2815.12.00.00 - In aqueous solution (Soda lye or liquid soda)

This HTS classification, 2815.12.00.00, specifically covers sodium hydroxide when it is presented in an aqueous solution. This form is commonly known as soda lye or liquid soda. It is important to distinguish this classification from its sibling category.

While 2815.11.00.00 encompasses solid forms of sodium hydroxide (e.g., flakes, pellets, or solid blocks), this category exclusively addresses the liquid form. The primary differentiator for classification purposes under this code is the physical state of the sodium hydroxide. The concentration of the aqueous solution is not a determining factor for this specific code, as long as it is presented in liquid form.

As a leaf node within the HTS, there are no further subcategories directly under 2815.12.00.00. Therefore, classification hinges on the precise identification of the product as aqueous sodium hydroxide, distinct from any solid presentations.
