It shall be unlawful—
(a) For any person to use the words "United States", "Government", or "Federal", or any abbreviation thereof, in, or in connection with, any statement relating to the grade of tobacco when such grade is not, in fact, one of the grades for tobacco according to the standards of the United States.

(c) For any person, not an authorized inspector under this chapter, to issue a certificate or report stating the type, grade, size, or condition of any lot of tobacco to be in accordance with the standards of the United States therefor which is of such color, size, arrangement, or wording as to be mistaken for a certificate issued under this chapter, unless such certificate states in prominent letters in its heading that it is not issued under authority of the United States.
