West Coast Lumber Inspection Bureau provides grader training and inspection services for softwood lumber of all U.S. and many foreign species and commercial species groups for both visual and mechanically graded lumber, including the following:

Wood Pellet Certification Program
The Pellet Fuels Institutes (PFI) implemented on November 8, 2011, the PFI Standards Program by the U.S. Environmental Protection Agency (EPA). The New Source Performance Standard (NSPS) for residential wood heaters requires pellet stoves to burn pellets which are certified by the PFI. It also calls for a third-party compliance program with specifications for residential and commercial grade fuel. Manufacturers of PFI graded pellet fuels will be required to place labels on their packaging and the labels be graded as Premium, Standard, or Utility.

The West Coast Lumber Inspection Bureau is an accredited third-party audit agency approved by the American Lumber Standard Committee (ALSC) to certify inidividual manufacturers for the wood pellet program to insure quality standards and demonstrate compliance for wood burning materials.
