2829.90.05.00 - Potassium bromate

This category encompasses potassium bromate, a chemical compound with the formula KBrO₃. It is a salt of potassium and bromic acid. Within Chapter 28, which deals with inorganic chemicals, potassium bromate is specifically classified under headings related to halates and perhalates of various metals. Its primary uses are as an oxidizing agent, in the production of other bromate compounds, and historically, in the baking industry as a dough conditioner, though its use in food is now restricted or banned in many countries due to health concerns.

The sibling category, 2829.90.25.00, covers sodium bromate. The key distinction lies in the cation: this heading is exclusively for the potassium salt (KBrO₃), whereas the sibling is for the sodium salt (NaBrO₃). Both are bromates, but their distinct chemical compositions necessitate separate tariff classifications.

As this is a leaf node within the HTS, there are no further subdivisions. Classification under 2829.90.05.00 is definitive for potassium bromate. Importers and exporters should ensure the product is indeed potassium bromate and not a mixture or another bromate salt to adhere to correct classification.
