At least one company claimed its 2019 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. US production volume is confidential. Production reporting year: 2019. Import value and source-country shares describe a shared customs category, not a separate chemical measurement.
