Subpart I_Operations by Dealers and Users of Specially Denatured Spirits
 
Sec.  20.179  Package identification number or serial number.

    (a) Requirement. A dealer who fills packages with specially 
denatured spirits shall mark each package with a package identification 
number, in accordance with paragraph (b) of this section, or a serial 
number, in accordance with paragraph (c) of this section.
    (b) Package identification number. A package identification number 
shall apply to all of the packages filled at the same time on which all 
of the marks required by Sec.  20.178 (a)(1) and (a)(3) through (a)(8) 
are identical. All of the packages in one lot shall be the same type, 
have the same rated capacity, and be uniformly filled with the same 
quantity. A package identification number shall be derived from the date 
on which the package is filled, and shall consist of the following 
elements, in the order shown--
    (1) The last two digits of the calendar year;
    (2) An alphabetical designation from ``A'' through ``L,'' 
representing January through December, in that order;
    (3) The digits corresponding to the day of the month; and
    (4) A letter suffix when more than one identical lot is filled into 
packages during the same day. For successive lots after the first lot, a 
letter suffix shall be added in alphabetical order, with ``A'' 
representing the second lot of the day, ``B'' representing the third lot 
of the day, etc. (e.g., the first three lots filled into packages on 
November 19, 1983, would be identified as ``83K19,'' ``83K19A,'' and 
``83K19B'').
    (c) Serial number. A consecutive serial number shall be marked on 
each package, beginning with the number ``1'' and continuing in regular 
sequence. The dealer shall use a separate but similar number series for 
packages containing specially denatured rum. When any numbering series 
reaches ``1,000,000'', the dealer may recommence the series by providing 
an alphabetical prefix or suffix for each number in the new series.
    (d) Continuation of numbering series. If a change in proprietorship, 
name, or trade name occurs, the numbering system in use at the time of 
the change may be continued. If serial numbers are used at the time of a 
change, the numbering series in use at the time of the change may be 
continued.
