1. Knots: Knots are areas where branches have grown out of the tree trunk, causing a circular pattern in the wood. They can weaken the wood and affect its appearance.
2. Cracks and Splits: Cracks and splits can occur in timber due to drying out or improper handling. These defects can weaken the wood and affect its structural integrity.
3. Warping: Warping is the distortion of the wood's shape, often caused by uneven drying or changes in humidity. This defect can affect the wood's appearance and usability.
4. Decay: Decay is the breakdown of wood caused by fungi or insects. It can weaken the wood and affect its structural integrity.
5. Bark Pockets: Bark pockets are areas where bark has become embedded in the wood during growth. These pockets can weaken the wood and affect its appearance.
6. Stains and Discoloration: Stains and discoloration can occur in timber due to fungal growth, water damage, or chemical exposure. These defects can affect the wood's appearance and may indicate underlying issues with the wood's quality.
7. Insect Damage: Insect damage can weaken the wood and affect its structural integrity. Common wood-boring insects include termites, beetles, and carpenter ants.
8. Shakes: Shakes are separations in the wood fibers that can occur during growth or drying. These defects can weaken the wood and affect its structural integrity.
9. Wane: Wane is the presence of bark or live edge on the surface of the wood. This defect can weaken the wood and affect its appearance.
10. Compression Wood: Compression wood is a type of wood that forms on the underside of branches or leaning trees. It is denser and weaker than normal wood, making it prone to splitting and warping.

Natural Defects
- Knots: Embedded branches that can reduce strength and stability.
- Checks: Splits or cracks that run parallel to the grain.
- Shakes: Separations between the growth layers.
- Warps: Deviations from a flat or straight surface, such as bows, cups, or twists.
- Wane: Bark or edges that protrude from the sides of the timber.
- Pith: The central core of the tree, which can be soft and weak.
- Grain deviation: Abnormal patterns in the grain that can affect strength and durability.
Manufacturing Defects
- Sawing defects: Errors in sawing that result in uneven surfaces, torn fibers, or splinters.
- Planing defects: Irregularities in the surface caused by improper planing.
- Drying defects: Shrinkage, distortion, or cracking due to improper drying processes.
- Treatment defects: Faulty application of preservatives or treatments, which can compromise durability.
- Insect or fungal damage: Holes, tunnels, or discolorations caused by insects or fungi.
Environmental Defects
- Moisture content: Excessive moisture can cause swelling, rot, or decay.
- Temperature: Extreme temperatures can cause cracking or warping.
- UV exposure: Prolonged exposure to sunlight can damage the surface and degrade the wood.
Other Defects
- Heartwood decay: Rot or deterioration of the central core of the tree.
- Sapwood decay: Rot or deterioration of the outer layers of the tree.
- Pockets: Hidden internal voids or cavities.
- Inclusions: Foreign objects, such as stones or nails, embedded in the timber.
- Splinters: Small, sharp fragments of wood that can be a hazard.
