As of April 20, 2020, all TTB laboratories are temporarily closed, pending further notice. Due to these closures, they will not be able to process product samples or paper submissions sent to the laboratories via mail until they reopen.

However, TTB continues to process formulas that do NOT require laboratory sample analysis. Processing times to obtain formula approvals for wine, distilled spirits, and malt beverage products can be found here (; at the time of this posting, the average processing time was 4-5 calendar days.
