Product sources: The ITTO reports that a very important source of timber. The timber is exported regularly, especially as square-edged timber and veneer.

Environment profile: The environmental status of this species within its geographical boundaries has not been officially determined. The geographical range of Cedrela is throughout Latin America, from Mexico to Argentina, except Chile. The trees prefer rich, well-drained humid soils, but may also be found growing on drier hillsides

Tree size: Tree height is 20-30 m

and the sapwoodPinkish, White to yellow.The grain isVariable figure, the textureUniformand the lusterLow

Natural durability: Very high natural resistance, Very suitable for exterior applications

Odor: The wood has a fragrant, cedary scent due to the presence of oil which may exude and appear on the surface of the timber as a sticky resin

Kiln Schedules: Schedule H (4/4) United Kingdom

Drying Defects: Slight collapse and honeycomb, Slight twist/warp

Ease of Drying: Fairly Easy

Comments: Volatiles in the material may restrict the use of the wood in some applications. Timber from younger or fast-grown trees is commonly less resinous

Blunting Effect: Blunting effect on machining is slight

Boring: The wood is difficult to bore cleanly

Carving: Easy to carve

Cutting Resistance: Easy to saw The wood saws without too much difficulty, though there may be a tendency towards woolliness, and resin may clog tools. Cross-cutting and narrow bandsawing operations are satisfactorily

Gluing: Satisfactory gluing properties

Mortising: Good mortising properties

Moulding: A French head yields the most satisfactory moulding

Movement in Service: A French head yields the most satisfactory moulding

Nailing: Holds nails well, Satisfactory nailing properties

Planing: A good finish may be produced in planing if the cutting angle is reduced to 20 degrees

Resistance to Impregnation: Sapwood is permeable

Response to hand tools: Easy to machine

Routing recessing: Good in both routing and recessing.

Steam bending: The wood is suitable for bends of moderate radius of curvature

Turning: Good results

Polishing: Surface treatment advised; Staining: Stains well ;
