2601 - Iron ores and concentrates, including roasted iron pyrites:

HTS Code 2601 encompasses iron ores and their concentrated forms, as well as roasted iron pyrites. This category is crucial for identifying and classifying raw materials primarily used in the production of iron and steel. The key characteristic for inclusion under this heading is the presence of iron as the principal metallic component, regardless of its initial state of extraction or preliminary processing.

While HTS Code 2601 deals with iron-bearing mineral materials, it is distinct from other categories within Chapter 26 which cover different types of ores, slag, and ash. For instance, it does not include metallic iron itself (which would fall under Chapter 72) or ores of other base metals like copper or aluminum. Its placement within Section V confirms its focus on mineral products rather than finished or semi-finished goods.

Within HTS Code 2601, a further distinction is made between iron ores and concentrates that are not roasted iron pyrites, and roasted iron pyrites. This subdivision allows for more precise classification based on the specific form and processing of the iron-bearing material, which can have implications for duty rates and trade regulations. The subcategory for roasted iron pyrites specifically addresses a concentrated form of iron sulfide that has undergone roasting to remove sulfur and produce a more stable iron oxide material.
