Introduction
In late 2023, a Jaipur-based zinc alloy importer found his shipment stuck at Nhava Sheva port. The reason? His supplier didn’t have the mandatory BIS certification for refined zinc under IS 209:2024. The customs authorities refused clearance, citing non-compliance with India’s Refined Zinc Quality Control Order. This halted operations, cost the trader ₹18 lakhs in losses, and forced him to find a new BIS-certified supplier in days.
This situation is not unique. With India tightening its technical regulations on base metals, every business dealing with refined zinc—from importers to galvanizers—must meet BIS standards or face disruption.
In this guide, we’ll walk you through everything you need to know about BIS certification for refined zinc, especially under the latest IS 209:2024 standard.
What Is Refined Zinc?
High Purity Zinc is the highly purified form of zinc metal that is primarily used in:
- Galvanizing iron and steel
- Making die-cast alloys
- Making brass and other zinc alloys
- Creating an industrially used type of zinc compound.
The refined zinc needs to be made at national standards to ensure the consumer continues to have the same composition-hazardous impurities as the insulated ones; that is, IS 209:2024.
Introduction to IS 209:2024
The IS 209:2024 is the revised Indian Standard devised by BIS that specifies the quality, purity, chemical composition, and testing parameters related to refined zinc.
This standard ensures that the zinc produced or imported into India has very tight quality parameters while specifying very high minimum purity of zinc (99.95%).
It also specifies permissible limits for lead, iron, cadmium, and other impurities as follows:
Conditions regarding packaging,
Labeling, and storage.
The purpose of this standard is to ensure quality control in refined zinc and in the protection of the consumer and the downstream industry against products of inferior quality or contamination.
The Refined Zinc Quality Control Order, 2025
The Ministry of Mines , Government of India, issued the Refined Zinc (Quality Control) Order, 2025, under the Bureau of Indian Standards Act, 2016.
Applicability:
- Indian manufacturers
- Importers
- Traders and stockists
- Bulk industrial buyers
Violation of the order will invite punitive actions under the BIS Act, which will include penalties and confiscation of goods.
Why Is Certifying BIS for Refined Zinc Important?
The BIS mandatory certification for refined zinc would serve a number of important purposes:
1. Assurance of Quality
Manufacturers are supposed to follow security specifications as laid down by the BIS, thus preventing entry into the supply chain of lower-grade, contaminated zinc.
2. Strengthens Consumer Confidence
The ISI indication in a product provides comfort to the customer on safety and conformity as per Indian standards.
3. Ensures Fair Play
Every supplier is now subject to the same rigorous quality standards, regardless of where they are sourced-from – national or international.
4. Prevents Substandard Imports from Being Dumped
The certification serves a regulatory check against the import of low-quality zinc into the country.
Who Needs BIS Certification for Refined Zinc?
Any person who manufactures, imports, stocks, distributes, or sells refined zinc within India should obtain BIS certification.
Categories of Applicants:
- Domestic manufacturers (Hindustan Zinc Ltd, Met Trade India, etc.)
- Overseas manufacturers (exporting to India)
- Importers and distributors (acting as Authorised Indian Representatives)
- Galvanizing units, automobile suppliers, infrastructure companies
So if you are going to use zinc as either an input for alloying or as a final product, it is imperative that it gets certified.

Compulsion in adopting the BIS certification for refined zinc under IS 209:2024 is an important milestone in the quality control ecosystem of India. As industries become more reliant on metals and standards for safety and efficiency, BIS conformance is no longer an option for them. Such standards exist widely for the most common metals like copper, aluminum, and steel, and extend into more niche metals.
For any domestic manufacturers and overseas exporters, this is the right time to start the process of certification. The right partner, like Diligence Certification, will make your compliance pathway smooth, timely, and trustworthy.
