As in any transaction, your safest bet is to deal with a reputable business.
Packaged firewood is required by Minnesota Statute to be clearly marked with the following information.
(Minnesota Statute 239.093)
Minnesota Statute requires firewood sold in bulk to be accompanied by a delivery ticket when the buyer and seller are not both present to witness the measurement. The delivery ticket must contain the following information.
(Minnesota Statute 239.092)
Prior to delivery make sure you get the sellers name, business information and phone number. Without this information, it is difficult to settle a dispute should one arise. If the seller refuses to provide this information, consider doing business with a different company.
Request a receipt with the information above, as well as the price, amount, and agreed upon type of wood. If the seller refuses to give a delivery receipt at the time of delivery, record the delivery vehicle's license plate number.
Try to be present at the time of delivery. Have the delivery person stack the wood, so that you both can determine the correct amount of wood is delivered. If the delivery person cannot wait, or you cannot be there at the time of delivery, and you discover that the delivery is short when it is stacked, do not use any of the wood. Contact the seller immediately. If you cannot settle the matter satisfactorily, contact the Weights and Measures Division.
Firewood may be measured by the cubic foot, the cubic meter, or the cord. If measured by the foot or meter, the wood is first stacked with all pieces placed parallel to each other. The wood is then said to be ranked. Wood must be ranked if it is to be measured accurately. Ranking minimizes the space between the sticks, or pieces, of wood. Some sellers use various cross-stacking methods to exaggerate the quantity of wood delivered. Do not attempt to measure cross-stacked wood.
A cord has a specific legal definition in Minnesota:
No. You and the seller may enter into any agreement you choose, but be aware that words like truckload, face cord, rick, fireplace cord, or pile, have no legal definition. The Weights and Measures Division cannot help you in a dispute if the wood is not sold by the cubic foot, the cubic meter, or the cord.
If the wood is ranked, multiply the wood pile's height by its length and stick (piece) length (height x length x stick length) and divide by 110 if the wood is sawed, by 120 if the wood is sawed and split, and 128 in all other cases. Remember to make all your measurements in feet.
If the wood is loosely thrown into the back of a truck, measure the dimensions of the truck bed and the height of the wood in feet. Multiply the height of the wood by the length and width of the truck bed. Divide by 160 if the wood is sawed, or by 175 if the wood is sawed and split.
