2.4.1.2. Cord. The amount of wood that is contained in a space of 128 cubic feet when the wood is ranked and well stowed. For the purpose of this regulation, “ranked and well stowed” shall be construed to mean that pieces of wood are placed in a line or row, with individual pieces touching and parallel to each other, and stacked in a compact manner.
2.4.1.3. Representation. A “representation” shall be construed to mean any advertisement, offering, invoice, or the like that pertains to the sale of fireplace or stove wood.

2.4.2. Identity. A representation may include a declaration of identity that indicates the species group (Example: 50 percent hickory, 50 percent miscellaneous softwood). Such a representation shall indicate, within 10 percent accuracy, the percentages of each group.
2.4.3. Quantity. Fireplace and stovewood shall be advertised, offered for sale, and sold only by measure, using the term “cord” and fractional parts of a cord or the cubic meter, except that:
(a.) Packaged natural wood. Natural wood offered for sale in packaged form in quantities less than 0.45 m3 (1/8 cord or 16 cu ft) shall display the quantity in terms of cubic meters, to include decimal fractions of cubic meters; or cubic feet, to include fractions of cubic feet.
(b.) Artificial compressed or processed logs. A single fireplace log shall be sold by weight, and packages of such individual logs shall be sold by weight plus count.
(c.) Stove wood pellets or chips. Pellets or chips not greater than 15 cm (6 in) in any dimension shall be sold by weight. This requirement does not apply to flavoring chips. (Amended 1976 and 1991)
(d.) Flavoring chips. Flavoring chips shall be sold by volume. (Added 1998)
2.4.4. Prohibition of Terms. The terms “face cord,” “rack,” “pile,” “truckload,” or terms of similar import shall not be used when advertising, offering for sale, or selling wood for use as fuel.

(a.) the name and address of the vendor;
(b.) the name and address of the purchaser;
(c.) the date delivered;
(d.) the quantity delivered and the quantity upon which the price is based, if this differs from the delivered quantity;
