This chemical is listed as active in US commerce, but no company reported it to EPA’s survey for 2019 or 2023. Sites may have made or imported less than the threshold amount, or none.

Why supply is unknown

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

Where It Comes From

Customs basis: HS 293369 · basket

These shares come from HS customs code 293369, which covers 192 tracked chemicals in total. They estimate the category's origin mix, not this chemical specifically.
