What is the term for standing timber or cut roundwood that is suitable for converting to pulp for making paper or cellulose based products?

The term for standing timber or cut roundwood that is suitable for converting to pulp for making paper or cellulose-based products is pulpwood. This classification is specifically designated for wood that is primarily harvested to produce pulp, which is then processed into paper, cardboard, or other cellulose-based materials. Pulpwood typically consists of smaller diameter trees or lower-quality logs that may not be suitable for lumber production but are ideal for making pulp due to their fiber content.

In contrast, firewood refers to wood that is cut and used for fuel, typically for heating; saw timber encompasses higher quality and larger diameter trees that can be processed into lumber for construction; and fuelwood is a broader term that generally refers to any wood used as fuel, which can include both firewood and wood waste. Therefore, pulpwood is the precise term used to describe timber intended for pulp production, making it the correct choice.
