Commercial Grading

Sawn timber appearance grading

According to NHLA grading rules (2015) Possible grading: FAS, Select, Common 1, Common 2, Common 3 In French Guiana, the local name of this species is "ANANGOSSI". Grading is done according to local rules "Bois guyanais classés". Possible grading: Choice 1, choice 2, choice 3, choice 4

Fire Safety

Conventional French grading Thickness > 14 mm: M3 (moderately inflammable)
Thickness < 14 mm: M4 (easily inflammable)
Euroclass grading D-s2, d0
Default grading for solid wood that meets requirements of European standard NF EN 14081-1 (April 2016): structural graded timber in vertical uses and ceilings with minimal mean density of 0.35 and minimal thickness of 22 mm.
