Sodium nitrite
Drug ingredientCAS 7632-00-0
This drug ingredient has classified U.S. production volumes. EPA withholds the number 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$13M
Top sourceIndia 64%
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.
