2610.00.00.20 - Having a chromium content equivalent to not more than 40 percent chromic oxide (Cr2O3)

This HTS category, 2610.00.00.20, specifically covers chromium ores and concentrates that have a chromium content equivalent to no more than 40 percent chromic oxide (Cr2O3). These are raw or semi-processed mineral materials where the proportion of chromic oxide is relatively low, making them distinct from other chromium ore classifications based on their chemical composition.

The primary distinguishing factor for this category is the specific limit of chromic oxide content. It differentiates these ores from sibling categories 2610.00.00.40, which applies to ores with a chromium content equivalent to more than 40 percent but less than 46 percent chromic oxide, and 2610.00.00.60, which encompasses ores with 46 percent or more chromic oxide. Therefore, precise chemical analysis is crucial for correct classification.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification within 2610.00.00.20 is determined solely by the specified chromic oxide percentage. Examples of materials falling under this heading would include certain types of low-grade chromite ores or concentrates that have undergone initial processing but do not meet the higher chromium content thresholds of other classifications. The purpose of these ores is typically as a source of chromium for various industrial applications, though the lower concentration may dictate specific downstream uses or require further beneficiation.
