HTS Chapter 72 - Iron and steel - organizes 949 tariff classifications in the US Harmonized Tariff Schedule. Of these, 262 carry explicit duty rates at the tariff-line level, meaning importers can look up a specific Column 1 General (MFN) rate for every qualifying shipment. Chapter 72 sits within Section XV (Base Metals and Articles of Base Metal), which groups commercially related product categories together.
The average general duty rate across all tariff lines in this chapter is 0.3%, with the highest individual rate reaching 10%. Duty burden varies widely across tariff lines within this chapter, classification precision matters. Below, each line links to its individual detail page showing General, Special (FTA), and Column 2 rates.
