Lumber Grading & Inspection Services

PLIB offers lumber grade stamping, certification, quality control inspections, and grader training and certification to sawmills and lumber remanufacturing facilities throughout the Pacific Northwest and Western Canada.

PLIB is accredited by both the American Lumber Standard Committee (ALSC) and the Canadian Lumber Standards Accreditation Board (CLSAB). These authorities recognize PLIB as an approved inspection agency for all established sets of grade rules used in the western U.S. and Canada:

  • NLGA rules
  • RIS rules
  • WCLIB rules
  • WWPA rules

This accreditation includes all grades and species of lumber covered by these rules as well as glued and machine graded lumber (MSR and MEL) and heat treated (HT) lumber (link to the MSR/MEL & FJ page).

In addition to North American domestic grade rules, PLIB has a long history of supporting overseas export lumber trade by writing export grade rules and providing supervisory services for other international grades and standards including:

  • Export R-List Grading & Dressing Rules (published by PLIB)
  • CE Marking (European Union)
  • AQIS Certification (Australia)
  • British Standard 4978 (UK)
  • CFLA JPS 1 (formerly known as the Japan E 120 rule)
  • HT certification (required by many foreign countries)

PLIB membership and grading services are available to all primary or secondary manufacturers of softwood lumber. Member mills must agree to and abide by the PLIB subscriber contract and licensing agreement. Costs include an initial deposit and a monthly fee based on production volume.

Grading services
Members receive grade stamp services through PLIB’s Grade Stamp License Agreement program. This program authorizes qualified mill personnel to apply the PLIB registered grade mark and issue Certificates of Inspection. The PLIB registered grade mark and inspection certificates are recognized worldwide as evidence of quality.

At the foundation of the PLIB grade service program are the PLIB Supervisors, whose decades of combined mill experience make them highly respected throughout the industry. Our inspectors possess deep knowledge about lumber manufacturing as well as processing, grading, scanning technology, lumber drying, and quality control. Armed with this knowledge and experience, PLIB Supervisors make regular mill visits to check grading accuracy and verify lumber quality as well as to instruct, train, and certify mill graders.

In addition to grading services related to ALSC and CLSAB approved rules and standards, PLIB provides quality control compliance services as they relate to any standards, rules, and regulations established by manufacturers, buyers, sellers, government agencies, code authorities, or any other parties to transactions involving graded softwood lumber.

What to expect
PLIB Grading Service Subscribers receive:

  • Authorization for qualified personnel to grade stamp lumber and issue grade  certificates.
  • Regular inspections by knowledgeable, experienced PLIB Supervisors.
  • Grade Quality Reports after every inspection.
    Reports address items related to grade quality, size, moisture content, species, and general observations. These reports provide critical data to mill quality control supervisors for use in evaluating and improving grade quality and recovery.
  • Grader instruction, training, and certification.
    Canadian mills receive formal classes covering all aspects of the NLGA grade rule book. Graders who successfully complete the evaluation become certified and receive a PLIB grading ticket. For U.S. mills, PLIB’s grader certification program involves on-site instruction of mill personnel and intensified quality checks.
  • Technical support services and representation by PLIB on industry standards writing committees and regulatory agency committees.
  • Timely communications on current industry issues.
  • Opportunities to explore and expand international export sales through PLIB’s membership in the Softwood Export Council (SEC).
