- BIS Certification for Specification for Mild Steel Wire as per IS 1673:1984( indicates the product is safe, reliable, and of a quality suitable for cold-heading operations.
- To get the green light, producers have to undergo tests in a laboratory approved by the BIS and pass a factory inspection.
- IS 1673:1984 specifies the aspects of the material including the chemical composition, the tensile properties, and the surface finish.
- Using certified wire helps in the reduction of the defects during the forming process and thus the wire can be used in the production of automotive and industrial fasteners.
- BIS certification improves credibility, export readiness, and tender eligibility.
Introduction
A fastener manufacturer from Ludhiana recently contacted us after repeatedly being rejected by an automotive buyer whose new supply norms required BIS Certification for the Specification for Mild Steel Wire, Cold Heading Quality, as per IS 1673:1984. Their wire behaved inconsistently during the forming process, and without certification, they were losing orders they had supplied for years. This is now common across fastener, electrical, and engineering sectors, where buyers want predictable, standard-compliant raw material. IS 1673:1984 acts as a filter for quality, covering chemistry, strength, and surface finish essential for cold-heading operations. For many manufacturers, the certification has shifted from optional to essential, especially when competing in regulated or export-driven markets. Bureau of Indian Standards
What is IS 1673:1984?
IS 1673:1984 outlines the characteristics of the material that a wire made of mild steel for the cold headed wire should meet. Such wire should be able to go through upsetting, forging, and forming operations without the appearance of cracks, therefore the requirement is mainly for a well-defined chemical composition, controlled mechanical properties, and a good surface finish. The producers who provide the product line of the fastening system, rivets, screws, and precision-formed components use this standard as a basis for a consistent performance of different batches.
Key points:
• Defines chemical composition limits for low-carbon steel suitable for deformation.
• Covers tensile strength, elongation, and reduction of area needed for cold heading.
• Specifies dimensional tolerances and surface finish requirements to reduce forming defects.
• Includes tests such as bend test, torsion test, and upset test to confirm ductility. ISI MARK
• Serves as the base requirement for BIS certification for cold-heading quality wire in India.
Why is BIS Certification Mandatory
BIS Certification is required for Mild Steel Wire under IS 1673:1984 mainly because the metal is the primary factor that determines the safety, the dependability, and the performance of the components that are cold-headed. The law serves as a gatekeeper that lets only those wires that meet the standards be manufactured, marketed, or brought into the country thereby the users and producers are guaranteed quality and are free from the risk of product failures.
Keypoints:
• Prevents the supply of sub-standard wire in critical fastener and engineering applications.
• Ensures consistent chemistry, ductility, and tensile properties required for cold heading.
• Reduces production defects, tool damage, and rejection rates for downstream manufacturers.
• Required by major OEMs and government tenders for traceability and quality assurance.
• Mandatory under BIS rules, making certification essential for market entry.
Importance and Benefits of BIS Certification

Frequently Ask Questions
What does IS 1673:1984 specify for Mild Steel Wire?
The Indian Standard specifies the chemical, mechanical, and surface characteristics of mild steel wire of a quality suitable for cold-heading.
Is BIS certification necessary for the IS 1673:1984 wire?
It is a requirement to have such certification if the production, selling, or importing of cold-heading quality mild steel wire take place in India.
Under this standard, who is obliged to obtain BIS certification?
Obtainers of the certificate are the manufacturers of mild steel wire, fastener producers from wire drawing by the in-house method, and importers of such wire into India.
What are the required tests for this certification?
The tests cover tensile strength, elongation, bend test, torsion test, upset test, and chemical composition analysis.
What is the duration of the BIS certification procedure?
It usually takes 20 to 30 days and is dependent on the time for testing and the scheduling of the BIS inspection.
Are foreign manufacturers eligible to apply for a BIS certification?
Certainly, but to manage the application and ensure compliance, they need to designate an Authorized Indian Representative (AIR).
