Chapter 73 of the Harmonized System of Nomenclature (HSN) is titled “Articles of iron or steel”. It is part of Section XV, Base Metals & Articles Thereof, together with Chapter 72 (iron and steel), Chapter 74 (copper and articles thereof), Chapter 75 (nickel and articles thereof), Chapter 76 (aluminium and articles thereof), Chapter 78 (lead and articles thereof), Chapter 79 (zinc and articles thereof), Chapter 80 (tin and articles thereof), Chapter 81 (other base metals; cermets; articles thereof), Chapter 82 (tools, implements, cutlery, spoons and forks, of base metal) and Chapter 83 (miscellaneous articles of base metal).

The chapter is divided into 26 headings, from 7301 (sheet piling of iron or steel) to 7326 (other articles of iron or steel). The headings with the most codes that people search for are tube or pipe fittings (for example, couplings, elbows, sleeves), of iron or steel (7307), screws, bolts, nuts, coach-screws, screw hooks, rivets, cotters, cotter-pins (7318), tubes, pipes and hollow profiles, seamless, of iron (other than cast iron) or steel (7304), table, kitchen or other household articles and parts thereof, of iron or steel (7323) and other articles of iron or steel (7326).

Note 2 defines “wire” in this chapter as hot- or cold-formed products of any cross-sectional shape, none of whose cross-sectional dimensions exceeds 16 mm, and Note 1 defines cast iron by reference to the definition of steel in Chapter 72.

Every heading is listed below. Under each are the codes that have their own page on Laabam One, 43 codes in this chapter, each with its full classification: its chapter, heading and sub-heading, and the codes beside it.

Every code in this chapter begins with 73: four digits make a heading, six a sub-heading, and eight a tariff item of India's Customs Tariff. How many of those digits a GST tax invoice shows depends on the business, not the goods: under Notification No. 78/2020 – Central Tax, from 1 April 2021, four digits where aggregate turnover in the previous financial year was up to ₹5 crore, and six above it. Up to ₹5 crore, the code may be left off invoices to unregistered buyers.

No GST rate is shown here. GST rates were revised in September 2025, and a rate appears on this site only once it has been checked against the CBIC rate notifications.
