Silicomanganese is one of the most popularly used ferroalloys in the manufacture of steel. This is due to the reason that the use of silicomanganese ensures increased strength, hardness, and durability of the steel products. The production of silicomanganese takes place through the smelting process of manganese ore, silica, and carbon. The use of silicomanganese is essential in enhancing the mechanical properties and ensuring improved performance of structural steel, rails, pipelines, and industrial metal parts.
BIS certification is mandatory for silicomanganese since its chemical composition and metallurgy have a direct effect on the quality of the steel products. As per IS 1470: 2025, manufacturers need to follow some specific testing criteria, such as percentage of manganese and silicon in the alloy, purity of the alloy, and uniformity in its physical form. Obtaining the BIS certification for the alloy is mandatory to sell it in the marketplace.
What is IS 1470: 2025
This is the Indian Standard for Silicomanganese used in steelmaking applications. It mentions the quality requirements and testing criteria to ensure consistency in metallurgical processes. As per the BIS (Bureau of Indian Standards), Silicomanganese is:
- Evaluated for metallurgical suitability
- Checked for impurity control
- Tested for chemical composition accuracy
- Assessed for physical and quality consistency
Ferro Manganese Silicon BIS Approval Eligibility Details
BIS authorisation under IS 1470: 2025 is required for businesses involved in manufacturing, importing, or supplying SiMn alloy in India.
Applicable to:
- Manufacturers (India) - Must get BIS approval if the alloy additives for steel production are covered under QCO.
- Foreign Manufacturers - Need certification to export the product to India.
- Importers/Brand Owners - Must ensure that the products are BIS-certified before sale.
- Sellers/Distributors - Should only sell certified Silicon Manganese alloy.
Testing and Inspection Requirements
To ensure consistent quality of Silicomanganese used in steelmaking applications, the Bureau of Indian Standards outlines the minimum requirements under IS 1470: 2025. This certification ensures that manufacturers meet the chemical and quality standards for ferroalloy production.
The BIS testing parameters and quality checks for the Manganese-based ferroalloy are listed below:
BIS Approval Steps for Silicomanganese Ferroalloy
The BIS Authorisation process ensures that the Deoxidizer alloy meets the performance standards for effective use in steelmaking. This process is set by the Bureau of Indian Standards (BIS) and includes the following steps:
- Online Registration: Manufacturers register on the BIS Manak portal by submitting company, factory, and product details. Foreign manufacturers must appoint an Authorized Indian Representative (AIR).
- Testing at BIS-Approved Laboratory: Product samples are tested in BIS-approved laboratories for chemical composition, impurity levels and physical properties.
- Application Submission: The application is submitted along with test reports, technical documents, and factory details. Foreign manufacturers must also provide AIR-related documents.
- Factory Inspection: The Bureau of Indian Standards officials inspect the manufacturing units to verify the production process, safety measures, and quality control system.
- Grant of BIS License: After successful verification of documents, testing and inspection, BIS grants the certification license under Scheme-I.
- Use of ISI Mark: Once the license is granted, the manufacturer can use the ISI mark on the product with a CM/L number, confirming that the product meets BIS standards.

Marking Requirements & License Validity
Marking Requirements
Once a manufacturer obtains BIS approval, the ISI Mark for Silicomanganese metal alloy must
be clearly and permanently marked on its packaging or on the product. Along with the ISI Mark,
essential details such as the manufacturer’s identification and licence number (CM/L) must be
marked. This ensures the product complies with all performance and quality standards.
Additional details are mentioned below:
| Requirement | Details |
|---|
| ISI Mark | Indicates that the product is BIS certified and conforms to standards |
| Standard Number | IS 1470: 2025 |
| CML Number | Certification Marks License (CML) number issued by BIS |
| Manufacturer Details | Name of manufacturer or registered trademark |
| Batch / Date | Batch number, heat number, or manufacturing date for traceability |
Note: Marking is typically applied using durable stamping, tagging, or permanent printing to ensure clear identification during handling, storage, and transportation, as per BIS marking requirements.
