About HTS Chapter 26
HTS Chapter 26 - Ores, slag and ash - organizes 143 tariff classifications in the US Harmonized Tariff Schedule. Of these, 48 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 26 sits within Section V (Mineral Products), 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 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 ores, slag and ash. 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.
