Packaging Quality Ninety percent of ArbreCorp’s product is sold on the international market through Boismarche Ltee, a large marketing agency. Boismarche represents all forest products mill owned by ArbreCorp’s parent company as well as several other clients in the region. The market for building-grade lumber is very price competitive, because there are numerous mills selling a relatively undifferentiated product. However, some differentiation does occur in product packaging and presentation. Buyers will look closely at the packaging when deciding whether to buy from ArbreCorp or another mill.
