2834.29.51.00 - Other

This category, HTS Code 2834.29.51.00, encompasses "Other" inorganic nitrates not specifically enumerated elsewhere within the broader heading 2834.29. This classification applies to nitrates of various metals and metalloids that do not fall under the preceding subcategories, such as those of bismuth, calcium, or strontium. The primary characteristic for inclusion here is that the substance is a nitrate salt of a chemical element or compound not explicitly listed in the more specific classifications within this group.

To clarify, this "Other" category serves as a residual for any remaining inorganic nitrates. For instance, if a particular metal nitrate, such as lead nitrate or zinc nitrate, is not otherwise specified under a more particular HTS code, it would likely be classified under this heading. The distinction lies in the specific cation forming the nitrate salt; if it's not bismuth, calcium, or strontium, and not a nitrate of precious metal, rare-earth metal, radioactive element, or isotope (which are covered elsewhere in Chapter 28), then it falls into this general "Other" designation.

As a leaf node within the HTS structure, 2834.29.51.00 has no further subdivisions. Therefore, classification into this code relies on a process of elimination. Importers and exporters must first review the more specific nitrate categories within heading 2834. If the product does not fit any of those explicitly defined groups, and it is confirmed to be an inorganic nitrate, then this "Other" category becomes the appropriate classification. Examples could include nitrates of metals like magnesium, barium, or aluminum, provided they are not covered by more specific headings or subheadings.
