About Duty Rates: Rates are divided into Column 1 and Column 2. Column 1 is subdivided into General (normal trade relations rates for all countries not eligible for special programs) and Special (preferential rates for countries with free trade agreements or preference programs). Column 2 rates apply to products from Cuba, North Korea, Belarus, and Russia. When no special rate exists for a classification, General rates apply.

Overview

This HTS category, 2834.29.10.00, specifically classifies nitrates of calcium. These are inorganic chemical compounds where the nitrate anion (NO₃⁻) is bonded to calcium cations (Ca²⁺). Common forms include calcium nitrate, which often appears as a hydrated crystalline solid and is widely used as a fertilizer due to its readily available calcium and nitrogen content. It also finds applications in pyrotechnics and concrete admixtures.

This category is distinguished from its sibling categories by the specific metal cation. While 2834.29.05.00 covers nitrates of bismuth and 2834.29.20.00 pertains to nitrates of strontium, this classification is exclusively for calcium-based nitrates. The "Other" category (2834.29.51.00) serves as a residual for any other nitrates not specifically enumerated elsewhere at this level.

As this is a leaf node, there are no further subcategories within this specific HTS code. Classification within 2834.29.10.00 is determined solely by the presence of calcium as the cation in the nitrate compound, aligning with the broader grouping of "Other nitrates" under the nitrites and nitrates chapter.
