TT-76 – Electronic smoking device manufacturer licensing (housemade liquids)

License Requirements and Eligibility |

What retailers must know about licensing requirements when producing e-liquids

Maryland law requires retailers who produce their own e-liquids to be licensed as manufacturers, and this guidance explains when that requirement applies and the consequences of operating without a license.

What you need to know

  • Retailers producing e-liquids are considered manufacturers
  • A manufacturer license is required before selling these products
  • Unlicensed sales must stop immediately
  • Violations may result in fines or criminal penalties

Who This Applies To

This guidance applies to:

  • Retailers selling electronic smoking devices (ESDs)
  • Vape shop operators producing e-liquids

When a Manufacturer License Is Required

You must obtain an ESD manufacturer license if:

  • You produce “housemade” e-liquids for sale
  • The product is intended to be vaporized or aerosolized

What Changed

Maryland updated the definition of ESD to include:

  • Vaping liquids
  • Components and substances used in ESD devices

This change means:

  • Producing e-liquids qualifies as manufacturing

Required Action

If you produce e-liquids:

  • You must complete the required license application
  • You must obtain an ESD manufacturer license before continuing sales

Prohibited Activity

You may NOT:

  • Sell housemade e-liquids without a manufacturer license

If unlicensed:

  • You must immediately stop sales

Enforcement and Penalties

Operating without a license may result in:

  • Criminal misdemeanor charges
  • Fines up to $1,000
  • Possible imprisonment
  • Enforcement inspections by state agents

What This Means for Businesses

Retailers should:

  • Evaluate whether they produce e-liquids
  • Apply for a manufacturer license if required
  • Stop sales until properly licensed
  • Prepare for compliance inspections

Important Notes

  • Producing e-liquids changes your regulatory classification
  • Licensing is required before sales can continue
  • Enforcement actions may be immediate
