Ethanol (Ethyl Alcohol)

Ethanol has applications in industry, pharma manufacturing, research and academia as a reagent as well as a solvent. Because of its relatively low toxicity compared with other alcohols and ability to dissolve non-polar substances, ethanol can be used as a solvent in medical drugs, perfumes, and vegetable essences such as vanilla. In organic synthesis, ethanol serves as versatile intermediate.

Ethyl alcohol, Pure (Tax-Free)

First-Time Applicants for Tax-Free Ethanol
Customers wishing to order any of Sigma-Aldrich′s Tax-Free ethanol products are required to apply and obtain a valid Federal Industrial Alcohol User permit from the Alcohol and Tobacco Tax and Trade Bureau (TTB).

The application process can be submitted by standard U.S. mail or via the TTB Permits Online process. We highly recommend new applicants review a Permits Online Tutorial for Tax-Free ethanol before applying. Customers that plan to follow the status of their permit application must submit and track digitally through Permits Online. Application tracking is not available for applications sent by standard mail.

Sample permit application documents are available below to help guide applicants through the permit process:

TTB F 5150.22: Application for an Industrial Alcohol User Permit
TTB F 5150.22 Example

TTB F 5100.1: Signing Authority for Corporate and LLC Officials
TTB F 5100.1 Example

Once you have obtained a valid Federal Industrial Alcohol User permit, Sigma-Aldrich has Tax-Free ethanol options for you! When ordering any of our Tax-Free 140, 160, 190 or 200 proof ethanol products, please include your permit number on each Purchase Order and make sure the ship-to address exactly matches what is listed on your permit.

Reagent Alcohol (Tax-Free)

Reagent Alcohol (RGA) is a widely used denatured ethanol. Since it is denatured (5 parts by gallon of IPA to 95 parts SDA 3A), it is also not subject to Federal Tax in the U.S.. However a letter of registration or "Letterhead Approval" from the TTB must be on file for quantities greater than 4L and provided to Sigma-Aldrich prior to purchase.

Specially Denatured Alcohol (Tax-Free)

We offer a wide range of Specially Denatured Alcohol (SDA) 190 & 200 proof ethanols. These products are not subject to Federal Tax in the U.S., as they are Pure Ethanols denatured with co-solvents in order to render them "unfit to drink". As with the Pure Ethanol, SDA requires a valid Industrial Alcohol User permit be provided to Sigma-Aldrich prior to purchase.

Ethanol (Tax-Paid)

Purchasing 190- and 200-proof ethanol has never been easy, until now! Because these ethanols are federally regulated, a TTB permit is required to purchase 190- and 200-proof ethanol. Sigma-Aldrich takes the hassle out of this process for you. No TTB paperwork is needed, nor any records for you to keep. Sigma-Aldrich immediately pays the federal excise tax (200-proof pure alcohol=$27.00/gallon).

We offer tax-paid ethanol in a variety of grades to meet your application and available in amber glass bottles and Sure/Seal bottles.
