2834.29 - Other:

This HTS category, 2834.29, encompasses "Other nitrates" that are not specifically listed under the preceding subheadings within the nitrites and nitrates chapter. It covers a broad range of inorganic nitrate salts beyond those of potassium, which are classified under 2834.21. The defining characteristic of these substances is their chemical composition as nitrate salts of various metallic or metalloid elements.

Unlike its sibling category, 2834.21, which specifically enumerates nitrates of potassium, this heading serves as a residual category for all other metallic or metalloid nitrates not otherwise specified. This ensures that all inorganic nitrates are appropriately classified within the tariff schedule, preventing misclassification due to the absence of a specific entry.

The subcategories within 2834.29 further refine the classification based on the specific cation present in the nitrate salt. These include nitrates of bismuth (2834.29.05.00), calcium (2834.29.10.00), and strontium (2834.29.20.00). For any other metallic or metalloid nitrate not listed individually, the residual subheading 2834.29.51.00, "Other," will apply. This hierarchical structure allows for precise identification of a wide array of inorganic nitrate compounds.
