Sodium oxide

Drug ingredient

CAS 1313-59-3

This drug ingredient has classified U.S. production volumes. EPA withholds the number as confidential business information.

US productionCBI
Import value, 2024$123M
Top sourceBrazil 32%

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.
