EPA publishes updated TSCA Inventory (latest non-confidential Inventory update available)

EPA posted an updated biannual public (non-confidential) TSCA Chemical Substance Inventory update. While not a rule change, the Inventory refresh affects substance status screening (existing vs. new chemicals), and may change operational compliance signals via updated commercial activity data (active/inactive), unique identifier data, and regulatory flags (e.g., SNUR/test order indicators). Compliance teams should refresh internal substance lists, re-run regulatory flag screening, and note any identities moved from confidential to public portions of the Inventory as part of EPA’s ongoing CBI reviews.
