Hindustan Zinc, the world’s largest and India’s only integrated producer of zinc, lead and silver, has reinforced its global credibility by securing a comprehensive range of international and national certifications. These include REACH compliance for the European Union, certification from the Bureau of Indian Standards (BIS), and the globally recognised London Bullion Market Association (LBMA) Good Delivery accreditation for silver, along with several other internationally benchmarked standards. Collectively, these recognitions underscore the company’s focus on delivering high-purity, safe and consistent metal products that meet stringent global quality requirements.

Supported by advanced digital quality systems, modern smelting technologies and robust end-to-end process controls, Hindustan Zinc offers a diversified and globally trusted product portfolio. This includes Special High Grade (SHG) zinc, High Grade (HG) zinc, Continuous Galvanising Grade (CGG) zinc, zinc base-alloy ingots and billets for die-casting applications (Grade Zn Al 4), as well as LBMA-certified 99.99 per cent pure silver bars in one kg and 30 kg formats, and silver powder. These products cater to key sectors such as automotive, infrastructure, renewable energy, electronics, construction and consumer durables. The certifications validate product purity and consistency while reflecting alignment with global regulatory frameworks, advanced metallurgical practices and customer-focused quality assurance systems.

Commenting on the milestone, Arun Misra, CEO and Whole-Time Director, Hindustan Zinc, said that quality is embedded as a core value across the organisation’s operations, people and processes. He added that the certifications reflect the company’s zero-defect mindset and continued focus on innovation, modernisation and raising global benchmarks in quality, safety, sustainability and responsible mining.

Beyond product quality, Hindustan Zinc has also positioned itself as a leader in sustainable and low-carbon metal production. Its low-carbon zinc offering, EcoZen, produced using renewable energy and validated through a life-cycle assessment, has a carbon footprint of less than one tonne of CO? equivalent per tonne of zinc—nearly 75 per cent lower than the global average. The product enables customers to reduce Scope 3 emissions while supporting more resilient and sustainable supply chains.

This integrated approach to quality, process excellence, innovation and sustainability has also contributed to Hindustan Zinc becoming the first Indian company to be inducted into the International Council on Mining and Metals (ICMM). Membership of ICMM is reserved for mining companies that demonstrate strong compliance with international sustainability benchmarks, ethical governance standards and leadership in environmental and social responsibility.

With operations spanning more than 40 countries, Hindustan Zinc continues to advance responsible mining and metals production through an expanding portfolio of global certifications, technology-led quality management systems and a sustained focus on long-term value creation.
