Confidential Business Information. The EPA withholds this volume because publishing it could reveal the reporting company's trade secrets.
Import value, 2024$26M
Top sourceSouth Korea 54%
At least one company claimed its 2023 production or import volume for this chemical as confidential, so EPA withholds it.
Why supply is unknownProduction is reported production, not a complete census of factories. US production volume is confidential. Production reporting year: 2023. Import value and source-country shares describe a shared customs category, not a separate chemical measurement.
