Chromium Potassium Sulfate Dodecahydrate from Japan

This double salt, KCr(SO4)2·12H2O, is a chrome alum used in analytical chemistry and trivalent chromium plating baths. It qualifies under HTS 2833.29.40.00 as a sulfate of chromium, though borderline with 2842 for complex salts. Its violet crystals are standard in lab reagents.

Import Tips

Provide crystallographic data or formula confirmation to distinguish from true double salts in 2842

For lab imports, include end-use statements to avoid industrial chemical scrutiny
