FDA Denatured Guideline for hand sanitizer

The FDA released the following statements on March 27th, 2020 Production of Hand Sanitizer to Address the COVID-19 Pandemic

Tax-free ethanol may be used to produce hand sanitizer if it is denatured according to TTB regulations and Food and Drug Administration (FDA) guidance.

Alcohol, whether or not denatured, may be delivered tax-free to state and local governments for non-beverage purposes. The same is true for hospitals, blood banks, sanitariums, certain pathological laboratories, non-profit clinics, and qualifying educational institutions, if not for resale or use in the manufacture of any product for sale.

 (TTB) has found it desirable to waive provisions of internal revenue law with regard to distilled spirits, and therefore is providing certain exemptions and authorizations to distilled spirits permittees who wish to produce ethanol-based hand sanitizers to address the demand for such products during this emergency.  Any existing DSP therefore can immediately commence production of hand sanitizer or distilled spirits (ethanol) for use in hand sanitizer without having to first obtain authorization.

TTB is authorizing the manufacture of hand sanitizer products by DSPs using a formulation in the FDA guidance cited above without first obtaining formula approval from TTB.

Industrial alcohol user permittees may also use denatured ethanol to manufacture hand sanitizer using a formulation in the FDA guidance without first obtaining formula approval from TTB.  During the period covered by this guidance, TTB is also exempting industrial alcohol user permittees from the requirement to request approval from TTB to increase the quantities of denatured ethanol that they may procure.
