In Ohio, the most common, legal method of sale for firewood is the cord or fraction of a cord. A "cord" is defined as 128 cubic feet when the wood is stacked and well stowed. The seller must provide the purchaser with a delivery ticket with:
Identity of the product in descriptive terms
Name and address of the vendor and purchaser
Quantity upon which the price is based
Total price of the delivery
When selling, advertising, or offering firewood for sale, a "cord" is the acceptable measure to use.
