ISI Mark for H Acid , K Acid & Vinyl Sulphone

Per India's Quality Control Orders (QCOs), the BIS certifications for H Acid (IS 8637:2020), K Acid (IS 11557:1986), and Vinyl Sulphone (IS 18340:2023) are required as effective from May 14, 2025.  Compliance with BIS criteria is required of manufacturers and importers to guarantee product safety and quality.  Applications, product testing, manufacturing inspections, and compliance verification comprise the certification process.  Once a successful review yields a license from BIS, the Standard Mark may be used.  Domestic sales require this certification; exports are not covered.  Legal fines in line with the BIS Act, 2016 could follow non-compliance.
