International Paper announced plans to convert the No. 16 paper machine at its Riverdale mill in Selma, Alabama, to produce containerboard by the third quarter of 2026. The mill currently supplies Sylvamo with approximately 260,000 short tons of cutsize uncoated freesheet annually from the machine through a supply agreement.

"The Riverdale supply agreement is not part of our long-term strategy. We have been planning for this conversion since our 2021 spinoff, including making strategic investments in our footprint in North America. We will support our customers throughout this transition," said Jean-Michel Ribiéras, chairman and chief executive officer, Sylvamo.
