Sodium bisulfite
Drug ingredientThis 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$30M
Top SourceItaly 45%
The EPA did not publish how much of this chemical companies made or imported, or marked that amount confidential. Without that volume, ACID cannot calculate import dependency.
