No label or packaging material bearing official identification may be used unless finished copies or samples of the labels and packaging material have been approved by the Department. No label bearing official identification shall be printed for use until the printer's final proof has been approved by the Department. Final approval may be given to the printer's final proof or photostatic copies of labels for shipping containers or containers for institutional packs, and no labels shall be used until the proofs or copies have been approved by the Department. A label that bears official identification shall not bear any statement that is false or misleading. The diameter of the inspection mark used on labels for inspected products shall be equal to at least one-tenth of the length of the label, plus at least one-tenth of the width of the label. If the labeling is printed or otherwise applied directly to the container, the principal display panel of the container shall, for this purpose, be considered as the label.
