29.1111—Rule 5.

Daily before weighing any tobacco for the purposes of the Act, a weigher shall verify the accuracy of the scales to be used by him. Except as may be otherwise specified by the Director, all weights certificated shall be within an accuracy of 1 pound.
All standard grades must be clean unless otherwise noted by a special factor.
The grade assigned to any lot of tobacco shall be a true representation of the tobacco at the time of inspection and certification. If, at any time, it is found that a lot of tobacco does not comply with the specifications of the grade previously assigned, it shall not thereafter be represented as such grade.
A lot of tobacco on the marginal line between two colors shall be placed in the color with which it best corresponds with respect to body or other associated elements of quality.
Any lot of tobacco which meets the specifications of two grades shall be placed in the higher grade. Any lot of tobacco on the marginal line between two grades shall be placed in the lower grade.
A lot of tobacco meets the specifications of a grade when it is not lower in any degree of any element of quality than the minimum specifications of such grade.
The use of any grade may be restricted by the Director during any marketing season when it is found that the grade is not needed or appears in insufficient volume to justify its use.
Any special factor approved by the Director of the Tobacco Division, Agricultural Marketing Service, may be used to show a peculiar side or characteristic of the tobacco which tends to modify the grade.

Code of Federal Regulations

[42 FR 21092, Apr. 25, 1977, as amended at 49 FR 16756, Apr. 20, 1984]
Interpretations, the use of specifications, and the meaning of terms shall be in accordance with determinations or clarifications made by the Chief of the Marketing Programs Branch and approved by the Director.
In determining the grade of a lot of tobacco, the lot as a whole shall be considered. Minor irregularities which do not affect over one percent of the tobacco shall be overlooked.
Degrees of uniformity shall be expressed in terms of percentages. The percentages shall govern the portion of a lot which must meet the specifications of the grade. (These percentages shall not affect limitations established by other rules.) The minor portion must be closely related, but may be of a different group, quality, and color from the major portion.
