Sodium Bisulfate Monohydrate
Sodium bisulfate monohydrate (NaHSO4·H2O), also known as niter cake, is an acid salt derived from sodium sulfate. It is used primarily for pH adjustment in swimming pools, as a cleaning agent, and in food processing applications. As a sodium sulfate derivative not elsewhere specified, it falls under tariff item 2833.19.00 for other sodium sulphates.
2833.19.00Sodium Sulfate Anhydrous (Salt Cake)
Sodium sulfate anhydrous, also called salt cake, is a white crystalline powder widely used in the glass, paper, and detergent industries as a filler and fluxing agent. It is a separate chemically defined compound of sodium sulfate, not a hydrate, and is classified as 'other' sodium sulphates under tariff item 2833.19.00.
2833.19.00Sodium Sulfate Decahydrate Technical Grade
Sodium sulfate decahydrate technical grade is a hydrated form of sodium sulfate, often used in heat packs and as a laboratory reagent. It does not meet the specific criteria for Glauber's salt in terms of purity or form, so it is classified as 'other' sodium sulphates under tariff item 2833.19.00. The product is a separate chemically defined compound with added water of crystallization.
