Paper Manufacturing
NAICS 322: Paper manufacturing — U.S. containerboard, tissue, and pulp production, Smurfit WestRock, and industry consolidation.
Industry at a Glance
Sector-wide aggregates across all businesses classified under NAICS 322 (2017 classification frame). For specific sub-industries within this sector, see the individual reports below.
Industry Overview
Paper Manufacturing (NAICS 322) covers the production of pulp, paper, and paperboard from wood fiber, recycled fiber, and other cellulose sources. The sector includes mills producing containerboard and corrugated packaging, tissue and hygiene products, printing and writing papers, and specialty grades for food service, filtration, and industrial applications.
International Paper and WestRock (merged with Smurfit Kappa in 2024 to form Smurfit WestRock) lead the containerboard and corrugated segment, while Georgia-Pacific (Koch Industries), Packaging Corporation of America, and Graphic Packaging round out the top producers. In tissue and hygiene, Procter & Gamble, Kimberly-Clark, and Georgia-Pacific dominate consumer brands. Production concentrates in the U.S. Southeast — Georgia, Alabama, Mississippi — where proximity to managed pine forests provides cost-effective fiber supply, along with Wisconsin and the Pacific Northwest for specialty and recycled grades.
The sector operates under EPA Clean Air Act and Clean Water Act regulations governing mill emissions and effluent discharge. The Sustainable Forestry Initiative and Forest Stewardship Council certification programs increasingly shape fiber procurement practices. E-commerce growth has been the structural tailwind for containerboard, while printing and writing paper volumes have declined steadily as digital communications displace physical media.

Industry Trends
The 2024 Smurfit Kappa-WestRock merger created a global containerboard and packaging leader, continuing a decade of consolidation that has reduced the number of independent U.S. corrugated producers.
Mills are converting printing and writing paper machines to containerboard and packaging grades, with International Paper and Graphic Packaging both executing major machine conversions to match shifting demand.
SFI and FSC chain-of-custody certification is becoming a procurement prerequisite for major consumer brands, pushing mills to document fiber sourcing from certified managed forests.
EPA Boiler MACT rule compliance and state-level air quality permits are driving capital investment in recovery boiler upgrades and biomass energy systems at integrated kraft mills.
Recycled fiber recovery rates continue rising, with over 65% of U.S. corrugated boxes recovered for recycling, though contamination from mixed-stream collection poses ongoing quality challenges for recycled containerboard.
