One kind of steel product that is produced by cold rolling is called cold-reduced carbon steel sheet. In this process, hot-rolled steel that was first produced at high temperatures is passed through a succession of rollers at room temperature to reduce thickness and improve surface smoothness. Steel that has undergone cold reduction has improved surface quality and dimensional precision, making it more useful in a variety of settings.
One kind of steel product made by the hot-rolling method is a hot-rolled carbon steel sheet. Steel slabs or billets are heated to high temperatures in this process, after which they are rolled into sheets at high temperatures. Compared to cold-rolled steel, this process produces thicker sheets, which usually have a black oxide scale on their surface.
Specialized steel products called cold-reduced and hot-rolled carbon steel sheets are intended for usage in situations where porcelain enameling is used to provide a long-lasting and eye-catching finish. The steel surface is first coated with a glassy enamel coating, which is subsequently burned at high temperatures to provide a smooth, glossy, and corrosion-resistant finish.
The performance and lifespan of consumer appliances, cookware, sanitary ware, and ornamental items are enhanced by the use of carbon steel sheets that have been hot-rolled and cold-reduced. They are used in many sectors where quality and appearance are important because of their resistance to corrosion and simplicity of maintenance.
Under IS standard IS 9485: 1980, all varieties of hot-rolled and cold-reduced carbon steel sheets for porcelain enamelling are covered by the required ISI Certification Scheme.
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
