Rev. Rul. 55-490

The Industrial Alcohol Regulations do not require that the date of filling be placed on packages of specially denatured alcohol although the filling date appears in the illustration of marks in section 182.735. Accordingly, the filling date need not be stenciled or imprinted on packages of specially denatured alcohol. This ruling applies to packages of specially denatured alcohol only. The filling date must be shown on packages of completely denatured alcohol and proprietary solvents
