(a) Each plant must submit and have approved a code to appear legibly on the cover of each container. This code will show the plant where packed, year packed, the product contained therein, day code, and period code. The period shall be changed every two and one half hours or less. This time interval may be extended to three hours if a petition is filed with the Department demonstrating that adequate consumer protection is provided under those conditions when potentially hazardous products are required to be removed from retail market. If a container such as a glass bottle be used and the cap or cover be too small to permit the coding to be embossed or ink-stamped thereon, it shall be permissible to legibly perforate or ink-stamp the required code on the label, provided the label is securely affixed to the container.Cal.
