State the applicable supplier grade description and the appearance characteristics the project needs to review.
Separate appearance from other properties
An appearance description is not a structural grade, a durability claim or a certification. Identify the supplier's stated grade terminology and obtain its written explanation before relying on it. List the visible characteristics that matter to the project, such as color variation, grain variation, permitted surface features and the face intended to remain visible. Avoid adjectives that imply a universal classification when no agreed rule has been identified. If a recognized grading rule is required, name the rule and edition through the responsible specification process.
Set a representative reference
One attractive board may not communicate the range in a shipment. Ask for an appropriately representative sample set and label each piece with its source and finish condition. Record whether the review concerns raw wood, prepared wood or a finished assembly. Lighting, surface preparation and applied finish can influence the visual comparison, so identify those conditions in the review notes. Photographs help preserve context but should not become the sole color reference where physical samples were required. Make any sample limitations visible to the reviewer.
Define the handling of differences
Explain how delivered material will be compared with the agreed reference and who will resolve appearance questions. Do not assume that normal material variation allows any difference, or that a sample guarantees identical boards. Record the specific characteristic being questioned, its location and the associated batch information. If selection or sorting is expected, assign that work and its timing before installation begins. Preserve the disposition with the sample record so a later conversation does not depend on memory. The completed appearance record documents the agreement without creating an unsupported grade or performance guarantee.

General wood science context; chapters on lumber, moisture, fastening and finishing. Not a project specification or product approval.
Original planning guidance. References support their stated technical scope; examples and workflows do not establish product approval.
