Primary Lead is a crucial metal used across a variety of industries, from batteries and construction to radiation shielding and cable sheathing. Given its widespread applications and importance, ensuring the quality of primary lead is essential. To maintain the highest quality and safety standards, the BIS certification for Primary Lead has now become mandatory in India.
In this blog, we'll dive into the details of the BIS certification process, the role of the Indian Standard for Primary Lead (IS 27:2023), and the implications of the latest government regulations for manufacturers. We'll also explore the benefits of obtaining ISI certification for Primary Lead and displaying the trusted ISI mark.
In an important move to strengthen quality control, the MINISTRY OF MINES issued the Primary Lead (Quality Control) Order, 2025. Under this order, manufacturers of Primary Lead are now mandated to obtain BIS certification for Primary Lead. Additionally, all certified products must bear the Standard Mark (ISI mark) under a license from the Bureau of Indian Standards, following Scheme-1 of Schedule-II of the Bureau of Indian Standards (Conformity Assessment) Regulations, 2018.
This regulation ensures that only high-quality, standardized primary lead products are manufactured, imported, and sold within the country, protecting industries and consumers alike.
The Bureau of Indian Standards (BIS) is India's national body responsible for establishing and enforcing quality standards across multiple sectors. The BIS certification for Primary Lead confirms that the material complies with the specifications outlined in IS 27:2023.
Manufacturers who secure this certification are allowed to use the ISI mark on their products — a mark recognized throughout India as a symbol of trust, quality, and compliance.
The Indian Standard for Primary Lead (IS 27:2023) lays down comprehensive specifications covering:

With the introduction of the Primary Lead (Quality Control) Order, 2025, obtaining the BIS certification for Primary Lead is now a legal necessity. By aligning products with the Indian Standard for Primary Lead (IS 27:2023) and securing the ISI certification for Primary Lead, manufacturers can ensure market compliance, gain customer trust, and enhance their competitive position.
Displaying the ISI mark certification not only affirms a commitment to quality but also ensures the long-term success and credibility of businesses in the evolving industrial landscape.
