S.C. Code Ann. § 46-25-570: Wet or bad mechanical condition.

No commercial fertilizer shall be offered for sale which contains such an amount of water as to render the handling or manipulation of such commercial fertilizer difficult, or to cause the clogging of fertilizer distributors by reason of its bad mechanical condition; such wet or bad mechanical condition of any commercial fertilizer shall be carefully observed by all fertilizer inspectors at the time of drawing their samples, and be reported to the commission or its duly authorized representative, who, if it confirms the opinion of the inspector, shall forbid the sale of that lot so inspected.
