PLIB’s fundamental objective is to provide impartial inspection of forest products, in a uniform manner, in accordance with contractual specifications between buyer and seller.
Supervision of grading and grade stamping of lumber with its registered logo is the primary function of the Bureau. PLIB also supervises facilities with dry kilns and monitors the marking of heat treated (HT) lumber. These services are provided by the Bureau at its member mills for products that will be shipped to both domestic and foreign destinations. PLIB’s services are also available at cost to any lumber manufacturer, wholesaler, specifier or interested party involved in a lumber transaction. In addition to providing quality control supervisory service, PLIB publishes the Export R List Grading and Dressing Rules, long used in the overseas export trade of Western lumber.
PLIB is approved by the USDA Animal Plant Health Inspection Service (APHIS) and the Canadian Food Inspection Service (CFIA) to issue “Heat Treatment Certification Using a Kiln Facility” documents. These certificates are required to meet import requirements of the European Union (EU) and are also used to obtain phytosanitary certificates from APHIS or CFIA for lumber exports into other countries.
PLIB employs a field staff of experienced quality control supervisors that are highly respected for their knowledge and integrity in the supervision of lumber production, grading and grade marking. The superior performance of the Bureau has been recognized by both the American Lumber Standards Committee (ALSC) and the Canadian Lumber Standards Accreditation Board (CLSAB). Both organizations have accredited PLIB as a provider of competent and reliable lumber inspection, certification and grade marking services.
Since its inception in 1903, the Bureau has functioned as an international organization, with Canadian and United States lumberman working closely together. PLIB’s Board of Directors are selected to provide fair representation across all areas of production and all sizes of mills.
