Cordia trichotoma es una especie de alto valor maderero indicada como de posible restación comercial en el norte del Cono Sur sudamericano. Suponiendo su cultivo en plantaciones de alta cantidad de individuos por hectárea, se estudió su densidad de madera, composición química y celular, para un eventual uso de los raleos como materia prima papelera. Se ncontró que el duramen es demasiado denso para ello y su albura aunque densa podría utilizarse como tal. Posee más celulosa y extractivos que la madera de los Eucalyptus papeleros de la región, en detrimento del contenido de hemicelulosas. En cuanto a la proporción de tejidos celulares tiene más fibras, similar contenido de elementos vasculares y mucho menos parénquima. Estos resultados confirman la posible utilización de los raleos que no hayan formado duramen.
