2834.29.20.00 - Of strontium

This HTS category, 2834.29.20.00, specifically classifies nitrates of strontium. These are inorganic chemical compounds where strontium is bonded to the nitrate ion (NO₃⁻). Examples include strontium nitrate, which is commonly used in pyrotechnics to produce a brilliant red color, as well as in various industrial applications such as the production of glazes for ceramics and in certain types of glass manufacturing.

When classifying nitrates under 2834.29, it is crucial to distinguish this subheading from its siblings based on the cation present. Subheadings 2834.29.05.00 (of bismuth) and 2834.29.10.00 (of calcium) cover nitrates where the metallic element is bismuth or calcium, respectively. This subheading is specifically reserved for nitrates where strontium is the defining metallic component. The catch-all category 2834.29.51.00 (Other) would encompass nitrates of metals not otherwise specified in this grouping.

As this is a leaf node within the HTS classification system, there are no further subdivisions under 2834.29.20.00. Therefore, the classification criteria are limited to the identification of strontium as the metallic element within the nitrate compound. The physical form (e.g., powder, crystal) or purity level of the strontium nitrate would not typically lead to a different HTS classification at this level, provided it is indeed a nitrate of strontium.
