Zinc Chloride Anhydrous
Pure anhydrous zinc chloride (ZnCl2) is a white, hygroscopic, crystalline compound used in chemical synthesis and as a flux in soldering. It falls under HTS 2827.39.65.00 as a chemically defined chloride of zinc, distinct from other metal chlorides in heading 2827. This subheading specifically covers zinc chlorides not elsewhere specified.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing more than 74 Bq/g radioactivity
Radioactive zinc chlorides fall under heading 2844 per Chapter 28 note 6, prioritizing nuclear materials over simple chlorides.
If sold as formulated flux mixture for retail soldering kits
Complex preparations or mixtures not purely chemically defined zinc chloride classify as chemical preparations in 3824.
If in form of sterile, medicinal-grade solution
Pharmaceutical-grade salts may shift to 2843 if presented solely for medicinal use rather than industrial chemical.

Import Tips & Compliance
• Verify purity and provide Certificate of Analysis (COA) to confirm it's chemically defined zinc chloride per Chapter 28 notes
• Ensure packaging prevents moisture absorption due to hygroscopic nature; declare exact concentration to avoid reclassification
