(c) In the case of any material which has been adulterated subsequent to packaging, labeling or loading and before delivery to the consumer, a plainly marked notice to that effect shall be affixed by the vendor to the package or delivery slip to identify the kind and degree of such adulteration.(d) At every site from which agricultural liming materials are delivered in bulk and at every place where consumer orders for bulk deliveries are placed, there shall be conspicuously posted a copy of the statement required by this section for each product.(e) At any time after July 1, 1970, when the Department finds, after public hearing following due notice, that the requirements for expressing the guaranteed analysis of calcium and magnesium in elemental form would not impose an economic hardship on distributors and users of liming materials by reason of conflicting labeling requirements among the States, the Department may require by regulation thereafter that the "guaranteed analysis" shall contain the minimum percentages of calcium (Ca) and magnesium (Mg) in elemental form and calcium carbonate equivalent.3 Del.
