Sorry, I'm a bit confused. Paragraph A seems to indicate an increasing series number across all packages filled. Paragraph B states that an additional identifier must be present on cases containing bottles, but clearly requires that these identifiers be distinct from those in paragraph A. The way I read it, you must mark each case with two serial numbers, which must be distinct from each other. How can we have distinction if there is only one series?
Additionally, I am wondering about the wording of all the paragraphs. What we are required to do begins with 'must', but many of these sentences include 'may', such as " except that any series of such numbers already in use may be continued to that limit ", which indicates that continuing the series, rather than starting over at 1, is optional?
Has any TTB officer given their specific interpretation of this section of the CFR?
