Steel tubes for mechanical and general engineering purposes must carry the ISI mark. The Indian Standard for it is IS 3601. The legal order is: Steel and Steel Products QCO (2012-2024 series, Ministry of Steel); phased coverage. You cannot make, import, sell or store this product for sale in India without a valid BIS licence.
How it works: a BIS-approved lab tests your samples against IS 3601. A BIS officer then visits your factory. If everything is in order, BIS gives you a licence. You can then print the ISI mark with your licence number (CM/L number). Factories outside India apply under the Foreign Manufacturers Certification Scheme (FMCS). They must also name a representative in India, called an Authorised Indian Representative (AIR).
Every year you pay BIS a minimum marking fee. It is ₹14,600 for micro firms and ₹73,000 for large firms. The fee also depends on how much you make: ₹8.70 per tonne. You pay whichever amount is higher. Lab testing costs about ₹6,000 – ₹12,000 per sample, based on quotes from 8 BIS-approved labs. These prices are a guide only and do not include GST.
