Wood has in several ways become a sought after material, much thanks to the materials advantages from a sustainability point of view. There are several indicators that this will continue and that the competition of the raw material will increase. The efficient utilization of raw materials is considered central, both from a societal perspective but also for the individual company, which can increase their profitability with a well considered wood. The complexity of the raw material puts great demand on knowledge and logistics to achieve an efficient utilization. This study is a case study that investigates the requirements of the wood for the production of pine parquet at the parquet producer Berg & Berg. To clarify the consumers need, a literature study about the customer preferences about floor has been carried out. To be able to develop a descriptive model on which timber best meets the requirements, from production as well as the customers’ needs, a literature study about pines wood property has been done. This examines how the wood properties vary within logs, between individual trees and between stands. In addition, a description is made of how the raw material is handled by the forest and sawmill industry with the help of literature studies. The wood properties that are important for the customer when buying flooring is the visual appearance in which an even distribution of knots is the most desirable. Dry knots create problems with rework in the production. The most suitable wood is obtained from stands with a lower site index. It’s the middle part of the trunk that meets the requirements for an even knot structure with a larger green-knot zone with a lower proportion of juvenile wood. A one-sided focus on increased volume and lower production costs in forestry and sawmill industry, as well as information barriers between different players in the production chain, makes it more difficult to efficiently utilize the raw material where a more customer oriented range is received. With good knowledge about wood properties, a simple tree model can be derived. For a producer, the tree model can simplify the communication with wood suppliers to obtain a more customer oriented wood.
