2617 - Other ores and concentrates:

This HTS category, 2617, encompasses metallic ores and their concentrates that are not specifically enumerated in other headings within Chapter 26. It serves as a residual category for valuable mineral substances that have undergone initial processing to increase their metal content but do not fall into more precisely defined classifications. The primary distinguishing feature of goods classified here is their metallic mineral content, which differentiates them from non-metallic mineral products or manufactured goods.

Unlike sibling categories such as those for live animals or agricultural products found at higher levels of the HTS, heading 2617 focuses exclusively on unprocessed or semi-processed mineral substances. It specifically excludes ores and concentrates of metals covered by other headings, such as lead, zinc, copper, aluminum, or precious metals. Therefore, the key to classifying within 2617 lies in identifying the base metal present and ensuring it is not subject to a more specific HTS code.

The subcategories within 2617 provide further specificity for the types of metallic ores and concentrates that fall under this general heading. For instance, 2617.10.00.00 specifically identifies antimony ores and concentrates, recognizing the distinct importance and market for this particular metal. The residual subheading, 2617.90.00, captures all other metallic ores and concentrates not otherwise specified, emphasizing the need for detailed analysis of the mineral composition and origin when classifying.
