BIS ISI Mark Certification for Tin Ingot – IS 26:2024 | A Complete Guide
Tin Ingots are widely used in the production of solders, chemicals, coatings, tin plating, and many electrical and electronic applications. As tin is a critical material in multiple industries, its purity and quality must be ensured through strict regulation.
To maintain product safety and uniformity across the Indian market, the Bureau of Indian Standards (BIS) has made it mandatory to obtain ISI Mark Certification for Tin Ingots under the Indian Standard IS 26:2024.
In this blog, we’ll explain everything you need to know about BIS certification for tin ingots, including the certification process, standard requirements, documents, and how to apply.

Why is BIS Certification Required for Tin Ingots?

This mark ensures the product meets all national quality requirements.
