Product sources: The timber is abundant in the countries where it grows, but its availablity on the North American market is rather limited because of very high shipping costs. High shipping costs added to the price of the timber make Parana pine too expensive in comparison to domestic softwood species used for similar applications. It is rated in the moderate price range compared to other imports, but the price is substantially higher than North American softwoods of similar grade.Supplies of Parana pine in long lengths, wide boards, and veneer form are also limited on the European market, with prices, when available, comparable to those of the more expensive softwoods.
