2841.50.91.00 - Other

This HTS classification, 2841.50.91.00, covers "Other" chromates and dichromates, and peroxochromates, falling under the broader category of salts of oxometallic or peroxometallic acids. These are inorganic chemical compounds characterized by the presence of chromium in an oxidized state, forming salts with oxometallic acids (like chromic acid) or peroxometallic acids. This designation applies to those chromates, dichromates, and peroxochromates that are not specifically enumerated elsewhere within the 2841.50 subheadings.

The distinction from sibling categories, such as 2841.50.10.00 (Potassium dichromate), lies in the specific chemical composition. While potassium dichromate is a distinctly defined compound, this "Other" category captures a broader range of chromates and dichromates where the cation is not potassium, or includes peroxochromates, which are less common and possess peroxide linkages. Classification here relies on the absence of specific mention in preceding subheadings and the chemical confirmation of a chromate, dichromate, or peroxochromate structure.

As this is a leaf node, there are no further subcategories. Therefore, classification within 2841.50.91.00 is the final determination for eligible goods. Practical classification will involve verifying the chemical identity of the product to confirm it is indeed a chromate, dichromate, or peroxochromate, and then ensuring it does not fit any more specific description within the broader 2841.50 range. Examples might include sodium dichromate, ammonium dichromate, or various metal chromates not listed individually.
