Amended Rule/Section: Manufacturing specifications for Special Denatured Spirit (SDS) and Ordinary Denatured Spirit (ODS)
Type of Change: Circular / Technical Specification
What Changed: This circular issued by the Commissioner of State Excise specifies or revises the proportions of denaturant (विप्रकृतक) that must be used in the manufacture of Special Denatured Spirit (SDS) and Ordinary Denatured Spirit (ODS) from Rectified Spirit. Denatured spirits are alcohol products made unfit for human consumption by adding denaturants, allowing their use for industrial/commercial purposes under different regulatory controls than potable alcohol. This circular likely updates the chemical formulation requirements to ensure proper denaturing and facilitate detection of illicit diversion.
