Is it true or false that lumber leaving a sawmill must be graded by trained inspectors?

The statement is true. Lumber leaving a sawmill must be graded by trained inspectors to ensure that it meets specific quality and safety standards. Grading involves assessing the lumber for characteristics such as strength, appearance, and defects. This process helps to ensure that the lumber is suitable for its intended use, whether it be for construction, furniture-making, or other applications. Proper grading not only aids in maintaining industry standards but also provides consumers with confidence in the quality of the products they are purchasing.

Options that suggest falsehood or conditions based on region or wood species do not hold because regardless of these factors, established grading standards are in place to ensure that all lumber, irrespective of variety or location, is consistently evaluated for quality.
