Introduction

The Ministry of Commerce and Industry, via the Department for Promotion of Industry and Internal Trade (DPIIT), has mandated BIS certification for Portland Slag Cement under IS 455: 1989. Effective January 1, 2024, all manufacturers of Portland Slag Cement must obtain BIS certification to meet national quality standards. Compliance with BIS certification, indicated by the ISI mark, ensures that PSC meets the necessary criteria for durability and safety, supporting consistent quality in the construction sector.

Why is BIS Certification Necessary for Portland Slag Cement?

BIS certification for Portland Slag Cement under IS 455: 1989 enforces stringent quality and performance standards, reducing risks associated with low-quality cement, which can compromise structural integrity. The Cement (Quality Control) Order, 2023, legally requires manufacturers to comply, with penalties for non-compliance under the Bureau of Indian Standards Act, 2016. Certification assures end-users of the quality, reliability, and long-term safety of the product, thereby supporting the infrastructure and construction industries.
