Confidential Business Information. The EPA withholds this volume because publishing it could reveal the reporting company's trade secrets.

Top sourceGermany 67%

At least one company claimed its 2023 production or import volume for this chemical as confidential, so EPA withholds it.

Why supply is unknown

Production is reported production, not a complete census of factories. Production reporting year: 2023. Import value and source-country shares describe a shared customs category, not a separate chemical measurement.
