The system for review and development of TAPPI Standards requires an announcement of review dates so that any interested TAPPI parties may access the drafts, submit comments, and/or join the Standard-Specific Interest Group (SSIG) to cast an official vote.

Listed below are the Standards that will be up for review in 2025. The date indicated is the target date on which the draft will be distributed to the Standard-Specific Interest Group (SSIG) for that particular Standard.
