Strontium Carbonate Powder (99% Purity)
High-purity strontium carbonate (SrCO3) powder used primarily in the production of strontium chemicals and as a flux in ceramics. It falls under HTS 2836.92.00.00 as a chemically defined carbonate of strontium, explicitly listed in the 'Other' category of carbonates per Chapter 28 notes. This inorganic compound meets the criteria for classification in this heading, excluding organo-inorganic compounds.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing barium or mixed with other alkaline earth metals
Complex salts of strontium with barium fall under heading 2833 for barium carbonates if predominantly barium-based, per notes on double salts in 2842.
If chemically modified or in mixtures for specific industrial use
Non-chemically defined preparations or mixtures of strontium carbonate not meeting pure compound criteria shift to Chapter 38 as chemical preparations.
If in natural mineral form like strontianite ore
Natural strontium carbonate minerals (strontianite) are classified as non-agglomerated ores under Chapter 25, not refined chemical compounds.

Import Tips & Compliance
• Verify purity and chemical composition via lab analysis to confirm 'chemically defined' status per Chapter 28 Note 1; ensure SDS and COA documentation for customs clearance
• Avoid misclassification as organo-inorganic compounds (Chapter 29)
• Watch for strontium content thresholds to prevent reclassification under rare earths
