U.S. production volumes are classified as confidential business information.

US productionCBI

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

Import value, 2024$917M

Top sourceCanada 95%

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. 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.

Where It Comes From

Customs basis: HS 290110 · basket

EPA reports by year

2023: US production Confidential · Imports Confidential
2019: US production Confidential · Imports Confidential

These shares come from HS customs code 290110, which covers 58 tracked chemicals in total. They estimate the category's origin mix, not this chemical specifically.
