S.C. Code Ann. § 58-17-2100: Classification of cotton as "heavy goods"; weights.

All cotton packed in bales transported by common carriers within the limits of this State shall be classed as "heavy goods," that is to say an article to be weighed and charged for and treated accordingly. But any common carrier before receiving such cotton for shipment may demand from the shipper the weights of the several bales thereof and may adopt them as the weights upon which freight is to be charged. And in case of loss, no recovery shall be had by any shipper for a greater amount than the weights so furnished by him.
