vapes?

The new certification system creates additional expenses and administrative responsibilities for manufacturers.

Each product variation may require separate documentation, testing, fees and annual recertification.

Some manufacturers may decide that registering every product is not financially practical.

Smaller brands may reduce the number of products they offer in Wisconsin or withdraw from the state entirely.

Retailers that rely heavily on unregistered brands may also experience challenges. In some cases, stores may need to dramatically reduce inventory or stop selling electronic vaping devices.

This does not necessarily mean every business affected by the law was operating illegally before the changes.

It means Wisconsin has created a new standard that manufacturers and retailers must now meet to continue operating in the electronic vaping-device market.

Why Legal Compliance Matters

The hemp-derived product industry has changed rapidly over the past several years.

Businesses have had to adapt to new testing requirements, packaging standards, age restrictions, product definitions and state-specific regulations.

The electronic vaping-device directory is another major step in Wisconsin’s evolving regulatory system.

Businesses that intend to remain in the industry must be willing to:

• Follow changes in state law

• Maintain accurate product records

• Work with qualified laboratories

• Confirm that products meet current requirements

• Remove products that are no longer eligible for sale

• Communicate regulatory changes honestly to customers

For consumers, choosing a business that takes these responsibilities seriously can provide greater confidence and transparency.

THE Dispensary Is Prepared for the New Requirements

THE Dispensary has completed the required manufacturer certification process for its applicable hemp-derived vaping devices, and its approved products have been added to Wisconsin’s Electronic Vaping Device Directory.

This allows THE Dispensary to continue offering registered hemp vaping products as the new law takes effect and enforcement increases.

While certain products or businesses may disappear from the Wisconsin market, compliant retailers and manufacturers can continue operating; THE Dispensary remains open and committed to providing legally available hemp-derived products while adapting to Wisconsin’s changing regulations.

Customers can continue shopping with confidence, knowing that compliance, transparency and responsible operations remain a priority.

A Changing Industry Requires Informed Consumers

Wisconsin’s new electronic vaping-device requirements will likely change which hemp products customers see on store shelves.

The law may initially create confusion, especially as businesses remove unlisted products and customers hear conflicting information about what is and is not legal.

The most important facts are straightforward:

Hemp-derived vaping devices have not been completely banned in Wisconsin.

However, qualifying devices must now appear in the Wisconsin Department of Revenue’s Electronic Vaping Device Directory to be legally sold.

Consumers should verify products, ask questions and choose retailers that are prepared to meet the state’s evolving requirements.
