About HS Code 283319
This category covers sodium sulphates that are not disodium sulphate, primarily referring to sodium bisulphate (sodium hydrogen sulphate). Sodium bisulphate is an acidic salt widely used as a pH reducer in various applications, including swimming pool chemicals, metal finishing, and as a cleaning agent. It also finds use in the food industry as a leavening agent and preservative. The international trade of these "other" sodium sulphates is driven by demand from specialty chemical manufacturers, pool chemical suppliers, and food processors. Unlike the high-volume disodium sulphate, trade in sodium bisulphate is often more specialized, catering to specific industrial needs where its acidic properties are advantageous. Key considerations in trade include purity levels, granular size, and packaging, as these can vary significantly based on the end application.
Products Under This Code

Common Misclassification
This code is distinct from 283311 (disodium sulphate) by the presence of hydrogen in the chemical formula (NaHSO4 vs Na2SO4). It could also be confused with other acid salts or even some sulphites if not carefully identified by its specific chemical structure.
Products Classified Under 2833.19
Industry
