The Director shall from time to time weigh or measure and inspect packages or amounts of commodities held, offered or exposed for sale or sold or in the process of delivery, to determine whether they contain the amounts represented and are being held, offered or exposed for sale or were sold in accordance with law. When such packages or amounts of commodities are thus determined not to contain the amounts represented or are found to be kept, offered or exposed for sale in violation of law, the Director may restrain such offer, exposure or sale by order and may so mark or identify them to indicate the illegality thereof. In carrying out the provisions of this Section, the Director may employ recognized sampling procedures under which the compliance of a given lot of packages will be determined on the basis of the result obtained on a sample selected from and representative of such lot. No person shall (1) sell, or keep, offer or expose for sale in intrastate commerce any package or amount of commodity that has been ordered off sale or marked or identified as provided in this Section unless and until such package or amount of commodity fully complies with all legal requirements, or (2) dispose of any package or amount of commodity that has been ordered off sale or marked or identified as provided in this Section and that does not comply with legal requirements in any manner except with the specific approval of the Director
