Nickel Ammonium Sulfate
Nickel ammonium sulfate ((NH4)2Ni(SO4)2·6H2O) is a double salt used in analytical chemistry and electroplating baths. Under Chapter 28 Note 5, double or complex salts are classified in heading 28.42, but this product is a true double sulfate of nickel and ammonium, and per Note 5, double salts are to be classified in heading 28.42. However, the tariff item 2833.24.00 covers 'of nickel' sulphates, and the product is a sulfate of nickel. Given the legal note, this product should be classified under 2842.90.00 as a double salt, not under 2833.24.00.
