NCASI’s extensive research program is funded primarily by annual dues from its Member Companies. Membership is open to forest products companies in the United States, Canada, and beyond North America.
NCASI currently has approximately 80 U.S. Member Companies which represent more than 90% of the paper and paperboard produced, nearly 70% of the wood panels produced, and more than half of industrial timberland acreage in the United States. In 2002, NCASI opened an office for Canadian operations in Montreal, and now has 30 Canadian Member Companies.
Sustaining Member Companies, which currently number 26, are consulting firms, engineering firms, and analytical testing laboratories that provide environmental services to NCASI Member Companies.
