Resistance to Dry Wood Borers: Class D – durable (sapwood demarcated, risk limited to sapwood)
Resistance to Termites: Class S – susceptible
Treatability: Class 3 – poorly treatable
Use Class Covered by Natural Durability: Class 3 – not in ground contact, outside JACAREÚBA
Durability Notes: Poorly to moderately resistant to termites. According to the European standard NF EN 335 of May 2013, performance length might be modified by conditions in which it is used.

Log Buoyancy: Does not float
Log Conservation: Moderate (treatment recommended)

Sawing Machining Notes: Some difficulties with sawing and machining due to interlocked grain. Resin can sometimes clog tools.
Assembly Notes: Tends to split with nailing.
Additional Notes: Filling is recommended to obtain a better finish. Some uses mentioned call for a, slight interlocked grain
