High-strength deformed stainless steel wires and bars are crucial building materials for a variety of construction and infrastructure projects. By enhancing concrete structures' strength, longevity, and safety, its use promotes creative design and lessens the negative effects of construction on the environment. These supplies are essential for building durable, robust, and sustainable infrastructure that satisfies the requirements of contemporary building initiatives.
Under IS 16651: 2017, all high-strength deformed stainless steel bars and wires for concrete reinforcement are now required to be part of the ISI Certification Scheme.
1. The following strength categories of high-strength deformed stainless steel bars and wires are covered by this standard's specifications and testing procedures for use as concrete reinforcement:
NOTE: The numbers in N/mm2 that follow the symbol SS are the minimum 0.2 percent proof stress or yield stress that is required.
2. Solid stainless steel bars and wires that have undergone hot rolling or cold working to generate ribs or deformations are covered by this standard.
3. Hot-rolled steel that has not been heat-treated afterward or hot-rolled steel that has been annealed and cold-worked thereafter are both covered by this standard. The manufacturer has the last say over the production process.
4. The criteria of this standard also apply to reinforcing bars and wires that are delivered in coil form; nevertheless, the straightened product must comply with these standards.
5. This standard does not accept deformed stainless steel reinforcing bars or wires made from material whose metallurgical history is unknown and not properly documented, or from rerolled final products like plates.
Without the ISI Mark, this product cannot be marketed, imported, or exported into the Indian consumer market.
About ISI / BIS Certification
Indian Standards Institute, or ISI was renamed the Bureau of Indian Standards (BIS) in 1987. The official mark that the Bureau of Indian Standards provides for manufacturers of various goods is the ISI Mark. It is used to indicate compliance with Indian standards (IS) set by the Bureau of Indian Standards (BIS) and has been used as a conformity marking for industrial products. Manufacturers received permission from BIS to use the ISI Mark on items that comply with relevant Indian requirements through the product certification program.
Only manufacturers (domestic or foreign) who produce the finished product will be awarded ISI Certification. This will not be given to any product importers, traders, dealers, or distributors.

There are two approaches for Indian manufacturers to become certified with the ISI Mark:
Regular Procedure
With the possible exception of cases deemed "All India first," which might take up to 180 days, the licensing procedure is expected to be finished in 120 days. This timeline starts on the day the application is received, assuming that at different points in time the documentation, unit assessment, and product conformance are all deemed acceptable.
Step 1: Manufacturing Unit Customization in Compliance with Applicable Indian Standards
Step 2: Submission of the Application Form

Simplified Procedure
This is a much faster process than the standard procedure. After a factory inspection is deemed satisfactory and the initial evaluation establishes that the sample complies with the applicable Indian Standard(s), the license application process is expected to be finished in 30 days.
Step 1: Adapting the Manufacturing Unit to Comply with the Relevant Indian Standard
Step 2: Sample Testing
