Overview

This HTS classification, 2918.13.10.00, specifically covers Potassium antimony tartrate, commonly known as Tartar emetic. This compound is a salt of tartaric acid where both the acidic protons of tartaric acid have been replaced by potassium and an antimony group. Its primary characteristic is the presence of antimony, which distinguishes it from other tartaric acid salts.

It is important to differentiate this classification from its siblings. 2918.13.20.00 covers Potassium bitartrate (Cream of tartar), which is an acidic salt of tartaric acid. 2918.13.30.00 pertains to Potassium sodium tartrate (Rochelle salts), a double salt of potassium and sodium tartrate. Lastly, 2918.13.50.00 encompasses "Other" salts and esters of tartaric acid not otherwise specified. Therefore, the presence of antimony is the definitive factor for classification under 2918.13.10.00.

As this classification represents a leaf node within the HTS system, there are no further subcategories. The classification of Potassium antimony tartrate is specific to this HTS code, indicating that goods meeting the chemical and functional definitions of Tartar emetic are exclusively classified here.
