About HTS Chapter 73

HTS Chapter 73 - Articles of iron or steel - organizes 968 tariff classifications in the US Harmonized Tariff Schedule. Of these, 250 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 73 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 1.1%, with the highest individual rate reaching 12.5%. 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.

Use this chapter page as the entry point for classifying any product that falls under articles of iron or steel. The tree below preserves the HTS indentation hierarchy (heading → subheading → tariff line), so you can narrow from broad category to specific 8-10 digit code. All data comes from the US International Trade Commission (USITC) HTS 2026 Basic Edition, the official schedule of import duties used by US Customs and Border Protection.
