Hot rolling produces flat steel sheets or strips with precise dimensions and characteristics, which are known as hot-rolled mild steel sheets and strips. To make storage and shipping easier, these materials are coiled.
Cold-reduced tin plates and cold-reduced black plates are manufactured using hot-rolled mild steel sheets and strips as necessary raw materials. They are picked because they are ideal for further processing and cold reduction because to their strength and formability. The material's thickness and surface properties are improved by the cold reduction process, making it suitable for the unique demands of applications involving tinplate and black plate. The industrial, manufacturing, and packaging sectors depend heavily on these steel goods.
The criteria and guidelines that direct the manufacturing, quality control, and application of this particular type of steel product in various industrial applications are outlined in the specifications for hot-rolled mild steel sheet and strip in coil form for cold-reduced tinplate and cold-reduced black plate. Following these guidelines encourages effective trading and adherence to legal obligations.
According to IS standard IS 2385: 1977, all requirements for hot-rolled mild steel sheets and strips in coil form for cold-reduced tinplate and cold-reduced black plate are now part of the required ISI Certification Scheme.
Coils of material that meet this standard's requirements should normally have a thickness of at least 1.8 mm and a width of at least 600 mm.
Different procedures including open hearth, electric furnace, duplex furnace, basic oxygen furnace, or a mix of these processes need be used to create the steel. The material's chemical makeup ought to match the prescribed parameters. There shouldn't be many problems with the sheets and strips, such as laminations, seams, fractures, rolled-in oxides, inclusions, or other flaws that might affect the material negatively during further processing.
Without the ISI Mark, this product cannot be marketed, imported, or exported into the Indian consumer market.
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
