Kiln-dried and air-dried timber describe different approaches to reducing moisture in wood before use. For commercial buyers, the important point is not the label alone but the agreed moisture requirement, intended application and consistency of the supplied material.
When requesting a quotation, buyers should state whether kiln drying is required, any moisture target they need the supplier to work toward, the timber species, dimensions, grade and end use. Requirements should be confirmed in the formal quotation rather than assumed from a broad product name.
Where moisture condition is important to manufacturing, packaging or downstream processing, it should be treated as a defined commercial specification and checked alongside the rest of the order details.
