Exclusion (TSCA PBT)

An exclusion exempts a specific use from PBT manufacturing, processing, or distribution prohibitions. Some are permanent (circuit boards for PIP 3:1), others are time-limited phase-ins. The 2024 revision revised and clarified exclusions, narrowing some and creating new ones.

40 CFR §§ 751.405(b), 751.407(b); EPA Final Rule (November 2024).

Key PIP (3:1) exclusions: circuit boards/wire harnesses (permanent), aerospace lubricants (15-year), motor vehicle new parts (15-year), motor vehicle replacement parts (30-year), manufacturing equipment (10-year). The 2024 revision aligned import prohibitions where domestic use was already banned.

An aerospace company uses PIP (3:1) in turbine lubricants. The 15-year phase-in allows continued use while alternatives are developed.
